I guess what I'm saying is that steep-angled panels are more dependent on direct sun at a complementary angle than shallow-angled panels which can better gather diffuse light from the cloudy sky.

Because of the angle of the sun in summer (53 degrees plus 26 degrees = 79 degrees) the math shows that a 15 degree North Facing Roof produces MORE TOTAL kWh output that a VERTICAL South facing Wall ......... Just run it through PV*Sol
15 Degrees North give an angle of incidence from panel to the Sun of 64 degrees
Vertical South facing gives an angle of incidence from panelof 21 degrees
Just as panels oriented towards the sun will tend to gather more, panels oriented towards the sky will tend to gather more when the whole sky is light cloud but no sun.
Having said all that, getting paid 43p to generate and 3.2p for 50% export, more than makes up for buying at 10p... AT THE MOMENT..
FB is suggesting a 20 degree mounting angle which would get more benefit in the summer than the winter, regardless of diffused light.
