In the northern hemisphere the ideal location for panels is to the south. These face directly toward the equator and as a result get the most sunlight throughout the day. In simple terms solar panels on a southerly facing roof get exposure all day maximising electricity production.
Easterly and Westerly facing roofs broadly speaking produces electricity in either the morning or afternoon receptively. If you have roof that lies east west and you are able to put panel on both you can get a very good result. You may need a few more panels, but since the price of panels is relatively low in comparison to the cost of the complete system this is only a minor consideration.
If you can only put panels on the east or the westerly roof then you can still benefit from solar but the panels exposure to sunlight will be more limited. To what extent depends upon multiple factors such as roof pitch, exact orientation, geographical location to name but a few.
Which brings us to Northerly facing roofs. These face in the opposite direction to the equator (well they do in the northern hemisphere...) and as a result get very little in the way of sunlight. Generally speaking its hard to make roofs with a predominantly northerly aspect viable to solar electricity generation.
