Yes, but slowly. A 350W portable solar panel produces roughly 1.4-1.75 kWh per day in full sun. That translates to about 3-6 miles of driving range per day for most EVs. The main use of portable solar while camping is to offset your overnight Camp Mode drain (8-12 kWh), not to fully recharge your driving battery.

Camp Mode uses about 8-12 kWh overnight in mild weather. To fully offset that, you would need roughly 5-8 portable 350W panels in full sun for an entire day — impractical for most campers. A more realistic goal is to offset 20-30% of your overnight drain with 1-2 panels, reducing your net battery loss.

Look for monocrystalline panels with at least 22% cell efficiency (like the common 350W folding panels). Key features: waterproof, foldable for storage in the trunk, and compatible with a portable power station that has a pure sine wave inverter for Level 1 trickle charging. The panel should include an MPPT charge controller for maximum efficiency.
