On-Grid Solar Power Plant in Chennai

ON-GRID SOLAR SYSTEM IN CHENNAI

Creative Energy Saving Solutions
An on-grid solar power plant is the most popular and fastest-payback way to go solar in Chennai. Your rooftop panels generate electricity during the day, your building uses it directly, and any surplus is exported to the TANGEDCO grid through a net meter, crediting you against future grid consumption. The grid acts as your backup, so no batteries are required, keeping the system affordable and low-maintenance. As a TANGEDCO-empanelled installer and a registered PM Surya Ghar vendor, Nantech designs, installs, and commissions on-grid solar systems for homes, offices, and industries across Chennai — managing subsidy registration and net-metering paperwork from start to finish.

ON Grid Solar Panel

How an On-Grid Solar System Works

  • Rooftop solar panels convert sunlight into DC electricity.
  • A grid-tied solar inverter converts DC into 230/415V AC for your home or business to use immediately.
  • Surplus power you do not consume is exported to the TANGEDCO grid through a bi-directional net meter.
  • When solar output is low or absent, you draw from the grid, and your bill is calculated on net units — the difference between units consumed and units exported.
  • No battery is needed. Under TNEB norms, batteries are not permitted on on-grid systems, and the grid serves as your virtual storage.

On-Grid Solar Power Plant for Homes in Chennai

Chennai homeowners installing an on-grid rooftop system cut their monthly electricity bill through a combination of direct self-consumption and net metering credits. System capacity typically falls between 1 kW and 5 kW, depending on roof space and monthly usage. A 3 kW system generates roughly 360 to 420 units a month in Chennai conditions. Residential installations qualify for the PM Surya Ghar: Muft Bijli Yojana subsidy of up to ₹78,000, which Nantech registers and claims on your behalf as a PM Surya Ghar empanelled vendor. Surplus generation during the day is credited against evening consumption through net metering, bringing your effective bill close to zero. Most homeowners recover their investment within 3 to 5 years, after which the system produces electricity at no recurring cost for 20-plus years.

On-Grid Solar Power Plant for Commercial & Industrial Use in Chennai

For offices, showrooms, schools, hospitals, warehouses, and factories, an on-grid solar power plant cuts one of the largest fixed operating costs: the monthly electricity bill. Commercial and industrial systems typically run from 10 kW to several hundred kilowatts on three-phase supply, sized to match daytime load so the majority of generation is self-consumed rather than exported. Beyond direct bill savings, businesses can claim accelerated depreciation on the capital cost under the Income Tax Act, improving the after-tax return on the investment. Nantech manages the complete EPC scope: structural assessment, panel and inverter selection, cabling, TANGEDCO net-metering liaison, commissioning, and ongoing maintenance. Your operations team stays focused on core business throughout.
