Solar energy is generated by converting sunlight into usable electricity through the use of solar panels. These panels are made up of photovoltaic (PV) cells, which capture and convert the sun''s rays into a direct current (DC) electrical flow. This flow is then converted into alternating current (AC) electricity, which can be used to power
When photons strike a PV cell, they will reflect off the cell, pass through the cell, or be absorbed by the semiconductor material. Only the photons that are absorbed provide energy to generate electricity. When the semiconductor material absorbs enough sunlight (solar energy), electrons are dislodged from the material''s atoms.
The Importance of Solar Energy. Solar energy is not only a clean and renewable source of power but also offers numerous benefits.

The initial step in the process of solar energy conversion involves the absorption of sunlight by the photovoltaic (PV) cells within a solar panel. These cells, constructed from semiconductor materials such as silicon, capture photons from sunlight. When these photons strike the PV cells, they excite electrons, thereby creating an electric current.
