Pros and cons
Pros
Strengths called out by generated product content.
- Achieves an efficiency of 20.5% due to smaller solar cells reducing power loss
- Good performance and stable output even on cloudy days
- High performance, durable, and reliable according to user reviews
- Higher output power with module efficiency up to 21.0%
- Lower temperature coefficient and lower LCOE (Levelized Cost of Energy)
Cons
Tradeoffs and constraints to review before choosing.
- Approximately 300 watts out of each 400 watt panel, indicating some power loss
- Power loss of about 5% mentioned in discussions
- Wiring and interconnection methods may be suboptimal or confusing
- Some users express concern about the wiring setup and interlock design
