PM Surya Ghar in 2026: What the Rooftop Boom Means for BOS Supply

If you install or supply solar in India, you’ve felt it: every other residential enquiry now starts with “Is this under the subsidy scheme?” That’s PM Surya Ghar, and it has turned rooftop solar from a slow trickle into a flood. Behind every one of those rooftops sits a full set of BOS materials — and that’s where the real supply pressure is showing up.

Drop-cap opening paragraph: The numbers tell the story. Since launching in February 2024, PM Surya Ghar: Muft Bijli Yojana had crossed roughly 26 lakh rooftop installations and about 9.56 GW of capacity by March 2026, according to MNRE figures shared in Parliament. [verify latest] The scheme is aiming for one crore (10 million) households by FY 2026–27. Rooftop installs in Q1 2026 ran about 125% higher year-on-year, per Mercom India, with the residential segment alone making up roughly 82% of those additions. [verify]

Why This Matters Most in Gujarat

Here’s the part that hits close to home for anyone supplying out of Rajkot. As of early 2026, Gujarat led the entire country on rooftop capacity under the scheme — ahead of Maharashtra and Rajasthan. [verify] That means the densest concentration of new rooftop projects, and the highest demand for BOS material, is happening right where a Gujarat-based supplier can serve it fastest.

For installers, that’s both an opportunity and a squeeze: more projects, but tighter timelines and thinner margins. The fastest-growing problem isn’t finding customers — it’s getting quality material in hand without delays.

Every Rooftop Needs a Full BOS Set

It’s easy to focus on panels and the inverter and treat everything else as an afterthought. But a subsidy-eligible rooftop doesn’t switch on without the rest of it:

• Mounting structure — sized and fixed for the roof type
• DCDB — DC-side protection before the inverter
• ACDB — AC-side protection after it
• DC cable (4/6mm² copper) — panels to inverter
• AC cable — inverter to the connection point
• Earthing cable (16/50 sqmm aluminium) — system grounding and lightning protection
• J-bolts, clamps, monorail accessories — to fix it all down securely

Multiply that by the volume the scheme is generating and you can see why ready stock and fast dispatch matter more than they ever did.

The scheme created the demand. Execution is what will decide who keeps the customer. Mercom’s own read on 2026 is that the next phase of growth depends less on interest and more on installation quality and on-ground delivery.

The Bottleneck Is Execution, Not Interest

Industry analysts have been blunt about this: consumer demand is no longer the constraint. What slows the residential boom now is approvals, financing, DISCOM coordination — and getting good material on site on time. For a contractor, a project stalled for want of a mounting structure or a DCDB isn’t just a delay; it’s a subsidy timeline at risk and a customer losing patience.

That’s the real value of a reliable BOS supplier in this market: not the cheapest line item, but the one that keeps your schedule intact.

A Note on Compliance

PM Surya Ghar has rules. Modules must be ALMM-listed to qualify for the Central Financial Assistance, and inverters carry their own certification requirements. BOS components don’t have the same single approved list yet, but quality and certification still matter — both for safety and for the system lasting the 25 years the subsidy assumes. (More on standards in our compliance guide.)

FAQ

Is PM Surya Ghar still running in 2026? Yes. It’s the central government’s flagship residential rooftop scheme, targeting one crore households by FY 2026–27. [verify status]

Does the subsidy cover BOS materials? The Central Financial Assistance is structured around system capacity rather than line-item components, but a complete, compliant system necessarily includes BOS materials. Always check current scheme guidelines.

Where’s demand highest? Residential rooftop dominates, and Gujarat, Maharashtra, and Rajasthan have led on capacity. [verify]

Conclusion + CTA

The rooftop boom is real, it’s residential, and it’s concentrated in states like Gujarat. The contractors who win in it will be the ones who can move fast without compromising on quality — and that starts with reliable BOS supply.
