I got a 100w suitcase solar kit with 10w built in controller and have already ordered a 30w Solar30 controller from ebay. I plan to bypass (remove) the built in controller, mount near the battery bank to minimize loss. I will buy a 100 watt panel to combine with the suitcase kit using a homemade stand. I will have the capacity to add a third panel if I want. The DW is allowing no panels on the roof of her fiver. LOL
However, if we were to boon dock in one spot for a few days, I could lay the panels on the roof with stand offs. Or go with two 100w panels for that and keep the suitcase as is for reserve power and portability. It is still up in the air. So many choices.
