Question 1

How much does a solar system cost in India?

Accepted Answer

The cost of a solar system in India ranges from Rs. 50,000 to Rs. 70,000 per kW before subsidies. After the PM Surya Ghar subsidy, the effective cost for residential systems can be as low as Rs. 35,000-45,000 per kW. For a typical 3 kW residential system, you can expect to pay Rs. 1.5-2.5 lakhs after subsidy.

Question 2

What is the PM Surya Ghar Yojana subsidy?

Accepted Answer

PM Surya Ghar Yojana is a government scheme providing subsidies for residential rooftop solar: Rs. 30,000 for 1 kW, Rs. 60,000 for 2 kW, and Rs. 78,000 for 3 kW and above systems. The subsidy is credited directly to your bank account after installation and net metering approval.

Question 3

How much can I save with solar panels?

Accepted Answer

On average, a 3 kW residential solar system can save Rs. 3,000-5,000 per month on electricity bills. Commercial and industrial installations often see 30-50% reduction in energy costs. The payback period is typically 3-5 years for residential and 2-4 years for commercial systems.

Question 4

How long do solar panels last?

Accepted Answer

Quality solar panels come with a 25-year performance warranty and typically last 30-35 years. They degrade at about 0.5-0.7% per year, meaning after 25 years, they still produce around 85% of their original output. Inverters usually need replacement after 10-15 years.

Question 5

Do solar panels work during monsoon or cloudy days?

Accepted Answer

Yes, solar panels work during cloudy days but at reduced efficiency (typically 25-40% of normal output). During monsoon, you may generate 50-60% less power than sunny months. However, grid-connected systems ensure uninterrupted power supply, and net metering credits from sunny months help offset the difference.

Question 6

What is net metering and how does it work in India?

Accepted Answer

Net metering allows you to export excess solar power to the grid and receive credits on your electricity bill. When your solar panels produce more electricity than you need, the surplus flows to the grid. At night or on cloudy days, you draw power from the grid, and your credits offset the consumption. Most Indian states have favorable net metering policies.
