Piv txwv ntawm Lub Tsev Photovoltaic Capacity Calculation

Piv txwv ntawm lub ru tsev photovoltaic muaj peev xwm xam

1. Muaj peev xwm suav nrog

Kev suav lub peev xwm ntawm lub ru tsev photovoltaic tej yaam num yuav tsum xav txog ntau yam, nrog rau lub ru tsev cheeb tsam, lub teeb pom kev zoo, photovoltaic module efficiency, installation lub kaum sab xis, thiab lwm yam.

1.1 thaj tsam ru tsev

Ntsuas thaj tsam ntawm lub ru tsev: Siv cov drones, laser rangefinders, los yog daim phiaj xwm los ntsuas qhov muaj nyob ntawm lub ru tsev.

Tshem tawm cov teeb meem: Tshem tawm qhov chaw nyob ntawm cov teeb meem ntawm lub ru tsev (xws li chimneys, qhov cua qhib, cua txias sab nraum zoov, thiab lwm yam).

1.2 Cov khoom siv teeb pom kev zoo

Tau txais cov ntaub ntawv teeb pom kev zoo: Tau txais qhov nruab nrab hnub ci hluav taws xob hauv zos txhua xyoo (kWh / m ² / hnub) los ntawm cov chaw nres tsheb huab cua lossis hauv online platforms.

Xav txog kev hloov pauv raws caij nyoog: Lub teeb siv lub caij ntuj no thiab lub caij ntuj sov yog qhov sib txawv, thiab cov nqi nruab nrab txhua xyoo yuav tsum tau muab rau hauv tus account.

1.3 Photovoltaic module efficiency

Xaiv hom kev tivthaiv: Xaiv monocrystalline silicon, polycrystalline silicon, los yog nyias-zaj duab xis Cheebtsam raws li qhov yuav tsum tau ua.

Cheebtsam lub zog: Xaiv lub nominal zog (Wp) ntawm cov khoom.

1.4 Kev teeb tsa lub kaum ntse ntse thiab kev taw qhia

Qhov zoo tshaj plaws inclination lub kaum sab xis yog feem ntau ± 10 degree ntawm lub zos latitude.

Kev taw qhia: Sab qab teb yog qhov zoo tshaj plaws, ua raws li sab hnub tuaj thiab sab hnub poob, thiab sab qaum teb yog qhov phem tshaj.

1.5 System poob

Kev kub ntxhov: Kev kub siab tuaj yeem txo cov hluav taws xob tsim hluav taws xob ntawm cov khoom siv.

Duab ntxoov ntxoo cuam tshuam: Duab ntxoov ntxoo ntawm lub ru tsev tuaj yeem cuam tshuam rau kev tsim hluav taws xob.

Hluav taws xob poob: poob ntawm inverters, cables, thiab lwm yam.

2. Muaj peev xwm suav cov mis

Lub cev muaj peev xwm (kW)= Muaj cheeb tsam ru tsev (m2) x Cov khoom siv hluav taws xob ntom ntom (W/m2) 1000 Qhov system muaj peev xwm (kW)=1000 Muaj thaj chaw ru tsev (m2) x Cov khoom siv hluav taws xob ntom ntom (W / m2 )

Ntawm lawv, lub zog ceev ntawm cov khoom yog xam raws li lub zog nominal thiab qhov loj ntawm cov khoom.

3. Cov piv txwv

3.1 Project Background

Ru tsev hom: ru tsev tiaj tus

Thaj Chaw: 1000 m²

Lub hnub ci hluav taws xob nruab nrab txhua xyoo: 4.5 kWh / m² / hnub

Yam khoom: monocrystalline silicon tivthaiv

Lub cev muaj zog: 350 Wp

Cov khoom loj: 1660mm × 992mm

Component efficiency: 18%

Lub kaum sab xis installation: 20 degree

Kev taw qhia: Southward

3.2 Cov kauj ruam suav

Xam cov cheeb tsam

Luas=66 m x 0.992 m =1.64672 m2

Xam cov khoom siv zog ceev

Lub cev muaj zog ntom ntom =350 Wp1.64672 m2 ≈ 212.5 W / m2

Xam cov naj npawb ntawm cov khoom muaj

Tus naj npawb ntawm cov khoom muaj nyob hauv=thaj chaw muaj ru tsev Component cheeb tsam =1000 m2 1.64672 m2 ≈ 607 pieces

Xam qhov muaj peev xwm

Lub cev muaj peev xwm =ntau ntawm cov khoom muaj x cov khoom siv fais fab=607 blocks x 350 Wp=212450 Wp ≈ 212.45 kWp

Xav txog qhov kev poob

Kub cuam tshuam: Piv txwv li 5% txo

Duab ntxoov ntxoo cuam tshuam: Piv txwv tias txo qis 3%.

Hluav taws xob poob: Piv txwv tias txo 2%.

Lub cev muaj peev xwm tiag tiag =212.45 kWp × (1-0 05-0.03-0.02) ≈ 192.6 kWp

3.3 Cov txiaj ntsig

Lub cev muaj peev xwm: 192.6 kWp

Kev kwv yees tsim hluav taws xob txhua xyoo:

Kev tsim hluav taws xob ib xyoos ib zaug=System muaj peev xwm x Ib xyoos ib zaug nruab nrab hnub ci hluav taws xob x 365 Kev tsim hluav taws xob ib xyoos ib zaug=System muaj peev xwm x Ib xyoos ib zaug nruab nrab hnub ci hluav taws xob x 365

Kev tsim hluav taws xob txhua xyoo =192.6 kWp × 4.5 kWh/m2/day × 365 hnub ≈ 316000 kWh/xyoo
