Looks fine, isn't working
Panels look perfectly normal but the figures say otherwise? Plenty of faults can't be seen from the ground. Tell us what's going on.

A solar installation can look perfectly normal from the ground while generation has fallen or an inverter is reporting a problem. Many faults are electrical rather than physical, so there may be nothing to see from outside.
If your Corsham system looks fine but the figures say otherwise, send us the details. An independent technician can investigate the system and explain what, if anything, needs putting right.
Lower generation is a good enough reason to enquire, even if the panels look fine.
The inverter may be reporting a fault that the panels themselves don't show.
Building work, new shading or a power cut can all be relevant.
You only need to describe the symptoms.
