Kungani abasebenzisi bezentengiselwano nabezimboni baya ngokuya bethanda i-solar ephezu kophahla?

Njengoba amanani kagesi enyuka kancane, amabhizinisi abhekana nengcindezi ekhulayo ezikweletini zawo zikagesi unyaka nonyaka. Ngasikhathi sinye, ngaphansi kwezinhloso ezimbaxambili zekhabhoni, ukuguqulwa kwekhabhoni eluhlaza kanye nekhabhoni ephansi sekuyimpoqo. Inani elikhulayo lamabhizinisi ligxilisa ukunaka kwawo ezinhlelweni zamandla elanga asophahleni - imodeli enganciphisi kakhulu kuphela izindleko zikagesi kodwa futhi enciphisa ukukhishwa kwekhabhoni futhi ilolonge isithombe somkhiqizo oluhlaza. Iqhutshwa kokubili inqubomgomo kanye namandla emakethe, le ndlela ithola ukuthandwa ngokushesha.

Okuphawuleka nakakhulu, ukuhlanganisa ama-photovoltaics nesitoreji samandla kukhulisa lezi zinzuzo: ukusebenzisa amandla elanga phakathi namahora okukhanya kwasemini kanye nokukhipha amandla agciniwe ebusuku kufeza 'isizukulwane sakho sokuzithengela ngokwakho kanye nesitoreji esiningi'. Le modeli ivela njengesixazululo esithandwayo esivuselelekayo samafekthri, amapaki ezimboni, izakhiwo zezentengiselwano kanye nezilungiselelo ezifanayo.

I-PV Yophahla Oluphezulu: Ithuluzi Elinamandla Lokunciphisa Izindleko

Emabhizinisini okukhiqiza, izindleko zikagesi ngokuvamile zenza u-10% -30% wezindleko zokusebenza. Inzuzo yophahla lwe-PV isekundleni kwayo ukusebenzisa indawo yophahla lwefekthri engenzi lutho ukukhiqiza ugesi, ukunciphisa ukuthembela kugridi. Uma sithatha ifekthri engu-10,000-square-metres njengesibonelo, ukufaka isistimu ye-PV kungakhiqiza cishe isigidi esingu-1 kWh ngonyaka. Ngesilinganiso sikagesi wezimboni esingu-¥0.8 kWh ngayinye, lokhu kusho ukonga konyaka okungafika ku-¥800,000.

Umgomo wokusebenza wezinhlelo ze-photovoltaic uqondile: amaphaneli elanga amunca ukukhanya kwelanga ukuze akhiqize amandla akhona aqondile (DC), aguqulelwe ekubeni i-alternating current (AC) yi-inverter ukuze ahlanganiswe kunethiwekhi yokusabalalisa yebhizinisi. Ukwamukela imodeli 'yokuzenzela wena ngokwakho, ukuphakela ngaphakathi kwe-surplus' kuqinisekisa ukuthi ugesi ubekwa kuqala ukuze usetshenziswe yibhizinisi ngokwalo, namandla engeziwe abuyiselwa kugridi ukuze kwandiswe izinzuzo zomnotho.

Izinzuzo zokutshalwa kwezimali ziyavezwa, nezinzuzo ezinkulu zesikhathi eside

Izindleko zamanje zokutshala izimali zezinhlelo ze-PV zophahla lwezentengiselwano zisukela cishe ku-3.5 ukuya ku-4.5 yuan ngewathi ngayinye. Uma sithatha iphrojekthi engama-kilowatt angu-500 njengesibonelo, isamba sokutshalwa kwezimali silinganiselwa ku-1.75 kuya ku-2.25 million yuan, okwenza ukonga ugesi ngonyaka cishe okungamayuan angu-400,000. Isikhathi sokukhokha ngokuvamile sisukela eminyakeni emi-4 kuye kweyisi-6. Njengoba kunikezwe ukuthi amasistimu e-photovoltaic anesikhathi sokuphila esingaphezu kweminyaka engu-25, lokhu kusho ukuthi ngemva kokubuyisela utshalomali lwawo, amabhizinisi angajabulela cishe iminyaka engamashumi amabili 'kagesi obiza kancane noma wamahhala.' Le nzuzo yesikhathi eside ibonakala ikakhulukazi ngokukhuphuka kwamanani kagesi.

Ukuthuthukiswa Kwesitoreji Samandla: Ukukhulisa Inani Le-Photovoltaics

Ukuhlukahluka kwezimo zokusetshenziswa kukagesi ebhizinisini kusho ukuthi imodeli eyodwa yokukhiqiza i-photovoltaic ngeke isakwazi ukuhlangabezana nazo zonke izidingo, ikakhulukazi kumabhizinisi anemithwalo ebalulekile yasebusuku. Ezimweni ezinjalo, ukuhlanganisa amasistimu okugcina amandla kuba semqoka ekuthuthukiseni izakhiwo zokusetshenziswa kwamandla.

Thatha iphrojekthi e-Ganzhou, eSifundazweni sase-Jiangxi njengesibonelo: ifekthri yasendaweni yasebenzisa uphahla lwezakhiwo eziyi-12 ukuze kwakhiwe isiteshi sikagesi se-PV esisatshalaliswayo esinamandla acishe abe ngu-2.8 MWp. Lokhu kwahambisana nohlelo lokugcina amandla angu-1 MW/2.15 MWh, oluhlanganisa amakhabethe ethu okugcina amandla apholile angu-10 angu-215 kWh. Uma usuphothuliwe, kulindeleke ukuthi lo msebenzi wonge ugesi olinganiselwa ezigidini ezi-3 kWh ngonyaka, unciphise umfutho kagesi wenkampani kuyilapho kuzuzwa ukuncipha kwezindleko kanye nezinzuzo ezisebenza kahle.

Imishini yokugcina amandla ye-HJ Group ibonise ukusebenza okumangalisayo kule phrojekthi. Amakhabethe ayo okugcina apholile emoyeni anikeza izinzuzo ezihlanganisa ukuphepha okuphezulu, ukuhlakanipha, nokwethembeka. Abagcini nje ukunika amandla ukuthunyelwa okuguquguqukayo kwamandla we-photovoltaic kodwa futhi nokuguquguquka kwamandla okushelelayo, okuqinisekisa ukusebenza okuzinzile kwemishini yokulayisha. Ngaphezu kwalokho, idizayini yomkhiqizo ibeka kuqala ukunethezeka nokulungisa izinto zibe lula ezilungiselelweni zezimboni, uthole udumo olusabalele kubasebenzisi bebhizinisi.

Izinzuzo Eziningi: Ukonga Amandla, Ukuvikelwa Kwemvelo, kanye Nokuthuthukiswa Kwebhrendi

Ngaphandle kokwehliswa kwezindleko zikagesi okuqondile, ukufakwa kwe-PV ophahleni kuletha inani elengeziwe. Isibonelo, amaphaneli e-photovoltaic ahlinzeka ngokufakwa kokushisa okushisayo, ehlisa izinga lokushisa lasembonini ngo-3-5°C phakathi nezinyanga zasehlobo futhi anciphise ukusetshenziswa kwamandla esimoyeni. Ngaphezu kwalokho, ukwamukela amandla aluhlaza kusiza amabhizinisi ukuthi ahlakulele isithombe esinekhabhoni ephansi, esikhathalela imvelo - inzuzo ebalulekile kumaketanga anamuhla wokuphakelwa komhlaba lapho ukucatshangelwa kwe-ESG (Environmental, Social, and Governance) kuya ngokuya kubaluleke kakhulu.

Amabhizinisi amaningi aphinde ahlanganise amasistimu okuqapha ukuze alandelele ukukhiqizwa nokusetshenziswa kwamandla ngesikhathi sangempela, ngamakhono okuqagela avumela ukuhlela amandla athuthukisiwe. Ukufakwa kwezinhlelo zokugcina amandla kwenza 'izixazululo ezihlanganisiwe ze-photovoltaic-storage' zibe ukukhetha okuhle kubasebenzisi bezentengiselwano nabezimboni. Amabhizinisi aseShayina okugcina amandla afana ne-HJ Group anika laba basebenzisi amandla okufinyelela izinjongo ezimbaxambili zokushintsha kwamandla nokuthuthukisa izindleko ngezixazululo zomkhiqizo ezisebenza kahle, ezivikelekile nezihlakaniphile.

Ukuze uthole imininingwane eyengeziwe ngemikhiqizo yethu yokugcina amandla, sicela ukhululeke ukubuza!
