Location PVNB: highway or railway, densely populated area

On those locations, noise barrier needed

Advantages of decentralized electricity generationKarger and Hennings, 2009

Limited area available to install ground mounted PV, constraints regarding rooftop PV

5. Conclusion

Stakeholder Benefit

Government Motivate private sector to invest in PVExtra amount of renewable energy

No additional space

Private investor Profitable investment

Residents Less noise nuisanceIncrease in real estate prices

PVNB could be a fruitful public – private partnership for the government, residents as well as private investors. Consequently, it would be beneficial to promote the technological development and the installation of PVNBs for example via implementation of

flexible governmental legislation regarding investment conditions of PV sound barriers.
