Solar panel for 12v battery

[Rvtraveler]

I’m in the market for a solar panel to keep my travel trailer battery topped off when not being used. Any suggestions would be appreciated.

First, you need to determine the amount of electricity that is needed for an autonomous life. To do this, add up the rated power consumption of all the equipment you want to use, the sum will be the peak consumption number. By no means always you will have all the equipment included in a unit of time, so the calculation should be carried out only with the equipment that is used most often. For example: charging for a laptop - 90 W, lighting - 100 W, in total we got ~ 200 W per unit of time. Having information about power consumption, you can go to the selection of solar panels directly. Panels are usually supplied with kits, with a controller and the necessary wires and fasteners.

I've got two nrgGo 100W Solar Panels, and that's enough for me.

Solar panels are recommended to be connected to the battery, directly, through a 5A fuse, which is also needed to disconnect if there is an overcharge or if charged from 220V. But I would leave this matter to a specialist.

I do not recommend anything just to maintain a battery in storage less than 100w. these battery maintainers are a waste of money. Never connect a panel directly to the battery when you are not there.

I understand feeling that no amount you spent will keep up with usage as you camp. however the price of panels now days can't be beat. You will still spend money on a controller so why not up size? really the work is much the same.
