Can Solar Power Generation Deal with the Sandstorm?

Can Solar Power Generation Deal with the Sandstorm?


In 2013, there are several solar power generation projects in Inner Mongolia and Gansu. During this period, a phenomenon worthy of attention was discovered. The solar power station originally built in the desert area grew lush pastures under the solar panels. According to industry insiders, this occurs in many solar power stations, which is not common.
 
It is understood that the cause can be attributed to the fact that the solar module panels can effectively reduce the evaporation of surface water due to the direct sunlight shielding, and the solar module panels can also effectively reduce wind speed. It is precise because of the above reasons that many surface vegetation including pastures can grow, and the surface vegetation helps to fix sand and water on the surface. The new ecological environment created due to the blocking of solar module panels from direct sunlight has a positive effect on desertification control.
 
In Northwest China, land desertification caused by excessive agricultural and animal husbandry production is seriously threatening our living environment. This series of small changes under the solar panel may be able to find a way for us to effectively control desertification. This allows us to generate zero emissions of dust (the main cause of smog), sulfur dioxide (the main cause of acid rain), and carbon dioxide (the main cause of global warming) and obtain energy. The land is transformed to fix sand and water.
 
The following advice should be paid attention to:
(1) Conduct research on the role of solar power plants in controlling land desertification as soon as possible.
We noticed a change in the environment under the solar panel, but this is not enough. We hope to carry out further research work to find ways to further accelerate, amplify, and consolidate this environmental change. For example, whether it is possible to modify the design of the module plate or the bracket without changing the cost of power generation, so that it has better performance in reducing wind speed or reducing surface water evaporation; whether it is possible to build a solar power station while selectively sow drought-resistant and sand-resistant vegetation seeds to accelerate vegetation growth.
 
(2) Take the construction of solar power stations as one of the means of comprehensive control of desertification.
In view of the outstanding performance of solar power plants in terms of reducing wind speed and reducing surface water evaporation, it is recommended to consider adding environmental governance requirements for comprehensive consideration in terms of site selection and construction of solar power plants and operation and maintenance after commissioning. For example, whether it is possible to consider building a large area of solar power stations on the edge of the desert; after the treatment results are obtained, the power station will be moved forward, and the original site of the power station will be further transformed into soil and vegetation; whether it is possible to combine other desertification technologies, such as drip irrigation, with the solar power station's construction and maintenance such as component cleaning.
