You can get 5 watt chargers cheaper I would have thought?
It can (5 watts) make about 1/3rd of an amp in full sun on the equator. Say 250ma in summer here in the UK.
Thats only on high summer clear days. And only for a few hours. So it should be fine. Especially when overcast / winter. And it wont do anything at night. So shouldnt overcharge. If I lived in arizona I might be worried though.
