What is different about selling solar in West Bengal
West Bengal's defining constraint is resource, not regulation: at roughly 4.7 kWh/m²/day it has the lowest usable irradiance among India's major solar states, and with a heavy June-September monsoon a system here needs a visibly larger array than a Rajasthan equivalent to deliver the same annual units. Kolkata and Howrah fall under CESC rather than WBSEDCL, so the licensee — and therefore the portal, the meter and the inspection process — is decided by address. CESC's comparatively high retail tariffs partly offset the weaker generation, which makes commercial rooftops in the Kolkata metro a better payback story than the irradiance figure alone suggests.

WBSEDCL covers most of the state while CESC Ltd is the licensee for Kolkata and Howrah, each administering net metering under WBERC regulations through separate application processes.
Net metering in West Bengal
Regulator: West Bengal Electricity Regulatory Commission (WBERC) / WBREDA
Needs verification
Rooftop solar in this state is connected under the state electricity regulatory commission's net-metering regulations: the installer files an application with the local DISCOM, the DISCOM sanctions feasibility against the consumer's sanctioned load, the plant is installed by an empanelled vendor, and a bi-directional meter is installed after inspection before commissioning and credit settlement begin. Exact load caps, capacity ceilings, settlement period and fee schedule must be confirmed against the current DISCOM circular before quoting.
PM Surya Ghar subsidy in West Bengal
Needs verification
PM Surya Ghar: Muft Bijli Yojana is a central (all-India) scheme, so residential consumers in this state are eligible on the same national basis, applying through the National Portal and a state-empanelled vendor, with the subsidy released to the consumer's bank account after installation and DISCOM inspection. Current slab amounts, any additional state top-up, and the state nodal-agency workflow must be verified before being shown to a customer.
Applications in West Bengal route through West Bengal Renewable Energy Development Agency (WBREDA). The exact slab maths — ₹30,000/kW for the first 2 kW, ₹18,000/kW for the third, capped at ₹78,000 — is worked through in our PM Surya Ghar subsidy guide.
