My thought you are wasting time and money for the small amount of energy you possibly save.

Sometimes it is just about tinkering. I certainly don't expect to notice any change in my propane expenses. But if it works, I will like seeing my amp meters show full solar harvest potential happening even when it isn't needed right then for the battery charging and other loads. And I will have learned something about off-grid solar design to apply to future projects.
