Selo la dzuwa ndi chipangizo chomwe chimasintha mwachindunji mphamvu ya kuwala kukhala mphamvu yamagetsi kudzera mu photoelectric effect kapena photochemical effect.Ma cell a solar amtundu wopyapyala omwe amagwira ntchito ndi chithunzi chamagetsi ndi omwe amakhala ambiri, komanso momwe amasankhira ma cell adzuwa amavutitsa anthu ena.Lero, ndidzafotokozera mwachidule chidziwitso cha kugula ma cell a dzuwa.Ndikukhulupirira kuti imakuthandizani.
Pakadali pano, ma cell a solar pamsika amagawidwa kukhala amorphous silicon ndi crystalline silicon.Pakati pawo, crystalline silikoni akhoza kugawidwa mu polycrystalline silikoni ndi single crystal silikoni.Kuthekera kwa kutembenuka kwazithunzi zazinthu zitatuzi ndi: silicon ya monocrystalline (mpaka 17%)> silicon ya polycrystalline (12-15%)> silicon ya amorphous (pafupifupi 5%).Komabe, crystalline silikoni (single crystal silikoni ndi polycrystalline silicon) kwenikweni samapanga panopa pansi pa kuwala kofooka, ndipo silicon ya amorphous ndi yabwino mu kuwala kofooka (mphamvu poyamba imakhala yochepa kwambiri pansi pa kuwala kofooka).Chifukwa chake, pazonse, silicon ya monocrystalline kapena polycrystalline silicon solar cell cell iyenera kugwiritsidwa ntchito.
Tikagula ma cell a dzuwa, cholinga cha chidwi ndi mphamvu ya cell solar.Nthawi zambiri, mphamvu ya solar panel imayenderana ndi dera la chowotcha cha solar.Malo a solar cell wafer sali wofanana ndendende ndi dera la solar encapsulation panel, chifukwa ngakhale ma solar panels ena ndi akulu, chowotcha chimodzi cha solar chimakonzedwa ndi kusiyana kwakukulu, kotero mphamvu ya solar solar sikutanthauza. apamwamba.
Nthawi zambiri, mphamvu ya solar panel imapangitsa kuti mphamvu ya dzuwa ikhale yokwera kwambiri, kotero kuti zomwe zimapangidwira padzuwa zimakhala zazikulu, ndipo batri yake yomangidwayo ikhoza kulipiritsidwa mwamsanga.Koma zoona zake n’zakuti, pakufunika kuti pakhale mgwirizano pakati pa mphamvu ya solar panel ndi kunyamula chaja cha solar.Nthawi zambiri amakhulupirira kuti mphamvu yocheperako ya charger ya solar singakhale yotsika kuposa 0.75w, ndipo solar yamagetsi yachiwiri imatha kupanga 140mA yapano pansi pa kuwala kolimba kokhazikika.Kuwala komwe kumapangidwa ndi dzuwa ndi pafupifupi 100mA.Ngati ndalama zolipiritsa ndizochepa kwambiri pansi pa mphamvu yachiwiri, sipadzakhala zotsatira zoonekeratu.
Pogwiritsa ntchito kwambiri zinthu zosiyanasiyana za dzuwa, maselo a dzuwa amagwiritsidwa ntchito kwambiri m'miyoyo yathu.Koma pamaso pa mitundu yonse ya maselo a dzuwa pamsika, kodi tiyenera kusankha bwanji?
1. Kusankha mphamvu ya batire ya solar cell
Popeza mphamvu zolowetsa za solar photovoltaic power generation system ndizosakhazikika kwambiri, nthawi zambiri zimakhala zofunikira kukonza makina a batri kuti agwire ntchito, ndipo nyali za dzuwa ndizosiyana, ndipo batire iyenera kukonzedwa kuti igwire ntchito.Nthawi zambiri, pali mabatire a lead-acid, mabatire a Ni-Cd, ndi mabatire a Ni-H.Kusankhidwa kwawo kwa mphamvu kumakhudza mwachindunji kudalirika kwa dongosolo ndi mtengo wa dongosolo.Kusankhidwa kwa mphamvu ya batri nthawi zambiri kumatsatira mfundo zotsatirazi: choyamba, poganiza kuti imatha kukumana ndi kuunikira kwausiku, mphamvu zamagulu amtundu wa dzuwa masana ziyenera kusungidwa momwe zingathere, ndipo nthawi yomweyo, ziyenera kusungidwa. athe kusunga mphamvu zamagetsi zomwe zimakwaniritsa zosowa zowunikira nthawi zonse zamtambo ndi mvula.Mphamvu ya batire ndiyochepa kwambiri kuti ikwaniritse zosowa za kuyatsa kwausiku, ndipo mphamvu ya batire ndi yayikulu kwambiri.
2. Kusankhidwa kwa mawonekedwe opangira ma cell a solar
Pakali pano, pali mitundu iwiri ikuluikulu yonyamula ma cell a dzuwa, lamination ndi guluu.Njira yopangira lamination imatha kutsimikizira moyo wogwira ntchito wa ma cell a solar kwa zaka zopitilira 25.Ngakhale kuti guluu-bonding anali wokongola panthawiyo, moyo wogwira ntchito wa maselo a dzuwa ndi zaka 1 ~ 2 zokha.Chifukwa chake, kuwala kwa dzuwa kocheperako komwe kumakhala pansi pa 1W kumatha kugwiritsa ntchito mawonekedwe amtundu wa glue-drop ngati palibe moyo wautali.Kwa nyali ya dzuwa yokhala ndi moyo wokhazikika wautumiki, tikulimbikitsidwa kugwiritsa ntchito mawonekedwe opangira ma laminated.Kuphatikiza apo, pali gel osakaniza silikoni ntchito encapsulate maselo dzuwa ndi guluu, ndipo akuti moyo ntchito akhoza kufika zaka 10.
3. Kusankhidwa kwa mphamvu ya dzuwa
Mphamvu yotulutsa ma cell a solar Wp yomwe timayitcha kuti ndi mphamvu yotulutsa mphamvu ya cell ya solar pansi pamikhalidwe yofanana ya dzuwa, yomwe ndi: 101 muyezo wofotokozedwa ndi European Commission, mphamvu ya radiation ndi 1000W/m2, mpweya wabwino ndi AM1.5, ndi kutentha kwa batri ndi 25°C.Zimenezi n’zofanana ndi zimene zimachitika padzuwa masana masana padzuwa.(M'munsi mwa mtsinje wa Yangtze, ukhoza kukhala pafupi ndi mtengo umenewu.) Izi siziri monga momwe anthu ena amaganizira.Malingana ngati pali kuwala kwa dzuwa, padzakhala oveteredwa mphamvu linanena bungwe.Itha kugwiritsidwanso ntchito nthawi zonse pansi pa nyali za fulorosenti usiku.Ndiko kunena kuti, mphamvu yotulutsa mphamvu ya cell solar ndi mwachisawawa.Pa nthawi zosiyanasiyana ndi malo osiyanasiyana, mphamvu yotulutsa ya selo lomwelo la dzuwa ndilosiyana.Deta ya kuwala kwa dzuwa, pakati pa aesthetics ndi kupulumutsa mphamvu, ambiri a iwo amasankha kupulumutsa mphamvu.
