Solar power is produced by collecting sunlight (solar radiation) and converting it into electricity (usable energy). The level of solar radiation a region receives is relative to latitude and local weather conditions. This is done by using solar panels, which are large flat panels made up of many individual solar cells. It is more commonly used in remote locations, although it is becoming more popular in urban areas as well. The design of building and windows in such a way that they carefully balance their energy requirements without additional mechanical equipment, is very important for tapping passive solar energy and can save substantially on electricity bills. Solar energy can be utilized in various ways, including to provide electricity, mechanical power, heat and lighting.
