How This Solar Calculator Works
This calculator estimates your ideal rooftop solar system size using your average monthly electricity bill, your state's tariff and sunlight data, and your roof details. It then calculates your government subsidy under the PM Surya Ghar Muft Bijli Yojana, your estimated project cost, and your payback period — all before you ever speak to a salesperson.
What Is the PM Surya Ghar Muft Bijli Yojana Subsidy in 2026?
The PM Surya Ghar Muft Bijli Yojana is the Government of India's flagship rooftop solar subsidy scheme, launched in February 2024 under the Ministry of New and Renewable Energy (MNRE). As of 2026, the subsidy structure is:
- ₹30,000 per kW for the first 2 kW of system capacity
- ₹18,000 per kW for the 3rd kW of capacity
- Maximum subsidy capped at ₹78,000, regardless of system size beyond 3 kW
- Special category states (Northeast & hill states) may be eligible for higher slabs, up to ₹1,17,000
The subsidy is paid as a Direct Benefit Transfer (DBT) straight to your Aadhaar-linked bank account, typically within 30–45 days of installation and net-metering by your DISCOM.
Why Use Our Solar Calculator Instead of Guessing?
- Accurate to your state: Tariff rates and sunlight hours vary significantly across India.
- Subsidy already calculated: Your exact eligible PM Surya Ghar subsidy is shown automatically.
- Real payback period: See exactly how many years until your system pays for itself.
- One free survey request, no repeated forms: Your calculator answers carry forward into your survey request automatically.

Frequently Asked Questions
How accurate is this solar calculator?
This calculator provides a reliable estimate based on your stated electricity bill, your state's average tariff and solar irradiance, your roof details, and current 2026 system costs and subsidy rules. For an exact quote, a physical site survey is recommended.
Is the PM Surya Ghar subsidy available for everyone?
The subsidy is available to residential consumers with a sanctioned electricity load of 10 kW or below, who install ALMM-listed solar equipment through net metering with their local DISCOM.
How long does it take to receive the subsidy after installation?
Once your system is installed and net-metered by your DISCOM, the subsidy is typically credited to your Aadhaar-linked bank account within 30 to 45 days via Direct Benefit Transfer (DBT).
What is a good payback period for a solar system in India?
Most residential solar systems in India pay for themselves within 4 to 6 years after accounting for the subsidy, with the system continuing to generate savings for 20+ more years under a typical 25-year performance warranty.
Can I install solar if I live in an apartment or housing society?
Yes, if you have dedicated rooftop access and your own DISCOM meter, you can apply individually. Group Housing Societies can also apply separately for common-area solar at ₹18,000 per kW, capped at 500 kW for the society.
Does this calculator account for battery storage?
No — this calculator estimates a standard grid-connected (on-grid/net-metered) system without battery backup. Battery storage is not covered under the PM Surya Ghar subsidy and can be quoted separately during your site survey.
What happens after I submit the survey request?
You'll see a thank-you confirmation on screen. Our team will reach out within 24 hours to schedule a free, no-obligation site visit and confirm an exact quote.
