Solar / Re: Output of solar panels depending on slope and azimut

You will never be short on power in June (at our location 50 deg North) but you will be quite short in december, when east and west facing panels make the least amount of power.
For a fixed array, the old rule of thumb is south facing with angle matching your latitude. That gets you set not bad.
I find it better to have a 2 position tilt. 65 deg winter 20 deg summer.
Net metered grid tie is a whole different deal, and then the summer output maximising setups might work out better.
