Solar energy, which is easy and fast, also has the potential to save electricity and is the preferred option for household life. After many years of effort, the use of solar energy in israel is at an advanced level in the world, with per capita ownership of solar water heaters for domestic use at the top of the global list. The weizmann institute and the ben-gurian solar research centre are the two main israeli solar research institutes. In addition, similar studies are available in higher education institutions, such as the institute of sea law technology. The weizmann institute is engaged in high-technology research and development for solar energy, such as new technologies as solar heat, photovoltaic, photochemistry use, the absorption storage and transmission of solar energy, and solar-powered lasers. Ben-gurian centre for solar research is more specialized, and it is in fact a demonstration centre for solar thermal and photovoltaic conversion facilities in israel and a platform for international exchanges of solar energy technology with excellent scientific and technical expertise. There are two basic ways to convert solar energy to electricity, the first of which is to convert solar radiation to thermal energy, namely, "solar heat generation"; the second is the conversion of solar light directly to electrical power, the "solar light generation". Solar light reaching the earth's surface is widespread and dispersed, and to be fully collected and given thermal efficiency, a system capable of concentrating solar light into thermal energy must be adopted. Solar photothermal conversion is the conversion of solar radiation energy to thermal energy for direct use with a collector. Thermal collectors can absorb solar radiation directly, as well as concentrate solar radiation after it is concentrated, heating heat media for domestic heating, hot water supply, industrial heating, agricultural greenhouses, etc. As early as 1955, israeli scientists had developed "selective absorbent coatings", the use of which would significantly increase the heat efficiency of the collectors and would have a high absorption rate of short-wave components, which accounted for more than 90 per cent of solar light energy, marking a solid step in israel's research and use of solar energy. In 1986, the government of israel had introduced a special decree requiring each new building to be equipped with solar water heaters, thus allowing the use of solar energy to reach thousands of households. Currently, more than 80,000 new homes in israel are installed with solar water heaters every year. About 3 per cent of the country's energy supply is provided by widely used solar water heaters. The government has also continued to improve its policy on solar energy use, establishing strict quality standards for the production and installation of solar water heaters and establishing a system of quality monitoring and improvement/enhancement. Indeed, humans have a long history of using solar energy. As early as 2,000 years ago, my country knew about the use of four mirrors to focus on solar light to light fire, how to use solar energy to bake by-products, etc. In recent times, humans have been developing solar energy. However, israel's successful development of solar energy collectors and solar energy devices was remarkable, and the results of those research had led to the development of solar energy industries. Solar energy has won the market with good services, and heating has responded to market demand and has been well received by the affiliated parties. In the near future, israel had developed a new solar energy receiver for concentrated sunlight, which would promote wide-ranging applications of solar energy in industry。
