Ka whakamahia ēnei whati hiko hei tiaki me te whakahaere i te au nui rawa i roto i ngā pūnaha rokiroki pākahiko photovoltaic solar me ngā hiko DC. Kei te wātea ēnei i roto i ngā momo au kua whakatauria pērā i. Ko ngā whati hiko DC e whakaaetia ana kia whakaritea ka whakarato i ngā mahi mō te whakakore hiko, te tiaki i te hiko poto, te whakatikatika, me te tiaki, ka roa ake te roa o te ora o ngā taputapu hiko. Ka tiakina e rātou ngā taputapu hiko mai i ngā kino i puta mai i te taumaha rawa, te hiko poto, me ētahi atu hapa hiko.
