The document discusses solar cells and includes the following key points: 1) A solar cell is a device that generates electricity directly from visible light by connecting a number of cells together to form a solar panel. 2) There are two main types of solar power systems - grid-connected systems where surplus power is sold back to the electricity company, and stand-alone systems where lead-acid batteries are usually used to store energy. 3) The document outlines how solar cells work and can be made at home, but provides no details on the production of products from solar cells.

9. Can the power be stored? The amount of power generated by solar cells is determined by the amount of light falling on them. In a Grid-connected system, the solar array is connected to the mains. Any surplus power is sold to the electricity company, and power is bought back from them when it is needed. In a Stand-alone system, however, this is not possible. In this type of system the usual choice for energy storage is the lead-acid battery. The number and type of batteries is dependent on the amount of energy storage needed.
