Are there any government incentives for solar?
Central Government Subsidy (PM-Surya Ghar)
The subsidy amount is based on the capacity of the solar plant you install:
- 1 kW System: ₹30,000 subsidy.
- 2 kW System: ₹60,000 subsidy.
- 3 kW or Higher:Fixed at ₹78,000, which is the maximum central subsidy available.
- Group Housing Societies (GHS):₹18,000 per kW for common area facilities (up to 500 kW).

Do solar Panels work on cloudy days?
Performance on Cloudy Days
Solar panels typically produce between 10% and 50% of their rated capacity on overcast days, depending on the density of the cloud cover:
Partly Cloudy: Systems often maintain 50% to 80% of their peak output.
Heavy Overcast/Rain: Generation typically drops to 25% to 50% of its normal capacity.
Will Solar panels work during a power outage?
1 Grid-Tied Systems (Most Common)
Behavior: These systems shut down immediately during a blackout.
Why?:This is a mandatory safety feature called anti-islanding protection. It prevents your panels from sending electricity back into the grid, which could electrocute utility workers trying to fix the lines.
Result:Your house will be in the dark, even if it is a perfectly sunny day.
2 Hybrid Systems (Solar + Battery)
Behavior: These systems continue to work by "islanding" your home from the grid.
How it works:A hybrid inverter detects the outage and automatically disconnects from the utility grid. It then reroutes power from your solar panels and battery storage to your home's essential circuits.
Result:You have an uninterrupted power supply for critical appliances like lights, fans, and refrigerators.
3 Off-Grid Systems
Behavior:These are completely independent and are never connected to the utility grid.
