Study finds residential heat pumps offer flexibility potential even during coldest periods An international research team found that residential air-to-water heat pumps retain significant operational flexibility even during extreme winter conditions, as they rarely operate at their maximum capacity. The study of 761 systems in southern Germany shows that intelligent control and thermal storage strategies could enable grid-friendly load shifting while reducing peak electricity demand.

TÜV NORD study finds back-contact advantage over TOPCon is limited to mild shading conditions A TÜV NORD study found that back-contact (BC) modules outperform TOPCon modules under mild partial shading, particularly when three or fewer cells are shaded across different substrings within a string. However, once shading exceeds four cells, the performance advantage disappears, with both technologies experiencing similar power losses of around 50%.
