Electricity bills in India, including Bihar, rise by 3-6% every year, making the already expensive grid power costlier. Rooftop solar can fix this problem by generating free electricity from sunlight for 25+ years, lowering bills by at least 90%. In 2026, solar adoption has become extremely affordable through the solar panel subsidy in Bihar.

  • Under the PM Surya Ghar Muft Bijli Yojana, households can receive Rs. 30,000 per kW for the first 2 kW and another Rs. 18,000 for the third kW.
  • The maximum subsidy is capped at Rs. 78,000 for systems of 3 kW or higher.

Homeowners in Bihar can get a subsidy only under this scheme. It is the only active solar subsidy scheme, and there’s no specific state-level solar panel subsidy in Bihar for general households.

This blog breaks down the process to apply for a solar panel subsidy in Bihar, the exact financial assistance you can get (and under what eligibility conditions) under the PM Surya Ghar Muft Bijli Yojana in Bihar, the mistakes that can delay the subsidy or make you ineligible for it, and the benefits of solar energy subsidy in Bihar.

Understanding Bihar’s Solar Ecosystem: Key Institutions

Before applying for rooftop solar in Bihar, you should know about the three bodies involved in the process, as each has a different role.

  • BREDA (Bihar Renewable Energy Development Agency): BREDA is the state nodal agency for renewable energy in Bihar. It implements solar programs statewide, runs awareness campaigns, and coordinates rooftop solar adoption at the state level.
  • NBPDCL (North Bihar Power Distribution Company Limited): NBPDCL is the DISCOM that distributes electricity across 21 districts of North Bihar, including Muzaffarpur, Darbhanga, Sitamarhi, Madhubani, Begusarai, Purnia, and Katihar. If your electricity connection falls in any of these districts, NBPDCL is your distribution company (DISCOM).
  • SBPDCL (South Bihar Power Distribution Company Limited): SBPDCL is the DISCOM that distributes electricity across 17 districts of South Bihar, including Patna, Gaya, Bhagalpur, Nalanda, Aurangabad, Munger, and Rohtas.

Is There any Special Bihar Govt Subsidy on Solar Panels?

No, there is no separate Bihar government solar subsidy that adds to the central subsidy offered under the PM Surya Ghar Muft Bijli Yojana for general households. Bihar offers a single subsidy for most consumers, with only one targeted subsidy scheme reserved for below-poverty-line families.

  • PM Surya Ghar Muft Bijli Yojana is the only subsidy on solar panels in Bihar for above-poverty-line consumers: If you are a regular domestic consumer, your grant comes entirely from the central government, and is capped at Rs. 78,000.
  • Kutir Jyoti Yojana for BPL families only: Kutir Jyoti Yojana is the Bihar govt subsidy on solar panels for below-poverty-line households. The overall target under this scheme is to cover 58.89 lakh BPL homes. In the 1st phase, Bihar targeted 2.5 lakh Kutir Jyoti consumers. The application window for this phase ran from February 28th to March 31st, 2026. Families who missed the 1st phase do not lose eligibility forever. They can apply when the next phase is announced.

All homeowners eligible for the Bihar solar panel subsidy under the PM Surya Ghar Muft Bijli Yojana need to create an account on the PM Surya Ghar Muft Bijli Yojana National Portal for Rooftop Solar to apply for and receive the subsidy grant directly into their bank accounts.

You can follow these simple steps to apply for the PM Surya Ghar Muft Bijli Yojana solar panel subsidy in Bihar.

  • Step 1 – Access the solar portal: Open the PM Surya Ghar Muft Bijli Yojana National Portal for Rooftop Solar and click the rooftop solar application section.

  • Step 3 – Fill in your details: Share your name and age, and enter the relevant numbers from your most recent electricity bill.
  • Step 4 – Add your banking details: Upload the required supporting documents, provide your bank account information, and attach a copy of a cancelled cheque.
  • Step 5 – Finalize an empanelled vendor: Review the list of DISCOM-approved installers on the portal and pick the vendor you want to hire.
  • Step 6 – Review, sign, and upload the agreement: Go through the installer agreement, sign it, and upload the signed version to the portal.
  • Step 7 – DISCOM installs the net meter: After your solar system is installed, DISCOM installs a bi-directional net meter or smart meter.

What are the Benefits of a Subsidy on Solar Panels in Bihar?

The solar subsidy in Bihar directly reduces the cost of installing rooftop solar. For eligible homes, financial assistance can be up to Rs. 78,000 for systems of 3 kW or more.

Let’s look at the advantages of a solar panel subsidy in Bihar in detail.

  • Lower installation cost: The subsidy reduces the amount you need to pay out of pocket. This makes rooftop solar easier to afford for most households.
  • Faster payback: Since the final installation cost gets lower after the subsidy, electricity bill savings recover the investment sooner.
  • Direct payment to your bank account: The subsidy is transferred through Direct Benefit Transfer (DBT) after the system is installed and commissioned.
  • Easier financing for the remaining amount: After the subsidy, the remaining balance is smaller. And that, too, can be funded through a PM Surya Ghar solar loan from PSU banks or solar financing schemes by NBFCs.

Common Mistakes that Can Make You Ineligible for the Bihar Government Solar Subsidy

The solar subsidy you are eligible for in Bihar can be delayed or rejected if the basic rules are not followed. Therefore, before applying, check for these common mistakes.

  • Choosing an unapproved installer: Only an empanelled solar vendor and ALMM-approved solar panels make you eligible to receive the subsidy. If you choose an unapproved installer or non-approved panels, you lose subsidy eligibility.
  • Document name mismatch: The name on your electricity bill, Aadhaar, and bank account should match. If the names differ, verification and subsidy transfer may be delayed.
  • Installing a system larger than your sanctioned load: Your solar system size should not exceed the sanctioned load on your electricity connection. If it is oversized, the application may fail the feasibility check. In such cases, you should first file an application with your DISCOM for an increase in the sanctioned load.
  • Applying with a commercial connection: The rooftop solar subsidy in Bihar is available only to residential consumers. Commercial and industrial electricity connections are not eligible for the household subsidy.

Conclusion

2026 is the best time to go solar, not just in Bihar but across the country, thanks to the hefty subsidy grant of Rs. 78,000 offered by the central government, making rooftop solar affordable for all. However, this subsidy grant will be offered only until the government solarizes 1 crore homes in the country under this scheme.

Clearly, a subsidy on rooftop solar will not be offered forever. The deadline to achieve this target has been set as March 31, 2027, making now the best time to install solar at cheaper rates.

FAQs

What is the subsidy for a 3 kW solar panel in Bihar?

Eligible homeowners can claim a subsidy of Rs. 78,000 for installing a 3 kW grid-tied solar system in Bihar.

Who manages rooftop solar applications in Bihar?

Three bodies handle different parts of the process.

  • NBPDCL for North Bihar consumers: It serves as the authority for feasibility and net metering approvals for the 21 northern districts in Bihar.
  • SBPDCL for South Bihar consumers: It plays the same role as NBPDCL for the 17 southern districts, including Patna.
  • MNRE and the PM Surya Ghar Muft Bijli Yojana National Portal: These manage the central subsidy itself, from application to the final DBT credit.

Can tenants apply for a solar panel subsidy in Bihar?

Yes, tenants can apply, but they need a No Objection Certificate (NOC) from the property owner. The subsidy is credited to the person whose name is registered on the electricity connection, so the application and the connection details must align.

Can BPL families apply for a solar panel subsidy in Bihar?

Yes, below poverty line families are served through the Bihar government’s Kutir Jyoti Yojana. Under the 2026 Kutir Jyoti program, the state is installing rooftop solar on lakhs of BPL households, free of cost.

What does 300 units of free electricity under PM Surya Ghar mean?

Against the common notion that the government offers 300 free electricity units, it means a correctly sized rooftop system, usually around 3 kW, generates ~300 units of electricity each month, which is close to what an average household consumes.

  • You use your own generation throughout the day.
  • Net metering credits the surplus you export against the units you draw at night.

The word free refers to this exact offset through self-generation. As a result, your bill drops to a small fixed charge or nearly zero. It is not a cash payment or a waiver from your DISCOM.

How long does it take to get a solar panel subsidy in Bihar?

The subsidy is paid within 30 days of your system being commissioned. Commissioning happens after installation, the net meter setup, and the DISCOM inspection. So, the 30-day clock starts once your system is officially live.

Is rooftop solar free in Bihar?

This applies only to BPL families applying for solar through the Kutir Jyoti Yojana. Under this scheme, a rooftop solar system of 1.1 kW is installed on the roof of the BPL household completely free of cost.

For general households, this is not true. A solar panel subsidy in Bihar under the PM Surya Ghar Mift Bijli Yojana can reduce the installation cost by up to Rs. 78,000 for systems with a capacity of 3 kW or higher. But rooftop solar installation is not free.

Can commercial users get a solar subsidy in Bihar?

No, they can’t. The PM Surya Ghar Muft Bijli Yojana offers a subsidy only to residential consumers, including homes and housing societies. There is no such financial assistance for commercial solar users. What commercial and industrial solar consumers get from rooftop solar is lower bills and accelerated depreciation for tax purposes.

Is there a solar subsidy for farmers in Bihar separate from PM Surya Ghar?

Yes, farmers have a separate scheme called PM-KUSUM Yojana, which supports solar water pumps and small solar plants for agricultural use. PM Surya Ghar Muft Bijli Yojana covers household rooftops, while PM-KUSUM Yojana is designed for farm energy needs.
