Ntev npaum li cas thiaj li rov qab tau cov nqi hluav taws xob photovoltaic ntawm 500㎡ ru tsev?

(1) Lub zog ntawm ib qho PV module tuaj yeem ncav cuag ntau dua 500 watts, thiab thaj tsam li ntawm 2.5㎡ (2.2m * 1.13m), uas yog sib npaug rau 200 watts ib square meter. Raws li lub tiaj tus installation, theoretically, 500㎡ lub ru tsev tuaj yeem ntsia tau nrog 100-kW PV vaj huam sib luag;

(2) Xav txog lub kaum sab xis ntawm kev teeb tsa, qee thaj chaw tuaj yeem txuag tau, thiab thaj chaw khaws cia tuaj yeem siv los ua kev saib xyuas, yog li qhov tseeb 500㎡ lub ru tsev tuaj yeem ntsia tau nrog 100-kW PV vaj huam sib luag.

Piv txwv li: qhov nruab nrab hnub ci hnub ci txhua xyoo rau kev tsim hluav taws xob photovoltaic hauv ib qho chaw yog li 1029 teev. Txij li thaum 100-kilowatt photovoltaic vaj huam sib luag tuaj yeem tsim 100kwh ntawm hluav taws xob ib teev, lub zog txhua xyoo yog li 100kwh/hour * 1029 teev=102900 degrees=103,000 kWh. Xav tias photovoltaic grid-connected inverter muaj li 3% poob, tag nrho lub zog tsim muaj txog 100,{11}} kWh.

Raws li kev tsim kho tus nqi kwv yees li $ 430 ib kilowatt ntawm photovoltaic fais fab tiam, tus nqi ntawm 100 kW ntawm photovoltaic fais fab tuag yog kwv yees li $ 430 / kW * 100 kW=$ 43,000.

(1) Xav txog tus nqi hluav taws xob nruab nrab txhua hli: Raws li tus nqi hluav taws xob ntawm lub tuam txhab cov nqi hluav taws xob, tus nqi hluav taws xob txhua hli yog kwv yees li $0.14 ib kWh;

(2) Xav txog tus nqi hluav taws xob nruab nrab raws li cov sij hawm siab tshaj plaws thiab cov sij hawm off-peak: 8:00-11:30 yog lub sij hawm siab tshaj (cov nqi hluav taws xob yog kwv yees li $0.15/kWh ), thiab 11:30-18: 30 yog lub sijhawm tsis muaj zog (tus nqi hluav taws xob yog kwv yees li $0.1/kWh).

Kev suav cov cai:

Txij li thaum lub zog hluav taws xob photovoltaic yog nqa tawm thaum nruab hnub, cov nqi hluav taws xob txuag tau los ntawm kev tsim hluav taws xob tuaj yeem tsuas yog sib npaug rau qhov nruab nrab tus nqi ntawm lub ncov thiab lub sijhawm tiaj tus. Tus nqi hluav taws xob txuag los ntawm kev tsim hluav taws xob photovoltaic thaum nruab hnub yog ({{0}}.83)/2=0.92RMB(0.13USD)/kwh.

Lub sijhawm them rov qab:

Cov nyiaj tau los tsim hluav taws xob txhua xyoo yog 100,000 kwh*0.92=92,000 RMB(13,000USD), thiab cov peev nyiaj rov qab lub sijhawm yog 30/9.2=3.26 xyoo.
