Power Power da Matsayi na Gwaji (STC)
A wasanwar Moduleic Module an auna ta a ƙarƙashin yanayin gwaji (STC), wanda aka ayyana da IEL 60904-1 daidaitaccen:
- Irradiance na 1000 w / m² (mafi kyawun hasken rana)
- Zazzabi na Module a 25 ° C
- Daidaitaccen haske na haske (IEL 6094-3)
Bifacail kayayyaki, wanda ya kama haske a garesu, zai iya inganta samarwa ta hanyar ƙasa mai nuna (albedo). PVGIS Shin ba tukuna samfurin waɗannan hanyoyin, amma hanya ɗaya ita ce don amfani da Bnpi (Bifacial sunan irradiance), an ayyana shi: P_Bnpi = P_STC * (1 + φ * 0.135), a ina φ ne bizacality factor.
Iyakantarwa na kayan masarar beli Rashin daidaitawa don shigowar-hadewar shigarwa inda baya ketare module ya hana. Maɗaukaki ya danganta da daidaituwa (misali, axis na arewa maso yamma tare da gabas-West fuskantar).
Kimanta ainihin ikon PV kayayyaki
Halin da yanayin aiki na PV ya bambanta daga daidaitattun yanayin (StC), wanda ke shafar ƙarfin fitarwa. PVGIS.COM ya shafi gyara da yawa don haɗa waɗannan masu canji.
1. Tunani da kusurwa na haske
Lokacin da haske ya same shi wani yanki na PV, wanda aka bayyana yanki ba tare da canzawa zuwa wutar lantarki ba. Morearin m kusurwar waje, mafi girman asarar.
- Tasiri akan samarwa: A matsakaici, wannan tasirin yana haifar da asarar 2 zuwa 4%, ya rage don tsarin siyarwar rana.
2. Tasirin Spectrum Spectrum akan Ingancin PV
Rikicin rana suna kula da wasu igiyar ruwa na bakan haske, wanda ya bambanta ta Fasahar PV:
- Crystalline silicon (C-Si): m don infrared da bayyane haske
- CDte, Cigs, A-SI: Sihiri daban, tare da rage martani a cikin infrared
Abubuwa sun tasiri da bakan: Worning da maraice haske shine sake fitarwa.
Kwanaki na girgije suna ƙara yawan rabo na haske. Sakamakon fitowar kai tsaye yana tasiri kan ikon PV. PVGIS.COM Yana amfani da bayanan tauraron dan adam don daidaita waɗannan bambance-bambancen kuma yana haɗa waɗannan gyare-gali a lissafin sa.
Dogaro da ikon PV akan irradiance da zazzabi
Zazzabi da inganci
Ingancin PV bangarorin PV suna raguwa da zazzabi na module, gwargwadon fasaha:
A babban iradiance (>1000 w / m²), zazzabi na module yana ƙaruwa: asarar inganci
A low irradiance (<400 w / m²), Inganci ya bambanta bisa ga nau'in sel na PV
Yin zane a ciki PVGIS.COM
PVGIS.COM Daidaita ikon PV dangane da irradiance (g) da module zazzabi (tm) ta amfani da samfurin lissafi (Huld et al., 2011):
P = (g / 1000) * a * cim (g, tm)
Matsakaicin musamman ga kowane fasaha na PV (C-Si, CDTE, CDTES) an samo shi ne daga ma'aunin gwaji kuma ana amfani da shi PVGIS.COM kwaikwayo.
Yin zane-gyare da zazzabi na masara
- Abubuwa sun tasiri yawan zafin jiki (tm)
- Yanayi na yanayi zazzabi (Ta)
- Solar irradiance (g)
- Samun iska (W) - iska mai ƙarfi tana sanyaya module

Model model a cikin PVGIS (Faiman, 2008):
Tm = ta + g / (U0 + U1w)
Da coeffice up da U1 sun bambanta bisa ga nau'in shigarwa:

Asarar tsarin da tsufa na PV kayayyaki
Duk lissafin da suka gabata suna ba da iko a matakin module, amma dole ne a dauki asarar asarar:
- Asarar juyawa (Inverter)
- Wayar asara
- Bambance-bambance a cikin iko tsakanin kayayyaki
- Tsufa na pv bangel
Dangane da binciken da Kurtz (2013), bangarorin PV sun yi asara a matsakaita 0.5% na iko a shekara. Bayan shekara 20, an rage ƙarfin su zuwa 90% na ƙimar farko.
- PVGIS.COM Ya bada shawara shigar da asarar tsarin farko na 3% na farkon shekarar zuwa asusu don lalata tsarin, sannan 0.5% a kowace shekara.
Sauran dalilai ba su la'akari a ciki PVGIS
Wasu sakamakon tasiri kan samar da PV amma ba a haɗa su cikin PVGIS:
- Snow a kan bangarorin: Grastically rage samarwa. Ya dogara da mita da tsawon lokacin dusar ƙanƙara.
- Tara ƙura da datti: Rage ikon PV, gwargwadon tsaftacewa da hazo.
- M inuwa: Yana da tasiri mai karfi idan wani module ya girgiza. Dole ne a gudanar da wannan tasirin lokacin shigarwar PV.
