High bifacial factor The HJT technology is the most efficient in using reflected sunlight from the surface underneath, which can significantly increase the power output. Low chance at micro-cracks HJT cells are thinner and therefore more flexible and less susceptible to micro-cracks. Low temperature coefficient With a low temperature coefficient this panel loses just a low percentage of efficiency when the cell temperature rises above 25°C. High performances under low light Thanks to an added thin layer of amorphous silicon, HJT cells only needs a little bit of sunlight to start producing electricity. This makes them ideal for cloudy climates. Ultra Black The Black cells, Black frame, Black spacings and matt finish make this panel a true aesthetic enhancement for your roof. Only the darkest cells are selected to use in our panels. Glass-Glass Glass at the front and at the rear for a longer longevity, lower degradation and less chance of micro-cracks. They are also more weather-, water- and fire-resistant and contain no PFAS. Belgian quality Designed and engineered in the heart of Europe using only parts that meet the highest European requirements for quality and safety.
