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, obstru

This fixes many issues with low or exhausted batteries. However, I wonder how well it will work in winter?

Before we received the Lone Peak, we would take portable solar panels and spend the time moving them throughout the day for our solar generator. The "Overkill" panel eliminates the need for any additional panels, frees up storage space that panels would otherwise take up, and provides a solid solution to provide power. Combined with a DC-DC charger for the truck 12v and a separate storage system, you can have enough power to run a number of appliances and personal electronics.

Super impressed with the overkill panel. Even producing a decent charge in the PNW winter!
