A solar on-grid system, also known as a grid-tied or grid-connected solar system, is a solar power system that is connected to the public electricity grid. This system allows you to generate electricity using solar panels and directly supply it to the grid or your home. Any excess energy produced can be fed back into the grid, often for credit or compensation through net metering.

The system consists of solar panels that convert sunlight into direct current (DC) electricity. This DC power is then converted into alternating current (AC) electricity by an inverter, making it suitable for use in your home or business. If your solar system produces more electricity than needed, the excess is sent to the grid. When your system doesn’t produce enough power (e.g., at night), you can draw electricity from the grid.

1. Cost Savings: By generating your own electricity, you reduce your dependence on the grid, leading to lower electricity bills.
2. Net Metering: You can earn credits or payments for the excess electricity you supply to the grid.
3. Lower Maintenance: Since there are no batteries, the maintenance required is minimal.
4. Eco-Friendly: Reduces your carbon footprint by using renewable energy.

No, a solar on-grid system does not require batteries. It relies on the grid to balance the electricity supply and demand. When your solar panels generate more electricity than you need, the excess goes to the grid. When they generate less, you draw electricity from the grid. This eliminates the need for costly batteries and simplifies maintenance.

During a power outage, a standard solar on-grid system will shut down automatically. This is a safety feature to prevent the electricity generated by your solar panels from being sent to the grid, which could endanger utility workers repairing the grid. If you want to have power during outages, you’ll need a solar system with battery backup or a hybrid system that combines on-grid and off-grid features.

Yes, the Indian government provides subsidies under MNRE for residential on-grid solar installations. Eligibility may vary by state and system size.

You’ll need approximately 100 square feet of shadow-free space for every 1 kW of solar panel capacity. The panels should ideally face south (in India) and be tilted to get maximum sun exposure.

After site survey and government approval (for net metering), installation usually takes 3 to 7 working days, depending on the system size and complexity.
