Dave,
I added a GoPower 100 Watt system last summer at the same time I added a new Isotherm Ref. System. I found that the most I was getting from the panel was about 3.5 to 4 amps according to the GoPower controller. Was still having to run the engine a few times a day to keep the beer frosty. So this summer I added the 100 watt GoPower expansion panel and I am now seeing numbers as high as 9 amps. Good system and not too pricey. I run a Sportsman 8d for house 1, a Sportsman Group 31 for house 2 and a Sportman Group 24 dedicated battery engine. Boat just did a nine-day cruise and all worked well. Best of luck!

Specifically evauating a battery upgrade and potential top-up-charging. Based on what I've read, a 100w panel would conservatively contribute 400-500w daily (average) in summer and be enough to help extend my "off the grid" time. I am on the North shore of Lake Ontario, Toronto area. Does anyone have any real-world data or experience with the actual charging capacity of a sailboat mounted solar panel? Would like to factor this into my decisions. Many thanks! Dave Windstar 33-2 https://cncwindstar.blogspot.com/2019/09/going-off-grid-charging-and-battery.html
