I-Photovoltaic System Ukulahleka nge PVGIS +
PVGIS I-24 ihlinzeka ngokulinganisa okuqondile kokulahleka kwesistimu ye-Photovoltaic konyaka wokuqala wokusebenza. Ngokwezifundo zamazwe aphesheya, ukulahleka kwesistimu kwanda 0.5% ngonyaka ngenxa yokonakaliswa kwemvelo kwamaphaneli elanga. Le modeli yokulinganisa inembe kakhudlwana futhi ilungele kangcono izimo zokusebenza zangempela zomhlaba, ezivumela ukuqapha ukusebenza kwesikhathi eside ukusebenza.
I-Photovoltaic System Ukulahleka nge PVGIS 5.3
Ngokungqubuzanayo, PVGIS 5.3 Ukulinganisa ukulahleka kohlelo lwe-Photovoltaic ngaphezulu Iminyaka engama-20, usebenzisa inani elizenzakalelayo le 14% ngokulahleka okuphelele. Le ndlela eyenziwe lula ihlinzeka ngesibukezo esijwayelekile sezitayela zokulahleka kwamandla ngaphezulu kwesikhathi eseluliwe kepha ayivumeli ukulungisa unyaka nonyaka.
Izimbangela eziphambili zokulahleka ohlelweni lwe-Photovoltaic
Ukulahleka kwesistimu ye-Photovoltaic kungabonakala kwezici eziningana, kufaka phakathi:
- Ukulahleka kwekhebula: Ukumelana nogesi kumakhebuli kanye nokuxhumeka kubangela ukuhlukaniswa kwamandla.
- Ukulahleka kwe-Inverter: Ukusebenza kahle kokuguqula okuqondile kwamanje (i-DC) ukushintshana kwamanje (ac) kuya ngekhwalithi ye-inverter.
- Ukuqina kumamojula: Uthuli, iqhwa, nezinye izinhlansi zinciphisa inani lokukhanya kwelanga, okunciphisa ukusebenza kahle.
- Ukuwohloka kwemodyuli ngokuhamba kwesikhathi: Amaphaneli elanga azwa ukwehla okuncane kokusebenza kahle unyaka ngamunye, kunomthelela ekukhiqizweni kwamandla isikhathi eside.
Ukwehlukaniswa okuningiliziwe kokulahlekelwa ngaphakathi PVGIS +
1. Ukulahleka kwekhebula
- Ukulinganisa Okuzenzakalelayo: 1%
- Amanani Aguqukayo:
- 0.5% ngezintambo ezisezingeni eliphakeme.
- 1.5% Uma ibanga phakathi kwamaphaneli kanye ne-inverter lidlula amamitha angama-30.
2. Ukulahleka kwe-Inverter
- Ukulinganisa Okuzenzakalelayo: 2%
- Amanani Aguqukayo:
- 1% Nge-inverter esebenza kahle (>98% ukuguqulwa kahle).
- 3-4% nge-inverter enokuguqulwa kahle kwama-96%.
3. I-Photovoltaic Module Loss
- Ukulinganisa Okuzenzakalelayo: 0.5% ngonyaka
- Amanani Aguqukayo:
- 0.2% ngamaphaneli wekhwalithi yeprimiyamu.
- 0.8-1% ngamaphaneli asezingeni eliphakathi.
Ukugcina
Ukulahleka kwesistimu ye-Photovoltaic kuncike ezicini ezahlukahlukene zobuchwepheshe nezemvelo.
Ne- PVGIS 24, ungathola ukulinganiswa okunembile okunembile futhi okuguqukayo, okukuvumela ukuthi wenze kahle ukusebenza kwakho kohlelo lwe-Photovoltaic. Ngokucabanga ngentambo, inverter, kanye nokulahleka kwemodyuli, ungakulangazelela kangcono ukukhiqiza amandla wesikhathi eside futhi uthuthukise ukusebenza kahle kohlelo lonke.
