Two 3kW quotes from two different vendors can differ by tens of thousands of rupees, and the reason usually isn't one vendor overcharging — it's that "3kW system" doesn't specify panel technology, inverter type, or mounting complexity. This page explains what actually drives the price, so a quote makes sense rather than reading as a single unexplained number.
For the same system size, these choices change the final number more than anything else:
Roof area and panel count both scale roughly linearly with system size (using common ~540W panels, about 100 sq ft per kW). Browse each size below for who it typically suits and estimated monthly generation.
A free site survey lets us measure your roof, review your electricity bills, and give you a written quote covering exactly what's included — panels, inverter, mounting, cabling, installation and commissioning — with no line items added after the fact.
Cost depends on system size, panel technology and brand. See our Solar Panel Price in Kanpur guide for indicative ranges from 1kW to 10kW, or contact us for an exact written quote after a free site survey.
