DenkMalSolar – Aesthetic integration of solar energy on sensitive buildings

What options are there for implementing well-integrated solar systems that are also suitable for listed buildings (special architecture or historic interest)? What technologies are available for this, what do they cost compared to "ordinary" solar energy systems, and do they deliver the same yield? These questions were investigated by SPF on behalf of the Office for Energy and Transport of the Canton of Graubünden. As a result, a catalog of available solar technologies was published, which is also made available online here (in German).
