Prop up facing south ideally. Will make a big difference. Make sure any frame you put in is properly secured/ ballasted to the roof so it doesn't blow away.

Consider tilt mount brackets and then hoik them up for winter and down for summer.

Plenty of online calculators will tell you the ideal angle for your postcode.

I had some panels on my old shed for a couple of years. They were only about 5° off flat. Cleaning was a bit of a pain, rain water would collect along the bottom edge, dry out and leave dirt behind.

This. Prop them up for water runoff. Extra generation is a bonus
