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.
Installing solar panels on north facing roof.
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.
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.
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.
Generally this isn t the best solution since these panels still won t yield much energy.
The panels are installed on a north facing roof with a pitch that looks like about 9 12 37 angle up from the ground.
However the economics of installing solar panels on a roof that does not face the south still usually stack up for the homeowner.
Even if you have a north facing roof you still have some solar options.
