- Okpomọkụ modul na 25 Celsius
- Ụdị ọkụ dị iche iche (IEC 60904-3)
Modul bifacial, nke na-ewepụta ìhè n'akụkụ abụọ, nwere ike melite mmepụta site na ntụgharị ala (albedo). PVGIS emebebeghị ụdị modulu ndị a, mana otu ụzọ bụ iji BNPI (Bifacial Nameplate Irradiance), akọwara dị ka: P_BNPI = P_STC * (1 + φ * 0.135), ebe φ bụ ihe na-akpata bifaciality.
Mmachi nke modul bifacial: Ekwesighi maka nrụnye agbakwunyere ụlọ ebe a na-egbochi azụ nke modul ahụ. Arụmọrụ dị iche iche dabere na nghazi (dịka ọmụmaatụ, North-South axis na East-West chere ihu).

Mfu sistemu na ịka nká nke modul PV
Ngụkọta niile gara aga na-enye ike na ọkwa modul, mana a ga-atụle ihe efu ndị ọzọ:
- Mfu mgbanwe (nverter)
- Ọnwụ waya
- Ọdịiche dị na ike n'etiti modul
- Ịka nká nke akụkụ PV
Dị ka ọmụmụ nke Jordan & Kurtz (2013), ogwe PV na-efunahụ nkezi 0.5% nke ike kwa afọ. Mgbe afọ 20 gachara, a na-ebelata ike ha na 90% nke uru mbụ ha.
