The working principle of wind-solar hybridization is mainly based on wind turbines and solar panels. Wind turbines capture wind energy to drive the generator to rotate, thereby generating electrical energy; while solar panels generate photoelectricity by absorbing photons in sunlight to generate electrical energy. The electric energy generated by these two power generation methods can be stored through energy storage equipment (such as batteries), and converted into AC power through an inverter for use by users when needed.

The application fields of wind and solar hybrid are very wide. In remote areas where power grid coverage is difficult, wind and solar hybrid systems can serve as independent power supply systems to provide stable power to local residents. In addition, in public facilities such as urban street lights and traffic lights, wind and solar hybrid systems can also be used as backup power sources or main power sources to ensure that these facilities can still operate normally when the power grid fails. At the same time, wind and solar hybrid systems also have broad application prospects in fields such as agriculture, oceans, and environmental monitoring.

The advantages of complementary wind and solar energy are mainly reflected in the following aspects:

Renewable: Wind energy and solar energy are both inexhaustible and renewable energy sources. Their use can reduce dependence on fossil fuels and reduce environmental pollution.

High stability: Due to the complementary nature of wind energy and solar energy, wind and solar hybrid systems can provide relatively stable power output under various weather conditions and reduce power fluctuations caused by weather changes.

Economics: Although the initial investment of the wind-solar hybrid system may be higher, considering its low long-term operating costs (no need to purchase fuel, low maintenance costs, etc.), and the fact that it can save the cost of power grid construction in some areas, in the long run Seems to have better economics.

In sustainable development, wind and solar hybrid technology play an important role. First, it helps reduce greenhouse gas emissions and environmental pollution, thereby mitigating the effects of global climate change. Secondly, by utilizing local renewable energy resources, wind and solar hybrid technology can promote regional economic development and improve the energy structure. Finally, the promotion and application of wind and solar hybrid technology can also improve the security and reliability of energy supply and reduce the risk of dependence on external energy supply.

In general, wind-solar hybridization is an efficient, environmentally friendly, and economical way of utilizing energy, which is of great significance for promoting sustainable development. With the advancement of technology and reduction of costs, it is believed that wind and solar complementary technology will be widely used in more fields in the future.
