What decides solar cost?
Solar pricing depends on system size, roof type, installation complexity, equipment quality, inverter type, local approvals, and whether subsidy is applicable.
That is why two homes with the same monthly bill may still receive different solar recommendations.
Typical cost thinking for homeowners
Most people start by asking for a price per kW. That is useful as a benchmark, but not enough to make a decision.
A better way is to first estimate the right system size for your home, then look at projected savings and payback.

What this means
This sample gives you a realistic benchmark before checking your own home
Use this as a decision reference, not a fixed quote. Your actual solar plan can use your own electricity bill, home location, and rooftop context to generate a more accurate result.
What you should calculate before buying
Before speaking to installers, you should know your monthly electricity bill, approximate roof space, shadow conditions, current sanctioned load, and whether you want bill reduction only or backup as well.
That gives you a much stronger starting point than only asking for a quote.
Common questions
How do I know the right solar size for my home?
The right size usually depends on your electricity usage, roof space, sanctioned load, and your savings goal. A personalized estimate works better than a generic chart.
Does subsidy reduce total project cost?
For eligible residential rooftop installations, subsidy can reduce effective cost, but final eligibility and process depend on the official programme and your DISCOM workflow.
Should I compare price only?
No. Price matters, but equipment quality, generation estimate, after-sales support, installer credibility, and design suitability matter just as much.
