External environment testing device of photovoltaic module

Abstract

The invention discloses an external environment testing device of a photovoltaic module capable of simulating wind, rain, snow and hail. In order to verify the product quality, an enterprise simulates various environment climates by using an environment testing device in the prior art. For a product exposed to an outdoor environment, simulation of the influences of wind, rain, snow and hail on the product is particularly important. According to the external environment testing device, a spray system, a snow simulation system, a hail simulation system and a wind simulation system are arranged on an experiment platform device. A thin-film pressure sensor covers on a photovoltaic module, the pressure of various systems is adjustable and nozzles of all simulation systems have mechanical degree of freedoms, so that the climate conditions under more complicated and changeable circumstances can be simulated. Data of the thin-film pressure sensor on the photovoltaic module are fed back to the control system in real time, so that output pressure of the systems is adjusted according to the experiment requirements. By adopting the design, experiment simulation can be further carried out close to life, accurate experiment data can be known and the testing process can be controlled.

Description

technical field [0001] The invention relates to a photovoltaic module external environment test device, in particular to a photovoltaic module external environment test device capable of simulating wind, rain, snow and hail. Background technique [0002] Enterprises have a way to verify product quality, using environmental test equipment to simulate various environmental climates, so as to verify whether the product meets the expected quality goals in R&D, design, and manufacturing. Because photovoltaic modules are mostly used in the field of outdoor solar power, the climate environment is an important factor affecting the use of photovoltaic modules, and the impact of wind, rain, snow, and hail is particularly prominent.

Problems solved by technology

[0004] However, even if this kind of simulated transportation vibration table is used, in the simulation test of the external environment of photovoltaic modules, the strength and direction of wind, rain, snow and hail in the actual natural environment are changeable, and it is difficult to be more similarly simulated in the existing technology, and The measurement and control system generally has a limited role, and the experimental results of photovoltaic modules are generally concluded after the experiment. It is difficult to monitor the local force status of the photovoltaic module during the experiment in real time, and it is difficult to control the parameters of the test in real time through the data of the test piece.
