Each panel integrates a full-size, high-efficiency 590 Wp solar module into a structure designed to preserve acoustic performance &#8211; colour matched to the existing street furniture, and of a slightly raised height to show off the innovation. In total, 8 panels deliver a 4.72 kWp system.<\/p>\n<p>The panels are mounted vertically as part of the barrier structure not at the typical 30\u00b0\u201345\u00b0 tilt. While vertical mounting reduces peak output, it offers some advantages:<\/p>\n<ul>\n<li>Better generation during mornings, evenings, and winter months<\/li>\n<li>Improved self-cleaning due to rain runoff<\/li>\n<li>Lower maintenance requirements<\/li>\n<\/ul>\n<p>Expected annual yield is approximately 4 MWh, with real-world best-daily production reaching around 20 kWh.
