Solar Subsidy in bihar in 2026: How to Apply and Cost Included You Should Know
With rising electricity tariffs and increasing power demands, transitioning to clean energy has evolved from a luxury into a smart financial investment for homeowners across India. If you reside in Bihar—whether under the coverage of North Bihar Power Distribution Company Limited (NBPDCL) or South Bihar Power Distribution Company Limited (SBPDCL)—the year 2026 is the best time to switch to solar energy.
Through the combination of the central government’s PM Surya Ghar: Muft Bijli Yojana and state-level renewable initiatives via the Bihar Renewable Energy Development Agency (BREDA), tapping into a Solar Subsidy in bihar can lower your upfront setup cost, slash your monthly power bills, and provide up to 300 units of free electricity every month.
Understanding how much financial assistance you will receive is the first step before calling an installer. Under the central PM Surya Ghar initiative, the Central Financial Assistance (CFA) provides a fixed grant structure directly credited to your bank account via Direct Benefit Transfer (DBT):
1 kW Rooftop System: ₹30,000 central assistance.
3 kW Rooftop System (and above): Capped at ₹78,000 central assistance. When you leverage the state-supported Solar Subsidy in bihar, the effective financial grant for a standard 3 kW system can significantly offset your capital expenditure.
| Solar System Capacity | Central Subsidy (CFA) | State Top-Up Assistance | Max Effective Subsidy Benefit |
| 1 kW System | ₹30,000 | ₹10,000 | ₹40,000 |
| 2 kW System | ₹60,000 | ₹20,000 | ₹80,000 |
| 3 kW System | ₹78,000 | ₹20,000 | ₹98,000 |
| Above 3 kW | ₹78,000 (Max Cap) | ₹20,000 (Max Cap) | ₹98,000 |
By claiming the official Solar Subsidy in bihar, residential property owners can recover up to 50–60% of their initial setup costs right at the start.

4. Step-by-Step Application Process (2026 Online Portal)
Getting your Solar Subsidy in bihar requires following an official step-by-step workflow.
Step 1: Registration on the National Portal
Visit the official PM Surya Ghar Portal (pmsuryaghar.gov.in). Select Bihar as your state, choose your utility company (NBPDCL or SBPDCL), enter your Consumer Account Number, mobile number, and email address.
Step 2: Technical Feasibility Approval (TFR)
Log in with your registered consumer details and submit a formal application for Rooftop Solar. Your local DISCOM will review your rooftop feasibility and approve the application online.
Step 3: Choose an Empanelled Vendor
Once feasibility is granted, select an installer registered with BREDA and your DISCOM. Always execute a formal agreement with an empanelled vendor to remain eligible for the Solar Subsidy in bihar.
Step 4: Plant Installation & Document Upload
The vendor installs the grid-tied system using ALMM-compliant solar modules. After completion, upload the system details, panel serial numbers, and invoice copies to the national portal.
Step 5: Inspection and Net Metering Installation
DISCOM officials will inspect the setup, verify the installation, and install a bi-directional net meter on your premise. A Commissioning Certificate will then be issued online.
Step 6: Subsidy Direct Benefit Transfer (DBT)
Submit your bank account details and upload a cancelled cheque on the portal. The calculated Solar Subsidy in bihar (combining central CFA and state top-up) will be transferred directly to your bank account within 30 days of commissioning.

Investing in a rooftop solar plant yields high financial returns. A standard 3 kW system in Bihar generates roughly 12 to 14 units per day, or around 4,000 units annually.
At average retail tariff rates of ₹7 per unit, a 3 kW system saves approximately ₹28,000 per year on electricity bills. Since your net out-of-pocket investment after claiming the Solar Subsidy in bihar is approximately ₹65,000–₹85,000, your complete payback period takes just 2.5 to 3 years.
