Ukuhlelwa kweSistimu esiyinhloko yeSolar-Plus-Storage: Umkhawulo nokuhlelo
Ukuhlelwa kwezinto ngokulingana nezidingo zokugcinwa kanye nezimo zokudla
Ukuhlelwa kwezinhlelo yokunqamula imithwako yasolari ngekugcinwa kwezinhlanzi kufanele kube ngokuhlanganisa nokubheke kahle kwezindleko zokusebenzisa imithwako. Indlu ebalulekilekile ePhakathi kwe-Amerika isebenza ngokuphelele kwe-893 kWh nginyanga, ake kweqile kakhulu isikhangiso sibeke 5,000 kWh noma ngaphezulu. Ngokukhangela amabhili wokusebenzisa imithwako noma ukusebenzisa amathimba amakhani, abasebenzisi bakwazi ukufind outimes of peak usage, daily kWh requirements, and seasonal variations—critical data for sizing both PV panels and batteries.
Kwiimfanelo zokuphatha izilulu, okuphambene kakhulu kuyindlela yokufanisa ukuphuma nokudinga kwezindleko. Imijoli yamagetsi engu-6 kW (ngokwengeza ama-18–20 imijoli) iyenza ama-9,000 kWh ngonyaka emaqandini amancane njenge-Arizona, noma kunjalo le ndawo engu-6,000 kWh ezingeni eliphezulu kwezilulu njenge-Pacific Northwest. Ikhapasiti yebhati, ibalwe kwi-kilowatt-iintshi (kWh), kufanele ibe yinhamba yokufakwa kwi-1–2 intloko zokudlula ngokudla ukuthintela ukuba kunezidingo zokugcina xa kungena iphulekisi. Isibonelo, indlu enyeza ama-30 kWh kwinye yentloko kuya kufuna imijoli yebhati engu-40–60 kWh, iyaziwa ukuba kukhokelela kwezifayo (okungenani 10–15% kwiqondo lokuvelisa nokulayisha).
Ukucwangcwa kwe nhloso kuyindlela yokwenza. Izinhloso zokuxhuma kwe AC, lapho izibhande zixhuma kwekankanya ye-inverter AC, zilula ukulandelwa kwezinhloso zasekhanda zokushisa. Izinhloso zokuxhuma kwe DC, ezixhuma izibhande ngqo kwekankanya ye DC yezinhloso zokushisa, zinobunconywa (ngama-5–10%) kuzindlela zokubhala, njengoba kubalulekile ukungena kwezindlela zokuguqula amandla. Ngokudonsela, izinkankanyo zokuxhuma—ezivumelana nezinkankanyo zokushisa nezinhloso zokuphatha izibhande—zilula ukufakwa futhi kuvumela ukutholwa kwezinhloso, ukuthiwa amandla aphumelele phakathi kwezinhloso, izibhande, ne-gridi.
Imigomo ezingcono kanye nezinto eziphatha ukulingana kwegable, ukubonwa kwezulu kanye nezulu kufanele kucinywe. Iipaneli eziphatha kuyo ntshonalanga (kwiNkantolo yekhanda elingeneyo) zenza ukuba kuthathwe ngcono kwezulu, ngelixa iindlela zokulaka kufanele zilindele kwi-latititi yendawo (umzekelo, 30-40 amadigri kwiindawo eziphezulu zase-US). Kizindaweni ezinginemvula, iindlela engeyokubona kwezulu kunye neemeko eziphezulu zinezulu zinezulu zokuthathwa kwezulu, zinezulu zokugcina. Kwiibhatteri, ukuvila kwehlu kanye nokulawulwa kwezulu (okungenjalo 20-25 ° C / 68-77 ° F) kugcinela ukuba kweyona, ukuthi zikhumbule 80% yazo ngemva kwezingu 10 kanye nezingu ezininzi. Ngokwenza uhlelo olulodwa kule ndawo, abasebenzisi bakhona ukuba kuthathwe ngcono kwezulu kunye nokugcinwa ngemfanelo.
