How long can solar energy be stored? Theoretically, solar energy stored mechanically can last as long as potential energy is maintained. There''s always energy lost in any energy transfer, and in the case of mechanical storage, leaks always occur during storage and release. The same applies to batteries.

About Photovoltaic Energy StorageCapacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.
About Photovoltaic Energy StorageThe demand side can also store electricity from the grid, for example charging a battery electric vehicle stores energy for a vehicle and storage heaters, district heating storage or ice storage provide thermal storage for buildings. [5] At present this storage serves only to shift consumption to the off-peak time of day, no electricity is returned to the grid.
