Thanks for the solar panel.

The lead is short but you plan to extend it to 1.5m, good. For me the optimum would be 2m, then I could sit on a chair in the shade with the panel on the ground. It might be interesting to see how kids use the panel.

The panel is too tall to fit in most backpacks, I would be happier if it was a few cm shorter, even if wider or lower power. It looks like the case could be made a little smaller and still protect the panel.

The switching regulator in laptop SKU99 squeals noticably on the panel whereas the one in SKU104 is almost inaudible even though running at much the same frequency. SKU99 has travelled extensively with me and maybe the inductor windings have rattled loose.
