Nyengo zinayi zogwirira ntchito ndi kusamalira nzeru

Masika
1. Kodi njira yopangira magetsi idzakhudzidwa ndi zinthu monga masamba a masika, mthunzi wa nyumba, ma PV modules, masamba, kapena ngakhale ndowe za mbalame?
Dongosolo lopangira magetsi lingakhudzidwe kwambiri pamene ma module a photovoltaic aikidwa mumthunzi ndi zinthu monga nyumba, masamba, kapena ngakhale ndowe za mbalame. Kuti tipewe zomwe zimatchedwa hot spot effect, zomwe zimachitika pamene magetsi a selo ali otsika kapena osasunthika, ndikofunikira kuti makhalidwe amagetsi a ma cell a PV omwe amagwiritsidwa ntchito mu module iliyonse akhale ofanana. Ma cell a PV okhala ndi mthunzi amagwira ntchito ngati katundu, kukoka mphamvu kuchokera ku ma cell omwe ali pafupi omwe amawunikira kuwala; njirayi imadziwika kuti hot spot phenomenon, ndipo ingayambitse kuwonongeka kwakukulu kwa PV module ngati siiyang'aniridwa. Kuti tipewe kutentha kwambiri m'ma circuits a nthambi zingapo, ma bypass diode ayenera kuyikidwa pa ma module a PV. Mofananamo, inshuwaransi ya DC iyenera kugwiritsidwa ntchito pa chingwe chilichonse cha PV kuti tipewe kutentha kwambiri m'ma circuits ofanana. Mthunzi pa ma cell a PV ukhoza kuchepetsa kutulutsa kwawo ngakhale palibe kutentha komwe kumachitika.

Chilimwe
1. Pa nthawi ya mvula yamkuntho yachilimwe, kodi makina a PV ogawidwa m'nyumba angatetezedwe bwanji makamaka komanso moyenera ku mphezi?
Kugunda kwa mphezi pa makina a dzuwa kumatha kuwononga zida ndikupangitsa makinawo kusagwira ntchito; motero, ndikofunikira kusamala kuti muteteze malo opangira magetsi a photovoltaic ku kugunda kwa mphezi. Njira zotsatirazi zingatengedwe kuti muteteze makina a PV ku mphezi:
1). gulu la PV lalikulu limakhazikika pansi likamangiriridwa bwino ku bulaketi.
2) bokosi la mita ya PV lili pansi ndipo limatetezedwa ndi mphezi.
3) chosinthira magetsi cha PV chili pansi.
Kuyika makina a photovoltaic (PV) pa nyumba yomwe ilipo nthawi zambiri sikutanthauza kuyika makina ena okhazikika, bola ngati chingwe chokhazikika cha makina a PV chikugwirizana ndi makina okhazikika a nyumbayo. Komabe, kaya chogwirira mphezi (ndodo za mphezi) chiyenera kukhazikitsidwa kapena ayi zimadalira tsatanetsatane wa nkhani iliyonse.
2. Ngati mvula yamkuntho yagwa, kodi ndikofunikira kuzimitsa makina opangira magetsi a PV?
Palibe chifukwa chochotsera makina olumikizira magetsi amagetsi m'nyumba chifukwa ali ndi njira zotetezera magetsi. Ndikofunikira kuti muchotse chosinthira magetsi chomwe chili mu bokosi la mita kenako mudule magetsi opita ku module ya PV pazifukwa zachitetezo. Izi ziteteza kuti module yoteteza magetsi isawonongeke ndi mphezi mwachindunji. Zoopsa zokhudzana ndi kulephera kwa module yoteteza magetsi zitha kuchepetsedwa ngati ogwira ntchito ndi okonza magetsi ayesa mwachangu momwe module imagwirira ntchito.
3. Kodi muyenera kusintha zida zomwe zingawonongeke mwamsanga mvula yamkuntho ikagwa?
Sikoyenera kusinthidwa nthawi yomweyo; ndibwino kudikira mpaka m'mawa kwambiri kapena madzulo kwambiri kuti musinthe. Ogwira ntchito ndi kukonza magetsi ku siteshoni yamagetsi adzatumiza anthu ophunzitsidwa bwino kuti akalowe m'malo mwawo ngati mutawadziwitsa nthawi yake.
4. Kodi tingatani kuti tithe kusamalira kutentha ndi mpweya wochuluka kupita ku ma PV modules nthawi yachilimwe?
Popeza mphamvu yotulutsa ya ma module a photovoltaic imachepa pamene kutentha kukukwera, kuwonjezera mphamvu yopangira magetsi kudzera mu mpweya wabwino ndi kutaya kutentha n'kotheka; njira yotchuka kwambiri ndiyo kugwiritsa ntchito mphepo yachilengedwe ngati chopumulira.

Nthawi yophukira
1. M'miyezi youma ya autumn, ndi chinthu chofunika kwambiri kukumbukira popewa ndikulimbana ndi moto m'nyumba zomwe zili ndi makina ogawa magetsi a photovoltaic?
Kutayika kosayerekezeka kwa miyoyo ndi katundu komwe kungachitike chifukwa cha moto kumapangitsa kuti zinthu zomwe zimayaka ndi kuphulika zisaikidwe pafupi ndi makina opangidwa ndi magetsi opangidwa m'nyumba. Pofuna kuchepetsa mwayi woyaka moto, makina a PV ayenera kukhala ndi mphamvu zodziwonera okha, kuzindikira arc, komanso kuteteza moto, kuwonjezera pa njira zachikhalidwe zotetezera moto. Zofunikira zina zikuphatikizapo switch yolumikizira yamagetsi ya DC yomwe ingagwiritsidwe ntchito mosavuta komanso kusungitsa njira yopewera moto ndi kukonza moto pafupifupi 40m iliyonse.
2. Kodi makina opangira magetsi a photovoltaic apitiliza kugwira ntchito ngati mvula kapena chifunga chikupitirira? Kodi tingayembekezere kuti magetsi azizima kapena mphamvu sizikukwanira?
Ma module a solar photovoltaic (PV) amatha kupanga magetsi ngakhale kuwala kochepa; koma, pamene kuli mitambo kapena mvula nthawi zonse, kuwala kwa dzuwa kumatsika, ndipo magetsi ogwiritsira ntchito a PV system sagwira ntchito bwino kuposa magetsi oyambira a inverter, zomwe zimapangitsa kuti makinawo asagwire ntchito. Ndi makina a PV ogawidwa m'nyumba omwe akuyenda limodzi ndi gridi yogawa, kuzima kwa magetsi ndi kusowa kwa magetsi ndi nkhani yakale. Izi zili choncho chifukwa gridiyo imadzibweretsera magetsi yokha pamene makina a PV apakhomo sangakwanitse kukwaniritsa zosowa za katundu kapena alephera kugwira ntchito chifukwa cha mitambo.

Nyengo yozizira
1. Kodi padzakhala kusowa kwa magetsi m'nyengo yozizira?
Zoonadi, kutentha kumakhudza mphamvu zomwe zimachokera ku makina a photovoltaic; zomwe zimakhudza mwachindunji zimaphatikizapo mphamvu ya kuwala, nthawi ya dzuwa, komanso kutentha kwa gawo la solar cell. Tikuyembekeza kuti mphamvu ya kuwala idzakhala yotsika nthawi yozizira chifukwa cha nthawi yochepa ya dzuwa komanso mphamvu zochepa zomwe zimachokera ku magetsi poyerekeza ndi chilimwe. Komabe, chifukwa cha makina a PV olumikizidwa ndi gridi, katunduyo sangawonetse zizindikiro za kusowa kwa magetsi kapena kuzima kwa magetsi bola ngati gridiyo ili ndi magetsi.
