The disadvantages of these two power generation systems are:
1 Relatively low energy density: The disadvantages of wind and solar power generation are that they have low energy consumption. density and require large amounts of energy. Only a zone of zone can get enough energy. Wind and solar energy production requires more land resources.
2. Limited by natural conditions: Disadvantages of wind and solar power generation include that wind and solar power generation is affected by factors such as weather, season, geographic location, etc., and the continuity. and stable power supply cannot be guaranteed.
3. Energy storage technology is not yet mature: Disadvantages of wind and solar power generation include the fact that the technologie energy storage is not yet mature and it is difficult to solve the problem of unstable energy production before. The breakthrough of energy storage technology, wind power and the proportion of solar power generation in the grid is limited.
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 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 useOne of wind and solar energy is a technology that does not require mining, transportation, waste emissions and environmental pollution. 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 in the field of new energy utilization in the world. EnergyWind 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 new energy researchers and investors, photovoltaic power generation systems that use solar cells to convert solar energy into energye electric are clean, but their costs are relatively high and are strongly affected by the 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 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 and solar power, but also involves a series of complex technologies and suitable system designs.
