PM Surya Ghar Subsidy 2026: 1kW, 2kW, 3kW Amount and Calculation Rules

PM Surya Ghar Central Subsidy Rates in 2026

The residential CFA structure divides a household system into capacity slabs. The first 2 kW receives the higher per-kW assistance. Only the next 1 kW—from above 2 kW up to 3 kW—receives the lower rate. Capacity beyond 3 kW receives no additional household CFA.

Simple Formula for Calculating Household CFA

“Part thereof” means fractional eligible capacity can be calculated proportionately. For example, a 1.5 kW system is not automatically rounded to 1 kW or 2 kW. It is calculated as 1.5 × ₹30,000, subject to actual installed and approved module capacity.

Worked Subsidy Calculations

1. Example: 1.2 kW household system
   Entire capacity falls within the first 2 kW slab.
   1.2 × ₹30,000 = ₹36,000 standard CFA.
2. Example: 1.5 kW household system
   1.5 × ₹30,000 = ₹45,000 standard CFA. This is also the fractional example used in the official guidelines.
3. Example: 2.25 kW household system
   First 2 kW: 2 × ₹30,000 = ₹60,000.
   Remaining 0.25 kW: 0.25 × ₹18,000 = ₹4,500.
   Total = ₹64,500 standard CFA.
4. Example: 2.5 kW household system
   First 2 kW: ₹60,000.
   Remaining 0.5 kW: ₹9,000.
   Total = ₹69,000 standard CFA.
5. Example: 2.8 kW household system
   First 2 kW: ₹60,000.
   Remaining 0.8 kW: 0.8 × ₹18,000 = ₹14,400.
   Total = ₹74,400 standard CFA.
6. Example: 6 kW household system
   First 2 kW: ₹60,000.
   Next 1 kW: ₹18,000.
   Remaining 3 kW: no additional household CFA.
   Total = ₹78,000 standard CFA.

The amount activated for payment is based on the actual eligible installed capacity verified through the portal and DISCOM process. A quotation for 3 kW does not secure ₹78,000 when the approved installation is smaller or non-compliant.

Higher Subsidy for Special-Category States and Union Territories

The official CFA guidelines prescribe higher benchmark and assistance rates for the following areas:

• Uttarakhand
• Himachal Pradesh
• Jammu and Kashmir
• Ladakh
• North-Eastern States, including Sikkim
• Andaman and Nicobar Islands
• Lakshadweep

The rate follows the location and application category of the eligible residential installation. It is not obtained merely because the consumer’s permanent address or identity document belongs to a special-category State.

Subsidy Amount Is Not the Same as the Solar-System Price

The official CFA rates are derived from benchmark costs, but consumers and registered vendors mutually decide the actual system design, component quality, site work and commercial terms. The National Portal does not create one compulsory retail price for every 2 kW or 3 kW system.

Why Module DC Capacity—Not Inverter Size—Controls the CFA

The guidelines state that subsidy is calculated using the rated DC capacity of the solar-module system. A vendor cannot increase the claim by pairing fewer modules with a larger inverter, and a smaller inverter does not automatically reduce the declared module capacity when the technical design remains compliant.

Do Batteries, Solar Trackers or Hybrid Equipment Receive Extra Subsidy?

A rooftop installation may include battery storage, a solar tracker, a small-wind hybrid or another additional technology component. However, the residential CFA calculation continues to use the capacity of the installed eligible solar modules. Extra equipment cost does not create extra central subsidy.

A grid-connected behind-the-meter or battery-hybrid system can also depend on approval under the relevant State Electricity Regulatory Commission framework. Completely off-grid installations are not eligible for the residential CFA covered here.

Subsidy for Expanding an Existing Rooftop-Solar System

A household that earlier received MNRE rooftop-solar CFA may be eligible for additional assistance only for the remaining eligible capacity up to an overall plant size of 3 kW. The earlier capacity and subsidy history must be considered.

Official-Type Expansion Example

Suppose a household previously installed 1 kW and received subsidy, then expands the total system to 4 kW. The new claim does not cover all additional 3 kW. Only the balance capacity needed to reach the 3 kW overall CFA ceiling is eligible. In the guideline example, the additional eligible amount is ₹48,000.

A rooftop-solar installation is eligible for CFA only once after installation. Relocating an already subsidised plant to another address does not create a new claim.

PM Surya Ghar Subsidy for RWA and Group Housing Common Facilities

Group Housing Societies, Residential Welfare Associations, Apartment Owner Associations and similar resident entities can receive assistance for eligible common-facility installations, including EV charging. The supported capacity is limited to the lower of:

• The actual common-facility rooftop-solar capacity;
• 3 kW multiplied by the number of houses; or
• The overall programme ceiling of 500 kW.

The standard RWA rate is ₹18,000 per eligible kW, while the special-category rate is ₹19,800 per eligible kW. Individual rooftop plants already installed by residents are included when applying the supported-capacity ceiling.

Can a State Add Its Own Solar Subsidy?

Yes. A State or Union Territory government may supplement the Central Financial Assistance with an additional rooftop-solar subsidy, provided its framework aligns with the scheme guidelines. Such support is not identical across India and may change through state notifications, budgets or eligibility rules.

• Do not assume every State pays a top-up.
• Do not use an old social-media amount without checking the notification date.
• Do not count a proposed or announced benefit as approved money.
• Do not confuse a DISCOM rebate, loan support or tariff credit with Central CFA.

Check the current National Portal, State renewable-energy agency and concerned DISCOM before adding a state benefit to the financial calculation.

How and When Is the Subsidy Paid?

Central Financial Assistance is not normally an advance paid before the rooftop system is installed. The consumer follows the official application and registered-vendor process, completes installation, uploads relevant documents, undergoes DISCOM inspection and finishes the bank and e-token actions shown on the portal.

1. Submit the consumer application through the National Portal.
2. Install the eligible system through a registered vendor.
3. Upload plant details, documents and required geo-tagged photographs.
4. Complete DISCOM inspection and the applicable metering process.
5. Receive activation of the e-token for the eligible actual capacity.
6. Redeem the e-token and complete bank validation.
7. Track the CFA credit or loan-account adjustment.

The official guidelines provide for CFA processing within 15 days of approval by the concerned DISCOM. A PIB explainer also described an average processing period of around 15 days after a correctly completed redemption request. This does not guarantee bank credit 15 days after initial registration or vendor payment.

Frequently Asked Questions About PM Surya Ghar Subsidy

Calculate the CFA First, Then Compare the Real Project Cost

Use the installed eligible module capacity to calculate the central assistance: ₹30,000 per kW for the first 2 kW and ₹18,000 for the next 1 kW in standard-category areas. Then compare registered-vendor quotations on the same technical scope. A cheap quotation with weak structure, excluded electrical work or non-compliant modules can cost more later.

Before paying, confirm whether the connection and system are eligible , review the documents needed for inspection and bank verification , and complete the claim only through the official application flow.
