Characteristics and uses of solar and wind energy

Characteristics of wind and solar energy The use and development of wind energy and solar energy has a history of more than 3,000 years. It is an ancient and young science, a practical science closely related to life, a renewable science that can protect the environment, a science that can develop sustainably now, and an industry that can benefit from just one investment for many years. In many new energy areas, priority is given to the development and use of wind and solar energy. This is a hot topic in the world today because the use of wind and solar energy is a technology that does not require mining, transportation, waste emissions and pollution of the environment. It is an important way to protect the earth and benefit future generations. Complementary power generation technologywind-solar wind-solar complementary power generation technology is a new technology that combines small and medium-sized wind power generation technology with solar photovoltaic technology and integrates various application fields. It involves many fields, has a wide range of applications, and has great technological differentiation, incomparable with various independent technologies. At present, wind power and solar power are the most mature, largest and most industrialized industries in the field of new energy utilization in the world. Wind power and solar power have their own development disadvantages, but wind power and solar power are complementary. The combination of two new energy sources can achieve the most reasonable comprehensive utilization of the new energy in terms ofallocation of natural resources, integration of technical solutions, comparison of performance and prices, etc., which not only reduces the unit cost to meet the same demand, but also expands the scope of the market . In short, wind and solar complementation refers to the combination of wind power generation and photovoltaic power generation to form a power generation system. According to new energy researchers and investors, photovoltaic power generation systems that use solar cells to convert solar energy into electrical energy are clean, but their costs are relatively high and are greatly affected by hours of sunshine, although wind systems are weak; system costs, their operation is The maintenance cost is low, but the quality and reliability are relatively gooddiocres. The combination of the two can complement each other and fully play out their strengths. However, wind and solar hybrid power generation technology is not a simple sum of wind and solar power, but also involves a series of complex technologies and suitable system designs.
