Yes, there are specific brands of solar panels known for having lower degradation rates. Here are a few examples:
- First Solar: First Solar claims one of the lowest module degradation rates in the industry, at about 0.2% per year. This is significantly lower than many conventional crystalline silicon panels, thanks to their Copper Replacement (CuRe) technology.
- SunPower (now Maxeon): SunPower solar panels, now under Maxeon, are known for having some of the lowest degradation rates in the industry. They guarantee that their panels will not lose more than 8% of their original DC power output over 25 years, which is significantly better than the typical losses of conventional panels.
- Panasonic: Panasonic’s EVERVOLT Black Series solar modules are noted for their industry-leading conversion efficiency and low degradation rates, although the exact rate is not specified.
These brands focus on using advanced technologies and materials that enhance durability and performance over time, contributing to their lower degradation rates compared to standard panels.
