Momwe mungakhazikitsire mphamvu ya dzuwa

Ndizosavuta kukhazikitsa dongosolo lomwe lingathe kupanga magetsi. Pali zinthu zisanu zofunika:

1. Zipangizo zamagetsi

2. Chigawo bulaketi

3. Zingwe

4. Inverter yolumikizidwa ndi gridi ya PV

5. Mamita oikidwa ndi kampani ya grid

Kusankhidwa kwa solar panel (module)

Pakadali pano, ma cell a solar pamsika amagawidwa kukhala amorphous silicon ndi crystalline silicon. Crystalline silikoni akhoza kugawidwa mu polycrystalline pakachitsulo ndi monocrystalline pakachitsulo. Photoelectric kutembenuka mphamvu ya zipangizo zitatu ndi: monocrystalline silikoni> polycrystalline silikoni> amorphous silikoni. Silicon ya crystalline (silicon ya monocrystalline ndi silicon ya polycrystalline) kwenikweni sipanga magetsi pansi pa kuwala kofooka, ndipo silicon ya amorphous imakhala ndi kuwala kofooka bwino (pali mphamvu zochepa pansi pa kuwala kofooka). Chifukwa chake, nthawi zambiri, silicon ya monocrystalline kapena polycrystalline silicon solar cell cell iyenera kugwiritsidwa ntchito.

2. Kusankha kuthandizira

Solar photovoltaic bracket ndi bracket yapadera yopangidwira kuyika, kukhazikitsa ndi kukonza ma solar solar mu solar photovoltaic power generation system. Zida zonse ndi aluminiyumu aloyi ndi zitsulo zosapanga dzimbiri, zomwe zimakhala ndi moyo wautali wautumiki pambuyo pa galvanizing yotentha. Thandizo limagawidwa makamaka m'magulu awiri: kutsata kosakhazikika komanso kodziwikiratu. Pakalipano, zothandizira zina zokhazikika pamsika zimathanso kusinthidwa malinga ndi kusintha kwa nyengo kwa kuwala kwa dzuwa. Mofanana ndi pamene idakhazikitsidwa koyamba, malo otsetsereka a gulu lililonse la dzuwa akhoza kusinthidwa kuti agwirizane ndi ma angles osiyanasiyana a kuwala mwa kusuntha zomangira, ndipo solar panel ikhoza kukhazikitsidwa molondola pa malo omwe atchulidwapo polimbitsanso.

3. Kusankha chingwe

Monga tafotokozera pamwambapa, inverter imatembenuza DC yopangidwa ndi solar solar kukhala AC, kotero gawo lochokera pa solar solar kupita kumapeto kwa DC inverter limatchedwa mbali ya DC (DC mbali), ndipo mbali ya DC imayenera kugwiritsa ntchito yapadera. photovoltaic DC chingwe (DC chingwe). Kuphatikiza apo, pakugwiritsa ntchito ma photovoltaic, magetsi a dzuwa amagwiritsidwa ntchito m'malo ovuta kwambiri, monga UV amphamvu, ozoni, kusintha kwakukulu kwa kutentha ndi kukokoloka kwa mankhwala, zomwe zimati zingwe za photovoltaic ziyenera kukhala ndi kukana kwanyengo, UV ndi ozoni kukana dzimbiri, ndi kutha kupirira kusintha kosiyanasiyana kwa kutentha.

4. Kusankhidwa kwa inverter

Choyamba, ganizirani momwe ma solar panel amayendera. Ngati ma solar akonzedwa mbali ziwiri nthawi imodzi, tikulimbikitsidwa kugwiritsa ntchito inverter yapawiri MPPT (pawiri MPPT). Pakadali pano, zitha kumveka ngati purosesa yapawiri, ndipo pachimake chilichonse chimawerengera mbali imodzi. Kenako sankhani inverter ndi ndondomeko yomweyo malinga ndi mphamvu anaika.

5. Mamita oyeza (mamita anjira ziwiri) okhazikitsidwa ndi kampani ya grid

Chifukwa chokhazikitsa mita yamagetsi yamagetsi awiri ndikuti magetsi opangidwa ndi photovoltaic sangathe kudyedwa ndi ogwiritsa ntchito, pamene magetsi otsala ayenera kutumizidwa ku gridi, ndipo mita yamagetsi imayenera kuyeza nambala. Pamene magetsi a photovoltaic sangathe kukwaniritsa zofunikira, amafunika kugwiritsa ntchito magetsi a gridi, omwe amafunika kuyeza nambala ina. Watt single watt hour metre sangathe kukwaniritsa izi, kotero ma watt hour anzeru mamita okhala ndi bidirectional watt hour kuyeza mita amagwiritsidwa ntchito.
