Solar Panel Size Chart for RVs, Vans, Campers

Here’s a size chart for what solar panels you need by size of RV/van/camper & how many Dakota Lithium batteries you have.

To connect solar panels to a lithium battery you will need a lithium compatible solar charge controller (a deep dive on RV electrical systems is available here). To connect lithium batteries to charge from an engine’s alternator you will need a DC-DC battery charger. Every Dakota Lithium battery includes a free lithium battery charger for charging via shore power.

For a complete lithium power system kit that includes the solar panels, batteries, chargers and accessories needed check out the recommended off-grid power systems.

An example of 500 watts of rooftop solar. Three larger 150 watt panels plus one smaller 50 watt solar panel on the roof of this RV generates more than enough power for the 4 Dakota Lithium house batteries they are charging.
