I am looking to buy a solar panel to charge a 12v battery for a electric fence that I have. The fence is temporary and I would like to use this same panel for another project in the future. My question is if it is ok to use a solar panel that is overpowered for the application if the proper solar charge controller is used? I am looking at purchasing a Renogy 100W (5.62 Amp Optimum Operating Current) solar panel to use on my small electric fence (15 Mile Electric Fence Charger). I know that this is a overkill but I would like to use this same panel in the future on a solar water well system I have in mind (to keep a constant flow of water in my pond). Does anyone have experience with this and know if I would be okay going with this size panel?
