REC has developed a new series of residential heterojunction solar panels with efficiencies ranging from 20.6% to 22.2% and an operating temperature coefficient of -0.24% per degree Celsius.

Singapore-based PV module manufacturer REC has developed residential solar modules based on its Alpha heterojunction cell technology.

“Production has started at REC’s Industry 4.0 fab in Singapore and first shipments will reach the US market in May 2024,” the company said in a statement released.

The REC Alpha Pure-2 Series is available in four versions, with power ratings ranging from 400 W to 430 W, and efficiencies of 20.6% to 22.2%. They are made with 132 heterojunction, half-cut monocrystalline solar cells and have a maximum system voltage of 1,000 V.

The solar modules have open-circuit voltages ranging between 48.5 V and 49.3 V, along with short-circuit currents ranging from 10.60 A to 10.81 A. All…
