Rooftop Solar in Kolkata, Howrah and Hooghly: 7 Myths vs Facts
Rooftop solar in Kolkata, Howrah and Hooghly: 7 myths vs facts on monsoon output, CESC/WBSEDCL net metering, old roofs, flats and factories.
Rooftop Solar in Kolkata, Howrah and Hooghly: Myths vs Facts
Quick answer: Yes, rooftop solar works well in Kolkata, Howrah and Hooghly. Monsoon clouds lower output on some days, but the system still generates through the year, and both CESC and WBSEDCL consumers can use net metering and apply for PM Surya Ghar on the official portal.
Homeowners, flat owners and factory owners across Greater Kolkata ask the same questions again and again: is our weather good enough, does CESC allow solar, and can old buildings take the load? Here are the common local myths with the facts. For the full list of national solar myths, see our Solar Myths vs Facts page.
Myth 1: Kolkata is too cloudy and humid for solar
Fact: Solar panels need daylight, not heat. On heavy monsoon days generation drops, but panels still work on diffuse light, and the long sunny spells from October to May make up for it. What matters most is a shade-free roof, the right tilt and regular cleaning, because dust and soot reduce output more than humidity does.
Myth 2: Solar is not allowed for CESC consumers
Fact: Kolkata and parts of Howrah, Hooghly and the 24 Parganas are supplied by CESC, while most of the rest of West Bengal is supplied by WBSEDCL. Both offer net metering for grid-connected rooftop solar. The paperwork and timelines differ, which we compare in CESC vs WBSEDCL net metering for Kolkata and Hooghly.
Myth 3: PM Surya Ghar is only for villages or other states
Fact: PM Surya Ghar: Muft Bijli Yojana is a national scheme for residential consumers. Homes in Kolkata, Howrah and Hooghly apply on pmsuryaghar.gov.in by selecting West Bengal and their DISCOM. Under the scheme, SolarConnect India installations are done by the SolarConnect team together with the registered vendor, Pro Power Energies.

Myth 4: Old North and Central Kolkata buildings cannot take solar
Fact: Many older buildings can, but the roof must be checked first. A site survey looks at slab condition, cracks, waterproofing and parapet height. If repairs are needed, finish them before installation. Raised structures also keep the roof under the panels easy to clean and drain.
Myth 5: Cyclones and storms will blow the panels away
Fact: Kolkata falls in a high basic wind-speed zone under IS 875 (Part 3), so the mounting structure must be designed for strong wind, with proper anchoring or ballast and corrosion-resistant (galvanised or aluminium) parts for the humid climate. Ask your installer how the structure is rated for wind before you sign.
Myth 6: Flat owners in apartments cannot go solar
Fact: Apartment buildings can install solar on the common roof through the housing society or RWA for common loads. See our guide on rooftop solar for housing societies and apartments.
Myth 7: Factories in Howrah and Hooghly cannot use their tin-shed roofs
Fact: Industrial belts in Howrah and Hooghly have large metal-sheet roofs that are well suited to commercial solar when the structure is fixed to the purlins with sealed fasteners. Read solar on tin shed and metal roofs: myths vs facts.
