Computer Controlled Photovoltaic Solar Energy Unit
The Computer Controlled Photovoltaic Solar Energy Unit, "EESFC", includes equipment that uses the photo-conversion law, which directly converts solar radiation into electricity. The absorbed energy is provided by simulated solar radiation, which in our case is supplied by a panel with powerful light sources (solar lamps).
Energy Storage
When available energy exceeds the load on the process, a storage subsystem can be added to store the excess solar collector output and return it when needed. The major characteristics of a thermal energy storage system include its capacity per unit volume and the temperature range over which it operates.

Introduction to Photovoltaic Solar Energy | SpringerLink
The larger the increase in photon frequency is its power and similarly, when a photon''s wavelength is longer, its energy is lower. The unit of a kind of photon energy may be the same as that of energy. The most widely used units to indicate photon energy is the electron volt (eV) and the joule or microjoule.
