Ke sehla sefe se fanang ka ROI e ntle ka ho fetisisa ea ho hloekisa?

Ho hloekisa nakong ea selemo (March-May) ho hlahisa ROI e phahameng ka ho fetisisa (387%) hobane e etella pele nako ea tlhahiso ea tlhōrō. Mariha ho hloekisa ho bontša ROI e tlaase ka ho fetisisa (201%) empa e ntse e na le phaello libakeng tse ngata tsa leholimo.

Mofuta oa inverter o ama ho hloekisa ROI joang?

Li-inverters tsa likhoele tse nang le lisebelisoa tsa motlakase kapa li-microinverter li thusa ho tsebahatsa liphanele tse sa sebetseng hantle, ho eketsa ho hloekisa ROI ka 18-27% ka mekhoa ea tlhokomelo e lebisitsoeng.

A na nka bala ROI bakeng sa sistimi ea ka e ikhethileng?

Sebelisa foromo ena: ROI = [(Ho fumana kWh × Sekhahla sa motlakase) + Lekeno la kakaretso ea mithara - Litsenyehelo tsa ho hloekisa] / Litšenyehelo tsa ho hloekisa × 100. Tsa rona PVGIS lisebelisoa li bala sena ka bohona u sebelisa data ea hau ea sistimi.
