Solar battery

The solar energy can be used not only in big plants but also for small applications. In this picture we can see a portable solar battery, made up of a cover with the photovoltaic cells for the production of energy that is accumulated in the battery contained in the blue box. This portable solar battery has been developed to be presented at the exhibition of the appliances for the production of solar energy in Willets, California (United States). Willets is known as the world capital of the solar energy systems. (picture copyright CORBIS)
