Rooftop solar is one of the few home upgrades that pays for itself through direct, measurable bill savings. Here's how it actually works and how to make sure your system is sized to deliver the savings you expect.
During daylight hours, your solar panels generate electricity that's consumed directly by your home first, before any surplus is exported to the grid. This means your grid consumption — and the bill tied to it — drops immediately once the system is commissioned. Any exported surplus is credited against your night-time consumption through net metering, extending the savings beyond just daytime hours.
The biggest factor in how much you save is whether your system is sized correctly for your actual consumption, not a generic package. A system that's too small won't offset enough of your bill; one that's oversized for your roof or budget doesn't pay back faster — it just costs more upfront for marginal additional benefit once you're already covering most of your daytime load.
| Monthly Bill | Typical Recommended Size |
|---|---|
| ₹1,000-1,800 | 1-2 kW |
| ₹1,800-3,000 | 3 kW |
| ₹3,000-5,000 | 5 kW |
| ₹6,000+ | 8-10 kW |
Up to ₹1,08,000 Government Subsidy Available — as applicable under current Central + State benefits for eligible residential rooftop solar installations in Uttar Pradesh, subject to guidelines and approvals.
Because subsidy reduces your upfront cost without reducing your savings, it directly shortens your payback period — often bringing a 4-6 year payback down further for eligible households.
