Both are not profitable. The efficiency of solar photoelectric conversion is 17% in China. Wind power generation is unstable and wind turbines are easy to break if you go to a street with wind lamps. a glance. With the same wind strength, how many rotate, how many rotate offline, and how many don't rotate.
Characteristics of wind energy 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 fields, priority is given to the development and use of wind and solar energy.D. 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. Wind-solar complementary power generation technology 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 fields of 'application. 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 inin the field of the use of new energies 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 new energy in terms of natural resource allocation, technical solution integration, performance and price comparison, etc. ., which not only reduces the unit cost to meet the same demand, but also expands the market scope. 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 researchers and investors in the field of new energies, photovoltaic energy production systems thatuse solar cells to convert solar energy into electrical energy are clean, but their costs are relatively high and are strongly affected by sunlight hours, although wind systems are weak; system costs, their operation is The maintenance cost is low, but the quality and reliability are relatively poor. 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 power and solar power, but also involves a series of complex technologies and suitable system designs.
