Best solar panels made overseas by US-based companies
For some homeowners, finding American made solar panels is a priority. While there are several fantastic solar makers headquartered in the US, finding panels that are truly made in America can be tricky.
That’s because there are American companies that manufacture overseas, and overseas companies that manufacture in America. And then there are companies that manufacture some panels in the US and others abroad.
BRAND – HQ LOCATION | PANEL | WHY WE LIKE IT |
Sunpower – San Jose, CA | A-series | Up to 22.8% efficiency, 25-year warranty, built-in AC inverter |
Sunpower – San Jose, CA | X-Series | Up to 22,7% efficient, extremely low degradation rate, 25-year warranty |
Best solar panels for degradation
Solar panels slowly lose efficiency over time through a process called degradation. This is a substantial concern to some homeowners curious about going solar.
However, the industry has been pleasantly surprised by the longevity of the solar panels manufactured decades ago, and the technology has only gotten better.
PANEL | DEGRADATION RATE | PERFORMANCE WARRANTY |
SunPower X-Series | 0.2% to 0.25% per year | 92% of minimum peak power after 25 years |
Best solar panels for efficiency
Another important solar panel feature is efficiency rating, or how much sunlight a panel converts into electricity.
Residential solar panels typically range between 15% and 20%, with the industry leading panels pushing 23%.
MANUFACTURER | MODEL | EFFICIENCY RATING |
SunPower | A-series | Up to 22.8% |
SunPower | X-series | Up to 22.7% |
SunPower | M-series | Up to 22% |
