Pros and cons
Pros
Strengths called out by generated product content.
- First Solar Series 6 modules are certified for reliable performance exceeding IEC standards.
- The Series 6 modules are designed for high lifetime energy production.
- Series 6 Plus offers higher performance and wattage compared to Series 6.
- Modules are suitable for large-scale solar projects with optimized design.
- Manufactured using proven CdTe technology.
Cons
Tradeoffs and constraints to review before choosing.
- Efficiency is lower than crystalline PV panels, resulting in fewer watts per square foot.
- High voltage can require a decent MPPT to handle the electrical characteristics.
- Panels may be more hassle to install and manage due to voltage and mounting considerations.
- Some users consider them more trouble than they are worth unless purchased at a lower price.
Notes
Context that does not fit neatly as a pro or con.
- First Solar is one of the last US-based solar module manufacturers.
- Panels are not the most powerful in the lineup but offer a balance between affordability and performance.
- Panels have a wild voltage that can make string design challenging.
