The distance between photovoltaic panels and the edge of the roof

PV on a flat roof, how far from the edge?

I''m trying to get a new PV system installed, on a flat roof. I''m about to apply for planning permission, but can''t find any solid info online about restrictions in terms of how far from the edge the panels must be. I assume this is a building regs thing rather than planning permission, but I''ll need to be on the right side of both aspects I guess.

How many solar panels can I fit on my roof?

X gives you the distance from the apex down to the edge of the roof. STEP 3: C x X = AREA OF ROOF. Multiplying C by X will give the area of roof space available. You also need to deduct the 30cm around the edge of the roof on which the panels cannot be fitted – this area will depend on the type of property – detached, terraced etc. Flat roofs

Location of solar panel 3 feet from edge of roof.

If the requirement to maintain a 3 ft clearance between the edge of the roof and a solar panel is in the code, then I am struggling to find it. The rationale that I have discussed with other code gurus is for the purpose of allowing fire fighters to walk around the panels rather than on top of the panels.
