Applications of Solar energy
Issue Time:2017-06-06
Solar power is the conversion of sunlight into electricity. Sunlight can be converted directly into electricity using photovoltaics (PV), or indirectly with concentrated solar power (CSP), which normally focuses the sun's energy to boil water which is then used to provide power, and other technologies, such as the Stirling engine dishes which use a Stirling cycle engine to power a generator. Photovoltaics were initially used to power small and medium-sized applications, from the calculator powered by a single solar cell to off-grid homes powered by a photovoltaic array.

A significant problem with solar power is installation cost. Developing countries in particular may not have the funds to build solar power plants, although small solar applications are now replacing other sources in the developing world.
