Ko te whakaputa hiko photovoltaic (PV) he tukanga e whakamahi ana i te pūngao o te rā hei huri i te pūngao mārama ki te hiko. E hangai ana ki te pānga photovoltaic, mā te whakamahi i ngā pūtau photovoltaic, i ngā kōwae photovoltaic rānei hei huri i te hihi o te rā hei iahiko tika (DC), kātahi ka hurihia hei iahiko tauutuutu (AC) e te inverter ka tukuna ki te pūnaha hiko, ka whakamahia rānei hei tuku hiko tika.
I roto i ēnei, ko ngā pūtau photovoltaic te wāhanga matua o te whakaputa hiko photovoltaic o te rā, ā, he mea hanga i ngā rauemi semiconductor (hei tauira, te silicon). Ina pā te hihi o te rā ki tētahi pūtau PV, ka whakaoho te kaha photon i ngā irahiko i roto i te rauemi semiconductor, ka puta he iahiko hiko. Ka haere tēnei iahiko mā roto i tētahi ara iahiko e hono ana ki te pūtau PV, ā, ka taea te whakamahi mō te hiko, mō te rokiroki rānei.
I tēnei wā, nā te mea kei te heke tonu te utu o te hangarau photovoltaic o te rā, inā koa te utu o ngā kōwae photovoltaic. Nā tēnei kua whakaitihia te utu haumi o ngā pūnaha hiko o te rā, ā, kua piki haere te whakataetae o te hiko o te rā.
He maha ngā whenua me ngā rohe kua whakauru i ngā kaupapa here me ngā whāinga hei whakatairanga i te whanaketanga o te pūngao hiko o te rā. Ko ngā mahi pēnei i ngā paerewa pūngao hou, ngā kaupapa tautoko, me ngā whakatenatena taake kei te akiaki i te tipu o te mākete pūngao o te rā.
Ko Haina te mākete PV rā nui rawa atu o te ao, ā, ko rātou te mākete PV nui rawa atu o te ao. Ko ētahi atu o ngā kaiārahi mākete ko te US, Īnia, me ngā whenua o Ūropi.
E matapaetia ana ka tipu tonu te mākete hiko pūngao rā ā muri ake nei. Mā te whakahekenga utu, te whanaketanga hangarau me te tautoko kaupapa here kua whakapakaritia, ka nui haere te hiranga o te hiko pūngao rā i roto i te tuku pūngao o te ao.
Mā te whakakotahitanga o te pūngao hiko o te rā (solar PV) me ngā hangarau rokiroki pūngao, ngā whatunga atamai me ētahi atu momo pūngao hou ka whakaratohia he otinga whakauru atu mō te whakatutuki i tētahi heke mai pūngao pumau.
