Our Roots

Bangalore roots. National trust.

We’re not just another solar company. Atria is part of Bangalore’s growth story — the team behind ACT Fibernet, and contributors to iconic projects like Chinnaswamy Stadium and several hydro projects in Karnataka, including plants in Shimsha, Shivanasamudram, and Krishna Raja Sagara.

With a heritage spanning over five decades, we’ve quietly powered progress in this city. Now, we’re helping homes go solar with the same care and engineering excellence.

Why We Exist

Clean power, without compromise.

Solar shouldn't mean guesswork, hidden costs, or a system you stop trusting after year one. We build the opposite.

Our Mission

Put reliable, honestly-priced rooftop solar on every Indian home — engineered to perform for decades, backed by people who answer the phone long after the install is done.

Our Vision

A Bengaluru — and a country — where going solar is the obvious, easy choice: transparent, fast, and built on 50 years of engineering trust rather than sales pressure.

What We Stand For

The principles behind every install.

🛠️

Engineering first

DCR-certified panels, IIT-certified structures, and specs we publish openly. Decisions are made by engineers, not by whatever's cheapest that week.

🔍

Radical transparency

What we quote is what you pay — cables, earthing and all. No hidden line items, no surprise add-ons at the door.

⏳

Built to last

A 5-year workmanship warranty and 5 years of no-cost quarterly maintenance. We plan for year 25, not just handover day.

📍

Local & accountable

Bengaluru roots, local crews, and real people you can reach. When something needs attention, we're already down the road.

⏱️

Respect your time

Most installs finish in about five hours with same-day commissioning. Pre-planned logistics, zero mess left behind.

🌱

Cleaner by default

Every rooftop we power cuts grid load and carbon. Good for your bill, and for the city we all share. Every install is one more home off fossil-fuel power.

By The Numbers

A track record, not a pitch.
