Pros & Cons
What We Like
- Bifacial design captures up to 25% more energy from reflected ambient light
- IP68 waterproof rating — the highest in the portable panel category
- Adjustable 30-60 degree kickstand with integrated solar angle guide
- 220W front + 155W rear gives effective output up to 375W in ideal conditions
- ETFE coating for extended longevity and scratch resistance
Watch Out For
- 20.9 lbs with kickstand case — heavier than most foldable competitors
- Premium price at ~$399-449 for a 220W panel
- Bifacial rear gain requires reflective ground surface to be effective
- Only 1-year warranty — shortest coverage in this price range
