How Much Money Can You Actually Save With Rooftop Solar?
By CIVOLT Team 8 June 2025 8 min
The Solar Savings Formula
Solar savings = (Units generated by solar) × (Your electricity tariff). Simple. Now let’s make it concrete.
A 3 kW System Generates...
On average, 1 kW of solar produces 4–5 units/day in India. So a 3 kW system generates about 12–15 units per day, or 360–450 units per month. If your tariff is ₹8/unit, that’s ₹2,880–₹3,600 monthly savings.
Where Do the Savings Really Add Up?
Over 25 years (panel warranty), a 3 kW system generates 1,00,000+ units of electricity. At current tariffs, that’s ₹8–12 lakhs saved. With rising electricity prices (typically 5–8% per year), real savings are even higher.
