How Much Electricity Does 3kW Generate?
In Uttar Pradesh, a properly installed 3kW system can generate around 330 to 420 units per month on average. Summer generation is usually stronger, while monsoon and foggy winter days can reduce output.
Roof Space Needed
A 3kW system generally needs 240 to 300 sq ft of shadow-free roof. If your roof has water tanks, nearby walls, trees, or dish antennas, the installer should do a shadow check before finalizing layout.
Subsidy and Net Metering
For residential consumers, subsidy is processed through the national rooftop solar portal. Net metering is also important because it allows unused daytime solar units to be adjusted against grid import.
Who Should Install 3kW?
- Monthly bill between Rs. 2,000 and Rs. 4,500.
- 2-4 BHK house with daytime usage.
- Roof space of at least 250 sq ft.
- Owner wants subsidy and lower long-term electricity bills.
