Embodiment 1

[0032] Such as figure 1 A uniform light photovoltaic agricultural system is shown, which includes a support 1 and a solar photovoltaic panel assembly 2 on the support 1. The solar photovoltaic panel assembly 2 includes a first solar photovoltaic panel 21, a second solar photovoltaic panel 22 and a pressure groove light splitter. The glass plate 23, the grooved light-splitting glass plate 23 realizes the splitting effect on sunlight, the grooved light-splitting glass plate 23 is on the lower side of the second solar photovoltaic panel 22, the first solar photovoltaic panel 21, the second solar photovoltaic panel 22 and The width of the grooved light-splitting glass plate 23 is 1.07m, and there is a 5mm gap between the second solar photovoltaic panel 22 , the first solar photovoltaic plate 21 and the grooved light-splitting glass plate 23 .

[0033] Such as figure 2 As shown, the grooved light-splitting glass plate 23 is made of high transmittance glass 4 , the upper surface 4...

Embodiment 2

[0042] Such as Figure 7 As shown, the difference between the second embodiment and the first embodiment is that: the upper side of the solar photovoltaic panel 21 is also equipped with a grooved light-splitting glass plate 23, and its lower surface is also formed by an array of grooves. The advantage of this installation method is that the uniform irradiation of sunlight 5 on the agricultural land 6 can be realized when the installation height of the solar photovoltaic panel assembly 2 is relatively low.

Abstract

The invention discloses a uniform light type photovoltaic agricultural system. The system can perform photovoltaic power generation under the condition of not influencing the growth of vegetation on an agricultural land, and solves the problem that plants fight for light with a photovoltaic panel. The uniform light type photovoltaic agricultural system comprises a support, a first solar photovoltaic panel, a second solar photovoltaic panel and a pressure groove light splitting glass plate, and the first solar photovoltaic panel, the second solar photovoltaic panel and the pressure groove light splitting glass plate are sequentially installed on the support side by side from top to bottom. And gaps exist between the second solar photovoltaic panel and the pressure groove light splitting glass plate and between the second solar photovoltaic panel and the first solar photovoltaic panel. The upper surface of the pressure groove light splitting glass plate is a plane, the lower surface of the pressure groove light splitting glass plate is provided with a pressure groove array, and the pressure groove array is obtained through segmentation and translation of a specific free-form surface. And light uniformly irradiates projection areas of the first solar photovoltaic panel, the second solar photovoltaic panel and the pressure groove light splitting glass plate along the light irradiation direction.

Description

technical field [0001] The invention relates to the cross-technical field of solar photovoltaic power generation and agriculture, in particular to a uniform light photovoltaic agricultural system. Background technique [0002] The per capita arable land in my country is only 1.38 mu, which is less than 40% of the world average. How to efficiently use the precious cultivated land resources to bring more benefits to people is of great significance to stimulate the development of rural economy. In recent years, with the increase in the power generation efficiency of solar photovoltaic panels, the photovoltaic agricultural system compatible with "farming + power generation" provides us with a new technical route for the efficient use of cultivated land resources. [0003] Throughout the year, the solar altitude angle at any point on the earth is constantly changing. The solar altitude angle is high in summer and low in winter. At present, the main problems in the photovoltaic ...
