Standing behind the semi-transparent noise barrier, Harold watches traffic passing by on the A50. A long string of cars and vans driving along the Sint Oedenrode – Paalgraven section create a soft buzzing sound. Coming up to Moleneind in Uden, they pass a five-metre-high and four-hundred-metre-long noise barrier comprised of 136 integrated solar panels.
The sleek, futuristic, eye-catching barrier is a modular structure that is made up of frames, each containing two interconnected glass plates. Each glass plate contains a large number of double-sided solar cells. The noise barrier limits noise pollution while at the same time both sides of the barrier generate green energy with a capacity of 238 kWp. This makes the noise barrier perfect for Solar Highways an innovative and sustainable initiative of, Heijmans’ client, the Dutch Department of Public Works and Water Management and its partners ECN part of TNO and SEAC (Solar Energy Application Centre).
Solar Noise Barriers
“Heijmans designed and built the noise barrier of solar panels specifically for Solar Highways”, project manager Harold Gommans proudly tells us walking passed it. “Doing so, we worked and continue to work closely with our colleagues at Soil specialisms and the department of System Integration and Technique and the companies Scheuten Glas, Van Campen-Bayards and Libra Energy. We already started the development of a modular solar noise barrier in 2014. This resulted in the SONOB-system (Solar Noise Barriers).
