Find out if rooftop solar actually pays off for your home.

RoofToGrid takes your electricity bill and roof details, then shows two or three system sizes with units generated, subsidy, yearly savings and payback. Then it helps you compare installer quotes on equal terms and track the project all the way to net metering.

Rough numbers in 30 seconds

Nothing is saved and no account is needed. Create one later if you want to keep the results.

The units (kWh) line on your electricity bill, averaged over a year.

Divide your bill amount by the units if you are not sure.

RCC slab. Needs a raised structure, about 100 sqft per kWp.

Only the shade-free part you are happy to cover, leaving walkways.

South-facing roofs generate the most in India.

Open roof, sun all day.

How it works

  1. 1

    Tell us what you spend

    Your monthly units and tariff from any recent bill. No login, no sales call.

  2. 2

    See honest options

    Two or three system sizes with generation, subsidy, savings and payback — plus every assumption we used.

  3. 3

    Compare real quotes

    Enter what installers quoted. We normalise price per kWp, equipment tier, warranties and financing.

  4. 4

    Track it to the grid

    Survey, DISCOM approval, installation, net metering, subsidy — with documents attached to each step.

Built for people, not for a sales funnel

We show the maths

Specific yield, area per kWp, shading derate, cost bands, subsidy rules and escalation are all disclosed on every estimate screen.

Cheapest does not win by default

A price below the realistic floor is capped in scoring and flagged, because it usually means something is missing from the scope.
