Solar for homes
A power plant on your roof, built around your family.
On-grid rooftop solar from 2 kW to 10 kW, designed in 3D on your own roof in minutes, installed by a Vortex-certified team at our published rate, with the PM Surya Ghar subsidy and net metering done for you.
How an on-grid plant works
Panels make DC electricity; the inverter turns it into the AC your home uses. Your home uses solar first. What is left flows to the grid and your net meter counts it; at night you take units back. You pay only for the difference, and extra units carry forward.
No batteries means no battery to replace every few years: an on-grid plant needs only a wash with plain water every two weeks.
What goes into your plant
Panels
DCR (made-in-India cells) panels from tier-one makers, as PM Surya Ghar requires, with a 25-year performance warranty.
Inverter
A grid-tied inverter sized to your plant, with Wi-Fi monitoring so you and we see every unit it makes.
Structure
Hot-dip galvanised structure, raised so your roof stays usable, angled to the south for the most sun.
Safety
AC and DC distribution boxes, surge protection, earthing and lightning arrester, to the DISCOM's standards.
How big a plant do you need?
Roughly 1 kW for every ₹1,000 of your monthly bill. Each kW makes 4 to 5 units a day in Lucknow and needs about 70 sq ft of shade-free roof.

Free for the first 5 years, then on a low-cost care plan. If your plant slows or stops, we know before you do, and help is on its way.
About 70 sq ft of shade-free roof per kW: a 3 kW plant needs about 210 sq ft, a 5 kW plant about 350 sq ft. A south-facing, shadow-free roof is best; your 3D design shows exactly what fits on yours, in minutes.
Under PM Surya Ghar Muft Bijli Yojana the central government gives ₹30,000 per kW for the first 2 kW and ₹18,000 for the third: up to ₹78,000 for homes. Uttar Pradesh adds up to ₹30,000 more. We file it all for you; it is paid straight into your bank account.
Your panels make electricity in the day. Your home uses it first; what is left goes to the grid and the net meter counts it. At night you take from the grid. You pay only for the difference, and extra units carry forward.
An on-grid plant switches off during a power cut, for the safety of linemen working on the wires, and starts by itself when power returns. If you need backup, ask us about a hybrid system with batteries.
Panels carry a 25-year performance warranty, inverters 5 to 10 years. Clean the panels with plain water every two weeks. We watch your plant every 15 minutes (free for the first 5 years, then on a low-cost care plan) and come when something is wrong.
Yes. Banks offer solar loans at low interest under PM Surya Ghar, and we help with the paperwork. Many customers pay less in EMI than they used to pay in electricity bills.
Your design takes minutes. From booking to switch-on is usually 3 to 6 weeks: installation takes 1 to 2 days, the rest is the DISCOM's net-meter process, which we follow up every day.
Every job is installed at our published labour rate, with no middlemen in between; we buy panels and inverters at scale; and we pay installers only for work our engineer has certified, so nobody prices in risk.
Not to design it. Our engine designs your plant from your address, satellite and 3D maps and your bill, and you can walk through it with our expert on a video call. The installation team checks the roof on the day of installation.
