Photovoltaics Common claculation formulas
Conversion efficiency
η= Pm (lub zog siab tshaj plaws ntawm lub xov tooj ntawm tes) / A (chaw ntawm lub xov tooj ntawm tes) × Pin (qhov xwm txheej lub teeb hluav taws xob hauv ib cheeb tsam)
Ntawm lawv: Pin =1KW/㎡=100mW/cm²
Cov khoom siv roj teeb tau txuas nrog hauv cov koob thiab sib luag
1 Tus naj npawb ntawm cov roj teeb modules txuas nrog nyob rau hauv parallel=Nruab nrab txhua hnub lub zog noj ntawm lub load (Ah) / Nruab nrab txhua hnub lub zog tsim ntawm module (Ah)
2 Tus naj npawb ntawm cov roj teeb modules hauv series=qhov system khiav hauj lwm voltage (V) × coefficient 1.43/module peak operating voltage (V)
Roj teeb muaj peev xwm
Roj teeb muaj peev xwm=Nruab nrab lub zog noj ib hnub load (Ah) × Tus naj npawb ntawm cov hnub los nag sib law liag / Qhov siab tshaj plaws ntawm qhov tso tawm
