Using Go Power 10 Watt Solar Panel Charging System to Trickle Charge 2 AGM 12V Batteries

Updated 04/25/2019 | Published 04/22/2019

Question:

Will a 10 watt solar panel be enough to trickle charge two AGMs? Should you hard wire one 10 watt charger per battery? Is there any worry about over charging when in storage?

I spoke with my contact at Go Power and he said that under good sun conditions and with limited to no power draw, the 10 Watt Solar Panel Charging System # 34273836 that you referenced should be enough to provide a sufficient trickle charge to your 2 AGM 12V batteries. The potential issue comes with a couple cloudy days in a row or when you draw more power from the battery as one 10 watt panel is going to be just enough without much wiggle room.

Because of this going with 2 of the panels, 1 for each of the batteries, will be your best option to ensure a sufficient charge. You do not need to worry about overcharging the batteries with this setup while the trailer is in storage.

I have attached a short video review on this kit that you can check out as well.
