Where should a PV array be sited?
Ideally a PV panel system should be sited on a south facing roof or ground mounted support system at a 30 degree to 40 degree pitch. However, an east or west facing array can also have up to 85% optimal performance.
The size of the PV system will be tailored to suit your needs.
Do I need planning permission?
In most regions, PV panel systems are viewed as permitted development items that require no planning authority approval, so long as they are installed within certain guidelines.
Shading
Any object throwing shade on to a PV panel will cause a lowering in the performance of the array and must be taken in to consideration by your chosen installer when calculating the anticipated energy output for your system.
