PM Surya Ghar Muft Bijli Yojana is a national government scheme launched by Prime Minister Narendra Modi to provide free electricity to households by promoting rooftop solar installation. Under this scheme, substantial financial subsidies (up to ₹78,000) are credited directly into your bank account via Direct Benefit Transfer (DBT) to reduce the cost of solar panels.
The subsidy depends on the capacity of your solar plant:
• Up to 2 kW: ₹30,000 per kW (₹60,000 for 2 kW)
• Additional capacity up to 3 kW: ₹18,000 per kW
• Maximum Subsidy Cap: ₹78,000 for residential systems of 3 kW and above.
The entire subsidy amount is transferred directly to your bank account via Direct Benefit Transfer (DBT) upon net-meter commissioning.
Any Indian household with a suitable, shadow-free roof for solar installation and a valid domestic electricity connection (such as WBSEDCL in West Bengal) can apply. The applicant must have roof ownership rights and must not have availed any previous solar subsidy on the same consumer meter.
On average, a 3 kW solar system can save you ₹3,000 to ₹4,000 per month on electricity bills. Over 25 years (the lifespan of Tier-1 solar panels), cumulative savings amount to lakhs of rupees (₹9 to ₹12 Lakhs), delivering complete capital payback within 3 to 4 years.
No, PM Surya Ghar Muft Bijli Yojana is primarily for residential households. However, commercial, institutional, and industrial sectors have attractive schemes and incentives, including 40% accelerated tax depreciation under Section 32 of the Income Tax Act and custom commercial net-metering solutions provided by Dutta Solar Enterprise.
You need your latest electricity bill, Aadhaar card, bank account details (cancelled cheque or passbook copy for DBT transfer), and proof of roof ownership. Dutta Solar Enterprise assists you in uploading these documents and completing all national portal formalities without any hassle.
The subsidy amount of up to ₹78,000 is generally credited to the beneficiary's bank account within 30 days of submitting the net meter installation report and commissioning certificate on the national portal.
Approximately 300 square feet of shadow-free roof area is required for a 3 kW solar plant. It should ideally face south for maximum generation. With Dutta Solar's elevated walkway structures (7 to 8 feet high), you also retain 100% usable, walkable roof space underneath.
Grid-connected solar systems automatically shut down during a power cut for safety reasons (anti-islanding protection to keep WBSEDCL utility line technicians safe). If you need power during outages, you need a hybrid system with battery backup, which Dutta Solar Enterprise can custom design for your home.
Yes, they still generate electricity on cloudy days using diffused sunlight, operating at approximately 20% to 30% of full capacity. They do not generate power at night. Any shortfall is seamlessly drawn from the grid through WBSEDCL net-metering.
Once the approvals are in place, the physical installation of the solar plant on your roof takes only 1 to 2 days. The entire process including WBSEDCL net metering approval and meter changeover takes approximately 2 to 4 weeks.
Solar panels typically come with a 25-year performance warranty (guaranteeing ≥80% output at Year 25). Inverters usually have a 5 to 10-year warranty, and workmanship and structural warranty are provided by Dutta Solar Enterprise.
Solar systems have no moving parts and require very low maintenance. You just need to clean the panels with clean water every couple of weeks to remove dust and bird droppings for maximum efficiency.
No, absolutely not. We use non-penetrating chemical anchor fasteners with heavy-duty rubber gasket isolation seals. No drilling compromises your roof’s waterproofing layer. In fact, the solar canopy shields your concrete slab from intense sun and heavy monsoon rains, prolonging your roof slab’s lifespan and lowering room temperatures below.
