Solar Power

Every life of solar power generation depends on solar energy. Solar energy is the energy source of photosynthesis. It provides the plants and animals the warmth they need to survive. The heat from the sun evaporates the water on the surface of the earth, forming clouds and ultimately bringing fresh rain. Solar energy is the result of thermonuclear fusion reactions under deep sun. The energy produced by these reactions is so large that they maintain the surface temperature of the sun at about 10, 300 ° F.

Solar energy is the conversion of solar energy to electric energy, direct use of photovoltaic (PV), indirect use of centralized solar energy, or a combination. The centralized solar system uses a lens or mirror and a tracking system to focus a large area of ​​sunlight into a small beam. Photovoltaic cells use a photovoltaic effect to convert light into electricity. Photovoltaic power was used only as a power source for small and medium-sized applications, from a calculator that originally operated with a single solar cell to a remote home that operates on an off-grid rooftop PV system. Commercial concentrating photovoltaic power plant was first developed in the 1980's. Ivanpah's 392 MW facility is the world's largest concentrating solar power plant in the Mojave Desert, California.

Solar power generation is expected to become the world's largest power supply source by 2050, solar power generation and concentrating solar power generation each account for 16% and 11% of world consumption. After one year of rapid growth, in 2016, 1.3% of the world's electricity was generated by solar energy. Commercial concentrating photovoltaic power plant was first developed in the 1980's. The 392 MW Ivana Solar Power Plant in the Mojave Desert in California is the world's largest photovoltaic power plant. Other large centralized solar power plants include Spain's 150 MW Solnova solar power plant and 100 MW Andasol solar power plant. The US 250 MW Agua Caliente Solar Project and India's 221 MW Chalanka Solar Park are the world's largest photovoltaic power plants.

Commercial light concentrating solar (CSP) plant also known as "solar thermal power plant" was originally developed in the 1980's. The 377 MW Ivana solar power generation facility in the Mojave Desert, California is the world's largest solar thermal power plant project. Other large scale CSP power plants include Solnova solar power plant in Spain (150 MW), Andasol solar power plant (150 MW), and Extresol solar power plant (150 MW). The main advantage of CSP is that you can add power efficiently and supply power within 24 hours. Since peak power demand usually occurs around 5 pm, many CSP power plants use 3 to 5 hours of thermal storage.
