The Power Generation kwenikweni ndi 15% yochepa, Ngati mphamvu ya dzuwa imayikidwa motere.

Fmawu

Ngati nyumba ili ndi denga la konkire, imayang'ana kum'maŵa kupita kumadzulo kapena kumadzulo kupita kum'maŵa.Kodi mapanelo adzuwa amakonzedwa moyang'ana kum'mwera, kapena molingana ndi nyumba yake?

Kukonzekera molingana ndi kayendetsedwe ka nyumbayo ndi kokongola kwambiri, koma pali kusiyana kwina mu mphamvu yamagetsi kuchokera ku makonzedwe akuyang'ana kum'mwera.Kodi pali kusiyana kotani pakati pa kupanga magetsi?Timasanthula ndikuyankha funso ili.

Chidule cha Ntchito

Kutengera Jinan City, m'chigawo cha Shandong monga katchulidwe, kuchuluka kwa radiation pachaka ndi 1338.5kWh/m²

Tengani denga la simenti monga chitsanzo, denga limakhala kumadzulo mpaka kum'mawa, ma 48pcs a 450Wp photovoltaic modules akhoza kukhazikitsidwa, ndi mphamvu zonse za 21.6kWp, pogwiritsa ntchito GoodWe GW20KT-DT inverter, ma modules a pv amaikidwa kumwera. , ndipo ngodya yopendekera ndi 30°, monga momwe chithunzi chili m’munsichi chikusonyezera.Kusiyana kwa kupanga mphamvu pa 30°/45°/60°/90° kum’mwera chakum’mawa ndi 30°/45°/60°/90° kum’mwera ndi kumadzulo kumayerekezeredwa motsatana.

Azimuth ndi Irradiance

Azimuth ngodya imatanthawuza mbali yomwe ili pakati pa malo a photovoltaic array ndi chifukwa chakumwera (mosasamala kanthu za kuchepa kwa maginito).Makona osiyanasiyana a azimuth amafanana ndi kuchuluka kwa ma radiation omwe alandilidwa.Nthawi zambiri, gulu la solar panel limayang'ana komwe kuli ndi nthawi yayitali kwambiri yowonekera.ngodya ngati azimuth yabwino kwambiri.

Ndi ngodya yokhazikika yokhazikika komanso ma azimuth osiyanasiyana, ma radiation a dzuwa a pachaka a station yamagetsi.

Ckuphatikiza:

• Ndi kuwonjezeka kwa ngodya ya azimuth, kuwalako kumachepa mofanana, ndipo kuwala kwakum'mwera ndiko kwakukulu kwambiri.

• Pankhani ya ngodya yofanana ya azimuth pakati pa kum'mwera chakumadzulo ndi kum'mwera chakum'mawa, pali kusiyana pang'ono mu mtengo wa irradiance.

Azimuth ndi mithunzi yamitundu yosiyanasiyana

(1) Chifukwa cha mapangidwe otalikirana kumwera

Mfundo yodziwika bwino yodziwira kutalika kwa magawowa ndikuti mawonekedwe a photovoltaic sayenera kutsekedwa panthawi ya 9:00 am mpaka 15:00 pm pa nthawi yachisanu.Kuwerengedwa motsatira ndondomeko yotsatirayi, mtunda woyimirira pakati pa mtunda wapakati pa photovoltaic array kapena pogona zotheka ndi m'mphepete mwa pansi pamaguluwo sayenera kukhala osachepera D.

Kuwerengeredwa D≥5m

(2) Kutayika kwa shading pama azimuth osiyanasiyana (kutengera kumwera chakum'mawa monga chitsanzo)

Pa 30 ° kum'mawa ndi kum'mwera, amawerengedwa kuti kutayika kwa mithunzi kutsogolo ndi kumbuyo kwa dongosolo pa nthawi yachisanu ndi 1.8%.

Pa 45 ° kum'mawa ndi kum'mwera, amawerengedwa kuti kutayika kwa mithunzi kutsogolo ndi kumbuyo kwa dongosolo pa nyengo yachisanu ndi 2.4%.

Pa 60 ° kum'maŵa ndi kum'mwera, amawerengedwa kuti kutayika kwa mithunzi kutsogolo ndi kumbuyo kwa dongosolo pa nyengo yachisanu ndi 2.5%.

Pa 90 ° kummawa ndi kum'mwera, amawerengedwa kuti kutayika kwa mithunzi kutsogolo ndi kumbuyo kwa dongosolo pa nyengo yachisanu ndi 1.2%.

Panthawi imodzimodziyo kuyerekezera ma angles anayi kuchokera kumwera kupita kumadzulo kumapeza graph ili:

Pomaliza:

Kutayika kwa shading kutsogolo ndi kumbuyo sikuwonetsa mgwirizano wozungulira ndi ngodya ya azimuth.Pamene ngodya ya azimuth ifika pa ngodya ya 60 °, kutayika kwa shading kutsogolo ndi kumbuyo kumachepa.

Kuyerekeza kwamagetsi opangira magetsi

Mawerengedwe monga anaika mphamvu ya 21.6kW, ntchito 48 zidutswa 450W zigawo, chingwe 16pcsx3, ntchito 20kW inverter.

Kuyerekezera kumawerengeredwa pogwiritsa ntchito PVsyst, kusinthika kumangokhala ngodya ya azimuth, ena onse amakhala osasinthika:

Pomaliza:

• Pamene mbali ya azimuth ikuwonjezeka, mphamvu yamagetsi imachepa, ndipo mphamvu yamagetsi pa madigiri 0 (chifukwa chakum'mwera) ndi yaikulu kwambiri.
• Pankhani ya ngodya yofanana ya azimuth pakati pa kum'mwera chakumadzulo ndi kum'mwera chakum'mawa, pali kusiyana kochepa pamtengo wamagetsi.
• Mogwirizana ndi chikhalidwe cha mtengo wa irradiance

Mapeto

Zoonadi, poganiza kuti azimuth ya nyumbayo sikugwirizana ndi dera lakumwera, momwe angagwiritsire ntchito mphamvu zamagetsi ndi zokondweretsa za kuphatikiza kwa malo opangira magetsi ndi nyumbayo iyenera kupangidwa malinga ndi zosowa zake.
