Why Installing Rooftop Solar in Kolkata is a High-Return Investment
Grid electricity in Kolkata averages ₹7/kWh, with upper telescopic consumption tiers costing significantly more. A rooftop solar system generates clean electricity on-site at a levelized cost of only ~₹1.80/unit over 25 years.
Under the Ministry of New and Renewable Energy (MNRE) PM Surya Ghar scheme, eligible residential individual houses receive fixed financial assistance up to ₹78,000 credited directly into their bank account within 30 days of commissioning.
State Bank of India (SBI) and leading PSU banks provide collateral-free financing up to 3 kW at an attractive interest rate of 7.00% p.a. with only 10% margin money, meaning your monthly power bill savings easily cover the loan EMI.
During daytime hours, excess solar units not consumed in your home are automatically exported to the grid via bidirectional net metering. Credits appear on your bill to offset night-time consumption.
