West Bengal
Independent advice for domestic WBSEDCL connections across Kolkata metro, Howrah, Siliguri, and district towns. Bay-of-Bengal weather cuts annual yield versus dry inland states — your slab bill still decides payback after central CFA.
West Bengal’s monsoon and high humidity mean lower annual kWh per kW installed than Gujarat or Rajasthan brochure numbers suggest. The decision hinge is whether your WBSEDCL bill recovers net cost after PM Surya Ghar CFA — not whether a vendor’s pan-India average slide looks good. Sealix advises; we are not WBSEDCL and not your installer. Start with the free home check.
Most West Bengal domestic homes sit on WBSEDCL (West Bengal State Electricity Distribution Company). Rooftop solar under PM Surya Ghar selects WBSEDCL on pmsuryaghar.gov.in, then follows DISCOM feasibility, net-meter installation, and commissioning steps published on the DISCOM portal.
Load enhancement may apply if applied PV capacity exceeds sanctioned load — factor any published charges into net economics.
Central residential CFA is commonly ₹30,000 / ₹60,000 / up to ₹78,000 for eligible 1–3 kW+ systems after commissioning. West Bengal state top-ups, when announced, apply only to households meeting published eligibility at commissioning — do not assume a separate state cash amount unless an official notice matches your date. Full walkthrough: PM Surya Ghar guide.
June–September cloud cover and pre-monsoon thunderstorms reduce daily generation across the state. Persistent humidity accelerates corrosion on mounting hardware and demands sensible inverter placement — not a rooftop edge exposed to driving rain. Northern Bengal (Siliguri, Jalpaiguri) sees different rainfall patterns than Kolkata — still size from annual bill units, not a pan-India “5 kWh/kW/day” marketing slide.
For Kolkata-specific terrace realities — north Kolkata shade pockets, south Kolkata bungalows, society NOC timelines: rooftop solar in Kolkata.
Grid-tied rooftop solar needs a bi-directional net meter from WBSEDCL. Settlement rules follow the WBERC tariff order in force at commissioning. National explainer: net metering in India.
Many mid-to-high bill West Bengal homes land near 3 kW to capture the full central CFA ceiling. Going to 5 kW adds capacity with no extra central CFA — see 3 kW vs 5 kW and ₹3,000/month bill guide.
