Im in Victoria, Australia so 6 hours works for me and i agree you dont get 12 watts from a 12 watt solar panel, unless you run a GOOD MPPT system.Re the 1 for 10 watts i have read the same from quiet a few RV people.

So, this circuit will work when I have peak sun light, right? And if I have ambient sun light, not directed to the solar panel, what happens? For example when the solar panel provide me 10 Volt instead of 12 Volt?
