Iyo Power Generation ndeye 15% zvishoma, Kana iyo solar system system yakaiswa nenzira iyi.

Foreword

Kana imba iine denga rekongiri, yakatarisa kumabvazuva kumadokero kana kumadokero kuenda kumabvazuva. Mapanera ezuva akarongwa akatarisa kumaodzanyemba, kana zvinoenderana neimba?

Kurongeka maererano nekutarisa kweimba yacho zvechokwadi kwakanyanyisa kunaka, asi kune imwe mutsauko mukugadzirwa kwemagetsi kubva kugadziriro yakatarisana nekumaodzanyemba. Wakawanda sei musiyano wekugadzira magetsi? Isu tinoongorora uye tinopindura mubvunzo uyu.

Project Overview

Kutora Jinan Guta, Shandong Province sereferensi, iyo yegore nemwaranzi huwandu ndeye 1338.5kWh/m²

Tora denga resimende reimba semuenzaniso, denga rinogara kumadokero kusvika kumabvazuva, yakazara 48pcs ye450Wp photovoltaic modules inogona kuiswa, ine huwandu hwehuwandu hwe21.6kWp, uchishandisa GoodWe GW20KT-DT inverter, ma pv modules akaiswa kumaodzanyemba. , uye kona yekurerekera i30°, sezvakaratidzwa mumufananidzo uri pasi apa. Musiyano mukugadzirwa kwemagetsi pa 30°/45°/60°/90° kumaodzanyemba nekumabvazuva uye 30°/45°/60°/90° maodzanyemba nemadokero anotevedzwa zvakateerana.

Azimuth uye Irradiance

Iyo azimuth angle inoreva kona iri pakati peiyo yekumisikidzwa kweiyo photovoltaic array uye yakafanira yekumaodzanyemba kutungamira (zvisinei nekuderera kwemagineti). Akasiyana azimuth angles anoenderana nehuwandu hwakasiyana huwandu hwemwaranzi yakagamuchirwa. Kazhinji, solar panel array inotungamirwa yakanangana nekurebesa kuratidzwa nguva. kona seyakanakisa azimuth.

Iine yakatemerwa kona yekona uye akasiyana azimuth angles, gore negore cumulative solar radiation yechiteshi chemagetsi.

Ckusanganisa:

• Nekuwedzera kweazimuth angle, iyo irradiance inoderera mutsara, uye irradiance kumaodzanyemba kwakakodzera ndiyo yakakura.

• Muchiitiko cheiyo azimuth angle pakati pemaodzanyemba-kumadokero uye maodzanyemba-kumabvazuva, pane musiyano mudiki mukukosha kwe irradiance.

Azimuth uye inter-array mimvuri

(1) Nekuda kwemaodzanyemba spacing dhizaini

Nheyo yakajairika yekusarudza kuparadzaniswa kweiyo array ndeyekuti iyo photovoltaic array haifanirwe kuvharika panguva kubva 9:00 am kusvika 15:00 pm panguva yechando solstice. Yakaverengerwa zvinoenderana neinotevera fomula, yakatwasuka chinhambwe pakati pechinhambwe chiri pakati peiyo photovoltaic array kana iyo inogoneka pekugara uye yepasi mupendero weiyo array haifanirwe kunge iri pasi peD.

Yakaverengerwa D≥5 m

(2) Array shading kurasikirwa pane akasiyana azimuth (kutora kumaodzanyemba nekumabvazuva semuenzaniso)

Pa 30 ° kumabvazuva nekumaodzanyemba, inoverengerwa kuti mumvuri wekuvhara kurasikirwa kwepamberi uye kumashure mitsara yehurongwa pane yechando solstice ndeye 1.8%.

Pa 45 ° kumabvazuva nekumaodzanyemba, inoverengerwa kuti mumvuri wekuvhara kurasikirwa kwepamberi uye kumashure mitsara yehurongwa pane yechando solstice ndeye 2.4%.

Pa 60 ° kumabvazuva nekumaodzanyemba, inoverengerwa kuti mumvuri wekuvhara kurasikirwa kwepamberi uye kumashure mitsara yegadziriro pane yechando solstice ndeye 2.5%.

Pa90 ° kumabvazuva nekumaodzanyemba, inofungidzirwa kuti mumvuri wekuvhara kurasikirwa kwepamberi uye kumashure mitsara yegadziriro pane yechando solstice ndeye 1.2%.

Panguva imwe chete kutevedzera makona mana kubva kumaodzanyemba kuenda kumadokero kunowana inotevera girafu:

Mhedziso:

Iyo shading kurasikirwa kwepamberi uye kumashure arrays hakuratidzi hukama hwemutsara neazimuth angle. Kana iyo azimuth angle inosvika pakona ye60 °, kurasikirwa kwemumvuri kwepamberi uye kumashure kwemashure kunoderera.

Simba rekugadzira simulation kuenzanisa

Yakaverengerwa zvinoenderana neyakaiswa simba re21.6kW, uchishandisa 48 zvidimbu zve450W modules, tambo 16pcsx3, uchishandisa 20kW inverter.

Iyo simulation inoverengerwa uchishandisa PVsyst, iyo shanduko ingori azimuth angle, iyo yese inoramba isina kuchinjika:

Mhedziso:

• Sezvo azimuth angle inowedzera, simba rekugadzira rinoderera, uye simba rekugadzira pa 0 madhigirii (nekuda kumaodzanyemba) ndiro guru.
• Muchiitiko cheiyo azimuth angle pakati pemaodzanyemba-kumadokero uye kumaodzanyemba-kumabvazuva, pane musiyano mudiki mukukosha kwekugadzira simba.
• Zvinoenderana nemaitiro eiyo irradiance kukosha

Mhedziso

Muzvokwadi, tichifunga kuti azimuth yeimba haina kusangana nechekumaodzanyemba, nzira yekuenzanisa kugadzirwa kwemagetsi uye aesthetics yekubatanidzwa kwechiteshi chemagetsi uye imba inoda kugadzirwa maererano nezvinodiwa zvayo.
