Kutalitali, nyengo yayitali, chipale chofewa - kodi mapulojekiti onga awa amatha kuyendabe ndi dzuwa?
Inde. Ndipo kutentha kochepa komweko ndi bonasi. Ma module a crystalline silicon adavotera pa 25 ° C; pa kutentha kwa 1 ° C kulikonse, zotulutsa zimakwera pafupifupi 0.3% -0.35%. Chifukwa chomwe nyengo yozizira imakhala yotsika si kutentha - ndi masana afupiafupi komanso chipale chofewa. Zonse zikhoza kuthetsedwa mwa kupanga.
Cold Boost Output: Counterintuitive, koma Mothandizidwa ndi Data
Temperature Coefficient Ndiwofunika Kwambiri
Kutentha kwamphamvu kwa ma crystalline silicon modules ndi koipa - kutsika kwa kutentha, kumapangitsanso kutuluka:
| Ukadaulo wama cell | Mphamvu ya kutentha kokwana | Kuchita kwa kutentha kochepa |
| Ochiritsira monocrystalline PERC | Pafupifupi. -0.30% mpaka -0.35%/°C | ≈ + 10% kutulutsa patsiku -5 ° C momveka |
| N-mtundu TOPCon | Pafupifupi. -0.25% mpaka -0.30%/°C | Amataya 0.05% -0.1% kuchepera pa digiri pansi pamikhalidwe yomweyi |
| HJT | Pafupifupi. -0.24% mpaka -0.26%/°C | Kupindula kwakukulu kwa kutentha kochepa |
Tengani gawo la 400W monga chitsanzo: pa kutentha kwa selo -5 ° C, kutulutsa kwenikweni kuli pafupi ndi 442W, 10.5% pamwamba pake; madzulo masana pa kutentha kwa selo la 45 ° C, kutulutsa ndi 372W kokha, 7% pansi pake adavotera.
Kuwala kwa chipale chofewa (zotsatira za albedo) kumawonjezeranso kulimbikitsa kwina: mawonekedwe a chipale chofewa amawonetsa kuwala kwa 80% -90%, pomwe nthaka wamba imangowonetsa 10% -20%. M'malo omveka bwino, ozizira, achisanu, zotulutsa zimatha kupitilira mphamvu zovotera ndi 18%.
Chifukwa Chimene Zimamveka Ngati Dzuwa Silipanga M'nyengo yozizira
Chifukwa sayansi ya zakuthambo imasintha. Pa latitude 42 ° N, tsiku la June limatenga pafupifupi maola 15, koma tsiku la December ndi pafupifupi 9. M'madera apakati pa latitude, mbadwo wachisanu wa mwezi uliwonse ndi 25% -50% wa July.
Kuti mudziwe zambiri: Germany ili pamtunda wa 50 ° N, ndipo mu 2023 pafupifupi 12% yamagetsi ake adachokera ku PV (Fraunhofer ISE). Kutalika kwakukulu sikutanthauza kuti PV ndi yosatheka - zimangotanthauza zofunikira zapamwamba.
Chipale Chofewa: Ndi Chipale Chomwe Mumasamalira, Osati Kuzizira
Linanena bungwe Muzosiyana Chipale Mikhalidwe
| Chipale chofewa | Zotulutsa | Nthawi yochira |
| Chipale chofewa (<2cm) | Translucent - akadali 50% -80% linanena bungwe | Mbali yamdima imatenga kutentha; zimasungunuka mu maola 1-2 |
| Kufikira pang'ono (~ 50%) | Amatsika mpaka 25% (chingwe chophimbidwa chimaletsa chingwe chonse) | Zimatengera nyengo |
| Kuphunzira kwathunthu | 0% | Ma Slide amazimitsa kapena akufunika kuchotsedwa pamanja |
| Zopanda chipale chofewa, zowoneka bwino komanso zozizira | 10% -18% pamwamba adavotera | — |
Zofunika Zapangidwe Zitatu
- Ngongole yopendekera ≥30°-40°: galasi losalala la galasi komanso kupendekeka kumapangitsa kuti chipale chofewa chizivunda chokha mkati mwa masiku 1-2 - palibe kuchotsa chipale chofewa pamanja pazochitika zambiri
- Kuchuluka kwa chipale chofewa ≥5400 Pa: kuchuluka kwa chipale chofewa cha ma module a Tier 1 - kumakhala pansi pa chipale chofewa popanda kupunduka
- Sankhani ukadaulo wa ma cell a N: kutentha kwapamwamba kwambiri kumatanthauza kuchepa kwachisanu
Malingana ndi ziwerengero za US NREL ndi PVPMC: zomera zambiri zimataya 0-10% ya m'badwo wapachaka ku chipale chofewa, ndipo choipitsitsa kwambiri m'madera omwe akugwa chipale chofewa ndi 10% -15%. Kuchotsa chipale chofewa pamanja nthawi zambiri sikuvomerezedwa - kuwonongeka kwa denga ndi kukwapula kwa module kumaposa mtengo wamagetsi womwe umapeza.
Malizitsani Mapangidwe Adongosolo a Mapulojekiti Apamwamba-Latitude
PV mbali
Kupindula kwa kutentha kwapansi ndi kwenikweni, komanso momwe masana amafupikitsa. Kukula kwa logic:
- Thamangani zachuma pa mbadwo wapachaka, osati nyengo yachisanu yokha
- Gwiritsani ntchito kusungirako usiku ndi masiku a chisanu / chipale chofewa; PV imakhala yofunika kwambiri masana
- M'madera omwe kulibe chipale chofewa, tsatirani njira yotsetsereka - sinthanitsani kuwala pang'ono kwa chilimwe kuti muwononge chipale chofewa.
Mbali Yosungira
| Chokonzekera | Malingaliro apamwamba kwambiri | Chifukwa |
| Chemistry ya batri | LFP (lithiamu iron phosphate) | Kugwira ntchito mpaka -20 ° C, moyo wautali wozungulira |
| Mphamvu njira | Kukula kwa nthawi yayitali kwambiri ya mafunde otsatizana / masiku achisanu | Kutalika kwapakati pakati pa recharge ya dzuwa m'nyengo yozizira |
| Kuwongolera kutentha | Insulated mpanda + Kutentha kasamalidwe | Kutsika kwa kutentha kumafuna kuwongolera kutentha |
Kufananiza Dizilo
Pansi pa -15 ° C, ma jenereta a dizilo amatha kukhala pachiwopsezo cha kutenthedwa kwamafuta, kuzizira kumafunika kutenthedwa, ndipo nthawi yosamalira imatha maola 250-500. Zima ndi nthawi yomwe dizilo imakhala yovuta kwambiri. PV + yosungirako combo ilibe vuto la gelling, ndipo mabatire osungira amakhalabe ndi mphamvu zotulutsa pa kutentha kochepa (LFP idavotera -20 ° C).
Kwa magetsi m'nyengo yozizira pamigodi yamtunda wautali, mtengo wonse wa njira ya dizilo (zoyendera mafuta + kukonza nyengo yozizira + kutsata kutulutsa mpweya) ziyenera kuwerengedwanso.
ZM-Besta's Cold-Climate Products
Malo opangira magetsi oyendera dzuwa a ZM-Besta amapangidwira kuti azigwira ntchito ndi kutentha kochepa:
| Parameter | Mtengo |
| Kutentha kwa ntchito | -20°C mpaka +50°C |
| Chitetezo pamene chatsekedwa | IP55 |
| Ukadaulo wama cell | N-mtundu TOPCon, kutembenuka kwachangu ≥22% |
| Kulimbana ndi mphepo pamene kutumizidwa | Beaufort Force 9 |
| Kusungirako mphamvu | LFP, yokhazikika ndi kukulitsa kosankha |
| Kutumiza | Kutumiza kwa njanji mu maola 4-20; kukula kwagalimoto mu ≤30 mphindi |
Zitsanzo zimachokera ku 20kW (chidebe cha 3.6m, chotsitsidwa ndi forklift) mpaka 150-200kW (chidebe cha 40ft). Ma projekiti m'madera ozizira amakonzedwa mwapadera pazinthu zitatu: kulimba kwamphamvu, kuchuluka kwa chipale chofewa, ndi kuwongolera kutentha kosungirako.
Kumbali yamapangidwe achitsulo: pamisonkhano yotalikirapo komanso malo osungiramo dome, zitsulo zimayikidwa kumagulu amphamvu a Q355D/S355J2 kutengera kutentha kochepa komweko, ndipo makina apadenga amapangidwa kuti azinyamula chipale chofewa. Mapangidwe apangidwe ndi kasinthidwe ka PV amatseka kuzungulira mkati mwa bungwe limodzi loyankha.
FAQ
Q1: Kodi ma solar angapangitse mphamvu zochuluka bwanji m'nyengo yozizira?
A: Zimatengera mitundu iwiri: latitude ndi matalala. M'madera apakati, nyengo yozizira mwezi uliwonse imakhala pafupifupi 25% -50% ya July; pamasiku omveka bwino, ozizira, opanda chipale chofewa, kutulutsa kwatsiku ndi tsiku kumatha kukhala 10% -18% pamwamba pa ovotera (kutsika kwa kutentha + chisanu). Ziwerengero zapachaka ndizomwe zimafunikira pazosankha zachuma.
Q2: Kodi PV ikugwirabe ntchito m'zigawo za -20 ° C?
A: Ma module amachita bwino kwambiri pakatentha kwambiri. Zomwe muyenera kutsimikizira ndikusintha kwadongosolo ladongosolo: kuwongolera kutentha kwa batri, kukwera kwa chipale chofewa, ndi kuzizira kwa chingwe. Malo opangira magetsi a ZM-Besta amaphimba -20°C mpaka +50°C.
Q3: Kodi matalala amafunika kuchotsedwa pamanja?
A: Nthawi zambiri ayi. Mitsuko yokhala ndi ngodya zopendekera pamwamba pa 30 ° imakhetsa chipale chofewa paokha mkati mwa masiku 1-2, ndipo kutayika kwa chipale chofewa pachaka kumakhala 0-10%. Zowopsa zachitetezo cha ntchito ndi kuwonongeka kwa module pakuchotsa pamanja nthawi zambiri zimaposa magetsi omwe adachira. Madera omwe ali ndi chipale chofewa mosalekeza ndi osiyana ndipo amafunikira njira yoyendetsera bwino ya chipale chofewa.
Q4: Kodi mumaphimba bwanji kuchepa kwa mphamvu yachisanu?
A: Kukula kwa LFP kosungirako kwa nthawi yayitali kwambiri yotsatizana ya chisanu/chipale chofewa. PV imakhala yofunika kwambiri masana, kusungirako kumaphimba usiku, ndipo zida za dizilo zimasungidwa ngati zosunga zobwezeretsera nyengo yoipa - ndiye njira yosakanizidwa yomwe migodi imagwiritsa ntchito kwambiri.
Q5: Kodi ubwino wa N-type TOPCon ndi wofunika bwanji m'nyengo yozizira?
A: Kutentha kwake kumakhala pafupifupi -0.25% mpaka -0.30% / ° C, kutaya 0.05% -0.1% kuchepera pa digiri ya PERC wamba. Kutentha kocheperako kumakulirakulira pa -20 ° C, motero mtundu wa N umapereka kutulutsa kokhazikika pakazizira kwambiri.
Mukufuna kukulitsa m'badwo wachisanu ndi kusungirako projekiti yanu yotalikirapo?
