On-Grid Solar Panels – The Ultimate Guide

A recent project Mahindra world City is going to be Chennai’s first place, based on environment-friendly principles. It is based on Zero Waste to Landfill Certification which means it is diverting industry waste away from landfills. This leads to a decrease of 115 tonnes of CO2 emissions every month. There are many other ways to minimize environmental damage.This includes investments on more solar, hydro and wind power.

When it comes to Solar power systems, they are divided into three types. On-Grid, Off-Grid, and Hybrid Systems. Nantech has got you covered for in-detailed information about On-Grid Solar System.
On-grid solar power is a system where the generation system is connected directly to the utility grid. The electricity produced through solar systems is routed to the primary utility grid from where the electricity is run through a house and further used for appliances.

These are also known as a grid-tie or grid-feed solar system. On-Grid solar systems are one of the most widely used solar power systems. With new technological advancements, people have started to rely on solar systems, and On-Grid being the most in-demand.

Benefits of On-Grid System

  • First and foremost, the process is easy to install, maintain, and is hassle-free.
  • On-Grid systems are cost-effective.
  • Business owners and residential users can earn side income for the energy generated by the system.
  • Private, Industrial, and Commercial avail 'Accelerated Depreciation Benefit' by setting up a solar PV rooftop system. The benefit is up to 80% in a year.
  • At the rate of 80%, the project's fundamental value can be covered within four years.

Working of the system
The system works in two ways.

  • The supply of electricity can flow from the utility grid to users home and
  • The flow of electricity from the user's home to the utility grid.

These features make the On-Grid system highly useful and affordable. The solar panels installed on the user's home are tied to the Grid. The panels convert sunlight into direct electricity, also known as Direct Current DC). This current is then stored in a solar inverter. The Solar Inverters then convert Direct Current to an Alternating Current. Alternating Current (AC) makes the power accessible and ready to use for electrical items. The electricity is routed to the utility grid, where it is supplied for day to day use.

The grid tier inverted additionally regulated the amount of voltage of electricity used for the household requirements since all the collected power is mostly much more than household usage, needs, and is usually higher than it can handle. One of the essential features is the net meter. It is a device that records and measures the energy supplied to the Grid and the energy consumed.

At the end of every month, an outstanding is recorded, and a bill is provided for the electricity consumed. A solar meter is also used to measure the power generated. The converted energy is stored and then used by homes through the main electricity distribution panel. Battery Backup is not a requirement.

The Difference From Other Available Solar Panel Systems

  • The difference from other available solar panel systems
  • On-Grid is a cost-effective and more straightforward system to install as compared to Off-Grid and Hybrid Systems.
  • Such systems mostly pay for themselves by offsetting the bills in a few years.

Solar power systems are the future of clean, reliable, and renewable power solutions. Setting up a Solar System is valuable for the environment and humanity themselves. Thus, moving forward towards the future with Solar energy is one of the decisions for us.

Off-grid Solar Plants – ON!

With the continually increasing concerns of global warming, there has been a lot of awareness about using clean energy. Solar energy is one such form of renewable, affordable, and inexhaustible energy that we can extract from nature and, in a way, for nature. However, setting up a whole new solar energy system with many options available can be baffling. Opting for solar energy set up requires a fixed commitment and long-term investment. Therefore, it's necessary to do little homework before choosing the solar plant you wish to install. Solar plants are of two types an on-grid solar plant and an off-grid solar plant. An on-grid solar plant generates electricity and is directly connected to the utility power grid.

On the other hand, the off-grid solar grid does not work in conjunction with the utility grid. Instead, they are connected to batteries, which store the power generated by them. Chennai, being a coastal region, often suffers from gloomy and cloudy days. If an on-grid solar panel is the only source of electricity, there could be times when the consumers will have to suffer from power cuts making an already gloomy day gloomier.

When it comes to such rainy, cyclone-prone areas, using an on-grid solar plant is not an extremely reliable option. To curb this problem, Nantech Power Systems Pvt. Ltd, a company based in Chennai, has got you covered. Having expertise in manufacturing power equipment, this company is like a ray of light to fill your ill-lit days with dazzle and sparkle.

Why Choose Off-grid Solar Plants?

Off-grid solar plants work independently of the grid. They have the following components :

  • A bunch of solar panels
  • Grid box
  • Charge controller
  • A battery
  • An inverter
  • A mounting structure

Balance of Systems

The solar panels absorb solar energy, and the excess energy is stored in the batteries. This stored energy from a previously sunny day can be used when the sun has set or during cloudy days when there is no sun at all. These are self-sufficient power providers in areas where power grids remain unavailable, like in rural and remote areas, where they can provide electricity for a long time or in areas where there are frequent power cuts. Another advantage of an off-grid solar plant is that any mishaps like grid failures or shutting down of grids during stormy weathers do not prevent them from supplying energy since they are independent of the utility grids. Therefore, they are autonomous, unstoppable, and infallible. An additional advantage of using the off-grid solar plant is that you don't have to pay any electricity bill if you are using only one energy source that is of your solar plant.

One disadvantage of the off-grid solar plant is that if there are abnormally dark days in a row, the energy stored in the battery may get exhausted, limiting its use. Another disadvantage is that they are costlier to install. However, one should note that the number of benefits an off-grid solar plant has overridden the costs of installing it. Thus, by choosing it, you are self-sufficient and fulfilling your duty as a responsible inhabitant of the planet.

Detailed Guide On Solar Inverters

Solar Power is the conversion of energy from sunlight to electricity. It is one of the essential sources of renewable energy. It uses radiant light and heat from the sun that is harnessed using technology devices such as solar heating and cooling systems, solar thermal, photovoltaics, concentrating solar power, and converts it into electricity. Solar power is one of the cleanest and reliable forms of renewable energy. The devices used to collect the energy are explained in simple terms below.

Photovoltaics

This is a process of converting light into electricity using semiconductors that exhibit the photovoltaic effect. This effect is used commercially for electricity generation and as photosensors.

Concentrating Solar Power

These generate power by using mirrors or lenses to gather the sun's energy onto a receiver and further drive them to traditional steam turbines or engines to create electricity.

Solar Heating And Cooling Systems

Collect thermal energy from the sun to provide hot water, air conditioning, pool heating for resident or commercial usage.

Solar Inverters are a type of electrical converter which converts direct current (DC) output of a photovoltaic panel into a utility frequency alternating current (AC) that can be used for electrical grids, which can be used by local, private networks. Solar Inverters use MPPT (Maximum Power Point Tracking) to get to the maximum possible power from the photovoltaic array. The purpose of MPPT is to sample the cells' output and determine a resistance/load to obtain maximum capacity. Inverters are also referred to as the brains of the entire solar power system. One of the components includes the battery storage system. Stored batteries can be used in the times when the sun goes down during evening and night time.

Solar Inverters are divided into three different types.

  • String Inverter
  • Micro-Inverter
  • Power/ Central Inverter

Stay tuned till the end for some detailed guidance on solar inverters and their types on Nantech.

String Inverter
A string inverter is one of the popular devices used among households. It works well with All Home appliances. It converts Direct Current from solar panels to Alternating current electricity/power. Multiple strings are connected to produce electricity.
String Inverters are also known as Sine Wave Inverters. These can be paired with power optimizers.

Solar Micro Inverter
Solar Inverters used to operate with a single PhotoVoltaic model is known as Solar micro-inverters. These micro converters convert Direct Current(DC) output to alternating currents(AC). It is used for parallel connection of various units (multiple, Independent) because of its design. Micro Inverters are small in size and are plug-in and play a kind of device. These are connected in parallel to each other and then to grids while producing grid-matching Alternate Current(AC) directly at each solar panel bank.

Central Inverter
Just as the name suggests, Central Inverters are connected to form a standard combined inverter that converts the power to an Alternating current (AC). These are usually bigger and than String Converters. Thus, they are only suitable for covering large areas and not for primary household usage. Central Inverter can handle up to 500KW per enclosure.

Solar Inverter gives the benefit of using solar energy without hefty bills of electricity from our power supply. Solar Energy is the most acceptable renewable energy solution for this world full of electronic devices that needs to be charged before use. Thus, using electricity from solar panels and solar inverters might be the best renewable solution one can ever think of.

Fun Facts About Solar Energy And Inverters

Let's start with the fact that Solar inverters are among the most efficient machines built by man, giving up to 97% efficiency in the best inverter and under ideal weather conditions. When we say efficiency we mean, the solar inverter's capacity to convert all the energy it receives from the sunlight into the alternating current it supplies to the devices it is connected to. The amount lost is mainly due to converting the direct current received from the solar panel into the alternating current supplied.

The solar inverter can be referred to as the system's brain as it has 'Maximum power point tracking ability,' which is a feature of genius. It is basically a sensory system that can detect when the battery is connected. The inverter itself is full storage capacity and then breaks the circuit stopping any more from the photovoltaic solar panel. This is an essential protective feature of the solar inverter because it helps prevent an acute decrease in efficiency and protects from any physical mishap.

Grid-connected solar inverters are large scale solar systems where All the panels supply DC to the grid where the main inverter structure would convert all the DC into AC and supply residential and office buildings. Though a little pricey to install, this system will give huge returns in the long term due to its high efficiency and eco-friendly nature. These solar power plants can last for more than 40 years, after which some machinery might need to be replaced. This becomes important when you know that 'One hour of total sunlight hitting the earth is equivalent to one year's worth of energy for the planet.' It is the cheapest energy source as there are no costs to obtain the raw material. For example, you need coal mines to dig up coal.

Many people are under the impression that Solar energy is not a viable source because it is weather dependent, i.e., it will be useless on cloudy days or winter. As a matter of fact, 'Solar energy does not need direct sunlight but only the warm temperature generated by sunlight.' You do not particularly feel cold on cloudy days, you can take cloudy days in the summer as well, but the solar inverter will work just as well.

For you enthusiastic and nature-loving homeowners, here are a few facts helping the cause of solar energy:

  • According to surveys done in the USA, most homeowners have found positive returns on investment within 10 years of installation.
  • Solar panels are fast and easy to set up.
  • In 30 years, your home's typical isolated solar system can reduce CO2 levels by 100 tons.
  • The average solar panel has a 25- year warranty, and the attached solar inverter has at least 2 years of warranty.
  • Solar energy is cheaper than fossil fuels.

So, what are you waiting for? Go ahead and buy a solar inverter to save both your money and the environment!
