Testing Equipment

TESTING & QUALITY

The solar simulator, electroluminescence and hi-Pot testers are the main machines used to test photovoltaic modules. These machines can be positioned at the end of the production line and along the production chain to keep the quality and efficiency of the photovoltaic modules under control after the most sensitive production phases. Each machine uses the best technologies in order to guarantee the best and most accurate measurements.
