Abaphandi baseJamani iFrauhofer ISE bahlalutye ukusebenza kwempompo yobushushu yendawo yokuhlala eqhagamshelwe kuphahla lwePV inkqubo exhomekeke kugcino lwebhetri kwaye bafumanise ukuba le ndibaniselwano iphucula kakhulu ukusebenza kwempompo yobushushu ngelixa ikwanyusa kakhulu izinga lokuzisebenzisa lelanga.
Iqela labaphandi baseJamani iFraunhofer Institute for Solar Energy Systems (iFraunhofer ISE) iphande ukusebenza kweempompo zobushushu ezilungele igridi (HPs) ezidityaniswe nombane welanga ophahleni kunye nokugcinwa kwebhetri kwizindlu zentsapho enye kwaye zafumanisa ukuba zombini ii-PV arrays kunye neebhetri zinokuphucula kakhulu ukusebenza kweempompo zobushushu.
Ii-HP ezilungele igridi ehlakaniphile zinokucinywa ngumsebenzi wegridi ngexesha lomthwalo wegridi ephezulu. Bakwanikezela ngenzuzo yokwandisa ukusetyenziswa kwe-PV ngokulungelelanisa ukusebenza kwabo ngokusekelwe kumandla akhoyo elanga.
"Imowudi elungele igridi ye-smart iyasebenza xa ibhetri itshajiswe ngokupheleleyo okanye itshaja ngamandla ayo aphezulu kwaye kusekho i-PV surplus ekhoyo," izazinzulu zatsho, ziphawula ukuba ii-HPs ezilungele igridi ezinokulungelelanisa ukusebenza kwazo ngendlela ejolise kwigridi. "Ngokwahlukileyo, imeko yokuqalisa idibene xa amandla e-PV ngokukhawuleza ehlala ephantsi kunesidingo esipheleleyo sokwakha ubuncinci be-10 min."
Izifundiswa zihlalutye, ngokukodwa, ukusebenza kwenkqubo ye-PV-HP isebenzisa idatha ye-1 yemizuzu yesisombululo sendawo ukusuka kwi-semi-detached, indlu yentsapho eyodwa eyakhiwe ngo-1960 eFreiburg, ezantsi kweJamani. Indlu inemfuno yokufudumeza yonyaka eyi-84.3 kWh/m² kunye nendawo yokuhlala eshushu eyi-256 m.2.
Uhlalutyo lwabo luqwalasele indlela ulawulo olulumkileyo olusetyenziswe ngayo kwi-solar-plus-storage system inokuchaphazela ukusebenza kwempompo yokushisa. Bathathele ingqalelo izalathisi eziphambili zokusebenza (KPIs) ezifana nezinga lokuzityela, iqhekeza lelanga, ukusebenza kwexesha lonyaka, kunye nejika lokufudumeza. "Kunokuba luncedo ukuvavanya ukusebenza kwempompo yokushisa kuphela umbane osetyenzisiweyo kwigridi," bachaza. "Le ndlela isekelwe kwingcinga yokuba umbane oveliswa yi-PV yasekhaya kunye neeyunithi zebhetri zikhululekile kubanikazi bezindlu."
Ulungelelwaniso lwenkqubo ecetywayo lubandakanya i-13.9 kW yempompo yobushushu bomthombo womhlaba olungiselelwe ukufudumeza indawo kunye namanzi ashushu asekhaya (DHW), inkqubo ye-PV ejolise kumzantsi ye-12.3 kW ene-angle ethambekileyo ye-30 degrees, i-12 kW inverter, kunye nebhetri edibeneyo ye-DC enomthamo we-11.7 kWh.
Uhlalutyo lubonise ukuba inkqubo ye-PV-HP yakwazi ukufezekisa izinga lokuzityela eliqhelekileyo le-42.9% ekuhambeni konyaka, kunye nezona ziphakamileyo zifikeleleke ebusika. "Ngokwahlukileyo, i-PV ephezulu ye-surplus ikhokelela ekunciphiseni ukusetyenziswa kwe-self-ehlotyeni, ngokuqhelekileyo ngexesha lokukhanya kwelanga," iqela lophando lachaza. “Ibhetri enkulu iya kunceda ekwandiseni ukusetyenziswa kwebhetri; nangona kunjalo, oku kukwathetha ukuba uninzi lomthamo webhetri luya kushiywa lungasetyenziswa ngexesha leenyanga zasebusika ngamandla ashiyekileyo ePV.
Oosonzululwazi baphinde bafumanisa ukuba inkqubo yogcino lwelanga kunye ne-solar yakwazi ukugubungela malunga ne-36% yemfuno yombane yempompo yobushushu. "Ngenxa yobushushu obuphezulu be-sink, ukusebenza kakuhle kwe-HP kuyancipha nge-5.7% kwimodi ye-DHW kunye ne-4.0 % kwimodi yokufudumeza kwendawo," baphinde bachaza. "Iziphumo zibonise ukuba ngokuqwalasela umbane we-PV onikezelwe kwimpompo yokushisa, ixesha lokusebenza kwexesha liye lanyuka ukusuka kwi-4.2 ukuya kwi-5.2. Xa unikezelo oludityanisiweyo olusuka kwi-PV kunye nebhetri ukuya kwimpompo yobushushu kwaqwalaselwa, ukusebenza kwexesha lonyaka kwanda ukuya kwi-6.7.
Baye baqaphela, nangona kunjalo, ukuba ulawulo oluhlakaniphile lunokuchaphazela kakubi ukusebenza kwempompo yobushushu ngenxa yokunyuka kwamaqondo okushisa. "Uvavanyo lwexesha elide kwinqanaba lenkqubo, ngokuqwalasela umphumo welahleko yokugcina kunye nokuqwalasela ukusebenza kwezoqoqosho kunokuvavanya kakuhle umphumo wokulawula okuhlakaniphile kwinkqubo," baphetha.
Iziphumo zabo zifumaneka kwisifundo "Uhlalutyo lwentsebenzo kunye nokusebenza kwenkqubo yempompo yokushisa yebhetri ye-photovoltaic-ibhetri esekelwe kwidatha yokulinganisa intsimi," epapashwe Ukuqhubela phambili kwamandla eSolar.
