Liphanele tsa letsatsi

Sele ea letsatsi, e tsejoang hape e le "solar chip" kapa "photovoltaic cell", ke letlapa la optoelectronic semiconductor le sebelisang khanya ea letsatsi ho hlahisa motlakase ka kotloloho.Lisele tse le 'ngoe tsa letsatsi li ke ke tsa sebelisoa ka kotloloho e le mohloli oa matla.Joaloka mohloli oa matla, lisele tse 'maloa tsa letsatsi le le leng li tlameha ho hokahanngoa ka letoto, li hokahane ka ho bapisa le ho kenngoa ka thata ka likaroloana.

Solar panel (eo hape e bitsoang solar cell module) ke kopano ea lisele tse ngata tsa letsatsi tse kopantsoeng, e leng karolo ea mantlha ea tsamaiso ea matla a letsatsi le karolo ea bohlokoa ka ho fetisisa ea tsamaiso ea matla a letsatsi.
