Nekusvika kwechirimo uye kupora kwenyika zvishoma nezvishoma, mwaka wekugadzira simba rezuva wava pedyo. Muchinyorwa chino, tichakurukura mamwe marongero ekutanga ekushandisa nekuchengetedza masisitimu emagetsi ezuva.
Chitubu
1. Ko hurongwa hwekugadzira magetsi huchakanganiswa nezvinhu zvakaita semashizha emuchirimo, mumvuri wemba, maPV modules, mashizha, kana kutoti madota eshiri here?
Sisitimu yekugadzira magetsi inogona kukanganiswa zvakanyanya kana ma module e photovoltaic akaiswa mumvuri nezvinhu zvakaita sedzimba, mashizha, kana kunyange madota eshiri. Kuti tidzivise chinonzi hot spot effect, chinoitika kana mashandiro emagetsi esero asina kunaka kana kuti akaiswa mumvuri, zvakakosha kuti hunhu hwemagetsi hwema PV cells anoshandiswa mu module yega yega huenderane. Ma PV cells ane mumvuri anoshanda semutoro, achitora simba kubva kuma light-sensitive cells ari pedyo; maitiro aya anozivikanwa sehot spot phenomenon, uye anogona kukonzera kukuvara kukuru kuPV module kana ikasatariswa. Kuti tidzivise kupisa zvakanyanya muma series branch circuits, bypass diodes inofanira kuiswa pama PV modules. Saizvozvowo, inshuwarisi yeDC inofanira kushandiswa kune yega yega PV string kudzivirira kupisa zvakanyanya muma parallel circuits. Shade pama PV cells inogona kuderedza kubuda kwawo kunyangwe pasina hot spot effect inoitika.
Zhizha
1. Munguva yemvura ine dutu muzhizha, masisitimu ePV akapararira mudzimba angadzivirirwa sei zvakananga uye zvinobudirira kubva pakurohwa nemheni?
Kurova kwemheni pamagetsi ezuva kunogona kuparadza michina uye kuita kuti magetsi asashande; saka, zvakakosha kutora matanho ekudzivirira magwenya emagetsi ezuva kubva pakurova kwemheni. Matanho anotevera anogona kutorwa kuchengetedza magetsi ePV kubva kumheni:
1). PV square array inotsikwa kana yanyatsobatanidzwa pabracket.
2). Bhokisi rePV mita rakadzika pasi uye rakachengetedzwa nemheni.
3). PV inverter yakamiswa pasi.
Kuisa system ye photovoltaic (PV) pachivako chiripo kazhinji hazvidi kuti pave nesystem ye grounding yakasiyana, chero bedzi mutsetse we grounding we PV system wakabatana nesystem ye grounding yechivako. Zvisinei, kuti lightning catcher (lightning rods) inofanira kuiswa here kana kuti kwete zvinoenderana ne specific ye case yega yega.
2. Kana dutu remvura richinaya, zvinodikanwa here kudzima sisitimu yekugadzira magetsi yePV?
Hapana chikonzero chekudzima masisitimu emagetsi emagetsi anoparadzirwa mumba nekuti ane michina yekuchengetedza mheni. Zvinokurudzirwa kuti ubvise switch yemagetsi inopwanya magetsi mubhokisi remamita wobva wadzima magetsi ePV module nekuda kwezvikonzero zvekuchengetedza. Izvi zvinodzivirira module yekudzivirira mheni kuti isakuvadzwe nemheni yakananga. Njodzi dzinobatanidzwa nekukundikana kwemodule yekudzivirira mheni dzinogona kuderedzwa kana vashandi vekuchengetedza nekuongorora vakaedza nekukurumidza mashandiro emodule.
3. Unofanira here kutsiva zvishandiso zvinokurumidza kubatwa nechirwere mushure mekunge dutu guru rezhizha rasvika?
Hazvina kukodzera kutsiviwa nekukasika; zvakanaka kumirira kusvika mangwanani-ngwanani kana kuti masikati machena kuti utsiviwe. Vashandi vemagetsi vanozotumira vanhu vakadzidziswa kuti vatore nzvimbo yavo kana ukavazivisa nenguva.
4. Tingaita sei kuti kudziya nemhepo zviwedzere uye kufamba kwemhepo kuPV modules munguva yezhizha?
Sezvo simba remagetsi rinobuda kubva kuma photovoltaic modules richiderera sezvo tembiricha dzichikwira, kuwedzera kushanda kwemagetsi kuburikidza nekufefetera uye kupisa kunokwanisika; nzira inonyanya kufarirwa ndeyekushandisa mhepo yechisikigo semuchina wekufema.
Matsutso
1. Mumwedzi yemwaka wekunaya kwemvura, chii chinonyanya kukosha chekufunga nezvacho pakudzivirira nekurwisa moto mudzimba dzine masisitimu emagetsi anopararira?
Kurasikirwa kusingafungidzike kwehupenyu nezvinhu zvinogona kukonzerwa nemoto kunoita kuti zvive zvakakosha kuti zvinhu zvinobvira uye zvinoputika zvisaunganidzwe pedyo nemagetsi emagetsi akapararira mudzimba. Kuti kuderedze mukana wekubvira, maPV system anofanirwa kunge aine kugona kuzvionera ega, kuziva arc, uye kudzivirira moto, pamwe nemaitiro ekuchengetedza moto akajairika. Zvimwe zvinodiwa zvinosanganisira switch yekubvisa magetsi inobvira nekukurumidza uye kubhuka nzira yekudzivirira moto nekukurumidza mushure memamita makumi mana ega ega.
2. Sisitimu yekugadzira magetsi inobuda nechiedza chezuva icharamba ichishanda here kana mvura ikaramba ichinaya kana mhute? Tinogona kutarisira kuti magetsi adzimwe kana kuti magetsi asina kukwana?
Ma solar photovoltaic (PV) modules anogona kugadzira magetsi kunyangwe muchiedza chisina kujeka; asi, kana kuchinge kwava nemakore kana kuti kuchinaya nguva dzose, kupenya kwezuva kunodonha, uye voltage yekushanda yePV system inoderera pane voltage yekutanga ye inverter, zvichiita kuti system isashande. Ne system yePV yakagoverwa kumba inoshanda pamwe chete ne grid yekugovera, kudzimwa kwemagetsi nekushaikwa kwemagetsi chinhu chekare. Izvi zvinodaro nekuti grid inozozadza magetsi otomatiki kana system yePV yemhuri isingakwanise kuzadzisa zvinodiwa nemutoro kana kuti ikasashanda nekuda kwemamiriro ekunze ane makore.
Chando
1. Munguva yechando, pachava nekushaikwa kwemagetsi here?
Zvechokwadi, tembiricha inokanganisa simba rinobuda mumasystem e photovoltaic; zvinhu zvinopesvedzera zvakananga zvinosanganisira kupenya kwemwaranzi, nguva yezuva, uye tembiricha yekushanda kwe solar cell module. Zvinotarisirwa kuti kupenya kwemwaranzi kuchava kwakaderera munguva yechando nekuda kwenguva pfupi yezuva uye kazhinji kugadzirwa kwemagetsi kwakaderera zvichienzaniswa nezhizha. Kunyange zvakadaro, nekuda kwe grid-connected residential distributed PV system, mutoro hauzoratidzi zviratidzo zvekushaikwa kwemagetsi kana kudzimwa chero bedzi grid iine simba.
2. Kudonha kwechando kunoda kucheneswa kwesimba remagetsi rePV here? Chii chinoitika kuzvikamu zvePV kana chando chechando chanyunguduka uye chaoma zvakare? Kuti ndichenese module, ndingamira pamusoro payo here?
Zvakakosha kuchenesa chikamu chacho mushure mekunaya kwechando chakawanda. Shandisa zvinhu zvakapfava kusundira pasi pechando, uchingwarira kuti usakwenya girazi. Chikamu chacho chinogona kutakura mutoro, saka kuchichenesa pamusoro pacho kunogona kukonzera matombo akavanzika kana kukuvara, izvo zvinogona kupfupisa hupenyu hwacho. Kazhinji, haufanirwe kumirira kusvika chando chanyanya kukora kuti uchichenese, sezvo izvi zvinogona kukonzera kutonhora zvakanyanya.
3. Ko sisitimu yemagetsi inoparadzirwa mumba inogona kutsungirira kukuvara kwechimvuramabwe here?
Zvakabvumidzwa uye zvakaedzwa nemasangano akaita seCGC, CQC, kana TUV, pakati pezvimwe, ndizvo zvinoumba sisitimu yePV inoparadzirwa kumba. Zvakajairika kuisa divi repamberi kune mutoro wepamusoro we5400Pa (mutoro wemhepo, mutoro wechando), divi rekumashure kune mutoro wepamusoro we2400Pa (mutoro wemhepo), uye kuisa chivakwa kune bhatiri remiedzo yakaoma, kusanganisira kukanganiswa kwematombo echimvuramabwe e25 mm nekumhanya kwe23 m/s. Saka, sisitimu yekugadzira simba remagetsi ezuva nezuva inowanzo dzivirirwa kubva kuchimvuramabwe.
