 Product Description

REC Group 400w Mono Solar Panel - Alpha - REC405AA

REC, 400W PV Module, 1.1/1.2m (43/47”)PV Wire, MC-4, 30mm Black Frame on Black Back-Sheet, BOB, 132 Heterojunction Cells, 25A Max Fuse, 1000VDC, 381 PTC, 20/25 Standard Warranty, REC405AA

The Alpha Black module represents the cutting edge in module performance, efficiency, and aesthetics.  Alpha Black modules are assembled in Singapore with an advanced 120-cell heterojunction process, which reduces parasitic losses from cell junctions.  With HJT, REC combines the benefits of crystalline silicon solar cells with those of thin film technologies for much higher efficiency and energy yield, even at higher temperatures.

The Alpha delivers the world’s best power density on a 60-cell module, a key consideration when space is tight – like on any rooftop. With the REC Alpha Series, customers will get over 20 percent more power from the same area and the same number of panels – or, put other way, the same energy output from less space. This reduces the Balance of System (BoS) costs. In addition to better economics, customers can also look forward to an increase in the value of their property: several studies in various countries show that a premium solar installation on the roof is adding value to the property and is a highly desired extra for home-buyers, not least due to the better energy performance rating.


  • New Energy Directives - The Alpha’s industry-beating energy efficiency will make it far easier for new-build owners to meet Zero Energy performance directives like in the European Union or California, U.S.1 For a 20 kW solar installation at a multi-apartment property, for example, 70 panels with 300 Wp, or an area of 140 m2, would be required. But with the 380 Wp of the REC Alpha Series, the building would only need 50 modules, or roughly 100 m². For rooftop installations with limited available space, in particular on tower buildings in cities, high power solar panels are therefore a key enabler for these building concepts.
    REC shipments are traditionally driven by the rooftop segment, for which REC analysts expect 22% growth in 2019. The stronger push by governments for zero energy buildings in the EU, the USA (notably in California) and Japan, is expected to further fuel this market.
