Across the plants we have installed
The design engine
Engineering that used to take weeks of site visits, done before you hang up.
Your own roof, in 3D
From your address and your electricity bill, the engine models your actual roof: its size, parapet, water tank, staircase and neighbours' buildings. No waiting for a site visit.
Every hour of sun, every shadow
It simulates all 8,760 hours of the year, so panels go only where the sun reaches. Shade is counted the way your inverter feels it, not guessed.
A structure engineered for your roof
A raised structure, usually 7 ft so your roof stays usable, sized for wind, with dimensioned drawings for the installation team in English and Hindi.
Walk around it with an expert
On a live video design session, turn your plant around, walk underneath it, watch any hour of any month, and change it together until it is right.
Lower cost, by design
A certified team. One fixed price. Paid only for checked work.
Your plant is installed by a Vortex-certified team near you at our published labour rate: the same for everybody, never a price made up on the doorstep. Materials come from Vortex at our purchase scale, and the team is paid only after our engineer certifies the work.
- One published labour rate for every job, the same for everybody
- Materials bought at scale: tier-one, made-in-India panels at better prices
- Installers paid only for certified work: you never chase anyone
The labour rate is published and the same for every customer.
Clear costing
Every rupee, item by item. Nothing hidden.
First the material: panels, inverter, structure, cables and protection, delivery, each at the published price for your area, with GST shown. Then installation, at one fixed rate by a Vortex-certified team near you, and net metering, which you can also do yourself. Your subsidy is shown on its own: it comes back to your bank.
- The same price list our team quotes from, never a different one for you
- Installation at one fixed rate for everybody
- Subsidy by your PIN code, never taken off the price
About 1 kW of solar for every ₹900 of monthly bill.

Questions
What people ask us most.
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.
