Feasibility study and study on the combination of photovoltaic power station construction and desert

  • Author:David

I was fortunate to have contacted the construction of several photovoltaic power plants in Inner Mongolia and Gansu. During the period, a phenomenon worthy of attention was discovered. The photovoltaic power station originally built in the desert area has grown lush grass under the solar panels. And according to industry insiders, this phenomenon is not uncommon in many photovoltaic power plants.

  It is understood that the cause can be roughly attributed to the fact that the photovoltaic panel shields the direct sunlight to effectively reduce the evaporation of surface water; and the photovoltaic module board can also effectively reduce the wind speed. It is precisely because of the above reasons that many surface vegetation including forage grass can grow; and the appearance of surface vegetation in turn contributes to the sand fixation and water retention on the surface. It can be seen that the new ecological environment due to the blocking of direct sunlight from the photovoltaic module board has a positive effect on desertification control.

  In the northwestern region of China, land desertification (the main cause of “dust storms”) caused by the transitional agricultural and livestock production is seriously threatening our living environment. The series of small changes that have taken place under the PV module board may provide us with a way to effectively combat desertification. This allows us to have zero emissions and access to energy in the dust (the main cause of "smog"), sulfur dioxide (the main cause of "acid rain") and carbon dioxide (the main cause of "global warming") The land will be reconstructed to retain water and restore green.

For this we recommend:

(1) Carry out research on the role of photovoltaic power stations in controlling desertification as soon as possible.

We noticed environmental changes under the PV module board. But this is not enough. We hope to further carry out research work and seek to further accelerate, enlarge and consolidate this approach to environmental change.

For example, is it possible to modify the design of the component panels or brackets without changing the cost of power generation, so that it has a superior performance in reducing wind speed or reducing surface water evaporation; whether it can be used in the construction of photovoltaic power plants. Vegetation seeds that are drought-resistant and sand-proof are selectively sown to accelerate vegetation growth.

(2) The construction of photovoltaic power stations is one of the means of comprehensive desertification control.

In view of the outstanding performance of photovoltaic power plants in reducing wind speed and reducing surface water evaporation, it is recommended to consider the requirements for environmental management in the site selection construction of photovoltaic power plant construction and operation and maintenance after commissioning.

For example, whether it is possible to consider building a large-scale photovoltaic power plant on the edge of the desert; after obtaining the results of the treatment, the power station will move forward, and the original site of the power station will be used for further soil and vegetation reconstruction; whether it can be, such as drip irrigation, other desert treatment technologies Combined with the construction and maintenance of photovoltaic power plants themselves (such as component cleaning).
