A light, high-wattage bifacial panel for owners of large power stations with a 50 V-plus solar input, especially over reflective ground. Owners of small or low-voltage stations should look elsewhere.
Amazon $549.99 ZOUPW $649.99
For car campers and RV owners with a mid-size power station who want 300 W from one panel without a 30 lb carry. Budget for an MC4 adapter cable.

- 300 W at under 19 lb, light for its output among suitcase-style panels
- Kickstands angle it toward the sun without improvising
- About 30 V open-circuit voltage works with most mid-size power stations
- IP67 and a 3-year warranty that covers output, longer than most portable panels
- MC4 output only, with no USB ports; the power-station adapter is sold separately
- Nearly 8 ft long unfolded, so it needs a clear patch of ground
- No independent output test yet
