Wani project ya ke da 8kWh na loadin bateri na yauwa kuma bukata wani rana na autonomy. Aljebra ta amfani da 90% na DoD wanda aka yi amfani da shi kuma ta saba suna 90% na efficiency na system.

Kapastin na nominal = 8 × 1 ÷ (0.90 × 0.90) = 9.88kWh

Wannan aljebra ya nuna kapastin na nominal a matsayin 10kWh kafin mu adda wani margin na project. A cikin akwai wani final selection wanda ya kamata mu duba inverter surge demand, PV recharge window, temperature, battery aging allowance, reserve SOC, da sukunin na module wanda ke da compatibility.

Kapastin na nominal = 5 × 2 ÷ (0.90 × 0.90) = 12.35kWh

Wannan aljebra ba ta nuna automatic na kapastin na 12.35kWh ita ce wani final specification. Ta nuna wasu tambayoyi na gaba: Ya zama iya array ya recharge wannan bank bayan biyu ranan na cloudy? Ya zama inverter ya hanza pump surge? Ya zama generator wani part na operating shin? Wani ne a musu kafin rana? Kuma yanzu ya zama daidai domin wadanda suka biyo waɗannan tambayoyi.
