ithathwe ngoba ibhethri ligcwale
Izibalo zanyanga zonke zokuthi ibhethri ligcwala kangaki noma lingabi nalutho phakathi nosuku.
I-Histogram yezibalo zokushajwa kwebhethri
Lokhu kufinyelelwa ngezinkinobho:
Sicela uqaphele lokhu okulandelayo ukuze uhumushe imiphumela engaphandle kwegridi:
i) I-PVGIS 5.3 yenza zonke izibalo zehora
nge
ihora
ngesikhathi esiphelele
uchungechunge lwelanga
idatha yemisebe esetshenzisiwe. Isibonelo, uma usebenzisa I-PVGIS-SARAH2
uzosebenza no-15
iminyaka yedatha. Njengoba kuchaziwe ngenhla, ukuphuma kwe-PV kungu
kulinganiselwa.ihora nehora kusukela ku
uthole i-irradiance esendizeni. La mandla ahamba
ngqo ku
umthwalo futhi uma kukhona
ngokweqile, la mandla engeziwe uya ukushaja
ibhethri.
Uma kwenzeka okukhiphayo kwe-PV kulelo hora kungaphansi kunokusetshenziswa, amandla ashodayo azokwazi
kube
ethathwe ebhethrini.
Ngaso sonke isikhathi (ihora) lapho isimo sokushajwa kwebhethri sifinyelela ku-100%, I-PVGIS 5.3
yengeza usuku olulodwa esibalweni sezinsuku lapho ibhethri ligcwala khona. Lokhu bese kusetshenziselwa
linganisela
% wezinsuku lapho ibhethri ligcwala khona.
ii) Ngaphezu kwamanani amaphakathi wamandla angabanjwanga
ngoba
yebhethri egcwele noma
kwe
isilinganiso samandla alahlekile, kubalulekile ukuhlola amanani wenyanga we-Ed kanye
E_ilahlekile_njenge
bazisa ngendlela isistimu yebhethri ye-PV esebenza ngayo.
Isilinganiso sokukhiqiza amandla ngosuku (Ed): amandla akhiqizwa uhlelo lwe-PV oluya ku
umthwalo, hhayi ngokuqondile. Kungenzeka ukuthi ibigcinwe ebhethrini bese isetshenziswa yi-
umthwalo. Uma uhlelo lwe-PV lulukhulu kakhulu, inani eliphakeme yinani lokusetshenziswa komthwalo.
Amandla amaphakathi angathathwanga ngosuku (E_lost_d): amandla akhiqizwa uhlelo lwe-PV okuyilo
ilahlekile
ngoba umthwalo ungaphansi kokukhiqizwa kwe-PV. La mandla awakwazi ukugcinwa ku-
ibhethri, noma uma igciniwe ayikwazi ukusetshenziswa yimithwalo njengoba isivele imboziwe.
Isamba salokhu okuguquguqukayo okubili siyefana ngisho noma amanye amapharamitha ashintsha. Kuphela
kuncike
kumthamo we-PV ofakiwe. Isibonelo, uma umthwalo ubuzoba ngu-0, isamba se-PV
ukukhiqizwa
izoboniswa njenge "amandla awathathwanga". Noma umthamo webhethri ushintsha,
futhi
ezinye eziguquguqukayo zilungisiwe, isamba salawo mapharamitha amabili asishintshi.
iii) Amanye amapharamitha
Iphesenti lezinsuku ezinebhethri eligcwele: amandla e-PV angasetshenzisiwe umthwalo aya ku-
ibhethri, futhi ingagcwala
Iphesenti lezinsuku ezinebhethri elingenalutho: izinsuku lapho ibhethri ligcina lingenalutho
(okungukuthi
umkhawulo wokukhipha), njengoba uhlelo lwe-PV lukhiqize amandla amancane kunomthwalo
"Amandla amaphakathi awathathwanga ngenxa yebhethri eligcwele" ikhombisa ukuthi mangakanani amandla e-PV
ilahlekile
ngoba umthwalo umboziwe futhi ibhethri ligcwele. Isilinganiso sawo wonke amandla
ilahlekile phezu kwe
uchungechunge lwesikhathi oluphelele (E_lost_d) luhlukaniswa ngenani lezinsuku ibhethri elizitholayo
ngokugcwele
icala.
"Amandla amaphakathi ayashoda" amandla ashodayo, ngomqondo wokuthi umthwalo
angeke
kuhlangatshezwana nayo kusuka ku-PV noma ibhethri. Isilinganiso samandla angekho
(I-Consumption-Ed) yazo zonke izinsuku ochungechungeni lwesikhathi oluhlukaniswa ngenani lezinsuku ibhethri
ithola ingenalutho okungukuthi ifinyelela umkhawulo wokukhipha omisiwe.
iv) Uma usayizi webhethri ukhushulwa kanye nokunye
uhlelo
uhlala
okufanayo, i
isilinganiso
amandla alahlekile azokwehla njengoba ibhethri lingagcina amandla amaningi angasetshenziswa
okwe
i
ilayisha ngokuhamba kwesikhathi. Futhi isilinganiso samandla esishodayo siyehla. Nokho, kuzoba khona a
iphuzu
lapho la manani aqala khona ukuphakama. Njengoba usayizi webhethri ukhula, i-PV iyanda
amandla
kungaba
zigcinwe futhi zisetshenziselwe ukulayishwa kodwa kuzoba nezinsuku ezimbalwa lapho ibhethri lithola khona
ngokugcwele
kukhokhiswe, kukhuphula inani lesilinganiso “isilinganiso samandla asithathwanga”.
Ngokufanayo, lapho
kuyoba, ngokuphelele, amandla amancane angekho, njengoba amaningi angagcinwa, kodwa
Lapho
kuzoba inombolo encane
kwezinsuku lapho ibhethri liba ngenalutho, ngakho-ke amandla aphakathi ayashoda
iyanda.
v) Ukuze wazi ngempela ukuthi angakanani amandla anikezwa yi-
I-PV
isistimu yebhethri ku-
imithwalo, umuntu angasebenzisa amanani ajwayelekile wenyanga we-Ed. Phindaphinda ngayinye ngenombolo ye
izinsuku ku
inyanga kanye nenani leminyaka (khumbula ukucabangela iminyaka ye-leap!). Isamba
imibukiso
Kanjani
amandla amaningi aya emthwalweni (ngokuqondile noma ngokungaqondile ngebhethri). Okufanayo
inqubo
kungaba
zingasetshenziswa ukubala ukuthi mangakanani amandla ashodayo, kukhumbula ukuthi
isilinganiso
amandla hhayi
okuthunjiwe nokulahlekile kubalwa kucatshangelwa inani lezinsuku
ibhethri liyathola
ngokugcwele
ishajiwe noma ayinalutho ngokulandelana, hhayi inani eliphelele lezinsuku.
vi) Ngenkathi ohlelweni oluxhunywe kugridi siphakamisa okuzenzakalelayo
inani
ngokulahleka kwesistimu
ku-14%, asikwenzi’t inikeza lokho okuguquguqukayo njengokufakwayo ukuze abasebenzisi bakulungisele i
izilinganiso
yesistimu ye-off-grid. Kulokhu, sisebenzisa inani isilinganiso sokusebenza salo
i
ephelele
isistimu ye-off-grid engu-0.67. Lokhu kungase kube ukulinganisa okuvamile, kodwa kuhlosiwe
ku
hlanganisa
ukulahlekelwa okuvela ekusebenzeni kwebhethri, i-inverter kanye nokuwohloka kwe-
ezahlukene
izingxenye zesistimu

amatafula
amanani angalandwa ngefomethi ye-CSV, json noma ye-PDF. Umsebenzisi uyakhetha
phakathi kokuthathu
amagrafu ngokuchofoza izinkinobho ezifanele:
9. Ngehora ngemisebe yelanga kanye nedatha ye-PV
Idatha yemisebe yelanga esetshenziswa yi I-PVGIS 5.3 iqukethe inani elilodwa lehora ngalinye
a
isikhathi seminyaka eminingi. Leli thuluzi linikeza umsebenzisi ukufinyelela kokuqukethwe okugcwele kwe-solar
imisebe
database. Ngaphezu kwalokho, umsebenzisi angaphinda acele ukubalwa kokuphuma kwamandla e-PV kokukodwa
ihora
ngesikhathi esikhethiwe.
9.1 Izinketho zokufaka emisebeni yehora ne-PV ithebhu yamandla
Kukhona ukufana okuningana Ekubalweni kokusebenza kwesistimu ye-PV exhunywe kugridi
njenge
kahle
njengamathuluzi wokulandela umkhondo wesistimu ye-PV. In the ithuluzi ngehora kungenzeka
khetha
phakathi
indiza engaguquki kanye nesistimu yendiza yokulandelela eyodwa. Okwendiza engaguquki noma i
ukulandelela kwe-eksisi eyodwa
i
ukuthambeka kufanele kunikezwe umsebenzisi noma i-engeli eyehlelayo elungiselelwe kufanele
kukhethwe.

khetha eyokuqala
nangonyaka odlule ngedatha yehora.
Ngokuzenzakalelayo okukhiphayo kuhlanganisa i-global in-plane irradiance. Nokho, kukhona ezinye ezimbili
izinketho zokukhipha idatha:
Amandla e-PV Ngale nketho, namandla esistimu ye-PV enohlobo olukhethiwe lokulandela umkhondo
izobalwa. Kulokhu, ulwazi mayelana nohlelo lwe-PV kufanele lunikezwe, njengoba nje
okwe
ukubala kwe-PV exhunywe kugridi
Izingxenye zemisebe Uma le nketho ikhethiwe, futhi iqondile, isakazwa futhi iboniswa phansi
izingxenye zemisebe yelanga zizokhishwa.
Lezi zinketho ezimbili zingakhethwa ndawonye noma ngokwehlukana.
9.2 Okukhiphayo kwethebhu yemisebe yehora ne-PV yamandla
Ngokungafani namanye amathuluzi ku I-PVGIS 5.3, ngedatha yehora kunenketho kuphela yokuthi
ukulanda
idatha ngefomethi ye-CSV noma ye-json. Lokhu kungenxa yenani elikhulu ledatha (kufika ku-16
iminyaka ngehora
values), lokho kungenza kube nzima futhi kudle isikhathi ukukhombisa idatha njenge
amagrafu. Ifomethi
yefayela eliphumayo lichazwe lapha.
9.3 Qaphela ku I-PVGIS Izitembu zesikhathi zedatha
Amanani wehora we-irradiance we I-PVGIS-SARAH1 kanye I-PVGIS-SARAH2
amasethi edatha atholiwe
kusukela ekuhlaziyweni kwezithombe ezivela ku-geostationary European
amasathelayithi. Nakuba, lezi
amasathelayithi athatha isithombe esingaphezu kwesisodwa ngehora, sinqume ukwenza kanjalo kuphela
sebenzisa isithombe esisodwa ngehora
futhi unikeze lelo nani elisheshayo. Ngakho-ke, inani le-irradiance
kuhlinzekwe ku I-PVGIS 5.3 yi
i-irradiance esheshayo ngesikhathi esikhonjiswe ku
i
isitembu sesikhathi. Futhi nakuba sikwenza
ukucabanga ukuthi lelo nani le-irradiance esheshayo
ngabe
kube inani eliyisilinganiso salelo hora, ngo
iqiniso liyi-irradiance ngalowo mzuzu.
Isibonelo, uma amanani e-irradiance eku-HH:10, ukulibaziseka kwemizuzu eyi-10 kuphuma
isathelayithi esetshenzisiwe kanye nendawo. Isitembu sesikhathi kudathasethi ye-SARAH yisikhathi lapho
isathelayithi “ubona” indawo ethile, ngakho-ke isitembu sesikhathi sizoshintsha nge
indawo kanye
isathelayithi esetshenzisiwe. Okwamasathelayithi e-Meteosat Prime (ahlanganisa iYurophu ne-Afrika ukuze
40deg East), idatha
zivela kumasathelayithi e-MSG kanye ne "iqiniso" isikhathi siyahlukahluka nxazonke
Imizuzu emi-5 ngemuva kwehora
ENingizimu Afrika ukuya emaminithini angu-12 eNyakatho Yurophu. OkweMeteosat
Amasathelayithi aseMpumalanga, i "iqiniso"
isikhathi sihluka kusukela cishe imizuzu engu-20 ngaphambi kwehora ukuya
ngaphambi nje kwehora lapho usuka
ENingizimu kuya eNyakatho. Ezindaweni zaseMelika, i-NSRDB
database, nayo etholakala ku
amamodeli asekelwe kwisathelayithi, isitembu sesikhathi sihlala sikhona
HH:00.
Ukuze uthole idatha evela kumikhiqizo yokuhlaziya kabusha (ERA5 kanye ne-COSMO), ngenxa yendlela i-irradiance elinganiselwe eyiyo
kubalwa, amanani wehora ayinani elimaphakathi le-irradiance elinganiselwe ngalelo hora.
I-ERA5 ihlinzeka ngamavelu kokuthi HH:30, egxile kakhulu ehoreni, kuyilapho i-COSMO ihlinzeka ngehora.
amanani ekuqaleni kwehora ngalinye. Okuguquguqukayo ngaphandle kwemisebe yelanga, njenge-ambient
izinga lokushisa noma isivinini somoya, nazo zibikwa njengamavelu esilinganiso sehora.
Ukuze uthole idatha yehora usebenzisa oen of the I-PVGIS-SARAH yolwazi, isitembu sesikhathi yisona
kwe
idatha ye-irradiance kanye nokunye okuguquguqukayo, okuvela ekuhlaziyweni kabusha, kungamanani
elihambisana nalelo hora.
10. Idatha Ejwayelekile Yonyaka Wesimo Sezulu (TMY).
Le nketho ivumela umsebenzisi ukuthi alande isethi yedatha equkethe Unyaka Ojwayelekile Wesimo Sezulu
(TMY) yedatha. Isethi yedatha iqukethe idatha yehora yezinto eziguquguqukayo ezilandelayo:
