Solar energy company REC recently launched its latest high-efficiency residential solar panel as part of its award-winning REC Alpha series.

The new REC Alpha Pure-R features heterojunction (HJT) cells in the large G12 format as part of a patented panel design, and delivers power output up to 430Wp.

The REC Alpha Pure-R module size is less than two square metres, making it ideal for residential installations where space is limited. G12 solar panels are mainly used in commercial and utility installations, but the compact design of the REC Alpha Pure-R makes it suitable for this technology to be used for residential rooftops.

“The REC Alpha Pure-R really hits the sweet spot in terms of its size, weight, power output and handling,” says Jan Enno Bicker, CEO, REC Group.

“With the new panel, we have managed to pack more power into a compact panel size, enabling homeowners to be more energy independent.”

The new solar panel comes with a nine-amp current, making it compatible with various modern MLPE devices, and gives installers more system design options to maximise power for homeowners.

Another new feature is the four-part junction box which takes REC’s existing Twin Design a step further, dividing the panel into four strings and reducing the size of sections that switch off in shaded conditions. Therefore, the panel can generate more energy when partially shaded.

The lead-free REC Alpha Pure-R comes with a leading power density of 223W/m2 and can be easily handled by installers. Building on the success of the REC Alpha and Alpha Pure series, the new panel features 80 half-cut HJT cells in a gapless cell layout.

The advanced cell-connection technology improves the current flow and eliminates invasive soldering, adding to the high-efficiency and long-lasting performance.

The low temperature coefficient keeps the solar panel running efficiently, even on hot days, making it ideal for warm climates and generating as much energy as possible on sunny days.

The 30mm frame with its two support bars ensures each panel can withstand heavy loads – up to 7000 pascal snow load and up to 4000 pascal wind load.

The REC Alpha Pure-R is scheduled to start production in August 2022 at REC’s new production lines in Singapore, doubling REC’s Alpha product line capacity from 600MW to 1.2GW.
