Mumakwikwi akasimba e "grid parity" muindasitiri ye photovoltaic, kugadzirisa mutengo we kilowatt-awa yega yega yemagetsi kwakabatana nemakwikwi makuru emabhizinesi. Sechishandiso chakakosha mukugadzirwa kwema solar cell modules, kunyatsojeka kwepuratifomu inofamba yemuchina we photovoltaic string welding inokanganisa zvakananga kunaka kwe welding uye kushanda zvakanaka kwekugadzira. Puratifomu ye granite motion yakatsaurirwa kumichina ye photovoltaic string welding, ine kugadzikana kwayo kwekupedzisira kwe 0.5μm/gore, inopa rutsigiro rwehunyanzvi rwekudzikisa mutengo we kilowatt-awa kubva pazviyero zvakasiyana.
Kugadzikana kwakanyanya kunovimbisa kururama kwekunamira uye kunoderedza marara ezvinhu
Munguva yekushongedza tambo dzemasero e photovoltaic, kutsauka panzvimbo yekushongedza kunogona kukonzera kusabatana zvakanaka kwemasero, zvichikanganisa kushanda zvakanaka kwemagetsi emamodule uye kutogadzira zvigadzirwa zvisina kunaka. Nzvimbo yekufamba yechinyakare inowanzoitika nekuda kwezvinhu zvakaita sekuchinja kwekushisa kwezvakatipoteredza uye kudedera kwemuchina, zvichikonzera kutsauka panzvimbo yekushongedza. Kuwanda kwekuwedzera kwekupisa kwepuratifomu yemitambo yegranite kunongowanikwa chete (4-8) × 10⁻⁶/℃. Pamwe chete nechimiro chayo chemukati chakakora uye chakafanana, kugadzikana kwe 0.5μm/gore kunogona kuwanikwa.
Tichitora mutsetse wekugadzira we 1GW photovoltaic module semuenzaniso, kana puratifomu inofamba yakajairika ikashandiswa, kutsauka kwenzvimbo yekuwelda kunokonzerwa nekushanduka kwehukuru kunodarika 0.1mm, izvo zvinogona kukonzera kuti mwero wekukanganisa kwewelding yema solar cells ukwire kusvika 3%. Pakushandisa mapuratifomu emitambo e granite, mwero wekukanganisa kwewelding unogona kudzorwa mukati me 0.5%. Pakudzikiswa kwe1% yega yega kwemwero wekukanganisa, masero ebhatiri anopfuura miriyoni imwe anogona kuponeswa gore rega rega, zvichideredza zvakananga mutengo wekugadzira wezvikamu uye zvichiisa hwaro hwekuderera kwemutengo pa kilowatt-awa.
Deredza kuwanda kwekugadzirisa michina uye kuvandudza kushanda zvakanaka kwekugadzira
Puratifomu yekufamba isina kugadzikana zvakanaka inokonzera kupera kwezvikamu zvekutumira zvinhu nekukurumidza uye kudzikira kwekurongeka kwenzvimbo nekuda kwekushanduka-shanduka panguva yekushandiswa kwenguva refu, uye nekudaro inoda kugadziriswa kwemidziyo nguva nenguva. Mapuratifomu emitambo egranite, nekugadzikana kwawo kwakanyanya, anogona kuderedza kuitika kwematambudziko akadaro.
Nekuda kwekuchinja kwayo kudiki kwe0.5μm pagore, mwero wekupfekwa kwezvinhu zvakakosha zvakaita semuchina wekutumira uye sensor yekuisa muchina wekuisa tambo wakaderera zvakanyanya. Zvichienderana nedata rekuyera rekambani yekugadzira photovoltaic, mushure mekushandisa granite motion platform, kutenderera kwekugadzirisa muchina wekuisa tambo kwakawedzerwa kubva kamwe chete pamwedzi kusvika kamwe chete pakota, uye nguva yekugadzirisa kamwe chete yapfupikiswawo kubva pamaawa masere kusvika kumaawa matatu. Kuderedzwa kwehuwandu hwekugadzirisa michina kunoreva kushanda kwepamusoro kwekugadzira uye kudzikira kwemari yekushandisa nekugadzirisa michina. Zvichienderana netambo yekugadzira ine simba regore re500MW, inogona kuwedzera nguva yekugadzira inoshanda neinenge maawa mazana maviri pagore, kugadzira akawanda ma photovoltaic modules anodarika mamiriyoni mashanu eyuan, uye kuderedza zvakanyanya mutengo pa kilowatt-awa.
Wedzera hupenyu hwebasa remidziyo uye kuderedza mari yekudyara
Mari yekudyara yemichina yekugadzira magetsi inokwira, uye hupenyu hwemichina hunokanganisa zvakananga kudzoka kwemari inodyarwa mumabhizinesi. Nekuda kwekuchinja kwenguva refu uye kukanganisika kwechimiro, mapuratifomu ekufamba akajairika anowanzo kundikana kusangana nezvinodiwa zvekugadzira zvakanyatsonaka kwemakore anopfuura mashanu. Nekuda kweizvozvo, mabhizinesi anofanirwa kutsiva michina pachine nguva, zvichiwedzera kumanikidzwa kwekudyara zvinhu zvakagadziriswa.
Mapuratifomu emitambo eGranite, ane hunhu hwawo hwakagadzikana hwemuviri uye hwemakemikari, anogona kuchengetedza kunyatsoshanda kwenguva refu uye kuwedzera hupenyu hwese hwebasa remuchina wekubatanidza tambo. Ruzivo kubva kune mumwe mugadziri wemidziyo ye photovoltaic runoratidza kuti muchina wekubatanidza tambo une granite motion platform uchiri kugona kuchengetedza kurongeka kwekuisa welding mukati me ±0.1mm mushure mekushandiswa nguva dzose kwemakore masere, zvichizadzisa zvinodiwa zvekugadzirwa kwezvikamu zvinoshanda zvakanyanya. Kusiyana neizvi, zvishandiso zvinoshandisa mapuratifomu ekufambisa akajairika zvinoda kutsiviwa zvikamu zvavo zvepakati kana kuti muchina wese uvandudzwe mushure memakore mashanu. Kuwedzerwa kwenguva yebasa remuchina kunobvumira mari yekudyara zvinhu zvakagadziriswa yemabhizinesi kuti igoverwe kwenguva yakareba, zvichideredzawo chikamu chekuderera kwemutengo wemuchina pa kilowatt-awa.
Kubatsira kugadzirwa kwezvikamu zvinoshanda zvakanaka uye kuwedzera mari inowanikwa pakugadzira magetsi
Kugadzikana kwe0.5μm pagore kunopa vimbiso yekuti muchina wekubatanidza tambo we photovoltaic uwane welding yakanyatsonaka, zvichigonesa mabhizinesi kugadzira ma module e photovoltaic nekushanda kwakasimba. Mukushandiswa kwezviteshi zvemagetsi zvinoshanda, zvikamu zvinoshanda zvakanyanya zvinogona kuwana kugona kwakawanda kwekugadzira magetsi uye kuderedza mwero wekudzikira kwesimba, nokudaro zvichiwedzera mari inowanikwa nechiteshi chemagetsi.
Semuenzaniso, mamodule egirazi maviri ane mativi maviri ane welding yakanyatsogadzirwa anogona kuwedzera kushanda zvakanaka kwekugadzira magetsi ne3% kusvika 5% zvichienzaniswa nemamodule akajairwa. Tora chiteshi chemagetsi che100MW photovoltaic semuenzaniso. Nekushandisa zvikamu zvinoshanda zvakanyanya, zvinogona kugadzira mamwe makilowatt-hours emamiriyoni matatu kusvika mashanu pagore. Kuwedzera kwemari yekugadzira magetsi kunoreva kudzikiswa kwemutengo pa kilowatt-awa, zvichiwedzera kusimudzira hupfumi nemakwikwi ezviteshi zvemagetsi zve photovoltaic.
Puratifomu yegranite inofamba yakatsaurirwa kumichina yekubatanidza tambo ye photovoltaic, ine kugadzikana kwe 0.5μm/gore sechibatsiro chayo chikuru, inoderedza zvizere mutengo wekugadzira ma photovoltaic modules uye mutengo we kilowatt-awa yezviteshi zvemagetsi kuburikidza nenzira dzakasiyana-siyana dzakadai sekuona kuti kusanganisa tambo kwakarurama, kuderedza kugadziriswa kwemidziyo, kuwedzera hupenyu hwemidziyo, uye kufambisa kugadzirwa kwezvinhu zvinoshanda. Inopa rutsigiro rwakasimba rwehunyanzvi kuindasitiri ye photovoltaic kuti iwane "grid parity" uye budiriro inoenderera mberi.
