Description

Technical Field

[0002] In current agricultural-photovoltaic complementary projects, in order to maximize land use efficiency and ensure a double harvest of energy and agriculture, orderly and large-scale crop planting is usually carried out under the photovoltaic array. However, such a layout encounters the following problems during rainfall: due to the gaps between the photovoltaic panel arrays, rainwater will penetrate through these gaps or directly drip onto the crops below along the inclined surface of the photovoltaic panels. This non-uniform and uncontrollable rainwater penetration disrupts the precise control of the conventional irrigation system, which may cause the crops to suffer from excessive moisture or local waterlogging, and is not conducive to the root environment of the crops; if the crops are fertilized with nutrient solution, the infiltrated rainwater will mix with it, changing the concentration of the originally formulated nutrient solution, which may result in an inability to meet the specific nutrient element ratio required for crop growth, affecting its physiological processes and yield performance. In addition, frequent rainwater penetration may also lead to the loss of nutrients, increasing the difficulty and input of fertilizer management. Therefore, a water collection structure for photovoltaic panels is proposed to solve the above problems. Summary of the Utility Model
