Electricity bills in India have only been climbing, and the government’s answer has been to make rooftop solar as financially painless as possible. Between the central PM Surya Ghar scheme and a growing list of state-level top-ups, a lot of households can now cover a serious chunk of their installation cost through subsidies alone. The tricky part is that the rules aren’t identical everywhere. Here’s how the system actually works, and what you can realistically expect to receive.
The Central Scheme: PM Surya Ghar Muft Bijli Yojana
The foundation of India’s rooftop solar push is PM Surya Ghar Muft Bijli Yojana, launched in February 2024 with a target of bringing solar to one crore households and adding roughly 30 GW of rooftop capacity nationwide. The scheme has scaled up quickly. By mid-2026, the program had crossed roughly 39 lakh installations across more than 48 lakh households, backed by a budget allocation of over ₹75,000 crore.
The central subsidy itself is tiered by system size: ₹30,000 for a 1kW system, ₹60,000 for 2kW, and ₹78,000 for a 3kW system or larger. That last number is a hard ceiling. Installing a bigger system than 3kW doesn’t get you more central subsidy, since the maximum caps out at ₹78,000 regardless of how large your rooftop array actually is. For most households, this makes 3kW something of a sweet spot, typically covering somewhere in the range of 30–40% of a standard system’s total cost.
Why State-Level Subsidies Matter Just as Much
Here’s where things get more interesting, and more confusing. The central subsidy is the same no matter where you live in India, but a number of states and union territories layer their own additional financial assistance on top of it. As of 2026, roughly 14 states and UTs offer some form of extra state-level support, while the rest of the country relies primarily on the central subsidy alone.
The size and structure of these state top-ups vary considerably. Some states offer a flat additional rupee amount per kW, while others structure their support differently, through capital subsidies, interest subsidies on solar loans, or other mechanisms. Rajasthan, for example, has offered an additional state top-up in the range of ₹17,000, subject to specific conditions. States like Gujarat and Maharashtra are also frequently cited among the more generous combined central-plus-state packages available. If you don’t check your specific state’s rules, you could easily leave meaningful money on the table.
How Much Can You Actually Get, Combined?
Add central and state support together, and the combined benefit for households in more generous states can cross ₹1 lakh in total subsidy for a single installation. That’s a substantial dent in the cost of a typical residential system, especially for households sized around the 3kW mark where the central subsidy maxes out.
Beyond direct subsidies, the scheme also opens the door to collateral-free loans of up to ₹2 lakh to help cover whatever cost remains after subsidies are applied. That combination, upfront subsidy plus accessible financing, is specifically designed to remove the two biggest barriers that have historically kept Indian households from going solar: the large lump-sum cost and the lack of easy credit for it.

How to Actually Apply for the Subsidy
The application process runs through the National Portal for Rooftop Solar, and it follows a fairly standard sequence. You register on the portal and select your state, district, and electricity distribution company. Next, you enter your consumer account number so the portal can pull up your existing connection details. From there, you choose a registered, empanelled vendor listed on the portal and place your order for the system.
Once the vendor completes installation, your local DISCOM carries out an inspection and approves the grid connection. Only after that verification is complete does the central subsidy get transferred directly to your bank account. It’s worth noting that eligibility requires you to actually own the rooftop (or have proper authorization to install on it), hold a valid electricity connection in your own name, and not already have an existing rooftop solar system.
Frequently Asked Questions
1. Do I automatically get both the central and state subsidy, or do I need to apply separately?
It depends on your state. The central subsidy is applied for through the PM Surya Ghar national portal. Many states with their own top-up schemes have a separate or linked application process through the state nodal agency or DISCOM, so it’s worth checking your specific state’s solar department for the exact steps.
2. Why does the central subsidy cap out at 3kW instead of scaling with larger systems?
The scheme was designed to make solar accessible for typical household consumption levels, and 3kW covers most average residential needs. Larger systems are still allowed and can make sense for bigger homes or higher consumption, but the central government’s financial assistance doesn’t increase beyond the 3kW threshold.
3. Is the subsidy available for commercial or industrial rooftop solar too?
No, PM Surya Ghar specifically covers residential rooftop solar. Commercial and industrial consumers have separate incentive routes available, including accelerated depreciation benefits and various state-specific industrial solar programs, but these work differently from the residential subsidy structure.
4. How long does it take to actually receive the subsidy after installation?
After your vendor completes installation and your DISCOM carries out its inspection and grid connection approval, the subsidy is typically credited to your bank account within roughly 30 to 45 days, though this can vary depending on how quickly your local DISCOM processes the inspection.
