Kulula kakhulu ukufaka uhlelo olungaphehla ugesi. Kunezinto ezinhlanu ezibalulekile ezidingekayo:
1. Amaphaneli elanga
2. Ubakaki wengxenye
3. Amakhebula
4. I-inverter exhunywe kugridi ye-PV
5. Imitha efakwe yinkampani yegridi
Ukukhethwa kwephaneli yelanga (module)
Njengamanje, amaseli elanga emakethe ahlukaniswe abe i-amorphous silicon ne-crystalline silicon. I-crystalline silicon ingahlukaniswa ibe yi-silicon ye-polycrystalline ne-silicon ye-monocrystalline. Ukusebenza kahle kokuguqulwa kwe-photoelectric kwezinto ezintathu yilezi: i-monocrystalline silicon > i-polycrystalline silicon > i-amorphous silicon. I-crystalline silicon (i-silicon ye-monocrystalline ne-polycrystalline silicon) ngokuyisisekelo ayikhiqizi okwamanje ngaphansi kokukhanya okubuthakathaka, futhi i-silicon e-amorphous inokukhanya okuhle okubuthakathaka (kukhona amandla amancane ngaphansi kokukhanya okubuthakathaka). Ngakho-ke, ngokuvamile, i-silicon ye-monocrystalline noma i-polycrystalline silicon ye-solar cell materials kufanele isetshenziswe.
2. Ukukhetha ukusekela
Ubakaki we-solar photovoltaic ubakaki okhethekile oklanyelwe ukubeka, ukufaka nokulungisa ama-solar panel ohlelweni lokukhiqiza amandla elanga le-photovoltaic. Izinto ezijwayelekile ziyi-aluminium alloy nensimbi engagqwali, enempilo ende yesevisi ngemuva kokushiswa komlilo. Ukusekelwa kuhlukaniswe ikakhulukazi izigaba ezimbili: ukulandelela okungaguquki nokuzenzakalelayo. Njengamanje, ezinye izisekelo ezingaguquki emakethe nazo zingalungiswa ngokuya ngezinguquko zesizini zokukhanya kwelanga. Njengalapho iqala ukufakwa, i-slope yephaneli ngayinye yelanga ingashintshwa ukuze ivumelane nama-engeli ahlukene okukhanya ngokuhambisa izinsimbi, futhi iphaneli yelanga ingalungiswa ngokunembile endaweni ecacisiwe ngokuqinisa kabusha.
3. Ukukhetha ikhebula
Njengoba kushiwo ngenhla, i-inverter iguqula i-DC ekhiqizwa iphaneli yelanga ibe yi-AC, ngakho ingxenye esuka kuphaneli yelanga iye ekugcineni kwe-DC ye-inverter ibizwa ngokuthi i-DC side (i-DC side), futhi uhlangothi lwe-DC ludinga ukusebenzisa okukhethekile. ikhebula le-photovoltaic DC (ikhebula le-DC). Ngaphezu kwalokho, izinhlelo zokusebenza ze-photovoltaic, izinhlelo zamandla elanga zivame ukusetshenziswa ezimweni ezinzima zemvelo, njenge-UV eqinile, i-ozone, izinguquko ezinzima zokushisa kanye nokuguguleka kwamakhemikhali, okusho ukuthi izintambo ze-photovoltaic kufanele zibe nokumelana nesimo sezulu esingcono kakhulu, ukumelana ne-UV ne-ozone corrosion, futhi ukwazi ukumelana noshintsho olubanzi lokushisa.
4. Ukukhethwa kwe-inverter
Okokuqala, cabangela ukuma kwama-solar panel. Uma amaphaneli elanga ehlelwe ngezindlela ezimbili ngesikhathi esisodwa, kunconywa ukuthi usebenzise inverter yokulandelela i-MPPT (i-MPPT emibili). Okwamanje, ingaqondwa njenge-dual core processor, futhi umongo ngamunye uphatha ukubala ohlangothini olulodwa. Bese ukhetha i-inverter enencazelo efanayo ngokusho komthamo ofakiwe.
5. Amamitha okulinganisa (amamitha ezindlela ezimbili) afakwe yinkampani yegridi
Isizathu sokufaka imitha kagesi yezindlela ezimbili ukuthi ugesi owenziwe nge-photovoltaic awukwazi ukusetshenziswa ngabasebenzisi, kuyilapho ugesi osele udinga ukudluliselwa kugridi, futhi imitha kagesi idinga ukukala inombolo. Lapho ukukhiqizwa kwamandla e-photovoltaic kungakwazi ukuhlangabezana nesidingo, kudinga ukusebenzisa ugesi wegridi, okudinga ukukala enye inombolo. Amamitha ehora le-watt ajwayelekile awakwazi ukuhlangabezana nale mfuneko, ngakho-ke kusetshenziswa amamitha wehora le-watt ahlakaniphile anomsebenzi wokulinganisa imitha yehora le-watt kabili.
