Vertical solar fences and shaded pergolas power a German public pool

In Oberursel, Germany, the TaunaBad public pool added two solar systems: 64 upright bifacial panels on the fence by the parking lot (about 38,000 kWh/year) and three pergolas with 180 panels over the kids’ lawn (about 69,500 kWh/year). Combined forecast is roughly 107,000 kWh/year, most of which is used on-site to run pumps and equipment, avoiding about 30 metric tons of CO2 annually. The fence panels harvest reflected light from the lot, while the pergolas shade the lawn and supply power, with Hessen’s climate program funding a portion; the outdoor pool season drew about 95,000 visitors.

Arctic rooftop goes vertical: 6,400 ballast-free solar panels beat the snow

A Tromsø cold store installed 6,400 vertical, upright solar panels on its flat roof, held only by friction with the membrane and with no ballast or penetrations. The east-west oriented, bifacial units shed snow and gain from reflected light on the white roof, improving yield in high-latitude winter conditions. The system—assembled in 1,600 prebuilt units by Over Easy—was installed in four days and has demonstrated a higher specific yield (about 747 kWh/kWp in Tromsø, versus ~485 kWh/kWp for conventional tilted rooftop arrays, though figures vary by site). If scalable, this ballast-free vertical approach could broaden rooftop solar viability in snowy climates, including parts of North America, though performance depends on location and roof albedo.
