Le camere per test di invecchiamento ultravioletto vengono utilizzate nel fotovoltaico (solare fotovoltaico) field to evaluate the durability and weatherability of solar photovoltaic materials and modules under long-term ultraviolet light. It can simulate environmental conditions such as solar radiation, temperature and humidity, and perform accelerated aging tests on photovoltaic materials and modules to evaluate their performance and life prediction in the actual outdoor environment.

Applicazione specifica
The following are some specific aspects of UV aging test chamber in photovoltaic applications:

Evaluation of material weather resistance: photovoltaic materials, come i wafer di silicio, backplane, packaging adhesives, eccetera., will be affected by ultraviolet light, cambiamento di temperatura, humidity and other factors when exposed to outdoor environment for a long time. The UV aging test chamber can simulate these external conditions and evaluate the weatherability and anti-aging properties of materials through accelerated aging tests.

Valutazione delle prestazioni del modulo: Moduli fotovoltaici (photovoltaic panels) are the core part of the photovoltaic system, whose performance and life are crucial to the efficiency and reliability of the system. The stability of photovoltaic conversion efficiency, caratteristiche di temperatura, power attenuation and loss of photovoltaic modules can be evaluated through long-term ultraviolet irradiation and environmental simulation in the ultraviolet aging test chamber.

Material optical performance test: The optical performance of photovoltaic materials is an important factor to determine its energy conversion efficiency. Ultraviolet aging test chamber can be used to test optical characteristics of photovoltaic materials such as transmittance, reflectance and absorptivity, so as to evaluate the optical stability and photoelectric conversion efficiency of materials under ultraviolet radiation.

Assessment of resistance to salt spray: In alcune zone, salt spray in Marine environments can cause corrosion and damage to materials and components of photovoltaic systems. The UV aging test chamber can simulate the salt spray environment and conduct salt spray corrosion tests on photovoltaic materials and modules to assess their salt spray resistance and corrosion resistance.

Heat resistance evaluation: Photovoltaic modules need to be able to work stably at high temperatures. By simulating the high temperature environment in the ultraviolet aging test chamber, the thermal aging test of photovoltaic modules can evaluate the heat resistance, temperature coefficient and heat loss and other performance indicators.

Test procedure
When using UV aging test chamber for photovoltaic tests, è possibile seguire i seguenti passaggi:

preparazione del campione: Prepare samples of photovoltaic materials or photovoltaic modules of a certain number and size, ensuring that they represent the material and design to be tested.

Set the test parameters: according to the requirements and standards of the test, set the parameters of the ultraviolet aging test chamber, including the radiation intensity, temperatura, humidity and test time of the ultraviolet light source. These parameters are adjusted based on specific test criteria and required test results.

Install the samples: Install the PV samples in the test chamber, making sure they are in the proper position and attitude. For photovoltaic modules, install them according to the actual installation method, and ensure that the spacing and layout between samples conform to the actual situation.

Inizia la prova: Start the ultraviolet aging test chamber and let the ultraviolet light source irradiate the sample. Allo stesso tempo, la temperatura e l'umidità nella camera di prova sono controllate per simulare le condizioni ambientali reali. Impostare il tempo di test richiesto in base ai requisiti del test.

Monitoraggio e registrazione: During the test process, the changes of photovoltaic samples are regularly monitored and recorded. This can include the measurement of photoelectric conversion efficiency, the measurement of current-voltage characteristic curves, the observation of appearance, the measurement of heat loss, eccetera. Professional testing equipment and measuring tools can be used for accurate data recording.

Analisi e valutazione: According to the test results, the performance of the photovoltaic sample is analyzed and evaluated. Compare pre – and post-test data to observe trends and performance losses. Secondo lo scopo del test, the weatherability, stability of photoelectric conversion efficiency, salt spray resistance and heat resistance of the sample are judged to meet the requirements.

Rapporto sui risultati: Generate a test report based on the test results, detailing the test process, the methods and parameters used, as well as the analysis and evaluation of the test results. Il rapporto può includere immagini, charts and data tables to visually show the results of the test.

It is important to note that specific testing methods and procedures may vary based on different standards, requisiti, e attrezzature. Perciò, before conducting a test, carefully study the relevant test standards and operation manuals, and perform the operation as required. Inoltre, al fine di garantire l’accuratezza e l’affidabilità dei risultati dei test, selezione ragionevole del campione, Anche l'installazione del campione e il controllo delle condizioni di prova sono molto importanti.
