The development prospect of solar energy utilization in various countries in the world is different.

China

China is rich in solar energy resources and has a bright future. At present, the scale of China's solar energy industry ranks first in the world. It is the country with the largest production and use of solar water heaters and an important producer of solar photovoltaic cells. There are two mature solar energy products in China: solar photovoltaic power generation system and solar hot water system.

Australia

Solar researchers at the University of New South Wales (UNSW) in Australia have been able to convert solar energy into electricity more than 40%, the highest ever.

U.S.A

There are many projects in the United States and other countries that use solar ponds to generate electricity. On the Bank of the dead sea is a 7000 square meter experimental solar pond built in 1979 to heat a 150 kW generator. The United States plans to build 8.3 percent of its salt lake area (about 8000 square kilometers) into a solar pond to heat 600 megawatt generating units.

Armenian

Experts from the Institute of radio physics announced that the construction of its "first small experimental prototype" industrial solar power plant has been started in the mountainous areas of the country. The turbine used in the power station is a turbine which has been removed from the helicopter after its service life has expired. The installed capacity is only 100 kW, but the cost of power generation is only 0.5 cents / kWh, and the efficiency is as high as 40% - 50%.

Russia

Russian scholars have also made remarkable progress in solar pond research. A company designed a new type of solar pond suitable for farmers by combining its solar water jet thruster and jet cooling propeller with solar pond project and installing ice trough and other facilities for the solar pond. According to this design, a household of 6 to 8 people can build a 70 square meter solar pond, which can meet the annual electricity demand of its 100 square meter house.

Israel

Solar energy in Israel has been the most widely used. In 2012, the installed capacity of renewable energy is 6.2 MW for wind energy, 8 MW for hydropower, 12 MW for biofuel, 7 MW for medium-sized solar photovoltaic power station, and 218 MW for small-scale photovoltaic power station. At present, large-scale solar photovoltaic thermal power plants will increase to 740 MW, medium-sized solar power stations will increase to 330 MW, and small-scale photovoltaic power stations will increase to 330 MW.

Solar panels have their service life, and then become waste, waste treatment is difficult. Although solar energy is a clean energy, whether the products related to solar energy will cause secondary pollution is still a topic to be seriously studied.
