From rooftop to megawatt.

Rooftop solar uses your existing roof space and suits most homes, schools, hospitals and factories with adequate structural capacity. Ground-mounted solar sits on open land and works best for larger industrial loads or where roof space runs out — Precot Mills' 4 MW plant in Pollachi is ground-mounted for exactly this reason. We assess your site and recommend whichever gets you to your energy target faster.

As a rule of thumb, 1 kW of solar needs roughly 70–100 sq ft of usable, shadow-free area. A typical home system (3–8 kW) fits comfortably on most rooftops; industrial rooftop or ground-mounted plants scale up from there. We confirm the exact number after a site visit, since shading, orientation and structural load all affect the final layout.

It varies by scale. Residential systems typically pay back in 4–6 years, commercial rooftop in 3–5 years, and industrial or ground-mounted plants — where usage and savings are highest — often pay back in 3–4 years. After that, the electricity is essentially free for the remaining 20+ years of the system's life.

Yes, entirely. Altus is a one-stop partner — we handle the government paperwork, subsidy applications and net-metering clearances on your behalf, so you don't have to navigate utility processes or documentation yourself.

Yes, most certainly. Solar integrates cleanly with diesel generators and existing captive power setups — the system is designed to prioritise solar generation first and fall back to your existing supply automatically, with no disruption to operations.

You get live visibility into your system's daily performance through our monitoring app, plus dedicated O&M support for the life of the plant. If output ever dips below expectation, our team is alerted and dispatched — often before you'd notice it yourself.
