1.2 Hoʻokomo a puka i loko PVGIS 5.3
ʻO ka PVGIS hōʻike ʻia ka mea hoʻohana ma lalo nei.
ʻO ka hapa nui o nā mea hana ma PVGIS 5.3 e koi i kekahi hoʻokomo mai ka mea hoʻohana - kēia mālama ʻia e like me nā palapala pūnaewele maʻamau, kahi e kaomi ai ka mea hoʻohana i nā koho a i ʻole ke komo ʻana i ka ʻike, e like me ka nui o kahi ʻōnaehana PV.
Ma mua o ka hoʻokomo ʻana i ka ʻikepili no ka helu ʻana, pono ka mea hoʻohana e koho i kahi wahi kikoʻī no
ka mea e helu ai.
Hana ʻia kēia e:
Ma ke kaomi ʻana i ka palapala ʻāina, me ka hoʻohana ʻana i ke koho zoom.
Ma ke komo ʻana i kahi helu wahi ma ka "helu wahi" kahua ma lalo o ka palapala ʻāina.
Ma ke komo ʻana i ka latitu a me ka longitude ma nā kahua ma lalo o ka palapala ʻāina.
Hiki ke hookomo i ka latitu a me ka longitude ma ke ano DD:MM:SSA kahi o DD na degere,
MM ka arc-minute, SS na arc-sekona a me A ka hemisphere (N, S, E, W).
Hiki ke hoʻokomo ʻia ka latitu a me ka longitude ma ke ʻano he helu decimal, no laila he 45°15'N
pono
e hookomo e like me 45.25. Hoʻokomo ʻia nā latitu hema o ka equator ma ke ʻano he waiwai ʻino, ʻo ka ʻākau
maikaʻi.
Nā lonitu ma ke komohana o ka 0° Pono e hāʻawi ʻia ka meridian ma ke ʻano he mau waiwai maikaʻi ʻole, nā waiwai hikina
maikaʻi.
PVGIS 5.3 hiki i ka mea hoʻohana e kiʻi i nā hopena ma nā ʻano like ʻole ala:
E like me ka helu a me nā kiʻi i hōʻike ʻia ma ka polokalamu kele pūnaewele.
Hiki ke mālama ʻia nā kiʻi āpau i faila.
E like me ka ʻike ma ke kikokikona (CSV).
Hōʻike kaʻawale ʻia nā ʻano hoʻopuka ma ka "Mea hana" pauku.
Ma ke ʻano he palapala PDF, loaʻa ma hope o ke kaomi ʻana o ka mea hoʻohana e hōʻike i nā hopena i ka polokalamu kele pūnaewele.
Ke hoʻohana nei i ka non-interactive PVGIS 5.3 nā lawelawe pūnaewele (nā lawelawe API).
Hōʻike hou ʻia kēia mau mea ma ka "Mea hana" pauku.
2. Ke hoʻohana nei i ka ʻike horizon
Ka helu ʻana o ka pāhawewe lā a/a i ʻole ka hana PV ma PVGIS 5.3 hiki ke hoʻohana i ka ʻike e pili ana
ka ʻaoʻao kūloko e koho i nā hopena o nā aka mai nā puʻu kokoke a i ʻole
mauna.
He nui nā koho o ka mea hoʻohana no kēia koho, i hōʻike ʻia ma ka ʻākau o ka
palapala 'āina ma ka
PVGIS 5.3 mea paahana.
He ʻekolu mau koho a ka mea hoʻohana no ka ʻike horizon:
Mai hoʻohana i ka ʻike horizon no ka helu ʻana.
ʻO kēia ke koho i ka wā e hoʻohana ai
wehe i ke koho ʻelua i ka "helu ʻia ʻana" a me ka
"hoʻouka i ka waihona horizon"
nā koho.
E hoʻohana i ka PVGIS 5.3 ʻike horizon i kūkulu ʻia.
No ke koho ʻana i kēia, koho
"Heluhelu ʻia" i ka PVGIS 5.3 mea paahana.
ʻO kēia ka
paʻamau
koho.
Hoʻouka i kāu ʻike ponoʻī e pili ana i ke kiʻekiʻe o ka lewa.
ʻO ka faila horizon e hoʻouka ʻia i kā mākou pūnaewele
he waihona kikokikona maʻalahi, e like me ka hiki iā ʻoe ke hana me ka hoʻohana ʻana i kahi hoʻoponopono kikokikona (e like me Notepad no
Windows), a i ʻole ma ka hoʻokuʻu ʻana aku i ka pāpalapala ma ke ʻano he waiwai i hoʻokaʻawale ʻia nā koma (.csv).
Pono e loaʻa i ka inoa faila nā mea hoʻonui '.txt' a i ʻole '.csv'.
I loko o ka faila pono e loaʻa hoʻokahi helu no kēlā me kēia laina, me kēlā me kēia helu e hōʻike ana i ka
horizon
kiʻekiʻe ma nā degere ma kekahi ʻaoʻao panana a puni ka wahi hoihoi.
Pono e hāʻawi ʻia nā kiʻekiʻe horizon ma ka faila ma ka ʻaoʻao ʻākau e hoʻomaka ana ma
Ke akau;
ʻo ia hoʻi, mai ka ʻĀkau, e hele ana i ka Hikina, i ka Hema, i ke komohana, a i ka hoʻi ʻana i ka ʻĀkau.
Manaʻo ʻia nā koina e hōʻike ana i ka lōʻihi angular like a puni ka lewa.
No ka laʻana, inā loaʻa iā ʻoe nā waiwai 36 i ka faila,PVGIS 5.3 manao ia
ka
pono ka helu mua

10 degere komohana
o ka akau.
Hiki ke loaʻa kahi faila laʻana maanei. Ma keia hihia, he 12 wale no helu ma ka waihona,
pili i ke kiʻekiʻe o ka lewa no kēlā me kēia 30 degere a puni ka lewa.
ʻO ka hapa nui o nā PVGIS 5.3 mea paahana (koe nae ka papa manawa hoolele o ka hora).
hōʻike a
pakuhi o ka
horizon me nā hopena o ka helu ʻana. Hōʻike ʻia ka pakuhi ma ke ʻano he polar

Hōʻike ʻia ke kiʻi paʻi kiʻi o ka wahi like no ka hoʻohālikelike.
3. Ke koho ʻana i ka pāhawewe lā waihona waihona
Loaʻa nā ʻikepili pāhawewe lā (DBs) ma PVGIS 5.3 he:
Hāʻawi nā ʻikepili a pau i nā manaʻo hoʻohālikelike o ka lā.
ʻO ka hapa nui o nā ʻIkepili manaʻo mana o ka lā hoʻohana ʻia e PVGIS 5.3 ua helu ʻia mai nā kiʻi ukali. Aia kekahi helu o nā ʻano hana like ʻole e hana ai i kēia, e pili ana i ka hoʻohana ʻana i nā satelite.
ʻO nā koho i loaʻa ma PVGIS 5.3 ma i kēia manawa:
PVGIS-SARAH2 Ua loaʻa kēia pūʻulu ʻikepili
helu ʻia e CM SAF i
pani ia SARAH-1.
Hoʻopili kēia ʻikepili iā ʻEulopa, ʻApelika, ka hapa nui o Asia, a me nā ʻāpana o ʻAmelika Hema.
PVGIS-NSRDB Ua loaʻa kēia pūʻulu ʻikepili hāʻawi ʻia e ka National Renewable Energy Laboratory (NREL) a he ʻāpana o ka Ka Lā Lahui Hoʻoulaula waihona waihona.
PVGIS-SARA ʻO kēia pūʻulu ʻikepili
helu ʻia
na CM SAF a me ka
PVGIS hui.
Loaʻa i kēia ʻikepili kahi uhi like me PVGIS-SARAH2.
ʻAʻole uhi ʻia kekahi mau wahi e ka ʻikepili satellite, ʻo ia ka hihia no ka latitude kiʻekiʻe
mau wahi. No laila, ua hoʻokomo mākou i kahi ʻikepili hoʻoheheʻe solar hou no ʻEulopa, kahi
aia nā latitu ʻākau:
PVGIS-ERA5 He loiloi hou kēia
huahana
mai ECMWF.
ʻO ka uhi ʻana ma ka honua holoʻokoʻa i ka hoʻonā manawa hola a me kahi hoʻonā spatial o
0.28°lat/lon.
ʻIke hou aku e pili ana ka ʻikepili hoʻoheheʻe lā ma muli o ka hoʻoponopono hou ʻana ʻo ia
loaʻa.
No kēlā me kēia koho helu ʻana ma ka ʻaoʻao pūnaewele, PVGIS 5.3 e hoike mai i ka
mea hoʻohana
me kahi koho o nā waihona e uhi ana i kahi i koho ʻia e ka mea hoʻohana.
Hōʻike ka kiʻi ma lalo nei i nā wahi i uhi ʻia e kēlā me kēia ʻikepili hoʻoheheʻe lā.
ʻO kēia mau ʻikepili nā mea i hoʻohana ʻia e ka paʻamau ke hāʻawi ʻole ʻia ka ʻāpana raddatabase
i na mea paahana pili ole. ʻO ia hoʻi nā ʻikepili i hoʻohana ʻia ma ka hāmeʻa TMY.
4. Ka helu ʻana i ka ʻōnaehana PV pili i ka mākia hoʻokō
Pūnaehana Photovoltaic hoohuli i ka ikehu o ka lā i ka ikehu uila. ʻOiai ua hoʻopuka nā modula PV i ka uila pololei (DC), Hoʻohui pinepine nā modules i kahi Inverter e hoʻohuli i ka uila DC i AC, ka mea a laila hiki ke hoʻohana ʻia ma ka ʻāina a i ʻole e hoʻouna ʻia i ka pā uila. ʻO kēia ʻano Pūnaehana PV kapa ʻia ʻo PV pili i ka grid. ʻO ka ʻO ka helu ʻana o ka hoʻoulu ʻana o ka ikehu ke manaʻo nei e hiki i nā ikehu āpau i hoʻohana ʻole ʻia ma ka ʻāina hoʻouna ʻia i ka pā.
4.1 Nā hoʻokomo no ka helu ʻana o ka ʻōnaehana PV
PVGIS pono i kekahi ʻike mai ka mea hoʻohana e hana i ka helu ʻana i ka ikehu PV hana ʻana. Hōʻike ʻia kēia mau mea hoʻokomo ma lalo nei:
ʻO ka hana o nā modula PV e pili ana i ka mahana a me ka ʻālamalama lā, aka, o ka
ʻokoʻa ka hilinaʻi pololei
ma waena o nā ʻano modula PV like ʻole. I kēia manawa hiki iā mākou
koho i na poho ma muli o
ka hopena wela a me ka irradiance no kēia mau ʻano
modules: crystalline silika
nā pūnaewele; nā modula kiʻiʻoniʻoni lahilahi i hana ʻia mai CIS a i ʻole CIGS a me nā kiʻiʻoniʻoni lahilahi
nā modules i hana ʻia mai Cadmium Telluride
(CdTe).
No nā ʻenehana ʻē aʻe (ʻoi aku ka nui o nā ʻenehana amorphous), ʻaʻole hiki ke hoʻoponopono ʻia kēia hoʻoponopono
helu ʻia ma ʻaneʻi. Inā koho ʻoe i kekahi o nā koho mua ʻekolu ma ʻaneʻi ka helu ʻana o
hoʻokō
e noʻonoʻo i ka hilinaʻi wela o ka hana o ka mea i koho ʻia
ʻenehana. Inā koho ʻoe i kahi koho ʻē aʻe ('ē aʻe / ʻike ʻole ʻia), e manaʻo ka helu ʻana i kahi poho
o
8% o ka mana ma muli o nā hopena wela (kahi waiwai maʻamau i ʻike ʻia he kūpono no
nā ʻano anuanu).
Hoʻopili pū ʻia ka mana PV i ka spectrum o ka radiation solar. PVGIS 5.3 hiki
helu
pehea e pili ai nā ʻokoʻa o ka spectrum o ka lā i ka hana ikehu holoʻokoʻa
mai kahi PV
ʻōnaehana. I kēia manawa hiki ke hana ʻia kēia helu ʻana no ka silikona crystalline a me CdTe
modules.
E hoʻomaopopo ʻaʻole i loaʻa kēia helu ʻana i ka wā e hoʻohana ai i ka radiation solar NSRDB
waihona waihona.
ʻO kēia ka mana i haʻi ʻia e ka mea hana e hiki ke hana i ka array PV ma lalo o ke kūlana
nā kūlana hoʻāʻo (STC), he 1000W mau o ka hoʻomālamalama ʻana o ka lā i kēlā me kēia mika square i ka
plane of the array, ma kahi mahana o 25°C. Pono e hoʻokomo i ka mana kiʻekiʻe
kilowatt-peak (kWp). Inā ʻaʻole ʻoe ʻike i ka mana kiʻekiʻe i haʻi ʻia o kāu mau modules akā
ike
