Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of photovoltaic, in particular to a photovoltaic module test device and method considering salt pond environment. BACKGROUND

[0002] In recent years, with the rapid development of new energy represented by wind power and photovoltaic power generation, remarkable results have been achieved, and they play an increasingly important role in the energy system. Wind power, photovoltaic and other major new energy have entered a new stage of large-scale, high proportion, marketization and high-quality development. Photovoltaic modules, as the core part of photovoltaic systems, directly affect the power generation efficiency and service life of the entire system.

[0003] Salt light complementary photovoltaic is a photovoltaic power generation technology that lays photovoltaic modules on salt pond areas, allowing photovoltaic power generation to work in coordination with salt production. Sunlight shines on the modules, and photons excite electrons to generate current. Salt ponds use sunlight to evaporate brine to produce salt, achieving one place for two purposes and improving resource utilization efficiency. Therefore, the coordinated optimization of light resources and salt production is crucial.

[0004] When installing photovoltaic modules on salt pond areas, simulation experiments need to be conducted on the installation angle, array spacing, and relative position of the photovoltaic modules and the salt pond to determine the optimal installation angle, array spacing, and relative position, thereby improving resource utilization efficiency. However, due to the lack of devices with such research functions, the installation angle, array spacing, and relative position of the photovoltaic modules and the salt pond cannot be adjusted during simulation testing, which cannot fully ensure the comprehensive utilization of light resources under the premise of constant salt production and quality, and thus cannot optimize the coordination between photovoltaic power generation and salt production.

[0005] In addition, the corrosion problem of photovoltaic modules in salt pond environments is also an important factor affecting power generation efficiency. In the long-term use process, they will be affected by salt pond environmental factors, leading to corrosion. Corrosion not only reduces the aesthetics of the modules, but also may affect their electrical performance, thereby affecting the overall power generation efficiency. However, in the simulation of corrosive environments, the corrosion of photovoltaic modules in salt pond environments cannot be effectively simulated, resulting in a large deviation between the test results and the actual salt pond environment corrosion, and unable to provide accurate data support for the corrosion resistance design of photovoltaic modules.
