An on-grid solar system is the most popular solar solution for Chennai homes today. With reliable TANGEDCO electricity supply across most of the city, an ongrid solar system allows homeowners to generate their own power during the day, use it directly for all household needs, and export any surplus to the TANGEDCO grid — earning bill credits through net metering every month.
SKS Synergies has installed on-grid solar systems across Thiruvanmiyur, Adyar, Velachery, Sholinganallur, Kolathur, Ambattur, and all major areas of Chennai. If your home has a reasonably stable grid supply and you want maximum savings on your electricity bill, an ongrid solar system Chennai home is the right choice for you.

Ongrid Solar System for Chennai Homes
An ongrid solar system Chennai home works by connecting your rooftop solar panels directly to the TANGEDCO electricity grid through a bi-directional net meter. During daylight hours, your solar panels generate electricity that powers your home appliances first. Any excess electricity — beyond what your home is consuming at that moment — is automatically exported to the grid.
At night or on cloudy days when your solar generation is insufficient, your home draws power from the TANGEDCO grid as normal. Your monthly TANGEDCO bill is then calculated on net units — the difference between what you imported from the grid and what you exported from your solar panels. For most Chennai homes, this results in an electricity bill reduction of 70% to 90%.
The on grid solar system Chennai is ideal for homes in areas with fewer than 2 to 3 hours of daily power cuts — which includes most of Chennai city, Adyar, Mylapore, Nungambakkam, Anna Nagar, Velachery, and Sholinganallur.
How an Ongrid Solar System Works — Step by Step
Understanding how your ongrid solar system generates savings helps you make the most of your investment. Here is a simple breakdown:
Daytime — Solar Generation Your solar panels generate DC electricity from sunlight. The solar inverter converts this into AC electricity compatible with all home appliances. Your home uses this solar power first — for lights, fans, refrigerator, air conditioner, and all other appliances running during the day.
Surplus Export When your solar panels generate more electricity than your home is consuming — for example, during mid-morning when the sun is strong but your appliances are minimal — the surplus is automatically exported to the TANGEDCO grid through the net meter. TANGEDCO records this export.
Nighttime — Grid Import After sunset, your home draws power from the TANGEDCO grid as usual. The net meter records this import.
Monthly Bill Calculation Your TANGEDCO bill is calculated on Net Units = Import minus Export. If your export equals or exceeds your import in a month, your electricity bill can effectively be zero.
Solar Power for Home Chennai — On-Grid Benefits
Choosing an on-grid solar system for solar power for home Chennai delivers several clear advantages over other system types:
Maximum Savings — No battery means no energy loss in storage. All solar power goes directly to your home or the grid — maximising the financial return on your investment.
Lower Upfront Cost — On-grid systems are significantly more affordable than off-grid or hybrid systems because they do not include battery storage. This means a faster payback period and better overall return.
25-Year System Life — Solar panels carry a 25-year performance warranty. With no battery to replace, your on-grid system runs for the full 25 years with minimal maintenance.
Government Subsidy Eligible — On-grid systems qualify for the full central government subsidy of up to ₹78,000 under PM Surya Ghar Muft Bijli Yojana.
TANGEDCO Net Metering — Every unit you export earns you a credit against future import — giving you the benefit of the grid as free storage during the day and free backup at night.
Is an On-Grid Solar System Right for Your Chennai Home?
An on-grid solar system is right for you if:
Your area has reliable TANGEDCO supply with fewer than 2 to 3 hours of power cuts per day. You want the lowest upfront investment with the highest monthly savings. Your primary goal is reducing your electricity bill rather than achieving 24/7 power independence. You live in Chennai city, Adyar, Velachery, Sholinganallur, Mylapore, Anna Nagar, Kolathur, Nungambakkam, Porur, or any well-supplied urban area.
If your area experiences frequent power cuts — more than 3 to 4 hours per day — an off-grid or hybrid solar system with battery backup would be a better fit. SKS Synergies will assess your local power supply situation and recommend the ideal system type during your free home consultation.
