conversion of sunlight into electricity,
either directly using photovoltaics (PV), (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.)
or indirectly using concentrated solar power (CSP).(boil water which is then used to provide power. )
Other technologies also exist, such as Stirling engine dishes which use a Stirling cycle engine to power a generator.
