Households from 3.3 kW to 5+ kW, farms, shops and factories — supplied and installed by Rayantra, with a 25-year warranty on every panel.
Pick the closest amount. We’ll show the solar system that fits your home — no technical knowledge needed.
kW is simply the size of your solar system. A bigger bill needs a bigger system.
Indicative estimate: ~₹6 per unit, ~4 units per kW per day, 550 W panels. *Units generated by the recommended size. †PM Surya Ghar, subject to scheme rules and eligibility. Real figures depend on shade, tilt and orientation.
Rayantra supplies and installs directly — no handoff to a separate contractor partway through.
