While renewable energy sources enjoy high public support, projects are rarely implemented without opposition. The term energy landscapes indicates that landscape change is amongst the most frequent issues. This study researched lay people’s perceptions of landscapes changed by solar power plants. The first objective was to discover how likely solar power plants are to be noticed in the landscape. The second objective was to determine the associations observers make when spotting a solar power plant. The data was collected by participatory photography and focus groups. Participants visited six solar power plants. The results show that they are highly noticeable and contentious objects. Participants who understood the landscape as a rural idyll disapproved of solar power plants, while for those who perceived the landscape through a utilitarian narrative, the (mis)fit of the solar power plant depended on its relation to the surrounding landscape structure. Landscape degradation was contrasted with low-carbon energy and developmental benefits. The results provide evidence on the interdependence of visual and non-visual factors and suggest improvements in planning and design of solar power plants. While the method gives a rich in-depth insight into landscape perception, it is also context dependent and needs further research to obtain more generalisable results. •A novel in situ method shows photovoltaics are highly noticeable landscape elements.•Laypeople mostly contrast energy benefits with landscape degradation.•Mimicking landscape structure improves power plant’s integration with the landscape.•Issues exposed by laypeople correspond well with impacts proposed by experts.
