A solar array is any order or group of solar panels and is used for energy production or water heating. A solar array can be as big as we need it to be and deliver enough energy or warm water for an entire house. An important aspect is the array placement.
A solar panel collects light energy from the sun and turns it into electricity. Roof mounting is a common form of positioning solar panels. By mounting on the roof, you put the photovoltaic cells in a location that gives them a full dose of sunshine.
Most people have heard of solar panels, but not everyone understands how solar panels work. Solar panels work to harness the sun's energy and to convert light into electric current through a process called the photovoltaic effect.
