The steady transition to renewable energy sources has been one of the most noticeable environmental shifts of the last several decades. High pricing and limited supplies have led to a surge in demand for renewable energy sources like solar power. As a result, more and more homeowners are going solar in recent years, and many have taken to searching for reliable inverter battery dealers in Chennai to ensure their solar power system is properly installed and functioning. Industries and corporations have also invested in renewable technologies including wind, biomass, solar, and more out of a need for alternate energy options.
Direct Current power is produced by solar panels by absorbing solar radiation. Direct Current (DC) produced by the solar panels must be changed to Alternating Current (AC) before being utilized by conventional household appliances. That's why there are devices like solar inverters.
Solar Inverters: What is It?
The electricity supplied by solar panels is in the form of direct current (DC), and solar inverters convert this into alternating current (AC) at the proper voltage and frequency. The energy produced by solar inverters may be used either locally in residential infrastructures or sent straight into the commercial power grid for distribution. Selecting the right type of solar inverter is important for optimizing the utility of the produced solar energy.
With the rise in popularity of solar systems over the years, it's crucial to understand how they operate and what characteristics set them apart from one another.
The following are the varieties of solar inverters that are most often seen on the market today:
It is essential to have a knowledge of the function of an inverter in order to fully understand the distinctions between the four. The primary purpose of an inverter is to convert Direct Current (DC) into Alternating Current (AC). With regards to solar power systems, an inverter is crucial because it controls the flow of electricity to the household appliances. Now that we understand what an inverter does, we can dive into the specifics of the various solar inverter options available.
On-grid or Grid-tied Inverter
In solar power systems, on-grid or grid-tied inverters allow for the extra energy to be sent back into the mains power supply. These arrangements are by far the most common in both households and workplaces. When the electricity goes out, they are expected in a way to immediately switch over to the power backup system and disconnect themselves from the grid. With a maximum conversion efficiency of 98% and low minimum starter voltage, they are ideal for use in a wide variety of applications.
One of the most significant benefits of using an inverter that is connected to the grid is the avoidance of the need for batteries. As an alternative, these setups rely on micro or solar inverters to transform the DC power generated by the panels into AC power. The utility grid is used to store any extra power that is created throughout the process, and the customers are given a credit equal to the quantity of energy that is exported. This method is also called "net metering." Having an on-grid connection has several financial benefits, including net metering, higher efficiency rates, and reduced installation equipment expenses.
On-grid solar inverters also have the benefit of being upgradable. You can simply choose the ideal solar inverter for your requirements from the wide variety of options available. However, if the power goes down, a grid-tied system won't work without a battery backup.
Off-grid Inverter
An off-grid system, although being linked to the utility grid, uses solar power to recharge the battery and power the load. It only draws electricity from the grid when the power generated by the solar panels is insufficient to meet the demands of the load or to charge the battery. An off-grid system relies on two things to function properly: a well-thought-out design and an excellent battery system which can supply energy needs even when there's comparatively less sunlight.
There would be no power on dark or cloudy days if there were no battery or other way to store solar energy. The majority of solar energy storage systems for homes not connected to the power grid are designed to charge during the day and discharge at night. These systems may be customized to generate enough electricity throughout the day to meet the demands of a household.
One major drawback of using an off-grid solar inverter is that, if there's gloomy weather for many days, solar power alone may not be enough to meet electrical needs. They are adaptable and may be utilized in any situation. Nevertheless, a battery is required for an off-grid solar inverter to operate.
When it comes to solar inverters, micro inverters are among the most well-liked. This Solar Power System's solar inverters are hardwired to each individual solar panel. They provide a simple plug and play setup and eliminate the need for complicated wiring, making installation a breeze.
Installing solar panels requires a connection to your home's electrical grid, just like any other source of electricity. The drawback of a typical string inverter is that it limits the amount of power that the solar system may generate to that of the least efficient panel. As one panel fails, the others follow suit. Nevertheless, a tiny inverter is set up between each solar panel and the roof. Each solar panel may generate up to its maximum output since each panel comes with its own micro inverter. This means that a micro inverter is more efficient and effective than the traditional string inverters.
Every panel gets the most power possible since there is no weak link in the microinverter system. Also, it makes you safer. As they prevent high-voltage DC from being sent onto the roof, solar panel micro inverters are a more secure option.
Hybrid solar systems
Hybrid solar systems are grid-connected setups that use battery backup. These solar systems may be put together in a variety of different combinations. This solar system collects sunlight throughout the day to use power after the sun goes down. The solar system draws power from the grid and has the capacity to store surplus energy. Batteries may be charged in hybrid systems utilizing less expensive off-peak power. The cost of hybrid systems is much higher than that of standalone or off-grid systems.
Despite their high initial cost, hybrid systems provide users the benefits of both net metering and energy storage in the event of a grid outage. Customers benefit greatly from a constant flow of electricity from a hybrid solar system. Moreover, hybrid systems need significantly less upkeep than traditional diesel-fueled generators.
You can always find a good fit for your needs and budgets among the aforementioned inverters. Prior to purchasing a solar inverter, it is crucial to evaluate and understand your specific energy requirements.

When it comes to electricity distributions & supply, the role of transformers is essentially crucial. Before electricity reaches our homes from power stations, its overall voltage needs to be reduced in such a way that our electric wires and equipment are able to operate without getting damaged. Electrical gadgets of even the highest quality such as UPS systems from Nantech - one of the leading UPS manufacturers in Chennai can operate smoothly because transformers do their job.
So, the high voltage transformers come into the picture to ensure optimum performance of electricity supply systems and safety of users. Needless to say, the role of transformers is quite vital. Let us learn more about the overall scheme of things.
Essentially, high voltage transformers are electrical equipment with the ability to decrease the voltage phases of electricity. These transformers need to have the highest standards of insulation installed in them to meet the usage requirements of people living in a particular locality. However, even the best high voltage transformers experience breakdowns when the voltage levels surge too much in limited time. Technically, all high voltage transformers operate in a single phase of voltage having core type functionality.
Varieties of High Voltage Transformers
Electromagnetic induction is the general principle based on which all high voltage transformers operate. However, there are three important varieties of transformers, namely:
Various Designs of High Voltage Transformers
To transform voltage as well as current electric levels, transformers use the concept of electromagnetic induction in both coils. They could be set up in either as a single phase or 3 phase. When you start moving towards the bottom of the list of the high current voltage coils, the size as well as costs of a transformer tend to increase. The single phase configurations can be set up for single-phases, dual phases, quad phases as well as ladders or even 5 lead. Three phase configuration on the other hand, are set up for Wye and Delta configurations.
If the high voltage transformers are to be utilised for multiple low voltages and also to avoid short circuits, then they must have multiple primary. When you are looking to buy or design High voltage transformers, there are some crucial factors to consider. These factors include highest ratings for secondary voltage & current, greater output as well as power ratings. These devices can also be built in the form of toroidal transformers. Laminated transformers may also be considered. Toroidal pulse transformers generally have copper wire surrounded around with a cylindrical core to allow the magnetic flux to flow. On the other hand, the laminated transformers have layered cores. They are also referred to as E-I transformers which have been insulated using an insulating dielectric material.
The method of operation of high voltage transformers must be pretty clear from reading the above sections. Various means and methods are used to decrease the voltage of electric currents in the transformers so the electricity becomes safe for use by the components to which it shall go.
The fundamental principles in transformer operation is this– an electrical charge generates a magnetic field and that the magnetic force inside the winding can start producing voltages across the coil. As a result of their close vicinity, the electricity in the primary coil generates a magnetic field causing power output throughout the secondary coil to be much lower in terms of voltage. If the secondary coil has more turns, it generates more voltage and the transformer is referred to as “set-up”. On the other hand, lower number of turns produces lesser voltage and is termed as “step down”.
At its core, high voltage transformers are converters that receive electricity at high voltages. Thereafter, voltages are converted through one level configuration to the other, typically from greater to lesser. The insulating abilities of these power transformers should always be cautiously created to endure these high voltages
High-voltage transformers are also utilised to power plasma generators. Specially designed coils are employed to increase voltages to levels that are sufficient to generate plasma. Wind turbines and other crucial sources of renewable energy make use of these devices to transfer energy to where it is needed. Other application areas for these devices encompass:
Staying Safe When Working With High Voltage Transformers
Since current transformers have the ability to handle high voltages, it is critical that precautionary measures are taken wherever it has to be handled directly, with the goal of preventing accidents.
Takeaway
The significance of using top notch transformers in a distribution system for electricity cannot be overstated. Transformers are an essential component for ensuring good electrical service and network security. High-voltage transformers are used in a wide range of industrial sectors and systems. They seem to be especially helpful for securely managing voltages lesser than or equal to 15,000 volts.
How often have you brought a brand-new home appliance without buying a voltage stabiliser? Probably never. If you live in a country where your electricity supply is plagued with voltage fluctuations, you will need stabilisers to safeguard your appliances. Stabilisers are essential to prevent expensive appliances from permanently damaging by power fluctuations.
A voltage stabiliser will give your appliances a long life and is a long-term investment. Our blog discusses everything you need to know about voltage stabilisers and what to consider when investing in one.
As small and compact as they seem, voltage stabilisers are powerful electrical devices designed to recognise and regulate voltage fluctuations and deliver a consistent voltage output range.
Let’s explain how a stabiliser works without sounding complicated and technical. When your utility voltage is too low, the in-built electronic circuit in your stabiliser senses it, enabling an electromagnetic relay to compensate for the voltage loss and feed the regulated power to the connected equipment. When the incoming voltage is too high, the stabiliser activates another electromagnetic relay to deduct the excess voltage.
What Powers Your Voltage Stabiliser?
Your voltage stabiliser is no less of an engineering marvel. They are built with electronic circuitry that uses electromagnetic relays to change the taps of the in-built autotransformer to generate the desired voltage when the power fluctuates. When the voltage supply falls outside the range, a mechanism switches the transformer tap and brings the supply into the safe range.
There is no dearth of stabilisers in today’s market. Voltage stabilisers are in high demand due to the influx of innovative home appliances into the consumer market. Stabilisers designed with the latest technology can protect your expensive home appliances from voltage fluctuations for a long time. However, there is one contingency: You cannot use the same type of stabiliser for all your appliances. There is no “one-size-fits-all” because different stabilisers are needed for different appliances.
It is important to choose a voltage stabiliser, especially for the appliance to which it will be attached. Stabilisers are classified according to the following:
All appliances are designed to operate on a specific energy limit, and voltage stabilisers are manufactured with these specifications. Based on these criteria, there are different stabilisers available for:
It is not right to pick any stabilisers off the shelf. It is crucial to select the right one, and you need to consider aspects such as:
When you purchase a new refrigerator or air conditioner for your house, your salesman will recommend you to club your purchase with a stabiliser. Here are five technical factors to check when before paying for the voltage stabiliser:
1. Working range
The working range of a stabiliser is the voltage range in which the stabiliser regulates the input voltage and delivers the desired output.
2. Load connection
One of the most important aspects is the nature of the load connected to the stabiliser. Getting the VA (or Volt Ampere) from Watts (W) will require some measurements, but you can approximate the VA size by increasing Watts by 20%.
3. Surge current
You should also consider the surge current that flows through your device when you switch it on.
4. Voltage rating
Every stabiliser has a specification sticker with information about the following:
The standard service voltage for stabilisers manufactured in India is 230 VAC, 50 Hertz.
5. Stabiliser rating
You can calculate the stabiliser rating by multiplying 230 x maximum rated current for all the appliances you want to connect to the device and adding an extra 20-25%. If you intend to add more appliances to it, you need to keep a buffer accordingly.
Next, you should look for certain features to ensure you are buying an upgraded device. A good, modern stabiliser should have the following:
Are you still in a dilemma about investing in stabilisers? Do you think your TV or air conditioner does not require a stabiliser because it has upgraded technology? Well, think again, or you could end up with a severely damaged device.
A good stabiliser will not cost much, and even if it does, it is not an expense, but an investment, because it:
1. Prevents equipment malfunction
All electronic devices come with safe operating limitations, and any non-compliance can have disastrous consequences for your device, from simple malfunctioning to complete operational failure.
2. Enhances appliance longevity
Voltage stabilisers smooth out power from the electric grid by suppressing surges. In the absence of a stabiliser, your appliances are susceptible to sudden spikes and dips in the current supply. A voltage stabiliser will ensure your appliances work for years without any issues.
3. Ensures overall safety
When your expensive equipment is connected to stabilisers, there is a much lesser fire risk due to faulty wires and short circuits. In short, a stabiliser provides round-the-clock protection to electrical appliances, your home, and your family.
Some things are more a necessity than a luxury, and a voltage stabiliser is one of them. Now that you understand the importance of these devices, it is best to buy the appropriate stabilisers for the devices in your home. Nantech Power Systems, Chennai, provides a wide range of affordable voltage stabilisers for various appliances. Give us a call to find the right one for your requirements.
Uninterruptible Power Supply Systems (UPS Systems) perform backup and conditioning roles for the systems they are connected to. They are very important in situations where primary power supplies fail or other power supply problems, such as spikes, brownouts, electrical noise, sags, or surges. UPS systems protect small business applications used for communication, entertainment, or security from electrical surges or sags and prevent business disruption, data loss, or even injuries and fatalities.
In this article, we’ll tell you all about UPS Systems and have you choose the best UPS type suited to your business.
The UPS is a battery backup system that can perform many important functions in a set-up that depends on a primary power supply. Its main role is to act as a secondary power supply that will run long enough to shut systems down properly and back up data sufficiently when an unexpected power outage occurs. The UPS also performs an important surge-protector function to keep devices safe from the harmful effects of abnormal voltages and surges, including reduced performance or lifespan of the device. So it saves the company a world of pain when it prevents data loss and device stress or damage by preventing forced shutdown during an unforeseen power outage.
An acid or lead battery inside the UPS system provides the backup power required when its sensors detect that the main power supply has suddenly shut down. This backup power will not be available for an extended period, but it allows operators to save or back up any critical data and shut the system down gradually or function until the power supply is back on.
UPS Systems are of three main types - the line interactive system, the standby system, and the online system. Other types exist, but they are usually hybrid combinations of two or multiple main UPS system types.
Let’s discuss these system types in more detail:
1. The Line Interactive UPS System
This system serves a dual purpose as a backup power source and a power conditioner. It is the optimum system type if your devices function in an environment with rare power outages but frequent fluctuations. The system can adeptly handle several ranges of fluctuation episodes before switching on its battery power backup. This benefit of handling wide ranges of fluctuations and the circuitry for voltage boosting is a critical one. In fact, wider ranges of accepted fluctuation in the system will give you more overall protection for your devices.
2. The Standby UPS System
The Standby system earned its name from its basic function of acting as a standby when there is a sudden power outage. It performs conditioning for minor surges and usually draws power from the main AC source during normal functioning. The system is also provided with an AC/DC inverter that kicks in when sensors detect trouble in the main power source. But this system has a small transfer time drawback that users should be aware of.
3. The Online UPS System
The online UPS system, also called the double conversion system, performs by isolating the device load from the main power grid. It achieves this by following an AC/DC DC/AC double switch. The online UPS system converts the incoming supply of main power to DC and then back to AC, effectively isolating the load from the rest of the grid.
This switching function is possible because of the rectifier device in the system, which receives incoming power, converts it to DC, and feeds it into the inbuilt battery and onto the connected device through an inverter. This system nullifies the need for power transfer switches. In a power outage, the rectifier drops its connection with the main grid and uses the battery energy to power the connected device until the main power is restored.
Four main factors should determine your choice of UPS systems for your devices. These are discussed at length below:
1. Determine common power problems.
Power blackouts are the most common power problems people are aware of. But when electronic devices and critical equipment are involved, you will need to be aware of the following:
If your business is operating in an area that faces blackouts, brownouts and surges but none of the other power anomalies, a standby UPS system could work well for you. An online UPS system may be required if you face a combination of all the above power problems.
2. Select the right size.
The optimal UPS system for your business will have to be sized correctly in terms of capacity. Depending on how much equipment will need the supported power supply and the combined load or amount of power they will use, you can choose a UPS with a comparable load capacity. You can find information about capacity and load in the corresponding user manuals of your devices and the UPS system you are considering. Manufacturers or other professionals could also help you make the right connections to match device load to UPS capacity.
3. Determine optimum run time.
Runtime is the next important consideration for choosing the right UPS system. Runtime is the amount of performance time your system requires to provide alternate power when there is a power outage or other trouble in the main supply. Calculate how much time you will need to perform a safe system shutdown and data backup, and this can be used as runtime. System load or the amount of power load your system needs to back up has an effect on runtime. A larger load will mean less runtime or battery life, and vice versa.
Think in ranges when determining optimum runtime. Work from the least amount of time you will need to optimise your devices and work up from there. A broader range of runtime will give you more choice in UPS systems.
4. Choosing an appropriate form factor.
There are three main form factors or size and shape of the device housing. These are:
In short, form factor choice is usually determined by where you want to place your system.
Conclusion
UPS systems are not everyday buys. They are high-priced investments that must be carefully considered and matched to your needs. At the same time, they are necessary in most cases and are invaluable for protecting your devices and company data. If you are looking for professional, experienced UPS dealers in Chennai, our Nantech services will be just the right fit for you!
All businesses have one main goal- Providing the best customer experience. This is true even if you want to set up an EV charging station. Wondering what an EV charging station has to do with customer experience? Well, here's a fact: Charging EVs takes time. We are talking about a minimum of thirty minutes to get at least 80% charge.
Longer charging times mean longer dwell times for customers. To make their charging experience worth the time and money, you need to spruce up your charging station with adequate amenities and services.
EV charging is unlike refuelling your car or bike, where you fill it, shut it, and forget it. And let's not forget that even fuel stations nowadays sport coffee shops and mini stores for their customer's benefit. No one's complaining about having a quick cuppa or a packet of chips after filling their gas tanks, are they?
The reason for having amenities in a charging station is more profound with EVs. An EV's charging capacity depends on:
Sometimes, even the weather determines how an EV's battery remains charged. Besides, once a battery is 80% charged, the charging speed slows down to prevent the battery from being damaged. However, an EV with 80% charge is good to go for hundreds of miles.
So, let's say a customer drives into your EV station to charge their car. Their dwell time will range from at least 15 to 60 minutes, even if you have an ultra-modern charging facility. What will your customers do while waiting for their vehicles to charge? Having all the potential services, amenities, and merchandise within their reach will improve their charging experience and give them a reason to return to your station.
This is also a great strategy to improve business and encourage people to opt for EVs.
So, let's check out the various amenities your EV charging station can have.
1. Restrooms
A restroom is the most basic convenience businesses must provide for their customers. Once their vehicles are plugged in, the next thing they may want to do is answer nature's call. A restroom is a must, especially if your station is located on a remote highway or away from the city or town.
2. Lounge area
Having high-volume charging traffic is the key to justifying lounges. From a business perspective, a well-equipped lounge with ample conveniences such as clean bathrooms, WiFi, workstations and a coffee bar could be a valuable money-making factor. Moreover, these lounges would be useful for drivers of ride-sharing services at airports and other high-traffic areas.
3. Food service
Remember that at least 70% of the travellers who stop to charge their EVs wouldn't mind grabbing a quick bite to eat. It would not be a problem for customers to order a sandwich, burger, or burrito for the same amount of time it would take for the car to charge. And let's not forget the number of customers a coffee shop would attract just by having EV charging points in their parking lot.
However, this concept would only make sense if your station has at least a hundred charging stations.
Another ideal scenario that may work for you (especially if you are short-staffed) is to install vending machines. You can also opt for third-party vending machine services for refilling and maintenance.
4. Shops
There's a high possibility for EV owners to make a purchase while refuelling their cars. Think of it- There's no better way to kill time than to browse the aisle of a well-stocked convenience store, grab a few knick-knacks or stock up on the potato chips for kids. This incredible business strategy works both ways: You can install EV charging points at your convenience store or vice versa.
5. Entertainment
Install a wide-screen LED TV and set up a dozen comfy-looking chairs, and you will have a room full of EV owners catching up on the news or watching a cricket match while waiting for their vehicles to charge. A TV will also give weary children some respite from a long day's travel.
6. Air for tyres
Today, almost every fuel pumps have air-filling stations because it has become more of a necessity than a luxury. Besides, most stations offer this amenity completely free of cost. Hence, installing an air-filling station along with the charging outlets only makes sense.
7. Maintenance services
Generally, EVs require very little maintenance. However, you could think about investing in a small maintenance workshop, especially when business picks up and your centre starts attracting more vehicles. You can offer quick or emergency services like:
Other services like car wash or self-service vacuum options can also be considered.
8. WiFi connection
Providing WiFi networks to incoming customers is a fast-catching trend. Not everyone will want to watch TV or spend time at your convenience store.

Have you ever considered the wiring and internal components when buying a voltage stabiliser to safeguard your home appliances? Likely not. Most of us overlook these important details.
In the case of a voltage stabiliser, the winding material is the most important component that plays a major role in how the device works. The winding material comes in two choices- Aluminium and Copper. Now comes the million-dollar question: "Which material is better- Aluminium or Copper?"
This blog analyses the differences and the functionalities of both materials to make it easier to pick the right choice. But first things first...
Most appliances in your home or office function with the solid support rendered by the voltage stabiliser. It is an appliance that keeps the flow of voltage-current stable and protects your devices from voltage fluctuations and erratic power supply.
Let's say there is a sudden, unexpected drop in the incoming voltage. Your stabiliser jumps into action, activating the electromagnetic relays. These relays, in turn, add extra electricity to the secondary winding and compensate for the voltage drop. Similarly, if there is a sudden increase in voltage, less electricity is relayed to the secondary winding to stabilise the output voltage.
So, essentially, the winding material is the "heart of the stabiliser," without which the device cannot work. Industry experts say that copper has the upper hand compared to aluminium, although manufacturers widely use both materials. What makes copper superior to aluminium? Why is it the preferred choice? Let's find the answers in the following discussion.
1. Thermal Connectivity
Copper has the upper hand in thermal conductivity, especially when it comes to reducing the hot-spot temperature rise in transformer windings. However, this superiority is achievable only when both windings are similar in size, geometry, and design.
It is also possible for aluminium to achieve the same thermal conductivity characteristics by making the aluminium coil 66% larger in its cross-sectional area. However, whatever the winding material, stabiliser manufacturers conduct several tests to produce acceptable hot-spot gradients. They:
2. Current distribution
Copper's higher metallurgical properties make it a better distributor of electricity when compared to aluminium. Copper winding enables an even, reliable, and stable current distribution than aluminium winding.
3. Terminations
One problem with aluminium stabilisers is the formation of oxide, which does not enable easy detachment from terminations. Here again, copper reigns supreme because they are soft and easily detachable. This makes copper stabilisers more durable than their aluminium counterparts.
4. Galvanic action
Galvanic action occurs between two electromagnetically different metals in contact to create a conductive path for ions and electrons to move from one metal to another. Galvanic actions sometimes result in complete loss or partial loosening of contacts. In this scenario, aluminium stabilisers lose more material through galvanic action than copper stabilisers.
5. Creep Level
Under extreme loads or high temperatures, aluminium stabilisers are more susceptible to failure than copper stabilisers because the creep rate of aluminium can reach 25 times.
6. Connectivity & Performance
Due to lower energy losses, copper stabilisers perform better and are more efficient than aluminium stabilisers. Moreover, copper is more conductive than aluminium due to oxides, chlorides, and sulfides. Aluminium connections are susceptible to corrosion, so it is more important to clean and protect their joints. Also, the connections between aluminium transformers and copper building wire are not very dependable.
7. Strength and flexibility
Without a doubt, aluminium is a strong and flexible metal. But here again, copper is far superior in both aspects. Therefore, stabilisers with copper winding require fewer inspections and maintenance procedures when compared to those with aluminium winding.
8. Manufacturing expenses
Although copper is expensive, copper stabilisers require less material and cross-sections of the conductor. Therefore, it costs less to manufacture copper stabilisers than an aluminium ones. Furthermore, copper stabilisers are more viable because they require:
These are some of the reasons why stabiliser manufacturers prefer copper over aluminium.
The winner is copper all the way! Aluminium is good, but copper is the best because it has:
Other reasons why copper is highly recommended:
An aluminium wound coil requires approximately 1.8 times as much cross-section to carry the same current as copper. More cross-section means more manufacturing costs.
Compared to copper, aluminium has a potential threat, which is its reaction with oxygen in the air, causing it to overheat and burst into flames.
Transformers with a higher copper content typically have higher energy performance and lower lifecycle costs.
We have stated enough reasons to justify why copper-wounded stabilisers are far better than aluminium-wounded stabilisers. However, in reality, aluminium stabilisers quickly gain acceptance because of the cost advantage.
Yes, copper is expensive, and that is one of the reasons why manufacturers prefer aluminium. However, awareness of copper stabilisers and their benefits will enable consumers to see beyond the price point and make the right choice.

Solar panels are gaining popularity among the masses for their sustainability and eco-friendliness. As efforts to reduce the environmental damage continue to increase, solar panels and other sustainable forms of energy are gaining a wider consumer base as a cheaper and more efficient fuel than coal and other fossil fuels. In this article, we take a closer look at solar panels and ways to use and maintain them efficiently.
Solar panels and solar power gain over other non-sustainable forms of energy in three important ways. They are:
It is now common knowledge that energy consumption methods commonly practised in homes and businesses generate large amounts of hazardous waste. This affects the environment at many levels. The use of solar panels eliminates this pollution by storing and using the sun's energy to power common household appliances like lights and heaters. Here's how the use of solar panels can be beneficial to the environment.
Using solar panels reduces:
Using solar panels can help reduce our dependence on energy sources that produce hazardous chemical wastes like oil sludge and coal ash which increases the presence of metal compounds in the environment to dangerous levels.
It is now commonly known that traditional methods of electricity production have had devastating effects on the environment. Power plants that generate electricity release dangerous toxins like carbon dioxide, nitrogen dioxide, mercury and particulate dust. This has led to phenomena like global warming and climate change, contaminated fisheries, acid rains and smog.
The use of solar panels can reduce our dependence on such toxic power sources. Even limited use of power panels energised by the sun can significantly impact total energy production and consumption.
Water bodies have also suffered tremendously from pollution because of our dependence on coal-based power plants. They release toxins like arsenic, boron, selenium, mercury and cadmium into water bodies, effectively poisoning them. Release of large amounts of warm, low-oxygenated water into water sources has only added to the damage. The adoption of solar energy can reduce our dependence on these dangerous, unsustainable sources of energy, and also give the environment a chance to recover from the damage.
Coal-based power plants raise the need for surface mining, bringing profound environmental challenges to the forefront, even before coal-based energy is produced. The energy produced by solar panels can eliminate the need for coal-based energy, thus cutting down on the impact on the environment.
Solar panels are fundamentally durable and sustainable sources of energy. They can withstand adverse weather conditions. But we can take a few steps to maximise their life and protect them from unnecessary damage. Here are seven simple ways to protect your solar panels:
Periodic cleaning is necessary to maintain the optimal functioning of solar panels. Washing down with a hose pipe needs to be supplemented with a thorough scrubbing with a soft rag or sponge. Experts recommend using the rag or sponge attached to a pole from the ground level.
Falling trees are not the only things that can damage solar cells. Branches, leaves and twigs that fall continuously can scratch the surface of the cells and reduce their efficiency. This will lead to a need to replace the cells, which can be expensive.
The sealants on the solar panels can wear with time. This will affect their functioning since water and dust can seep through the gaps into the PV mechanism and cause short-circuiting. Faded sealants can be repaired, preferably with a silicon-based sealant that is effective and easy to use. Regular inspection will help you identify areas that need repair. Major wear and tear in significant places like the area between the roof and panels will have to be replaced.
Natural disasters and similar occurrences cannot be prevented. But there are measures one can take to control the damage. Many businesses and homeowners install lightning rods to protect solar cells from lightning strikes. Even indirect strikes can cause a power surge that can harm the panels and people.
Installing solar panels requires proper grounding for protection and proper functioning. Anchoring is also an important step in proper solar panel installation. As the name suggests, anchors are tools that hold the solar panels in place, even in the roughest weather. Panels that are mounted in the ground require proper earth-anchors to withstand any weather.
Natural disturbances to the smooth functioning of the solar panels can come in many forms:
It is recommended that you instal mesh wiring and other protective measures to prevent such damage.
Retaining walls are supporting structures made of pre-cast concrete, which can form an impenetrable support against weather and climatic conditions like rains and storms. These can last for decades and work to strengthen the foundation on which the panels rest. They will be a good investment if you live in places that receive large amounts of rainfall or experience other adverse weather conditions.
Solar panels are considered permanent fixtures when installed on the roof. They can be insured against damage due to fire or water and theft or vandalism. Many companies also provide insurance for accidental damage.
There are many advantages to investing in solar energy. It is one of the most beneficial sources of power - it is endlessly sustainable, cost-effective, and energy-efficient. There are long-term benefits to the environment and ultimately to your health and well-being as well.
For all these reasons, it will be wise to invest in solar panels for energy production in your home. For maximum benefit, follow the tips discussed above to enjoy the benefits of solar panels for many years to come.
