Solar Highways A noise barrier with bifacial PV

Solar Highways A noise barrier with bi-facial PV modules Dirk van der Graaf, Workinggroup Noise Eurocities, Munchen, 14 september 2016

Noise barriers and solar energy • • 2 Many kinds of noise barriers Most of them are just noise barriers Some are multipurpose A very few are producing solar energy RWS UNCLASS Rijkswaterstaat Solar Highways

Solar Highways: a demonstration project • • 3 Project partners: RWS, ECN and SEAC EU contribution of 1. 4 M€ (Life program) Bi-functional: solar power plant integrated in a noise barrier Bifacial: orientation is east-west Energy for 40 to 60 households (200 tot 240 MWh/year) Start construction: 2017 Operational: 2018 RWS UNCLASS Rijkswaterstaat Solar Highways

Main objective EU Project Solar Highways Grant Agreement LIFE 13 ENV/NL/000971: “The main objective of the Solar Highways project is to demonstrate the technical feasibility and the environmental, social and financial benefits of using multifunctional constructive elements for building highway noise barriers, in which bifacial PV solution has been integrated (with functionality independent of the highway direction). Successful demonstration will simultaneously accelerate the use of PV and noise barriers along Europe’s highways, greatly contributing to achieve the EU objectives concerning climate change, noise and air”. 5 RWS UNCLASS Rijkswaterstaat Solar Highways

Sub-objectives • • 6 Demonstration of the technical feasibility Development of an technical-financial model Development of a prototype with integrated double-sided solar cells. A full-scale demonstration over a 400 -metre long stretch Monitoring during an eighteen-month practical test period Presentation of a business case for the barrier Communication and dissemination of the results and added value of the integrated PV modules RWS UNCLASS Rijkswaterstaat Solar Highways
