Thanks. I ordered 2 - 50W flexible panels with the discount and free shipping. I just want to maintain my flooded batteries while my Avenue is sitting and the factory 25W (don't laugh, I know it's tiny) is not up to the task.
(Just a note: The old flexible panel is 7 years old and remarkably still working fine as on a few really sunny days I've seen 23W registering on my Victron 75/15 solar controller. However, that's still only 1.3A max and I've only seen it occasionally. It's usually much less and around .5A of charging into the batteries. It can never get the batteries into float and after a week they are consistently resting at 12.45v overnight.)
Using a flexible panel is really my only alternative due the curve of the Avenue's fiberglass roof. Plus there is extremely limited space, but the new 50W panel is only two inches wider and four inches longer so it fits there.
My reason for buying two panels was if the other one should fail in a few years (as flexible's are reported to do), I'll have an exact replacement that is plug and play and won't require the drilling of any additional holes. Maybe I can even find a loication for the other 50W to boost my solar charging to 100W.
I've equalized my flooded batteries regularly and keep them properly filled. If I can get 2-3 amps consistently for 3-5 hours per day with the new panel, shouldn't that keep the batteries topped up? If not, maybe it's time to replace them.
