Regitec PV modules in the catalogue: a pallet of 36 modules at 470W N-Type TOPCon, bifacial double glass, for a total of 16.92kWp.
470W in double glass is a handy size for medium to large homes: twelve modules clear 5.6kWp, the usual power to pair with a 5 or 6kW single-phase inverter, without going into formats over two metres long that are awkward to handle on a pitched roof.
Bifacial pays off mainly on a flat roof or ground mount with a light surface under the modules; on a pitched roof the gain from the back is marginal, but dual glass still helps the life of the module.
