You loose performance at noon/summer, when you are likely to produce over your demand anyway.

But during winter/rainy days, when you are limited to diffuse light, they deliver the same output.

The point is that panels are so dead cheap now, that efficiency of orientation is no longer an issue.

Approximately how much does a panel generate from diffuse light compared to direct sunlight?

[pintxo]

I‘d say around 10%+.

Over a whole month, peak summer production here is 1.4MWh, winter is 0.14MWh.

Thanks. That's not great: I need more energy in winter...
