Common questions
How many kW of solar do I need in Gujarat?
1 kW makes about 1,500 units a year in Gujarat. A home using 300 units a month (3,600 a year) needs about 2 kW. You can install up to your sanctioned load.
How long does rooftop solar take to pay back in Gujarat?
Usually 2.5 to 5 years after the subsidy. For example, 2 kW on a UGVCL home using 300 units a month costs about ₹50,000 after subsidy and pays back in about 2.2 years.
Why are these savings different from other calculators?
Most calculators multiply units by one flat rate. This one works out your actual bill, slab by slab with all charges, before and after solar.
