REC has unveiled the Alpha Pure-R all-black heterojunction panel delivering a power output of up to 430 Wp. Packed with a high power density (223 watts/m²), the panel generates more energy from the same area and is ideal for residential installations, where space is limited.

The RoHS-compliant panel is built with 80 half-cut HJT cells and measures less than 2 square meters in size. It has 3.2 mm anti-reflective solar glass, a highly resistant black polymer backsheet, and a black anodized aluminum frame.

REC has also unveiled TwinPeak 4 series monocrystalline silicon solar panels for residential and commercial rooftops in India.

These panels are available in power outputs ranging from 360 W to 375 W, with efficiencies between 19.7% and 20.5% under standard temperature conditions. The respective open-circuit voltage is 40.6 V to 41.2 V, and short-circuit current is 11.26 A to 11.45 A.

Each panel is built with 120 monocrystalline silicon p-type half-cells. It comes with 3.2 mm anti-reflective solar glass, a highly resistant polymer backsheet, and an anodized black aluminum frame.

The module can operate with a maximum system voltage of 1,000 V and in temperatures ranging from -40 to +85 degrees Celsius. It has dimensions of 1,755×1,040×30 mm and weighs 20 kg.
