Rooftop solar is gaining traction among commercial and industrial consumers as businesses look to use existing factory space to cut electricity costs and reduce dependence on grid power.

Germany-based KHS Machinery (KHS Group), an industrial equipment manufacturer, is expected to save ₹7.7 million (~$80,726.8) annually after installing a 750.2 kW rooftop solar project at its facility in Nandej, Gujarat.

KHS manufactures filling and packaging systems for the beverage industry.

The company now meets 60-65% of its power needs through the rooftop solar system.

The rooftop solar project is expected to generate nearly 1.1 million units of electricity annually, with average daily and monthly generation of approximately 3,000 kWh and 90,000 kWh, respectively.

The rooftop solar system is expected to yield a payback within three years.

The project was commissioned by Gujarat-based rooftop installer, Malibu Renewables, in February 2026.

The rooftop system uses Rayzon Solar’s 550 Wp Mono PERC bifacial solar modules and five units of 125 kW Polycab’s inverters.

KHS Machinery opted for a rooftop solar installation as it enabled the company to use its existing infrastructure without the necessity of using additional land.

The company said it plans to expand its rooftop solar capacity and might evaluate installing a battery energy storage system if current solar generation does not meet its needs.

Malibu Renewables, which executed the project, said the installation presented engineering challenges as it was carried out on an exposed truss structure. The project required installation on column-less structures and the erection of floating walkways to ensure no additional weight was added to the roof.

Malibu Renewables also commissioned a 3 MW rooftop solar project for Maharashtra-based textile fabric manufacturer G.M. Syntex in February this year.
