The World’s First PV System in Rainbow Colors

Hamburg, Germany

Overview

YEAR OF INSTALLATION: 2025
PROJECT SITE: Millerntor-Stadion Hamburg St. Pauli
ROOF TYPE: Trapezoidal metal sheet
SYSTEM: K2 MultiRail with K2 SingleRail
NUMBER OF MODULES: 1080
TOTAL CAPACITY: 316 kWp
PLANT OWNER: LichtBlick
POWER GENERATION: The system, covering approximately 1,800 square meters, generates around 285,000 kilowatt-hours of solar power annually—enough to supply about 80 multi-family households. This results in CO₂ savings of 135 to 140 metric tons per year.

Project Highlight: Colorful PV Modules

Thanks to Fraunhofer ISE’s innovative color technology—MorphoColor®—the colored modules achieve up to 94% of the performance of conventional black modules. Instead of using color pigments, a so-called photonic structure is applied. This special surface technology selectively reflects a narrow range of the light spectrum, while most of the sunlight continues to be efficiently utilized for power generation. (Source: LichtBlick)

The K2 Solution: Color-Matched Module Clamps

Special projects call for special solutions: To visually match the rainbow-colored PV modules, K2 laminate module clamps were specially coated with a scratch-resistant, color-stable ceramic finish.
