About Photovoltaic Energy StorageThe relationship between current, voltage, and capacitance is I = CdV/dt. This indicates that the current (I) in a capacitor is proportional to the rate of change of voltage (dV/dt) across the capacitor. If the voltage is going up, current must be flowing into the capacitor. If the voltage is going down current must be flowing out of the capacitor.
