I've been hearing a lot about a new type of solar power. What is it and how can I use it?

Solar power is the conversion of sunlight into electricity. It's made up of two main components - photovoltaic cells, which convert light energy directly into electrical current, and batteries, which store the generated electricity for later use. Photovoltaic cells are usually made from silicon and other materials such as copper and gallium arsenide. The most common type of cell is called a solar panel, which consists of several individual cells connected together in series or parallel.
