Referring to the boiler and solar collector manufacturers literature it was discovered that the ballast installed beneath solar panels was inadequate. The system used relies on the solar panel frames being securely bolted to concrete or similar materials of sufficient weight to prevent panels from being lifted and moved in strong winds. Calculations showed that the roof structure would not cope with sufficient weight to prevent the panels being lifted and moved horizontally so a separate framework will be added to attach the frames to the parapet.
Another problem encountered has been damage caused by seagulls pecking through the insulated sleeve to the pipes to the solar panels, exposing the stainless steel pipe
and control cables. It is thought that seagulls that are used to scavenging food from black waste bags instinctively peck at anything black, plastic and shiny.
The slightly experimental solution has been to disguise the insulated sleeve by wrapping with insect and bird mesh.
