On-grid solar systems with net metering
Most Kolkata homes choose on-grid systems because CESC and WBSEDCL allow net metering, so surplus units can be exported to the grid.

PM Surya Ghar subsidy application support
Local installers help you apply on the National Portal, select a vendor, and claim the central subsidy of up to ₹78,000 for a 3 kW system.
-
Commercial and industrial solar installations
For shops, offices, and warehouses in mixed-use areas like Howrah or Kasba, installers design larger rooftop or ground-mounted systems.
Where rooftop solar makes the most sense in Kolkata
Affluent residential pockets like Ballygunge, Alipore, and Salt Lake City see the strongest interest because of larger terraces and higher electricity bills. New Town and Rajarhat have many new apartment complexes with flat roofs that can support shared solar for housing societies. Older neighbourhoods like Jadavpur, Behala, and Dum Dum have independent houses where a 2 kW or 3 kW system fits easily on the terrace.

Summer demand and solar output in Kolkata
Electricity consumption across India grew 8.9% in April 2026 as summer conditions progressed. In Kolkata, that means higher bills during the hot months, which is when many households start comparing solar quotes. A 3 kW system can generate more than 300 units a month on average, helping offset the extra load from fans and air conditioners.
