Solar power in Israel – with no oil reserves and the country's tenuous relations with its oil-rich neighbors, the search for a stable source of energy is a national priority. [1] [2] Solar technology in Israel has advanced to the point where it is almost cost-competitive with fossil fuels. [3]
Solar energy is the radiant energy from the Sun's light and heat, which can be harnessed using a range of technologies such as solar electricity, solar thermal energy (including solar water heating) and solar architecture.
Solar Towers from left: PS10, PS20. The first three units of Solnova. I (right) III (left, front) and IV (left rear). The two towers in the background are the PS10 and PS20 solar power stations. PS10 is the first of a set of solar power generation plants to be constructed in the same area that will total more than 300 MW by 2013.
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current . [ 2 ]
One of the first applications of concentrated solar was the 6 horsepower (4.5 kW) solar powered motor made by H.E. Willsie and John Boyle in 1904. [ 112 ] An early solar pioneer of the 19th and 20th century, Frank Shuman , built a demonstration plant that used solar power to pump water using an array of mirrors in a trough to generate steam.

Usually solar panels are exposed to sunlight for longer than this in a given day, but the solar irradiance is less than 1000 W/m 2 for most of the day. A solar panel can produce more when the Sun is high in Earth's sky and produces less in cloudy conditions, or when the Sun is low in the sky. The Sun is lower in the sky in the winter.
A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...
