PM Surya Ghar Subsidy Calculator 2026
Estimate the Central Financial Assistance for a residential rooftop solar system. Standard CFA is ₹30,000/kW for the first 2 kW and ₹18,000 for the additional 1 kW, capped at ₹78,000. Special-category rates are higher. The calculator estimates central subsidy, not total installation cost.

Subsidy rules used
Important: This calculator estimates the central subsidy based on the scheme’s published CFA structure. It is not an official government calculator, and the final subsidy depends on the official application, eligible installation, DISCOM process and government verification.
The PM Surya Ghar Subsidy Calculator provides an estimate based on the solar system capacity and consumer category you select.
Before calculating the subsidy, you may also want to understand who can apply under the scheme. Read our PM Surya Ghar Muft Bijli Yojana (2026): Eligibility, Subsidy, Cost & How to Apply guide.

What is PM Surya Ghar Muft Bijli Yojana?
PM Surya Ghar: Muft Bijli Yojana is a Central Government scheme for residential rooftop solar.
The scheme was approved with an outlay of ₹75,021 crore and aims to support rooftop solar installations for one crore households.
The scheme provides Central Financial Assistance for eligible residential rooftop solar systems.
How much subsidy can you get?
For the standard category, the current CFA structure is:
| Solar capacity | Central subsidy |
|---|---|
| 1 kW | ₹30,000 |
| 2 kW | ₹60,000 |
| 3 kW | ₹78,000 |
| Above 3 kW | Maximum ₹78,000 |
The official scheme structure provides ₹30,000 per kW for the first 2 kW and ₹18,000 for the additional 1 kW, with no additional central CFA beyond 3 kW.
Special-category States/UTs
For special-category States/UTs, the CFA rates are higher:
- First 2 kW: ₹33,000/kW
- Additional 1 kW: ₹19,800/kW
- No additional CFA beyond 3 kW
The official MNRE-related documentation lists these special-category rates.
PM Surya Ghar subsidy calculation examples
1 kW solar system
Central CFA:
₹30,000
2 kW solar system
First 2 kW:
₹30,000 × 2
= ₹60,000
3 kW solar system
First 2 kW:
₹60,000
Additional 1 kW:
₹18,000
Total = ₹78,000
5 kW solar system
The system can be larger than 3 kW, but the central CFA remains capped at:
₹78,000
The official scheme documentation states that there is no additional CFA beyond 3 kW.
How much solar capacity might your household need?
The government has also published indicative relationships between monthly electricity consumption and suitable rooftop solar capacity.
| Average monthly consumption | Indicative solar capacity | Subsidy range |
|---|---|---|
| 0–150 units | 1–2 kW | ₹30,000–₹60,000 |
| 150–300 units | 2–3 kW | ₹60,000–₹78,000 |
| Above 300 units | Above 3 kW | ₹78,000 |
These are indicative capacity recommendations; actual system sizing depends on the household and installation circumstances.
Who can use the PM Surya Ghar subsidy?
PM Surya Ghar is intended for residential consumers with a grid-connected electricity connection from the local DISCOM.
The official information says residential consumers with a grid-connected connection can apply through the National Portal.
The rooftop solar system can be installed on eligible residential premises, subject to the scheme and DISCOM requirements.
Does a 5 kW solar system get more than ₹78,000 subsidy?
No, not under the standard central CFA structure.
The central subsidy is capped at the equivalent of 3 kW.
Therefore:
3 kW = ₹78,000
4 kW = ₹78,000
5 kW = ₹78,000
The additional solar capacity may still be useful, but it does not attract additional central CFA under this structure.
Does the calculator show the total cost of solar?
No.
This calculator estimates the government’s central subsidy, not the final amount you will pay for your solar installation.
Your actual cost can depend on:
- Solar panel selection
- Inverter
- Mounting structure
- Installation
- Wiring
- Metering
- Roof conditions
- DISCOM requirements
- Vendor pricing
- State-level support, where applicable
So you should not subtract the calculator’s subsidy from an assumed solar price and treat the result as a guaranteed final cost.
For that, we should create a separate:

later.

How the PM Surya Ghar Subsidy Calculator Works
Our calculator uses the published Central Financial Assistance structure.
For a standard-category residential system:
First 2 kW: ₹30,000/kW
Additional 1 kW: ₹18,000/kW
Maximum central CFA: ₹78,000
For eligible special-category States/UTs, the calculator uses the higher published CFA rates.
The calculator does not calculate:
- Vendor quotation
- Electricity bill savings
- Payback period
- State subsidy
- Net metering income
- Loan EMI
Those can become separate Benefitomics tools.

3 kW → ₹78,000
Above 3 kW → maximum central CFA ₹78,000
Use the calculator above for a quick estimate, then verify the applicable rules and application process on the official PM Surya Ghar National Portal.
