Thanks for all the feedback. The problem we have got is that we live in the
Alps so the sunlight in the winter is quite short as soon as it dips below
the mountain the sun is gone.

However we do have a south facing roof so it does get a fair bit of sun.
How does the snow affect it??

thanks again

For roof mounted panels, snow will prevent any output at all, as it
blocks the light. For wall mounted panels, snow increases output since
you've got sun and skylight bouncing off the snow onto the panel as
well as direct light.
