0 Solar panel e sebetsa joalo ka sesebelisoa se fetolang khanya ea letsatsi ho ba motlakase ka lisele tsa photovoltaic (PV), tse hahiloeng ka lisebelisoa tse hlahisang lielektrone tse matlafatsoang ha khanya e pepesehile. Li-electrone tsena li tsamaea ka potoloho, li etsa motlakase o tobileng (DC), o ka sebelisoang ho matlafatsa lisebelisoa kapa o bolokiloe ka libeteri. Liphanele tsa letsatsi, tseo hape li bitsoang liphanele tsa lisele tsa letsatsi, liphanele tsa motlakase oa letsatsi, kapa li-module tsa PV, li sebelisa ts'ebetso ena.
Liphanele tsena hangata li etsa li-arrays kapa litsamaiso, tse etsang sistimi ea photovoltaic e nang le liphanele tsa letsatsi tse le 'ngoe kapa ho feta, hammoho le inverter e fetolang motlakase oa DC hore e be alternating current (AC). Likarolo tse ling joalo ka lilaoli, limitara, le li-tracker le tsona e ka ba karolo ea seta sena. Litsamaiso tse joalo li sebeletsa merero e fapaneng, ho fana ka motlakase bakeng sa lits'ebetso tse kantle ho marang-rang libakeng tse hole kapa ho fepa motlakase o mongata ka har'a marang-rang, ho lumella hore ho be le mekitlane kapa litefo ho tsoa ho lik'hamphani tsa lits'ebeletso - tokisetso e bitsoang "grid-connected photovoltaic system".
Melemo ea liphanele tsa letsatsi e kenyelletsa ho sebelisa mehloli ea matla e nchafalitsoeng le e hloekileng, ho fokotsa ho ntšoa ha likhase tse futhumatsang lefatše, le ho fokotsa likoloto tsa motlakase. Leha ho le joalo, litšitiso li kenyelletsa ho itšetleha ka ho fumaneha ha khanya ea letsatsi, ho hloka ho hloekisoa nako le nako le litšenyehelo tse ngata tsa pele. E sebelisoa haholo libakeng tsa bolulo, tsa khoebo le tsa indasteri, liphanele tsa letsatsi le tsona li bohlokoa sebakeng le lits'ebetsong tsa lipalangoang.
