The People Behind Heliostrom
PonnalKeppan
Strategy · Business Development · Customer Relationships
PonnalKeppan leads Heliostrom's growth and client relationships. Over a decade in Tamil Nadu's energy space taught him to see solar from the customer's side first — which is exactly why Heliostrom has a 5.0 Google rating built on follow-through, not marketing.
"Most people who call us are not sure if solar is right for them. My job is to give them an honest answer — even if that answer is wait six months. That honesty is what makes people come back and refer their neighbours."
Viveak
Engineering · Installation Quality · Technical Operations
Viveak oversees all engineering and installation quality at Heliostrom. He set the standard early — Tier-1 panels only, engineer sign-off on every job, no compromise on wiring or structure. His philosophy: every system should be designed for 25 years, not just the commissioning day.
"A badly installed 10kW system is worse than no system at all. We take time to get the engineering right — the roof structure, the cable routing, the earthing, the inverter placement. Everything has a reason."
What We Stand For
A Tamil Nadu where every home and business that can go solar, has gone solar — with a system that performs for 25 years. Solar adoption here is far below what is possible. Heliostrom exists to fix that.
Install solar that genuinely cuts electricity costs — with transparent pricing, quality engineering, and support long after commissioning.
Honesty Before Sales
If solar does not make sense for you, we tell you.
Engineering First
Every system by a qualified engineer. No templates.
Lifelong Support
Our relationship does not end at commissioning.
Tamil Nadu Roots
Chennai company. We know the local grid inside out.
