Tell us a little about your usage and roof.
Estimates only, for guidance. Your actual savings depend on TANGEDCO tariff, sanctioned load, roof orientation, and shading. We'll confirm exact figures on a free site visit.
A rooftop system isn't an abstract number. Pick a size and watch what it powers, in daytime sun, right at home.
Indicative daytime capacity for a typical Tamil Nadu home. Air-conditioning and pumps draw most, so your exact mix depends on usage. We size it precisely on a free site visit.

A family-run business since 1999. When you call in year 12, the people who built your plant are still here to pick up.
For over 20 years we've delivered solar for state and union-territory governments across India, including some of the most remote and demanding terrain in the country.
From a 1.5 MW plant in the Lakshadweep Islands to the hills of the Northeast: if solar can be built there, we've built it.
YanSun (previously Millenium Synergy Pvt Ltd) began in 1999 in Chennai with a simple conviction: that India's future would be powered by the sun. Under the leadership of our founder, T.V. Sudhakar, what started as a small engineering venture has grown into one of the region's most experienced solar companies, with projects spanning the mainland, the Northeast, and the remote islands.
His expertise in change management, renewable energy, and engineering has guided every project we've delivered, from a single rooftop to megawatt-scale plants in places few others would attempt.
Founded in Chennai to help move India toward clean energy.
Grew across India and into South-East Asia, including government projects.
A consumer-focused solar brand bringing industrial-grade performance to every customer.
Here's exactly what going solar with us looks like, step by step. We handle the technical and paperwork heavy-lifting; you watch it come together.
A free site visit. We assess your roof, shading, and electricity usage in person.
We size the system to your needs and share a clear quote, costs, and savings.
We file your PM Surya Ghar subsidy and net-metering, then our own team installs.
The utility installs your bi-directional meter and your system goes grid-tied.
Your roof starts generating. We monitor and maintain it for the long run.
From your first call to decades of switched-on savings, here's what you get along the way, and at the very end of the journey too.
For applicable projects we design a full 3D model before a single panel goes up, so you can see exactly how your rooftop will look and generate, with no surprises on switch-on day.
It starts with a no-obligation site visit and consultation. We assess your roof, usage, and sanctioned load, then size a system that actually fits, before you commit to anything.
Questions or issues, any hour. Our team stays reachable so your system never sits waiting.
Track it all from a single app: live generation, performance, and any production issue, the moment it happens.
Solar is clean energy, and we keep it clean to the very end. When your panels finally retire after 25+ years, we take them back and handle responsible recycling, so nothing goes to waste.
From megawatt utility plants to remote island grids and rooftops on landmark buildings: a selection of what we've designed, built, and maintain.
…and over 350 more installations across 8 states and union territories.
There's more than one way to put solar on your roof. We'll walk you through the route that fits your cash flow and goals. Most homes choose to own, while businesses often weigh all three.
You fund the system once and own the asset outright. Best lifetime savings, and for homes the PM Surya Ghar subsidy brings the cost down sharply.
We build and maintain the plant on your roof; you simply buy the solar power it generates at a tariff below the grid. No capital outlay.
For megawatt needs, draw power from a dedicated off-site plant through open access, locking in long-term tariffs and deep savings on your energy bill.
