I-solar monocrystalline silicon amamojula we-PERC anohlangothi olulodwa enziwe ngezinto ze-silicon ze-monocrystalline, ezinokusebenza okuhle kakhulu kokuguqulwa kwe-photoelectric futhi angaguqula ukukhanya kwelanga kube amandla kagesi.Inezici zokukhiqiza amandla ohlangothini olulodwa, uhlangothi olulodwa kuphela lokuguqulwa kwe-photoelectric, kanti olunye uhlangothi luvame ukumbozwa ngezinto zensimbi noma zengilazi.
