The back process pertains to the electrical circuitry, which transmits this electricity. In essence, the panels convert sunlight into direct current (DC) electricity; this is then transformed into alternating current (AC) for household use through an inverter. Sunlight is composed of photons, or particles of solar energy. [1] It is a type of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or. . Solar energy is converted into electricity through the photovoltaic effect, a process where sunlight, composed of photons, agitates electrons in a semiconductor material (like silicon) within solar panels.
