Photovoltaic Panels Salt Cycle Equipment,Some highly corrosive wet environments such as marine environments will reduce some of the performance of photovoltaic modules (corrosion of metal parts, protective coatings, plastics and other non-metallic materials due to absorption of salt spray, etc.), which will ultimately affect the normal operation and safety of photovoltaic modules run.

Therefore, PV accelerated corrosion testing the determination of a test method for evaluating the salt spray corrosion resistance of photovoltaic modules is of great significance for improving the quality and safety performance of photovoltaic modules.

Parameter

Photovoltaic Panels Salt Cycle Equipment

IEC 61701

PV Corrosion Test Cabinet

● This standard specifies the test procedures used to determine the resistance of different photovoltaic modules to salt spray corrosion containing Cl- (NaCl, MgCl2, etc.) elements.

● Including sampling, testing procedures, pretreatment, initial measurement, salt spray testing procedures, cleaning and recovery, final testing, requirements, test reports, etc.

● The purpose of the IEC 61701 standard is to evaluate the possible failure of photovoltaic modules in a humid environment with a high concentration of dissolved salts (NaCl).

Compound Test Method

Solar pv salt spray test machine

a. Neutral test

Test room: 35℃±2℃ Saturated air barrel: 47℃±2℃

b. Acid test

Test room: 50℃±2℃ saturated air barrel: 63℃±2℃

c. Humidity test

Test room: 40℃±2℃, relative humidity 90%～95%R?H (equipment can meet the set temperature to 60℃, relative humidity to 98%RH)

The heating is a tank-type heating and humidification method of the inner tank, which has a fast temperature rise and a uniform temperature and humidity distribution

The saturated air bucket adopts automatic water replenishment. After about 20 hours of continuous spraying, the water replenishment will start. After 1-2 minutes, the water replenishment will end and the spraying will continue.

d. Drying test

The air blower is used for drying treatment, and the specimens are dried for 24H under the conditions of standard atmospheric temperature (15℃～35℃) and relative humidity not higher than 50%
