We have already discussed the awesome opportunities for vertical PV and the cultivation of biodiversity-boosting, air pollution-filtering green roofs. But there is an even more exciting facet of vertical PV that we didn’t discuss. The expected yields from vertical PV compared to horizontal PV are often higher than would be expected. Researchers from the Netherlands Organisation for Applied Scientific Research have conducted tests to find out why.

PV Magazine has published an article discussing the results of the findings in the study “Thermal model in digital twin of vertical PV system helps to explain unexpected yield gains” which has investigated this phenomenon. Ultimately, the results show that from lower operating temperatures these solar panels are able to produce better than expected results.

We have already discussed recently how a lot of the growth in solar PV generation is going to come from building more solar panels on flat roofs. As this is the governments focus in the UK perhaps we should all be considering vertical solar panelling as a way of not just meeting renewable electricity generation targets but also to cultivate more green spaces in our communities.
