Pros
- 25-year product warranty and 30-year output warranty from a large Korean industrial group
- Glass on both sides makes extra power from light reflected off a light roof or the ground
- All-black look suits a home roof
Cons
- Every store we found wants 10 or more panels per order
- At 54 lb it’s heavier than single-glass panels of the same size
- Costs more per watt than Chinese TOPCon panels of the same size, and no independent output test yet
