A 4 kW rooftop solar system in Indore generates about 16 units a day, 486 units a month and 5,836 units a year. It uses about 8 panels of 545 W and needs roughly 360 sq ft of shadow-free roof. It qualifies for ₹78,000 PM Surya Ghar subsidy, bringing a typical price of ₹2.32 lakh–₹2.72 lakh down to about ₹1.54 lakh–₹1.94 lakh. For a property using 400–520 units a month, it saves around ₹3,529 a month and pays back in about 3.9 years.

## FAQ

With 545 W modules, a 4 kW system uses eight panels (4.36 kWp). With older 440 W modules it would need ten. Fewer, larger modules mean less roof space and fewer connections.
