max central subsidy (3 kW+)
PM Surya Ghar subsidy window: 31 March 2027
The ₹78,000 central residential subsidy is sanctioned through the end of FY 2026-27 (31 March 2027). Apply and get commissioned well before this date. No extension has been officially notified; MNRE has indicated the one-crore-household target may fall short by March 2027, which makes an extension plausible but not assured — plan around the published date.
As of October 2026 — confirm the current position on pmsuryaghar.gov.in.
Central Subsidy Structure (National)
The PM Surya Ghar: Muft Bijli Yojana subsidy is uniform across India, including Bihar. It is credited directly to the applicant’s bank account after commissioning and inspection.
| System capacity | Central assistance |
|---|---|
| First 2 kW | ₹30,000 per kW |
| Third kW | ₹18,000 per kW |
| Above 3 kW | No additional central subsidy (max ₹78,000) |
Bihar State Subsidy — On Top of the Central Amount
Bihar adds
₹10,000/kW (up to ₹20,000) via the Mukhyamantri Solar Protsahan Yojana
Bihar launched the Mukhyamantri Solar Protsahan Yojana on 22–23 September 2026, adding state assistance on top of the central PM Surya Ghar subsidy: reported at ₹10,000 for a 1 kW system, ₹20,000 for 2 kW and up to ₹20,000 for 3 kW and above — so a 3 kW home can receive up to ₹98,000 in total. Reports say about 25,000 beneficiaries have already received the state payment by direct transfer. The reports we found do not spell out eligibility conditions or the application steps, so confirm both with your DISCOM (NBPDCL or SBPDCL) or BREDA before you budget around the state amount.
Reported figures for Bihar vary across sources. Treat the above as indicative and confirm the live amount and eligibility with the state agency before committing.
Bihar’s state amount rests on press reports of the September 2026 launch; also a free-solar programme for Kutir Jyoti homes
We could not find the scheme’s official text, so the ₹10,000 / ₹20,000 / up to ₹20,000 amounts come from consistent reports in several newspapers (Amar Ujala, Prabhat Khabar, Patna Press and Saur Energy) of the launch event, which also say about 25,000 beneficiaries have been paid. No report states who is eligible or how to apply, and "3 kW and above" is described only as "up to ₹20,000", so for 5 kW and 10 kW systems we apply the same ₹20,000 cap — confirm that these sizes qualify. Separately, Bihar is reported to be installing free rooftop solar of about 1.1 kW for households in its Kutir Jyoti category under a utility-led RESCO model, with ten years of maintenance and up to 125 free units a month; that programme is not part of our figures, and if you are a Kutir Jyoti consumer you should ask your DISCOM about it before buying your own system.

What Will a System Generate in Bihar?
At Bihar’s typical solar resource of ~4.9 peak sun hours per day and a realistic 78% performance ratio, each kW of rooftop solar produces about 116 units/month (1,395 units/year). A common 3 kW residential system therefore generates roughly 348 units/month — compare that against your electricity bill to gauge coverage.
