2 solar arrays and one controller

Hi

I have identical polycrystalline solar panels mounted on opposite pitches of my roof. I am running them into my solar controller which has only one solar input.

I know the text book answer to this is that it shouldn't be done. To optimise solar performance both panels should face the same direction.

My question is... Why not? Is it dangerous? can i damage the panels or the battery? any idea what kind of performance loss to expect in this configuration?

thanks for any help

I dont think there will be any damage but only efficiency will be low..Were you able to find the right answer for this? Waiting for reply thanks in advance:)

Re: 2 solar arrays and one controller

would be nice to have some numbers.....but there should be no problem if you wire them in parallel and the controller can handle the current output....
