Jim, your usage sounds about what we use daily, around 25-30 amps. I had a Renogy solar suitcase which helped, but couldn't quite keep up and we'd resort to running the genset on day 3 or 4 while off the grid. In Feb of this year, I installed a Renogy 150w Mono panel on the luggage rack on our AF 996 and connected it to a TriMetric SC2030 controller coupled with a TM 2030 Battery Monitor. It has been a perfect combination so far with a vareity of conditions from shade, cloudy days and full sun. I built mounts to allow tilting, but it has worked so well that I haven't bothered to climb up on the roof. We have carried the 100w portable, but so far haven't used it. That will probably change this summer when we are parking in shade, but the 150w panel seems to really put out the power, even on days where we don't see the sun. Our Lifeline 6v batteries are very happy and I expect to get many years of service from them as we see 100% charge daily.
