Supports various solar cell module tests

The solar cells used for solar power generation, which is the major player among clean energy supply sources, are exposed to a variety of different environment since they are installed outdoors. Therefore, many different types of tests are conducted for their reliability evaluation. Service life evaluation of panel modules is particularly important, and various checks ranging from analysis of causes of failure to standard tests are conducted from the development stage continuing even after the start of product supply. ESPEC satisfies these requirements with the temperature and humidity chambers with larger capacity.

The test area dimensions of the FM Chamber can accommodate changes in units of 50 mm according to the module size and number inserted.

The chamber support various IEC standard tests.

It can also be used as a temperature and humidity chamber for PID evaluation by adding insulation measures and high-voltage static charge prevention measures.

Features

• Achieves a temperature accuracy of ±2°C and a humidity accuracy of ±5% RH on the module surface.*
• High capacity: 3,600 L, 1200 (W) × 1500 (H) × 2000 (D) mm
• Jig for easy handling of large modules (optional)
• Supports insulation measures and high-voltage static charge prevention measures. (Optional)
• Walk-in type design: take-in and take-out of large panel modules is easier.

* When carrying 10 modules with a size of 1300 (W) × 1800 (H) × 50 (D) mm (200 kg)

* Temperature of 1 point on the module surface closest to the center of the chamber (humidity near air temperature)

* With stable temperature and humidity
