It s possible to mount solar panels so that they oppose the slant of your roof though this solution may not be as aesthetically pleasing as they won t sit flush.
Installing solar panels on north facing roof.
The panels are installed on a north facing roof with a pitch that looks like about 9 12 37 angle up from the ground.
This means that they won t sit flush with your roof and will still produce relatively little electricity.
While it is technically possible to install solar panels on the north side of your roof they need to be mounted so that they oppose the roof s slant in order to generate electricity.
Panels mounted on a standard pitch roof facing east or west will produce approximately 15 less output than panels mounted on a south facing roof of a standard pitch.
Adding modules on the north side of the roof will not add much bang for the customer s solar buck and would qualify as solar malpractice in my book.
An ideal south facing roof here is pitched at 7 12 39ish degrees and the north side of that roof will produce less than half as much electricity.
Generally this isn t the best solution since these panels still won t yield much energy.
