How Much Does Solar Panel Installation Cost in West Bengal? (2026 Price Breakdown)
“How much will this actually cost me?” is the first question every homeowner asks before going solar — and fair enough, since most quotes online are vague ranges that don’t account for subsidy, roof type, or what you’re actually trying to save on your bill. Here’s a straight, current breakdown of solar panel installation cost in West Bengal, plus a way to get your own exact number in under a minute. Cost by System Size (Before and After Subsidy) Prices vary by brand, panel technology, and installer, but here’s the realistic 2026 range for a standard on-grid rooftop system: System Size Cost Before Subsidy PM Surya Ghar Subsidy Cost After Subsidy 1 kW ₹60,000 – ₹85,000 ₹30,000 ₹30,000 – ₹55,000 2 kW ₹1.1 – ₹1.5 lakh ₹60,000 ₹50,000 – ₹90,000 3 kW ₹1.5 – ₹2.1 lakh ₹78,000 ₹72,000 – ₹1.3 lakh 5 kW ₹2.5 – ₹3.5 lakh ₹78,000 ₹1.7 – ₹2.7 lakh 10 kW ₹5 – ₹6.5 lakh ₹78,000 ₹4.2 – ₹5.7 lakh For most homes in Kolkata and Howrah with a monthly bill in the ₹2,500–₹4,000 range, a 3 kW system tends to be the sweet spot — it covers a typical household’s daytime load and qualifies for the full ₹78,000 subsidy under PM Surya Ghar Yojana, which we’ve broken down in detail in our West Bengal solar subsidy guide.

Costs People Often Forget to Budget For A few smaller costs sit outside the headline system price and catch people off guard if they’re not planned for: Financing Options If You’d Rather Not Pay Upfront Several public sector banks offer collateral-free solar loans starting around 7% interest, specifically for PM Surya Ghar-linked installations. This spreads the post-subsidy cost into manageable EMIs rather than a single lump sum — worth asking about if the ₹1.3–2.7 lakh range above is more than you want to pay at once.
