15.08.2023 | Myths and misconceptions can be highly persistent
Producing and distributing electricity – it’s a complex undertaking. So it’s hardly surprising that there are many myths and misconceptions about these issues in public discussion. We’ve collected – and corrected – some of the most common examples.
Expanding PV on roofs is a ‘no-regrets’ move. Naturally, we have to fit as many roofs as possible with solar installations as quickly as possible. This is the technology that enjoys the highest level of acceptance among the public (GFS study on behalf of VSE). On top of that, it does not require additional surface area but builds on existing structures. In terms of costs, large-scale rooftop installations on industrial buildings and PV canopies in car parks are particularly appealing. However, we need to do more than simply install PV systems on roofs because this would not supply enough electricity in winter. We also need to provide solar ground-mounted installations in the Swiss Plateau and in the mountains. Alpine installations in particular supply crucial winter electricity and are therefore considered vitally important. Furthermore, a quick look at the costs illustrates that large-scale solar installations often rank among the most affordable technologies out there. The bigger the installation, the better the economies of scale. We need a mix of technologies, including sources like Alpine PV and wind power. Both of these technologies supply plenty of electricity in the critical winter months.
