Solar power in Israel

The use of solar energy began in Israel in the 1950s with the development by Levi Yissar of a solar water heater to address the energy shortages that plagued the new country.^[1] By 1967 around 5% of water of households were solar heated and 50,000 solar heaters had been sold.^[1] With the 1970s oil crisis, Harry Zvi Tabor developed the prototype of the solar water heater now used in over 90% of Israeli homes.^[2] There are over 1.3 million solar water heaters installed as a result of mandatory solar water heating regulations.

Israeli engineers have been at the cutting edge of solar energy technology^[3] and its solar companies work on projects around the world.^[4] However, even though Israeli engineers have been involved in both photovoltaic and concentrated solar power, the earliest Israeli companies which have become market leaders in their respective fields have all been involved in concentrated solar power. Some notable examples of this are BrightSource, Solel and Brenmiller Energy which all deal with utility scale projects. Additionally, Herzliya based SolarEdge has become a market leader in inverters for non-utility scale photovoltaic solar power.

In 2009, Israel found natural gas reserves within their exclusive economic zone which may reduce urgency of solar development. Solar technology in Israel has advanced to the point where it is almost cost-competitive with fossil fuels.^[2] The high annual incidence of sunshine in the Negev Desert has spurred an internationally renowned solar research and development industry.^[5] At the end of 2008, a feed-in tariff scheme was approved which has led to many residential and commercial solar energy power station projects.

Israel's objective in 2011 was to produce 10% of the country's energy from renewable sources by 2020,^[6] and officials from Cabinet and The Electricity Authority gave the goal in 2023 to produce 30% of the country's energy from renewable sources by 2030.^[7][8][9]
