About Photovoltaic Energy StorageFigure 5 – Phase shift Phase shift is represented as an angle (Ф) and current may be in advance or delayed of voltage. If capacitance of the circuit prevails current is advanced; if inductance prevails current is delayed. This phase shift provokes that "useful power" (active power – unit: W or kW) is lower than the power supplied (apparent power – unit: VA or …

About Photovoltaic Energy StorageA capacitor bank is a group of several capacitors connected in the series or parallel combinations. Capacitors are electrical and electronic components that store electrical energy. Thus, capacitor banks (cap bank) stores the reactive energy (leading) and it compensate for reactive energy (lagging), and improves the power factor.
