Samenvatting:
In order to stimulate the use of PV (photovoltaic energy) in the Netherlands, the Dutch government offers a subsidy of 3.40 Euro per Watt peak installed after January 2001. It is hoped that this will facilitate the market for PV systems. The newly to be build houses form a substantial potential as PV carriers, but the existing housing stock is much larger. PV on existing houses has been promoted for several years now in the Netherlands, amongst others by utilities, PV manufacturers and the environmental organization Greenpeace. The new subsidy scheme will undoubtedly have a large impact on the PV demand for existing houses. However, it is doubtful whether the technology is mature enough to meet a large scale demand. In order to learn from experiences with small scale PV systems on roofs of existing houses, the Energy research Centre of the Netherlands (ECN) has set up a research project in which participating employees give access to the roofs of their houses to install PV systems. Fifty-nine ECN employees entered for participation in this project. This group provides a random selection of roofs, so that many different types of roof integration can be examined. Subjects included in the project investigations are: constructional aspects, yield and reliability of systems, institutional aspects such as getting building permits, aesthetics, behavioural aspects. The project was set up in 2000. In April 2001, the installation had been monitored and evaluated. Also the preparatory and initial findings and experiences of project participants have been registered through a questionnaire. The yield of the modules is registered by the participants.
