Turn Bengal’s Sunlight Into Free Power.
Zero Electricity Bills for the Next 25 Years.

The subsidy depends on the capacity of your solar plant under official MNRE guidelines:
• 1 kW System: ₹30,000 Direct Central DBT (Generates 5 units/day, cost ~₹70,000).
• 2 kW System: ₹60,000 Direct Central DBT (Generates 10 units/day, cost ~₹1,40,000).
• 3.2 kW System & Above: ₹78,000 Maximum Central DBT Cap (Generates 16 units/day, cost ~₹2,10,000).
The entire subsidy amount is transferred directly to your Aadhaar-linked bank account via Direct Benefit Transfer (DBT).

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 3.2 kW solar system generates approximately 16 units per day (~480 units per month), which cuts your recurring monthly WBSEDCL power bill to literally ₹0. Over 25 years (the guaranteed lifespan of Tier-1 solar panels), cumulative savings amount to lakhs of rupees (₹9 to ₹12+ Lakhs), delivering complete capital payback in under 3 years.

No, PM Surya Ghar Muft Bijli Yojana is specifically for residential households. However, commercial, institutional, and industrial sectors have highly attractive incentives, including 40% accelerated tax depreciation under Section 32 of the Income Tax Act in Year 1, along with custom commercial net-metering engineered by Deb Solar's licensed electrical contractors.

You only need your latest WBSEDCL electricity bill, Aadhaar card, bank account details (cancelled cheque or bank passbook copy for DBT transfer), and proof of roof ownership. The Deb Solar engineering desk handles all portal documentation, uploading, and liaison on your behalf with zero hassle.

The subsidy amount is generally credited directly into the beneficiary's bank account within 30 days of submitting the net-meter commissioning report and PCR certificate on the National PM Surya Ghar portal.

Approximately 240 to 300 square feet of shadow-free roof area is required for a 3 kW to 3.2 kW solar plant. It should ideally face south for optimal solar radiation. With Deb Solar's elevated pergola walkway structures, you also retain 100% usable, walkable roof space underneath for family use and rooftop gardens.

Standard grid-connected on-grid solar systems automatically disconnect during an electrical grid outage for utility worker safety (anti-islanding protection). If you require uninterrupted power backup during grid power cuts, Deb Solar can engineer a hybrid solar system with dedicated lithium or tubular battery backup.

Yes, high-efficiency Mono PERC and TopCon solar modules continue to generate power on cloudy days utilizing diffused ambient sunlight, operating at approximately 20% to 30% of peak capacity. Any momentary deficit is automatically and seamlessly drawn from the WBSEDCL grid through your bidirectional net meter.

Once site approvals are secured, the physical rooftop mounting and electrical cabling of your solar plant takes just 1 to 2 days. The entire end-to-end process — including WBSEDCL inspection, bi-directional net-meter changeover, and commissioning certificate upload — typically takes 2 to 4 weeks.

Tier-1 solar PV modules come with a 25-year linear performance warranty guaranteeing over 80% to 84% output efficiency. Smart grid-tie inverters include a 5 to 10-year manufacturer replacement warranty, and Deb Solar provides comprehensive structural and electrical workmanship guarantees.

Rooftop solar systems require virtually zero mechanical maintenance because they contain no moving parts. You only need to rinse the panels with clean water once every 10 to 14 days to wash away atmospheric dust and bird droppings to keep energy yields maximized.

No, absolutely not. We use non-penetrating counter-weighted concrete anchor pedestals or chemical anchor fasteners with heavy-duty EPDM isolation gaskets. No drilling ever compromises your roof's waterproofing membrane. In fact, the elevated solar canopy acts as an umbrella, shielding your concrete slab from harsh summer ultraviolet heat and torrential monsoon rains, which actually extends your rooftop slab's lifespan.
