Our approach
Start with site data, design before procurement, build to the design, verify at commissioning and maintain afterwards. Each stage is documented so decisions can be traced.
About us
A Chennai solar EPC company built around engineering
GLS Energies Solutions delivers solar power systems end to end — design and engineering, procurement, installation, commissioning and long-term maintenance — for residential, commercial, industrial and institutional customers.
Company overview
Who we are
GLS Energies Solutions is a solar EPC provider based in Pallavaram, Chennai, with over ten years of experience and more than 300 completed projects. We cover on-grid and off-grid systems, rooftop and ground-mount installations, MW-scale EPC works, solar water pumping, solar street lighting and ongoing operation and maintenance.
Our work spans the full lifecycle of a solar asset. Before any capacity is proposed we study consumption, tariff category, roof or land condition, shading and existing electrical infrastructure. After commissioning we stay involved through maintenance and performance review, because generation that is never checked quietly declines.
We keep claims to what we can support. Where a figure depends on a manufacturer datasheet, a utility policy or site measurement, we say so and share the source rather than rounding it into a marketing number.
