Do solar panels need a roof edge?
Even when manufacturer guidelines don't require it, installers still need to leave enough space at the bottom edge of a roof so water flowing down solar panels doesn't overshoot the gutter. It is also good practice to leave at least 20cm between panels and roof edges.
How close should solar panels be to the roof?
You'll also need to take into account how close the solar panels can be to the edge of the roof as some clearance is necessary. Panels should never extend beyond the edge of the roof as the wind can be stronger there. To keep your property safe, and to abide by MCS regulations, we try to maintain a margin of 30 cm around the panels.
How many mm should a roof panel be?
The 200-300mm requisite is simply to allow for a slate / tile / and a half to be fitted to the edges and be finished accordingly, eg so the in-roof trays can be part of a robust weatherproof install. FYI, a few installers put the bottom of the panels too close to the gutter and the rain overshoots the gutter. One issue to watch / mitigate against.
