ANOTHER D*** Solar Question!!!!

I have a 100 watt portable unit because I only boon dock 2 weeks a year. The rest of the time I am at RV parks. At home I am plugged into AC power. If you plan more than that you really need to get much more power than your 10 watts. 100 watts would be good for keeping your RV in storage. For serious solar you need to be looking at 30 to 60 amps. There are some serious solar RVers on the forum that will be able to help out. Don't mean to be critical of your 10 watt unit but that is typical about sales in todays world. Current times voltage gives you power of the unit. watts divided by voltage gives the charging current available on your unit. i.e 830 ma. or .83 amps Most cheapo battery trickle chargers will furnish 2 or 3 amps. JMHO. You need to decide how much you will be off the grid. If very little, like me, a 100 watt portable panel will work out. If you do lots of off grid camping a much larger system will be needed. Hopefully one of the solar guys will make some more suggestions.
