Lesi yisixazululo esinomnotho sokufakwa kukabakaki we-photovoltaic esifanele ophahleni lwezimboni nezohwebo. Ubakaki we-photovoltaic wenziwe nge-aluminium alloy nensimbi engagqwali, enokumelana nokugqwala okuhle kakhulu. I-angle yokufaka yamamojula we-photovoltaic inganyuswa ophahleni ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza amandla eziteshini zamandla e-photovoltaic, ezingahlukaniswa zibe uchungechunge oluthathu: 10-15 °, 15 ° -30 °, 30 ° -60 °.
