Solar Subsidy Calculator
Estimate rooftop solar subsidy eligibility, likely subsidy amount, and your post-subsidy payable amount for a planned residential solar system in India.
Estimate your subsidy
Enter your proposed solar system size first. Add state, user category, and connection type for a more grounded subsidy planning estimate.
Residential users usually have the clearest rooftop subsidy path. Other categories may have limited or no direct central subsidy support.
Used for simple state-level cost or subsidy overrides if configured in admin.
Enter the rooftop solar size you are considering, in kW.
This keeps the estimate aligned with rooftop use cases that usually seek subsidy support.
How subsidy is estimated
- We start with your proposed rooftop solar size and apply shared installed-cost assumptions to estimate project cost before subsidy.
- We then apply a simple residential subsidy slab model with an eligible capacity cap and any optional state bonus configured in admin.
- Finally, we show likely eligibility, estimated subsidy amount, and the net payable figure so you can compare solar quotes more confidently.

Your rooftop solar subsidy estimate
Use these outputs to compare total cost before subsidy, likely subsidy support, net payable amount, and the planning assumptions behind the estimate.
Likely subsidy status
Waiting for inputs
A directional eligibility signal based on the selected user category, connection type, and size assumptions.
Estimated subsidy amount
Rs 0
Indicative subsidy based on shared slab logic and any configured state bonus.
Estimated system cost before subsidy
Rs 0
Indicative upfront project cost using the shared per-kW assumption.
Estimated net payable after subsidy

This highlights the likely amount left to be funded after the subsidy estimate is applied.
Eligible capacity considered
0 kW
Only the eligible portion of your proposed system size may count toward subsidy estimation.
Indicative cost range
Rs 0 - Rs 0
A planning cost range before site survey, equipment selection, and final vendor quotation.
What this means
This calculator applies a simple residential rooftop subsidy model using shared per-kW slabs, an eligible capacity cap, and indicative installed cost assumptions. Scheme rules, DISCOM processes, and state-specific policies can change over time.

Subsidy estimates are directional only. Final eligibility, approved capacity, payable amount, and disbursal depend on the active government scheme, DISCOM process, application status, rooftop suitability, and official sanction.
