About Us — Trusted Renewable Energy Venture

Quick overview: Founded in 2013 in Chathannoor, Kollam, Sonetec Powers is South Kerala's trusted clean-energy venture approved by ANERT, empanelled with MNRE for the PM Surya Ghar scheme, and accredited by KSEB for grid net metering. With over 1,200 rooftop solar installations, 10,000+ biogas units, and local branch offices in Chathannoor, Anchal, and Chadayamangalam, we provide turnkey engineering, government subsidy processing, and lifetime after-sales support across Kollam, Thiruvananthapuram, Pathanamthitta, and Alappuzha.

Our Story

Sonetec Powers started in 2013 with a mission to provide green and clean energy across South Kerala. From our head office near LM Mall, Chathannoor, we now serve four districts with branch offices in Anchal and Chadayamangalam.

We partner with government-approved programmes to deliver subsidised solar at market-leading quality — and we've expanded into biogas, waste management, and backup power solutions trusted by thousands of Kerala families and businesses.

What We Do Today

From a single office near LM Mall in Chathannoor, Sonetec Powers has grown into a full-service renewable energy company covering four districts of South Kerala. Our team designs and installs rooftop solar — on-grid, hybrid and off-grid — handles PM Surya Ghar subsidy paperwork, and commissions KSEB net meters.

Beyond solar, we are one of the region's most experienced biogas installers with 10,000+ projects, and we supply complete waste management solutions including biobins, compost systems and institutional incinerators. Our product division stocks Luminous and leading tier-1 inverters and batteries with local after-sales support.

We believe every customer deserves honest advice — right-sized systems, transparent quotes, and no pressure. That approach has kept us in business since 2013 while larger national installers come and go.
