Solar energy is one of the most environmentally friendly and long-lasting forms of energy! The technology behind it is awesome. A solar system, also called a photovoltaic system, PV system, solar module or solar panel, consists of individual solar cells that convert sunlight directly into electrical current. This generated energy can then easily be used on the go. Either devices such as cell phones, tablets or cameras can be charged directly from the solar system, or an energy storage device - i.e. an external power bank or battery pack.
