PID Testing Equipment
The potential induced degradation (PID) is addressed with the standard IEC TS 62804-1. The standard defines two methods that enable analyzing occurring PID effects in a specific PV module type. PSE AG offers the necessary equipment for the test in a climate chamber. The test equipment can work with any climate chamber on the market and is delivered turnkey. It comes with all necessary equipment, high voltage power sources, sensors, data acquisition and software.

Outdoor Exposure Tester
OET
A comprehensive analysis of PV modules includes many different parameters. Determining the normal module operating temperature (NMOT), incidence angle effects and comparing soiling effects on different modules up to the initial degradation of PV modules are all parameters that can be analyzed with our outdoor exposure tester. The tester comes with up to twelve electronic loads installed in a 19" rack. The loads have two main functions: maximum power point tracking (MPPT) and IV curve tracing. For the advanced analysis, it is possible to change between these two modes within one test. In the normal operation mode, the electronic load keeps the module under MPP and each predefined interval an IV curve is traced. The entire tester comes with all necessary sensors such as temperature sensor, which can be attached to the module to determine the NMOT temperature like defined in IEC 61215 (MQT 05) and IEC 61853-2. The irradiation sensor is also included. In combination with our tracking system P2, it is also possible to determine incident angle effects of the PV module. It is also possible to connect other irradiation sensors for diffuse and direct irradiation, which helps to understand the behavior of the module in different irradiation conditions. An optional albedo meter is a powerful tool for the analysis of bifacial modules. The entire graphical user interface is web based and offers the possibility to access the system from the all computers in the network.

Hail Impact Tester
HIT
Hailstorms can cause severe damage to modules and collectors. Our test stand enables you to carry out tests according to international standards. The hail impact test stand uses an air-pressurized launcher that shoots ice balls representing hailstones of a predetermined size at the module or collector mounted on the support frame.

Power Supply Rack For Climatic Cycling Test
One essential part of the module quality testing according to IEC 61215 is the thermal cycling test (MQT 11) and humidity freeze test (MQT 12). Besides the environment simulation in the climate chamber, it is necessary to energize the PV modules during specific parts of the test.

System and Collection Tester
SysColl
For certification in many markets, performance of the complete factory made system (for example thermosiphon systems) plays an equally important role as collector performance. Our SysColl test stand is a combined test facility for performance testing of both solar collectors and solar thermal systems. This allows you to take advantage of a flexible two in one test solution.

IV Curve Tracer
IVCT
In recent years, we have been developing a sophisticated IV curve tracer for PV modules including a maximum power point tracking (MPPT) function. The IV curve tracer is designed for operation with any market-available steady-state solar simulator. Through our web-based software design, the operator can supervise the test results from every computer in a company network. The software contains functions such as an irradiation sum counter that helps to check requirements stated in a stabilization test like they are defined in IEC 61215 (MQT 19). We have also included a correction function to correct the traced IV curves to standard test conditions (STC) when the user enters the required temperature coefficients. One of the most important features is the multi-IV curve tracing function, which enables the user to display more than 150 IV curves in one graph. This eases the analysis of the weakest cells in hot-spot tests, which are required in IEC 61730 (MST 22) and IEC 61215 (MQT 09).
