Bihar is among the sunniest states in India and, with 2026 coming around the corner it’s also among the most exciting areas to get solar. The central government’s PM Surya Ghar: Muft Bijli Yojana providing subsidies of up to ₹ 78,000 and a maximum of ₹ 78,000, there’s never been a better time to encourage Bihar homeowners to set up solar panels on their roofs and cut their power bills forever. However, despite receiving over 54,000 requests, Bihar continues to have one of the lowest rooftop solar installation rates in India relative to its population. As a result, many families miss the opportunity to benefit from government subsidies and significantly reduce their monthly electricity costs. Furthermore, this slow adoption limits access to long-term savings and clean energy solutions.
This comprehensive guide from Usha Solar will walk you through all you need to know regarding the subsidy for solar panels offered in Bihar. It covers what you can save, who’s eligible for the subsidy, how to apply step-by-step and the reasons why selecting the best solar provider is important.
Why Bihar Is Perfect for Solar Energy
Before we get into subsidy programs first, let’s look at the reasons why solar power is an investment that is highly beneficial to Bihar residents:
Unstoppable Sunlight Year-Round Bihar is blessed with five to 5.5 maximum sun hours each day, which gives it an exceptional sun energy capacity. Rooftop solar panels produce huge output, not only in summer, but throughout the year, ensuring stable power, even when load-shedding is in effect.
Increased Electricity Costs Electricity tariffs in Bihar under SBPDCL and NBPDCL have been steadily increasing in the past five years. A solar panel locks your energy costs at a near-zero level for the next 25 years or more and protects your home from any future price hikes.
Load Shedding Relief In semi-urban and rural Bihar power interruptions continue to be a constant problem. A solar-powered system and batteries backup – will give you power for as long as the grid is down.
Net Metering benefits Bihar’s Net Metering policy, which is managed through BSPHCL (Bihar State Power Holding Co. Limited) through SBPDCL and NBPDCL which allows you to sell surplus solar energy back to the grid. Extra units are credited to your electricity bill which makes your investment more efficient.
What Is the Solar Panel Subsidy in Bihar?
The solar subsidies that are available to Bihar residents is provided from the government’s Surya Ghar: Muft Bijli Yojana which is a major central government program that was launched in February 2024, with an outlay of ₹75,021 crore, which covers more than one crore households in India.

As of March 2026, the scheme had already benefited more than 32 lakh households across India and distributed over ₹14,771 crore in subsidies. Furthermore, Bihar has disbursed ₹102.27 crore in subsidies so far. In addition, the state is actively expanding its solar infrastructure, with a 275 MW tender launched through SBPDCL and NBPDCL. Consequently, Bihar is making significant progress toward wider rooftop solar adoption and clean energy development.

Usha Solar’s team helps clients in navigating the loan application process and solar installations to make the process simple and easy.
The Bihar Net Metering Program: Make Money from Your Rooftop
In Bihar’s net metering policies, the solar system you have installed connects to grid using the bidirectional meters. Any extra electricity that the panels produce that exceeds the needs of your home’s power is transferred into the grid.
How does it work:
- Your bidirectional meter records both imported (consumed) and exported (surplus) electricity units.
- You pay only for your net energy usage after adjusting exported units against imported units.
- The system carries forward any unused credits to the next billing cycle.
- The period for settlement is monthly.
This means that a 3 KW system that generates the equivalent of 400 units a month, versus the consumption of a typical household of 250 units gives you 150 units of credit, basically a negative electric bill during Bihar’s hottest months.
Bihar’s Solar Expansion in 2026: A Growing Opportunity
Bihar’s rooftop solar program is growing rapidly by 2026:
- SBPDCL along with NBPDCL have launched an invitation to tender for 275 MW in rooftop solar power capacity over all 18 distribution circles within the state in the PM Surya Ghar: Muft Bijli Yojana utility-led Aggregation (ULA) model.
- Bihar Renewable Energy Development Agency (BREDA) is actively helping to promote solar adoption through awareness programs and local assistance
- The scheme offered by the central government will be in effect until 2026-27. This gives Bihar residents ample time to take action and get the maximum benefits before the current phase is over.
