Siting of solar panels

[Percyprod]

I'll be building a shed this year, and want to use solar panels with a leisure battery to provide lighting via 12 volt led lamps. The shed will lie north to south, and I want to know if I fit 2 panels, one on the east facing sloping roof and one one the west side, thy will get different levels of sunlight on a sunny day as the sun rises and passes over head. Will this matter? It's a large USG shed, I have a 120 ah battery, and thought I may get another, connected in parallel with 2 X 80 or 100 panels. Any info will be appreciated.

A E/W split will generate a little less than a south facing array. But it will generate for a little longer.
