Yiziphi Izakhi ze-Rooftop Solar Photovoltaic Systems?

Ngokusekelwe ezinhlosweni zokungathathi hlangothi kwekhabhoni emhlabeni jikelele, Uphahla lwe-solar photovoltaic (PV) system ukufakwa kuyaqhubeka ukwanda. Ukufakwa kwe-photovoltaic esatshalaliswa emhlabeni wonke kuma ku-120 GW ngo-2023, lapho kwafakwa khona ngaphezu kuka-58% ophahleni lwezindlu, ngokusho kwedatha evela ku-International Renewable Energy Agency (IRENA). Lezi zinhlelo ezididiyelwe zokuphehla amandla, ukugcinwa, kanye nokusetshenziswa kwamandla ziguqula umkhakha wamandla ngenxa yezakhiwo zazo eziyisisekelo kanye nobuchwepheshe. Ngakho-ke, luyini uhlelo lwe-PV ophahleni lwelanga? Ake sithole ngokuningiliziwe.

Izingxenye Eziyinhloko ze-Rooftop PV Systems

1.Amamojula we-Photovoltaic

Njengomgogodla omaphakathi wesistimu, amamojula we-photovoltaic ahlangabezane nezizukulwane ezintathu zokuthuthukiswa kobuchwepheshe:

Amamojula we-Crystalline Silicon esizukulwane sokuqala

I-Monocrystalline PERC (I-Passivated Emitter ne-Rear Cell): Ukusebenza kahle kokukhiqiza okuningi kusuka ku-22.5% kuya ku-24.8%.

I-Polycrystalline Silicon: Ukusebenza kahle kuhluka kusuka ku-17% kuya ku-19.6%, ngezindleko eziphansi ezicishe zibe ngu-¥0.3 ngewathi ngayinye.

Amamojula Efilimu Encane Yesizukulwane Sesibili

I-CIGS (I-Copper Indium Gallium Selenide): Ifaka ukuguquguquka, iyenze ifanelekele izinhlelo zokusebenza ezihlanganisiwe zokwakha ezifana nama-facade.

I-Perovskite: Ukusebenza kahle kwelabhorethri kudlule ku-33.7%, okubonisa amandla abalulekile okuthengisa esikhathini esizayo.

I-Third-Generation Composite Technologies

Amaseli e-HJT (Heterojunction): Ziqhayisa ngezinga elikabili lama-95% kanye nezinga lokuwohloka lonyaka elingaphansi kuka-0.25%.

I-TOPCon (I-Tunnel Oxide Passivated Contact) Amamojula: Finyelela ukuphuma kwamandla akhiqizwe ngobuningi angaphezu kuka-700W+, wehlise I-Levelized Cost of Energy (LCOE) ngo-12%.

Encapsulation Breakthroughs

Amamojula Engilazi Ekabili: Anikeza ukumelana nesimo sezulu okuphindwe kathathu kwamamojula avamile, anweba ukuphila kwawo kokusebenza kuya eminyakeni engu-35.

Amamojula Ahlakaniphile: Ahlanganiswe nama-chips okuthuthukisa, lawa mamojula athuthukisa ukukhiqizwa kwamandla kwephaneli elilodwa kufika ku-20%.

2.Ama-Inverters

Ubuchwepheshe be-Inverter buyashintsha ngezindlela ezintathu ezibalulekile:

3.Amasistimu Wokugcina Amandla (Ongakukhetha)

Kuzinhlelo ze-PV ezisophahleni lwegridi, indawo yokugcina amandla ivumela ukusetshenziswa kukagesi ebusuku. Izinhlobo zebhethri ezijwayelekile zifaka:

I-System Architecture kanye nokuphathwa kwamandla

1.Ukuqhathanisa Izinhlobo Ezintathu Zesistimu

2.Amasistimu Okulawula Okuhlakaniphile

Isendlalelo se-Hardware

Izinzwa Zemvelo: Hlala uqapha i-irradiance, izinga lokushisa le-ambient, nesivinini somoya.

Imizila Yamandla: Phatha ukulinganisa kwamandla kuma-microgrid e-DC ukuze uqinisekise ukusebenza okuzinzile.

Isendlalelo Sesoftware

I-Algorithms Yesitoreji Samandla Nokusabalalisa: Yabela ngobuhlakani amandla agciniwe ukuze ukhulise ukusebenza kahle kokusetshenziswa.

I-Real-Time Monitoring & Analytics Platforms: Nikeza ngemininingwane ebanzi yokusebenza kwesistimu, okuvumela ukulungiswa okusebenzayo.

I-Remote Control Interfaces: Vumela ukulawula amasistimu ngokusebenzisa izixhumanisi ezisuselwe emafini noma izinhlelo zokusebenza zeselula.

Izakhiwo zokukhweza Nezesekeli

1.AmaRakhi Okufakwayo

Ama-racks abalulekile ekuqiniseni amaphaneli e-PV aqine ophahleni. Zidinga amandla aphezulu emishini kanye nokumelana nokugqwala ukuze zimelane nezimo zezulu ezinzima. Izikhwezi ezilungisekayo zithatha izinhlobo zophahla ezihlukene (isb., ezitshekile, eziyisicaba) kanye nokuma kwazo futhi zandise ama-engeli anyakazayo wephaneli ukuze kubanjwe ubuningi bokukhanya kwelanga.

2.Amakhebuli nama-Sealants

Amakhebuli: Amakhebuli aqinile, amelana ne-UV anikeza ukudluliswa kwamandla okuphumelelayo phakathi kwezingxenye ezinokuncipha kwamandla aphansi.

Ama-Sealants: Ama-Elastomeric waterprooof sealants agcwalisa indawo engaphezulu ye-module frame-glass surface futhi akubandakanyi umswakama, andisa impilo yemojuli.

Izingxenye ezingeziwe

1.Amadivayisi okuvikela umbani

Kutholwe ukuze kuvikeleke amasistimu kuma-voltage spikes okubangelwa umbani, futhi kuvimbele ukulimala kwemishini kanye nengozi yomlilo.

2.Izisetshenziswa Zokuvikela Isekethe

Ama-Circuit Breaker: Anqamule amandla ngokuzenzakalelayo ekulayisheni ngokweqile noma kumasekethe amafushane.

Ukudluliselwa: Khipha amandla amasekhethi anephutha ukuze uvikele isistimu nabasebenzisi bokugcina.

Amasistimu Okuqapha Ukusebenza

Ama-Data Logger: Irekhodi eliqhubekayo lamapharamitha afana ne-voltage, yamanje, namandla aphumayo.

Isofthiwe Yokuthola Amaphutha: Sebenzisa ama-algorithms asekelwe emshinini ukuze uhlonze okudidayo (isb, ukucekelwa phansi kwephaneli, izinkinga zokufiphaza) ngesikhathi sangempela.

Ukusuka kumaphaneli e-silicon e-monocrystalline kuya kuma-microgrid ahlakaniphile, ukufakwa kwe-PV ophahleni kuyashintsha kusuka "kumajeneretha wamandla" azimele kuya "kuzindawo zamandla" ezihlanganisiwe. Njengoba ubuchwepheshe buqhubeka buthuthuka-kungakhathaliseki ukuthi ukuhweba kwe-perovskites, ukuphathwa kwamandla aqhutshwa yi-AI, noma umnotho wesilinganiso kumabhethri e-lithium-ion-solar sophahla lusethelwe ukuba lube "impahla eluhlaza" yonke indawo yamabhizinisi kanye nabathengi ngokufanayo, ukuletha kokubili ukusimama kwemvelo kanye nembuyiselo yezomnotho yesikhathi eside.
