“Storage” refers to technologies that can capture electricity, store it as another form of energy (chemical, thermal, mechanical), and then release it for use when it is needed. Lithium-ion batteriesare one such te.
[pdf] Its working principle is that when the photovoltaic components generate excess power during the day, the surplus electrical energy is converted into chemical energy and stored in the internal battery pack; and when night falls or encounters rainy weather, the photovoltaic system generates insufficient power, and then the stored electrical energy is released to provide a stable power supply for the load.
[pdf] These units, commonly lithium-ion batteries, can set back consumers by a considerable margin ranging from ZAR 50,000 to ZAR 200,000 on average for a typical installation. This price variability often hinges upon the capacity and brand of the battery system chosen.
