Solar Power is essential to having the ultimate overlanding and bugout rig. If you're stationary for multiple days it'll keep your battery topped off so you can keep running accessories like a fridges and lights. The problem is that solar is a relatively unreliable power source. Time of day, time of year, cloud cover, age of panel, obstructions and how much debris is on your panel all affect your power output. Our philosophy with solar is to have more than you need. With our new Overkill Panel, even in suboptimal conditions you can still have a meaningful power output to keep your secondary battery full. We offset mount this new panel to create an air gap which keeps the panel cool, increasing it's efficiency and lifespan. The price includes wiring ports, and wiring to the bulkhead of your camper to a terminal block. If you purchase a Power Plate and battery, we'll fully wire it so you ready for your next adventure after your camper installation. Please Note: If this item is purchased after your camper has entered production, installation can only be completed at our headquarters in Wenatchee, WA, and a shop installation fee will apply.
