ʻO nā panela lā nā mea hana e hoʻololi i ka lā i uila ma o ka hoʻohana ʻana i nā pūnaewele photovoltaic (PV). Hana ʻia nā pūnaewele PV me nā mea e hoʻohua ai i nā electrons hauʻoli ke ʻike ʻia i ka mālamalama. Holo nā electrons ma ke kaapuni a hoʻopuka i ka uila pololei (DC), hiki ke hoʻohana ʻia no ka hoʻohana ʻana i nā mea like ʻole a mālama ʻia paha i loko o nā pihi. Ua ʻike ʻia nā panela solar he panel cell solar, panel electric solar, a i ʻole PV modules. Hiki iā ʻoe ke koho i ka mana mai 5W a 550W.
ʻO kēia huahana he module solar. Manaʻo ʻia e hoʻohana ʻia me nā mea hoʻokele a me nā pā. He nui nā noi o nā panela solar a hiki ke hoʻohana ʻia ma nā wahi he nui, e like me nā hale, nā hoʻomoana, nā RV, nā moku moku, nā kukui alanui a me nā wahi mana o ka lā.
