Ullevaal Stadium in Oslo features the world's largest vertical solar panel installation, consisting of 1,242 bifacial solar panels. These panels are designed to generate at least 250,000 kWh of electricity annually, making them efficient in colder climates. Unlike traditional panels, vertical panels can yield up to 20% more energy and require less maintenance. The technology is part of a broader trend towards integrating renewable energy solutions in public venues, contributing to sustainability efforts across Europe. Teljes cikk (Euronews.com)
