Frequently asked questions
Which is the best rooftop solar installer in Kolkata?
"Best" depends on your roof size and budget — but a workable shortlist is the top 3 installers above by Google rating and review count, then ask each for a written quote covering panel make (Tier-1 only), inverter brand, structure type, BoS, and warranty terms. Verified phone numbers above let you call directly; reputable installers will do a free site survey in Kolkata before pricing.
How much does rooftop solar cost in Kolkata?
A 3kW residential system in Kolkata typically runs ₹1.6-2.2 lakh before subsidy, ₹85k-1.4 lakh after PM-Surya Ghar (₹78k subsidy). 5kW systems land around ₹3 lakh net. Payback at current West Bengal tariffs: 4-6 years.
Does my electricity board support net-metering?
Yes — all West Bengal DISCOMs are mandated to offer bi-directional net-metering for residential rooftop solar under MNRE guidelines. The installer handles meter swap + DISCOM paperwork (typically 2-4 weeks).
How long does installation take?
Once site survey + approvals are done, a 3kW system installs in 2-3 days, 5kW in 3-5 days. Total timeline from booking to commissioning is typically 4-8 weeks in Kolkata, mostly waiting on DISCOM net-meter approval.
Can I get a loan or EMI for rooftop solar in Kolkata?
Yes. Most public-sector banks (SBI, Canara, BoB) and several NBFCs offer solar loans covering 80-90% of system cost at 8-11% interest, 5-7 year tenure. Many installers in Kolkata also have tie-ups with financing partners and can process the loan alongside the PM-Surya Ghar subsidy paperwork. Ask the installer to quote both cash and EMI prices.
