1.Conversion efficiency

η= Pm (lub zog siab tshaj plaws ntawm lub xov tooj ntawm tes) / A (chaw ntawm lub xov tooj ntawm tes) × Pin (qhov xwm txheej lub teeb hluav taws xob hauv ib cheeb tsam)

Ntawm lawv: Pin =1KW/㎡=100mW/cm².

2. Kev them nqi hluav taws xob

Vmax=V nyiaj x 1.43 x

3. Cov khoom siv roj teeb tau txuas nrog hauv cov koob thiab sib luag

3.1 Tus naj npawb ntawm cov roj teeb modules txuas nyob rau hauv parallel=Txhua hnub siv hluav taws xob nruab nrab ntawm lub nra (Ah) / Nruab nrab txhua hnub lub zog tsim hluav taws xob ntawm module (Ah)

3.2 Tus naj npawb ntawm cov roj teeb modules hauv series=kev khiav hauj lwm voltage (V) × coefficient 1.43/module peak operating voltage (V)

4. Roj teeb muaj peev xwm

Roj teeb muaj peev xwm=Nruab nrab lub zog noj ib hnub load (Ah) × Tus naj npawb ntawm cov hnub los nag sib law liag / Qhov siab tshaj plaws ntawm qhov tso tawm

5.Qhov nruab nrab tawm tus nqi

Qhov nruab nrab tawm tus nqi (h)=tus naj npawb ntawm cov hnub los nag sib law liag × lub sijhawm ua haujlwm thauj khoom / qhov tso tawm qhov tob tshaj plaws

6. Lub sijhawm ua haujlwm

Load ua hauj lwm lub sij hawm (h)=∑ load zog × load ua hauj lwm lub sij hawm / ∑ load zog

7. Roj teeb

7.1 Roj teeb muaj peev xwm=nruab nrab load hwj chim noj (Ah) × tus naj npawb ntawm rainy hnub sib law liag × tawm kho coefficient / siab tshaj tawm qhov tob × tsis tshua muaj kub kho coefficient

7.2 Tus naj npawb ntawm cov roj teeb hauv series=qhov system khiav hauj lwm voltage / roj teeb nominal voltage

7.3 Tus naj npawb ntawm cov roj teeb sib txuas hauv qhov sib npaug=tag nrho cov roj teeb muaj peev xwm / roj teeb nominal peev
