O a mea o lo'o iai ile Rooftop Solar Photovoltaic Systems?
Faʻavae i luga o sini o le carbon neutrality a le lalolagi, fa'aogaina o le la (PV) i luga o le fale faʻapipiʻi faʻaauau pea ona faʻateleina. O faʻapipiʻi faʻasalalauga faʻasalalau i le lalolagi na tu i le 120 GW i le 2023, lea e sili atu i le 58% na faʻapipiʻiina i luga o fale e nonofo ai, e tusa ai ma faʻamaumauga mai le International Renewable Energy Agency (IRENA). O nei faiga tu'ufa'atasia o le gaosiga o le eletise, teuina, ma le fa'aaogaina o lo'o fa'afouina le vaega o le malosi e ala i a latou fa'avae faufale ma tekonolosi. O lea la, o le a le mea moni o le rooftop solar PV system? Se'i o tatou su'esu'e auiliili.
