Solar Subsidy in Bihar: PM Surya Ghar Muft Bijli Yojana & DISCOM Process
The Government of India's PM Surya Ghar: Muft Bijli Yojana combined with state and EKOSYS assistance has transformed the economics of residential solar energy across Bihar. By providing up to ₹1,13,000 in total financial assistance, the program makes clean energy accessible and affordable for independent homeowners.
Key Engineering Takeaways
- PM Surya Ghar Central DBT (₹78,000) + Extra Special State Subsidy (₹20,000) + EKOSYS Assistance (₹15,000) = ₹1,13,000 Total Benefit for residential solar.
- Subsidy is paid directly into the consumer's bank account via Direct Benefit Transfer (DBT).
- Only grid-connected residential rooftop systems using DCR-compliant (Made in India) modules are eligible.
- EKOSYS provides full assistance from National Portal registration to net-meter commissioning.
1. Current Subsidy Slabs for Residential Solar in Bihar
The subsidy structure under the PM Surya Ghar scheme is standardized across all states including Bihar, administered through the National Rooftop Solar Portal.
For 3 kW and higher residential installations, homeowners receive PM Surya Ghar Central DBT (₹78,000) + Extra Special State Subsidy (₹20,000) + EKOSYS Assistance (₹15,000) = ₹1,13,000 Total Subsidy Benefit.
- 1 kW Rooftop Solar System: ₹30,000 Central DBT + State/EKOSYS Assistance (Up to ₹55,000 Total)
- 2 kW Rooftop Solar System: ₹60,000 Central DBT + State/EKOSYS Assistance (Up to ₹90,000 Total)
- 3 kW and larger Systems: PM Surya Ghar Central DBT (₹78,000) + Extra Special State Subsidy (₹20,000) + EKOSYS Assistance (₹15,000) = ₹1,13,000 Total Benefit
- Group Housing Societies / Residential Welfare Associations (RWA): ₹18,000 per kW for common facilities (up to 500 kW)
2. Eligibility Conditions & DCR Module Compliance
To qualify for the central subsidy, the solar installation must satisfy three non-negotiable requirements:
1. The applicant must be a residential consumer with an active domestic electricity connection under NBPDCL or SBPDCL.
2. The solar PV modules used must be Domestic Content Requirement (DCR) compliant—meaning both the solar cells and modules are manufactured in India and listed on the MNRE Approved List of Models and Manufacturers (ALMM).
3. The system must be grid-connected with an approved bi-directional net meter installed by the DISCOM.
3. Step-by-Step Subsidy Application Process
The application journey follows a systematic 5-stage verification process on the national portal:
Stage 1: Register on the PM Surya Ghar portal using your mobile number, state (Bihar), DISCOM name (NBPDCL/SBPDCL), and Electricity Consumer Account Number.
Stage 2: Submit online technical feasibility application. The DISCOM verifies local transformer capacity and issues technical sanction.
Stage 3: System installation by an empanelled/registered solar vendor like EKOSYS using ALMM/DCR-certified components.
Stage 4: Submit work completion report, module serial numbers, inverter test certificates, and request DISCOM net meter inspection.
Stage 5: Following net-meter commissioning, upload bank account details (cancelled cheque). The subsidy is released via DBT within 30 to 45 days.
