Turning Light into Power
The SAPC Readypower Battery is a typical back-up system, which stores surplus solar electricity during the day and makes the energy available again when required – for example at night.
The most important component in a photovoltaic array is the solar cell, where light is converted into electricity. About ten to 100 cells form a module. Depending on the electrical output required, several modules are coupled together into a solar generator. In this way arrays with capacities ranging from a few milliwatts to several megawatts can be set up. The costs incurred can be divided half and half between the photomodule and the coupling into an integrated system.
