Bihar, one of India’s fastest-developing states, is now making rooftop solar more affordable for its residents. With national schemes and state support, the Bihar Solar Subsidy has become an accessible route to cleaner energy and lower electricity bills.
What Subsidies Are Available?
Under the national programme Pradhan Mantri Surya Ghar: Muft Bijli Yojana and state-level encouragement, residential rooftop systems in Bihar can claim subsidy benefits:
• Up to ₹ 30,000 per kW subsidy for smaller systems (1 kW).
• For systems up to approximately 3 kW, a fixed subsidy of ~₹ 78,000 often applies under combined central & state support.
• Additional state incentives may be available through the Bihar Renewable Energy Development Agency (BREDA) when available.
Cost & Savings:
A typical 3 kW rooftop solar system in Bihar may cost around ₹ 1.8 to 2.2 lakh before subsidy. With a subsidy of ~₹ 78,000, the net cost can drop to ~₹ 1.0 to 1.4 lakh.
With consistent power generation, monthly electricity bill savings, and available net-metering mechanisms, many homeowners achieve a payback period in approximately 4-6 years, after which energy savings continue for decades.
Conclusion:
With falling installation costs, increasing electricity tariffs, and strong solar irradiation in Bihar, the subsidy makes rooftop solar a highly viable investment. It’s a meaningful opportunity for households to reduce their bills, contribute to a greener future—and achieve clean energy independence.
