Not All Homeowners are alike: a Segmentation Model Based on a Quantitative Analysis of Dutch Adopters of Residential Photovoltaics.

Solar households do not all decide in the same way

In this study, we challenged the idea that homeowners who install solar panels are one uniform group. Residential photovoltaics are central to the energy transition, but campaigns often rely on the same broad message about savings or environmental benefit. We found that this approach overlooks important differences. People assess solar panels through their own knowledge, values, social networks, financial priorities and experience with energy measures.

We developed a segmentation model from survey data collected from 1,395 Dutch solar adopters in Parkstad Limburg. The respondents participated in a regional solar project, where coordinated action made installations more visible and easier to discuss. Instead of sorting people only by standard demographics, we combined educational or professional background—technical, financial-economic or other—with the degree of environmental concern. That produced five distinct adopter groups.

Different questions need different support

The groups differed in meaningful ways. Environmental concern influenced how people interpreted the benefits of solar panels. Technical familiarity affected how complexity, reliability and installation were perceived, while a financial-economic orientation often sharpened attention to cost, returns and risk. Social networks mattered differently too. For some people, local examples and advice from peers reduced uncertainty; for others, personal values or expertise were more decisive.

Perceptions of complexity, aesthetics and earlier experience with household energy measures also varied. Solar adoption does not follow one motive. Financial arguments, environmental values, technical confidence, local visibility and the ease of making a decision can all play a part, but not in the same mix for every household.

Our recommendation is therefore to move away from one-size-fits-all promotion. Different groups need different benefits, information channels, support and product options. Clear, objective and non-technical help can be vital for people who are interested but do not see themselves as technical decision-makers. Municipalities, installers and policymakers can also use social influence more thoughtfully by showing relevant local examples. The energy transition becomes more effective when we address people as different households making different kinds of choices.
