Pros
- Bifacial design captures reflected light on the rear side for up to 28% more energy on reflective ground
- Up to 25% front-side efficiency with N-Type TOPCon cells
- IP68 fully waterproof and dustproof rating
- Currently $250 off EcoFlow's $549 list price
Cons
- Bifacial gains depend on a reflective surface (sand, snow, light gravel) — minimal benefit on grass or dark pavement
- At 15.4 lb it's noticeably heavier than the 110W panel
- Glass-inclusive bifacial construction can be more fragile than single-sided ETFE panels
