Hanyar lissafin wutar lantarki module PV

Ɗauki ƙarfin fitarwa na 100W kuma yi amfani da shi tsawon sa'o'i 6 a rana a matsayin misali don gabatar da hanyar lissafi:

1. Da farko lissafin watt-hours cinyewa kowace rana (ciki har da asarar inverter): idan juzu'in juzu'i na inverter shine 90%, to lokacin da ƙarfin fitarwa ya kasance 100W, ainihin ƙarfin shigar da ake buƙata ya zama 100W/90% = 111W; idan aka yi amfani da shi na tsawon sa'o'i 5 a rana, yawan wutar lantarki shine 111W*5 hours = 555Wh.

2. Lissafi na PV modules: An ƙididdige shi bisa ga hasken rana mai tasiri na yau da kullum na 6 hours, sa'an nan kuma la'akari da yadda ya dace da caji da asarar yayin aiwatar da caji, ƙarfin fitarwa na PV modules ya kamata ya zama 555Wh / 6h / 80% = 116W. 80% wanda shine ainihin ikon da PV modules ke amfani dashi yayin aikin caji.
