Solar panel. Solar panels absorb the sunlight as a source of energy to generate electricity or heat. A photovoltaic (PV) module is a packaged, connect assembly of typically 6x10 photovoltaic solar cells.
Currently, the use of solar energy to create electricity, thru what is called photovoltaic cells and coatings, is the dominant field in developing the potential of solar energy. Engineering and development is focused on improving the efficiency of solar panels that create the energy, by increasing the amount of energy, in watts, that is created, per square foot of panel. The development of better and more efficient means of storing this electrical energy, in the form of batteries, is a major engineering focus.
