We recently visited a large wall-mounted solar installation in Buckinghamshire to explore why vertical solar panels can outperform roof-mounted systems in the winter months.
In this video, we explain how wall-mounted panels can generate up to 30% more during winter, thanks to their improved angle relative to the low winter sun. We compare performance data from systems in Reading and Newcastle, discuss the science behind solar incidence angles, and highlight where and why vertical mounting makes sense.
We also cover the practical benefits – from easier maintenance and cleaning, to cheaper installation with reduced scaffolding, less cabling, and no need for bird protection. And as an added bonus, wall-mounted panels can even protect your brickwork from the elements.
If you’ve got a large south-facing wall, this video might just change the way you think about solar.
