Problems solved by technology

[0005] Double-sided photovoltaic modules are different from ordinary single-sided photovoltaic modules. The installation height will have a greater impact on the radiation on the back of the double-sided module. Power generation gain, but from an economic point of view, increasing the installation height of the components will lead to an increase in the cost of the bracket, which will increase the initial construction cost of the entire photovoltaic system, thereby affecting the cost of electricity of the entire photovoltaic system

Embodiment 1

[0037] Such as figure 1 As shown, it is a cross-sectional view of different installation heights of the double-sided photovoltaic module array. When the solar elevation angle is consistent with the installation angle of the double-sided module, the size of the shadow surface l projected by the module on the ground due to the sun remains unchanged, that is, l 1 = l 2 . From the two-dimensional cross-sectional view, it is assumed that the reflection on the projected shadow surface is diffuse reflection. According to the principle of radiation angle coefficient, l 1 The emitted reflection will be a, b 1 , c 1 absorbed by the surface, where the radiation received by surface a accounts for l 1 The ratio of total radiation emitted is a / (a+b 1 +c 1 ), that is, the angle coefficient of the back area a of the double-sided photovoltaic module relative to the shaded surface l is a / (a+b 1 +c 1 ). with height h 1 increase, b 2 >b 1 、c 2 >c 1 , a remains unchanged, the angle c...

Abstract

The invention discloses a method for optimizing the installation height of a double-sided photovoltaic module. The method comprises the following steps that firstly, the back side irradiation gain etaof the double-sided photovoltaic module at different heights is calculated; secondly, the back side irradiation gain and the front side and back side irradiation amount are used for determining the total irradiation amount Gtot of the double-sided photovoltaic module; thirdly, according to the total irradiation amount Gtot of the double-sided photovoltaic module, the total power generation amountQ of a photovoltaic system under the installed capacity in the whole life cycle is calculated; fourthly, the corresponding support cost required by installation of the double-sided photovoltaic module under different heights is calculated, the cost per kilowatt hour LCOE is obtained according to the ratio of all investment cost in the life cycle to the calculated total power generation amount Q,and the installation height correspondingly obtained from the lowest cost per kilowatt hour is the optimal installation height. By means of the method, the optimal design of the photovoltaic system inthe whole life cycle under dynamic investment can be calculated, the optimal installation height of the double-sided module can be obtained, and it is guaranteed that the irradiation amount of the double-sided photovoltaic module is given full play of under the condition that the cost per kilowatt hour is low.

Description

technical field [0001] The invention belongs to the technical field of solar energy, and in particular relates to a method for optimizing the installation height of a double-sided photovoltaic module. Background technique [0002] Bifacial photovoltaic modules have attracted widespread attention due to their double-glass structure and the ability to generate electricity on both sides. Bifacial modules have been mass-produced and used in distributed power generation systems such as sound-proof walls, fishing-solar hybrids, and agricultural-solar hybrids. In recent years, double-sided photovoltaic modules have attracted much attention. The literature "Han Jinfeng, Zhao Weiwei, Guo Zhengyang, etc. Factors affecting the power generation on the back of double-glass double-sided power generation modules [J]. Science and Technology and Enterprise, 2015 (22)" obtained components through comparative experiments The east-west vertical installation is better than the standard 30° angle...
