Implementing energy storage for peak-load shifting

Energy storage can be used to shift the peak generation from the PV system to be used when the demand requires it, as shown in Figure 3. Excess energy can be stored during peak PV generation. This allows for the distribution of this energy when the PV system is not generating adequate power, or not generating at all.
