An on-grid solar system is directly connected to the local electricity grid. When the system generates more power than you use, the excess electricity can be sent back to the grid, often earning credits or payments.
This system offers several benefits — it lowers electricity costs, reduces carbon emissions, and adds value to homes or industrial facilities. Because of its flexibility and cost-effectiveness, the on-grid system is often the preferred choice for industries.
If you’re seeking a reliable, efficient, and eco-friendly energy solution, switching to solar is a smart step toward a sustainable future.
Net Metering System
- A solar on-grid system is connected directly to the main electricity grid.
- It automatically manages power when production is more or less than your energy demand.
- When sunlight is low and the panels can’t generate enough power, electricity is drawn from the national grid.
- When solar production exceeds usage, the extra energy is sent back to the grid.
- The system records this through a net meter, which tracks both imported and exported electricity.
- Users earn solar credits for the excess energy supplied to the grid.
- These credits can be used to offset future electricity bills or can be settled in cash at the end of the billing cycle.
- This arrangement is known as the Net Metering System, promoting efficient energy use and cost savings.
1. Residential Road → Residential Sector
- For any new connection or load expansion exceeding 2 kW, it is mandatory to source at least 3% of the total connected load from solar energy.
- This initiative encourages households to adopt clean energy and reduce pressure on the national grid.
2. Commercial & Industrial (C&I) Sector
- For load connections or expansions below 50 kW, 7% of the total lighting and fan load must be powered by solar energy.
- For connections above 50 kW, the requirement increases to 10% of the lighting and fan load.
- These measures aim to ensure that businesses contribute to the country’s renewable energy goals while reducing operational energy costs.
3. Textile Industry
- Textile industries are required to meet 7% of their lighting and fan load through solar energy.
However, to qualify for net metering, no more than 70% of the total sanctioned load can be covered by solar power. This ensures a balanced integration with the national grid while promoting sustainability.
Frequently Asked Questions
What is an On-Grid Solar System?
An On-Grid Solar System is a solar power setup that is directly connected to the national electricity grid. The system generates electricity from sunlight through solar panels, and any extra power you produce is automatically sent back to the grid — helping you reduce your electricity bill and even earn credits for surplus energy.
How does it work?
During the day, your solar panels generate electricity that powers your home or office. If your solar system produces more electricity than you consume, the excess energy flows back to the grid through a net metering system. At night or on cloudy days, you can draw electricity from the grid as usual.
What are the main benefits of an On-Grid Solar System?
Lower electricity costs – Save money every month through net metering.
No battery required – Works directly with the national grid.
Eco-friendly – 100% clean, renewable energy.
Long lifespan – Durable panels with 20–25 years of performance.
Scalable – Can be expanded easily as your power needs grow.
Is it suitable for both homes and businesses?
Yes! The On-Grid Solar System is perfect for residential, commercial, and industrial properties that already have access to grid electricity. It’s ideal for places with high daytime energy consumption — like offices, factories, and households.
What happens when there’s no sunlight or a power outage?
On-grid systems depend on sunlight and the main grid. During power outages, the system automatically shuts down for safety reasons. However, you can add a hybrid inverter and battery backup if you want uninterrupted power even during blackouts
How much does it cost, and how long does it take to recover the investment?
The cost depends on your energy requirement and system size. Generally, On-Grid Solar Systems recover their cost within 3–4 years, after which you enjoy free or minimal-cost power for decades.
