Balancing electricity loads – Without storage, electricity must be generated and consumed at the same time, which may mean that grid operators take some generation offline, or “curtail” it, to avoid over-generation and grid reliability issues. Conversely, there may be other times, after sunset or on cloudy days, when there is little solar production but plenty of demand for power.
The photovoltaic processes generate a direct current, so an inverter is needed to convert the DC power to AC power. The electricity is then stored in a battery, where the energy is stored as chemical bonds until it is

We think it is unlikely to be feasible to run larger domestic or industrial appliances with BPVs (Stage 4), whether the power is generated locally or supplied by a grid, because of the large surface area that would be needed for power generation. For the same reason, it is even less likely to be feasible to incorporate BPVs into transport vehicles to power them. The
