Several questionings of inhabitants, tourists, architects, planners and representatives of monument protection authorities were carried out in the course of the project. The results confirm the important and so far underestimated role of design aspects as acceptability factor.

Acceptability and Transferability
In May 2003 an international workshop with the title "Acceptability and Transferability of Photovoltaics" was organised by PVACCEPT in Berlin. Participants were, besides the members of the PVACCEPT consortium, external experts, members of the research centre FACT at UdK Berlin, and the European observers.
In the first general questioning
every second interviewee in Italy and every tenth in Germany
considered the photovoltaic modules available on the market
as "not aesthetic";
two thirds of the interviewees in Italy and three quarters of those
in Germany were of the opinion that installation of photovoltaics would
be possible even at historical buildings if the technological elements were
A second questioning concentrated on architects and decision-makers from
public bodies; furthermore tourists and local population were questioned with
regard to the built PVACCEPT demonstration objects. One of the results of
this second study was an excellent acceptance of these objects both
in Italy and Germany.
Results of the workshop concerning acceptability:
Design is an even more important acceptability factor than anticipated.
Design also has to comply with the requirements of sustainability, i. e.
environmental and economic aspects.
Design influences the type of building integration of photovoltaics,
which on its turn influences the environmental and energy efficiency.
Results of the workshop concerning transferability:
The local situation has to be considered, which means also to deal with
different target groups.
Important intermediaries for the dissemination of the technology are
architects and craftsmen, but also administration representatives
Knowledge and awareness are important factors. Therefore education
and training with respect to photovoltaics are necessary to raise
the acceptance of solar technology in general.
Making use of the demonstration potential of "virtual reality" supports
the necessary activities to convince the public, administrations, and
Barriers, which stand against a wide dissemination of photovoltaics,
are costs and bureaucracy. These barriers have to be investigated
before project implementation.
Local authorities play an important role as multipliers.
An additional chance for fostering the dissemination of photovoltaics can
be seen in city marketing or the "corporate identity" of cities.
Also tourism is an application field for photovoltaics. In this area there
exist already positive initiatives from which to learn.
