There is a lot of new research showing that vertical bifacial solar panels are more efficient, are exposed to more solar energy, and have a better spread of the energy through the day. I would expect the effect to be even bigger in the UK which is further North, especially in winter. Though it is almost certainly too late to consider for the current farm is something Ripple should consider.
There is also a benefit that certain crops can be grown between the panels without impacting them.
