Frequently asked questions: 3 kW Solar
Why is 3 kW the most popular residential solar size in India?+
The central government subsidy caps at ₹78,000 for 3 kW. Systems larger than 3 kW do not receive any additional subsidy per kW. Combined with average Indian 3 BHK household consumption (350–450 units/month), 3 kW achieves the maximum financial ROI.
How much does a 3 kW solar system save every year?+
Generating roughly 4,300 units annually at an average grid tariff of ₹8 to ₹10/unit, a 3 kW system saves approximately ₹35,000 to ₹45,000 on electricity bills each year.
