About EFS Group

EFS Revision Energy Sdn Bhd, trading as EFS Group, is a Malaysian clean energy and EPCC company based in Petaling Jaya, Selangor, with additional offices it lists in Penang, Johor and Sarawak. Its website describes end-to-end EPCC (engineering, procurement, construction and commissioning) services for solar PV and battery energy storage systems, covering residential, commercial, industrial and utility-scale (large-scale solar) projects, alongside EV charging and long-term operations and maintenance.

EFS Group's website says it has delivered more than 300 MWp of solar capacity across Malaysia to date, without breaking this down by individual project. Its projects page names clients including Chong Hwa Independent High School, Barry Callebaut Malaysia, Koito Malaysia, NGK Electronics Devices (M), NJRP (M) and Precast Concrete (Pontian), alongside projects in Thailand. Client testimonials on its site also name Billion Group, Cheng Hua Engineering Works and Supercomnet Technologies Berhad, without stated capacities or dates for any of these.

EFS Group's website covers Solar ATAP, Malaysia's current rooftop solar scheme, alongside its EPCC, BESS and EV charging services. Its FAQ page cites a benchmark of RM 3,000–4,000 per kWp for a fully installed system, RM 15,000–35,000 all-in for a landed residential system, and about 5 to 7 m² of roof space needed per kWp. It doesn't name specific panel or inverter brands, or publish warranty terms, on its website.
