Rooftop Solar Installation in Velachery: Cost, Subsidy & Installers

Updated September 2026 · By Arka Solar Energy · 7 min read

Planning to go solar in Velachery? Whether you're in an independent home near Vijayanagar, an apartment off the 100 Feet Road, or a villa toward Pallikaranai, rooftop solar is one of the smartest ways to cut your TANGEDCO bill. This guide covers what it costs in Velachery, the subsidy you can claim, your realistic savings, and how the installation actually works.

Quick answer: A 3kW rooftop solar system in Velachery costs about ₹1,80,000–₹2,10,000 before subsidy and ₹1,02,000–₹1,32,000 after the ₹78,000 PM Surya Ghar subsidy — saving a typical home ₹2,500–₹3,800 a month and paying for itself in 3–4 years.

Why Velachery Homes Are Going Solar

Velachery is one of Chennai's most densely populated residential hubs, with a mix of independent houses, gated communities, and apartment blocks — most of them facing steadily rising electricity bills as air-conditioning use climbs through Chennai's long summers. The area gets strong, consistent sunlight year-round, which makes rooftop generation reliable. Combined with the central subsidy and TANGEDCO net metering, that turns an unused roof into 20+ years of near-free power.

Subsidy for Velachery Homeowners

Residents qualify for the central PM Surya Ghar: Muft Bijli Yojana subsidy — ₹30,000 per kW for the first 2kW and ₹18,000 for the third kW, capped at ₹78,000 for systems of 3kW and above. The subsidy is credited directly to your bank account after installation and inspection. We handle the entire application on the PM Surya Ghar portal and the TANGEDCO net-metering approval so you don't have to navigate the paperwork. Full details in our PM Surya Ghar application guide.

How Much Can You Save in Velachery?

Savings depend on your consumption and roof, but a correctly sized system can bring your energy charges close to zero. A typical 3 BHK Velachery home using ~450 units a month cuts a ₹3,400 bill down to just fixed charges — saving roughly ₹33,000–₹36,000 a year.
