I-Power Generation empeleni ingaphansi kwe-15%, Uma uhlelo lwamandla elanga lufakwe ngale ndlela.

Fi-oreword

Uma indlu inophahla lukakhonkolo, ibheke empumalanga kuya entshonalanga noma entshonalanga kuya empumalanga.Ingabe amaphaneli elanga ahlelwe abheke eningizimu, noma ngokuya ngendlu?

Ukuhlelwa ngokusho kokuma kwendlu kuhle kakhulu, kodwa kukhona umehluko othile ekukhiqizeni amandla kusukela ekuhleleni okubheke eningizimu.Ungakanani umehluko othize wokuphehla amandla?Sihlaziya futhi siphendule lo mbuzo.

01

Uhlolojikelele lwephrojekthi

Uma sithatha iDolobha laseJinan, esifundazweni saseShandong njengereferensi, inani lemisebe yonyaka lingu-1338.5kWh/m²

Thatha uphahla lukasimende wasendlini njengesibonelo, uphahla luhlala entshonalanga kuya empumalanga, isamba samamojula angu-48pcs we-450Wp photovoltaic modules angafakwa, nenani eliphelele lama-21.6kWp, kusetshenziswa i-GoodWe GW20KT-DT inverter, amamojula we-pv afakwe eningizimu. , futhi i-engeli yokuthamba ingu-30°, njengoba kuboniswe esithombeni esingezansi.Umehluko ekuphehleni kukagesi ku-30°/45°/60°/90° eningizimu ngempumalanga kanye no-30°/45°/60°/90° eningizimu ngentshonalanga ulingisiwe ngokulandelana.

02

I-Azimuth kanye ne-Irradiance

I-engeli ye-azimuth isho i-engeli ephakathi kokuma kwe-array photovoltaic kanye nesiqondiso esifanele eningizimu (kungakhathalekile ukuthi ukwehla kazibuthe).Ama-engeli e-azimuth ahlukene ahambisana namanani ahlukene emisebe etholiwe.Ngokuvamile, amalungu afanayo ephaneli yelanga aqondiswe ngasemugqeni onesikhathi eside kakhulu sokuchayeka.i-angle njenge-azimuth engcono kakhulu.

Nge-engeli yokuthambekela egxilile kanye nama-engeli e-azimuth ahlukene, imisebe yelanga eqongelelekayo yonyaka esiteshini samandla.

Cukufakwa:

• Ngokukhula kwe-azimuth angle, i-irradiance iyancipha ngokulinganayo, futhi i-irradiance eningizimu efanele iyona enkulu kunazo zonke.

• Esimeni se-engeli ye-azimuth efanayo phakathi kweningizimu-ntshonalanga naseningizimu-mpumalanga, kunomehluko omncane kunani le-irradiance.

I-Azimuth kanye ne-inter-array shadows

(1) Ngenxa yedizayini yesikhala eseningizimu

Umgomo ojwayelekile wokunquma isikhala se-array ukuthi i-photovoltaic array akufanele ivinjwe phakathi nenkathi yesikhathi kusukela ngo-9:00 am kuya ku-15:00 pm ku-solstice yasebusika.Kubalwa ngokuvumelana nefomula elandelayo, ibanga elime mpo phakathi kwebanga eliphakathi kwamalungu afanayo e-photovoltaic noma isiphephelo esingaba khona kanye nonqenqema olungezansi lwamalungu afanayo akufanele lube ngaphansi kuka-D.

Kubalwe u-D≥5 m

(2) Ukulahleka komthunzi we-array kuma-azimuth ahlukene (ukuthatha eningizimu ngempumalanga njengesibonelo)

Ku-30° empumalanga ukuya eningizimu, kubalwa ukuthi ukulahlekelwa kwethunzi kokuvala imigqa yangaphambili nengemuva yesistimu enkathini yelanga yasebusika ngu-1.8%.

Ku-45° empumalanga ukuya eningizimu, kubalwa ukuthi ukulahlekelwa kwethunzi kokuvaleka kwemigqa yangaphambili nangemuva yesistimu enkathini yelanga yasebusika ngu-2.4%.

Ku-60° empumalanga ukuya eningizimu, kubalwa ukuthi ukulahlekelwa kwethunzi kokuvala imigqa yangaphambili nangemuva yesistimu enkathini yelanga yasebusika ngu-2.5%.

Ku-90° empumalanga ukuya eningizimu, kubalwa ukuthi ukulahleka kokuvaleka kwethunzi kwemigqa yangaphambili nengemuva yesistimu enkathini yelanga yasebusika ngu-1.2%.

Ngesikhathi esifanayo ukulingisa ama-engeli amane ukusuka eningizimu kuya entshonalanga kuthola igrafu elandelayo:

Isiphetho:

Ukulahlekelwa kwe-shading yamalungu afanayo angaphambili nangemuva akubonisi ubuhlobo bomugqa ne-azimuth angle.Lapho i-azimuth angle ifinyelela i-angle engu-60 °, ukulahlekelwa kwe-shading yamalungu angaphambili nangemuva kuncipha.

Ukuqhathanisa kokulingisa kokukhiqiza amandla

Kubalwe ngokomthamo ofakiwe ongu-21.6kW, kusetshenziswa izingcezu ezingu-48 zamamojula angu-450W, intambo engu-16pcsx3, kusetshenziswa inverter engu-20kW

Ukulingisa kubalwa kusetshenziswa i-PVsyst, okuguquguqukayo kuyi-engeli ye-azimuth kuphela, okunye kuhlala kungashintshiwe:

Isiphetho:

• Njengoba i-angle ye-azimuth ikhula, ukukhiqizwa kwamandla kuncipha, futhi ukukhiqizwa kwamandla ngamadigri angu-0 (okufanele eningizimu) kukhulu kakhulu.
• Endabeni ye-engeli ye-azimuth efanayo phakathi kweningizimu-ntshonalanga naseningizimu-mpumalanga, kukhona umehluko omncane enanini lokukhiqiza amandla.
• Ihambisana nethrendi yenani le-irradiance

05

Isiphetho

Eqinisweni, ucabanga ukuthi i-azimuth yendlu ayihlangabezani ne-orientation yaseningizimu, indlela yokulinganisa ukukhiqizwa kwamandla kanye nobuhle bokuhlanganiswa kwesiteshi samandla kanye nendlu idinga ukuklanywa ngokuvumelana nezidingo zayo.
