Should I go for Solar or Not.. the ultimate dilemma!

"Third, if you don't have any shading issues then you don't need Solaredge." This isn't quite true. If you are mixing a number of orientations and pitches then you may still need a Solaredge system even if there are no shading issues. Also I've had a failure with my system and having Solaredge made it very very easy to find where the problem was. This isn't a reason to go with SE on it's own but certainly a potential benefit.

A flat roof shouldn't be a problem for an installer. A specific panel mount is used and weighted down. I'm told it's straightforward. HOWEVER - I was advised against as it creates pressure points on the roof which may potentially cause leaks. If also makes things complicated when the roof needs recovering. If the flat roof is the highest part of the building then you are increasing then you are extending above the current roof line and so need planning permission. If there is existing roof above the flat section then as long the panels remain below that you shouldn't need permission.
