Moqapi oa potoloho oa li-module tsa photovoltaic tsa letsatsi

Li-module tsa photovoltaic tsa letsatsi, e tsejoang hape e le lisebelisoa tsa letsatsi, ke karolo ea bohlokoa ea lisebelisoa tsa matla a letsatsi. Li-module li etselitsoe ho fetolela khanya ea letsatsi hore e be motlakase, e leng se etsang hore e be karolo ea bohlokoa lefapheng la matla a tsosolositsoeng. Moralo oa potoloho oa li-module tsa photovoltaic tsa letsatsi ke tsa bohlokoa ho netefatsa ts'ebetso e ntle le e bolokehileng ea litsamaiso tsena. Sengoliloeng sena, re tla shebana le ho rarahana ha moralo oa potoloho ea potoloho ea solar PV, re lekola likarolo tsa bohlokoa le lintlha tse amehang.

Mokotla oa motlakase oa letsatsi oa PV ke sele ea photovoltaic (PV), e ikarabellang bakeng sa ho fetola khanya ea letsatsi motlakase. Lisele tsena hangata li entsoe ka lisebelisoa tsa semiconductor tse kang silicon, 'me ha li pepesehile letsatsing, li hlahisa motlakase o tobileng (DC). Ho sebelisa matla ana a motlakase, moralo oa potoloho oa mojule oa photovoltaic oa letsatsi o kenyelletsa likarolo tse 'maloa tsa bohlokoa.

E 'ngoe ea likarolo tse ka sehloohong tsa moralo oa potoloho ea mochine oa motlakase oa photovoltaic ke bypass diode. Li-bypass diode li kenyelelitsoe mojuleng ho fokotsa litlamorao tsa moriti kapa ho hloleha hoa lisele. Ha sele ea letsatsi e le moriti kapa e senyehile, e fetoha tšitiso ho phallo ea motlakase, e fokotsa tlhahiso ea kakaretso ea module. Li-bypass diode li fana ka tsela e 'ngoe ea hore hona joale e fete lisele tse nang le moriti kapa tse hlōlehileng, ho netefatsa hore ts'ebetso ea kakaretso ea module ha e amehe haholo.

Ntle le li-diode tsa bypass, moralo oa potoloho oa li-module tsa photovoltaic tsa letsatsi le tsona li kenyelletsa mabokose a mateano. Lebokose la marang-rang le sebetsa e le sehokelo lipakeng tsa li-module tsa PV le sistimi ea motlakase ea kantle. E boloka likhokahano tsa motlakase, li-diode le likarolo tse ling tse hlokahalang hore mojule o sebetse ka mokhoa o sireletsehileng le ka nepo. Lebokose la mateano le boetse le fana ka tšireletso khahlanong le maemo a tikoloho a kang mongobo le lerōle, ho sireletsa likarolo tsa ka hare tsa module.

Ho feta moo, moralo oa potoloho oa li-module tsa PV tsa letsatsi o kenyelletsa balaoli ba litefiso, haholo-holo litsamaisong tse kantle ho grid kapa li-stand-alone. Lilaoli tsa ho tjhaja li laola phallo ea motlakase ho tloha liphanele tsa letsatsi ho ea ho pakete ea betri, ho thibela ho tjhaja ho feta tekano le ho tsoa ho tebileng ha betri. Sena se bohlokoa bakeng sa ho lelefatsa bophelo ba betri le ho netefatsa botsitso bo akaretsang ba lipolanete tsa letsatsi.

Ha ho etsoa li-circuits tsa motlakase oa letsatsi la photovoltaic, litekanyetso tsa motlakase le tsa morao-rao tsa tsamaiso eohle li tlameha ho nkoa. Ho hlophisoa ha li-modules, ebang ke letoto, li-parallel kapa motsoako oa bobeli, li ama matla le maemo a hona joale ka har'a potoloho. Sekhahla se nepahetseng sa potoloho le tlhophiso ke tsa bohlokoa ho eketsa tlhahiso ea matla ea li-module tsa photovoltaic tsa letsatsi ha li ntse li boloka polokeho le botšepehi ba sistimi.

Ho phaella moo, moralo oa potoloho oa li-module tsa photovoltaic tsa letsatsi li tlameha ho lumellana le litekanyetso le melaoana e nepahetseng ea tšireletso. Sena se kenyelletsa ts'ireletso e nepahetseng le ts'ireletso ea overcurrent ho thibela likotsi tsa motlakase. Ho lumellana le litekanyetso tsena ho tiisa ho kenngoa le ts'ebetso e sireletsehileng ea lisebelisoa tsa letsatsi, ho sireletsa lisebelisoa le ba amehang.

Lilemong tsa morao tjena, tsoelo-pele ea theknoloji e lumelletse lisebelisoa tsa motlakase le li-microinverter ho kopanngoa le moralo oa potoloho oa li-module tsa letsatsi tsa PV. Lisebelisoa tsena li ntlafatsa ts'ebetso ea mojule ka ho ntlafatsa matla a tsoang ho phanele e 'ngoe le e' ngoe ea letsatsi le ho fetolela motlakase o tobileng ho alternating current (AC) bakeng sa tšebeliso ea lits'ebetso tsa bolulo kapa tsa khoebo. Ka ho kopanya lisebelisoa tsena tsa elektronike tse tsoetseng pele, katleho ka kakaretso le ho tšepahala ha lisebelisoa tsa letsatsi li ntlafatsoa haholo.

Qetellong, moralo oa potoloho oa li-module tsa PV tsa letsatsi o phetha karolo ea bohlokoa ts'ebetsong le ts'ebetsong ea tsamaiso ea letsatsi. Ka ho kopanya likarolo tse kang li-bypass diode, mabokose a marang-rang, balaoli ba litefiso le lisebelisoa tsa elektronike tse tsoetseng pele, moralo oa potoloho o tiisa ts'ebetso e sebetsang hantle le e sireletsehileng ea li-module tsa photovoltaic tsa letsatsi. Ha tlhokahalo ea matla a tsosolositsoeng e ntse e hōla, bohlokoa ba lipotoloho tse matla le tse entsoeng hantle ka li-module tsa photovoltaic tsa letsatsi li ntse li bonahala ka ho eketsehileng, ho bula tsela bakeng sa bokamoso bo tsitsitseng ba matla.

Haeba u thahasella li-module tsa photovoltaic tsa letsatsi, ka kopo ikutloe u lokolohile ho ikopanya le Radiancebakeng sa qotso.
