Amaphaneli elanga asophahleni anganikeza amandla ahlanzekile, avuselelekayo endlini noma esakhiweni, anciphise ukuthembela emithonjeni yamandla evamile, ehlise izindleko zamandla, futhi abangele ukungcoliswa okuncane kwemvelo.Kodwa-ke, lapho ukhetha futhi ufaka ama-solar panels ophahleni, izici ezifana nesakhiwo sophahla, i-orientation, kanye ne-shading zidinga ukucatshangelwa ukuze kuqinisekiswe ukusebenza kahle kwesistimu nokuphepha.
