What papers needed for solar installation?

You will need your Aadhaar Card, PAN Card, property ownership proof (registry or tax receipt), and a copy of your latest electricity bill. A cancelled cheque is also required to ensure your government subsidy is credited directly to your bank account.

How do you evaluate the cost of solar repair?

Repair costs are determined by the system capacity, the quality of the inverter, and the physical accessibility of your rooftop. We also check if the faulty components are still under their 25-year performance warranty to minimize your out-of-pocket expenses.

What is the per square-feet cost of panel installation?

Solar pricing is calculated per kilowatt (kW), averaging between ₹40,000 to ₹70,000 per kW depending on the technology and subsidies. For every 1 kW of solar capacity installed, you will need approximately 80 to 100 square feet of shadow-free rooftop space.

When should we check the battery connections?

You should perform a visual check for corrosion or loose wires every 3 months to ensure safety and efficiency. Additionally, we recommend a professional annual maintenance visit to deep-clean the terminals and verify the overall health of your storage system.
