Goal Zero vs PowerFilm:120 Watt Portable Panel Comparison
I compare two portable Solar Power arrays by Goal Zero and PowerFilm Solar using the West Mountain Radio Computerized Battery Analyzer IV’s power curve profiling.
Testing occurred between 12:10PM and 1:30PM on Saturday August 24 under completely clear skies in 80ºF weather.
Both arrays performed well and fairly close to one another. The surprising thing was that both panels only output around 90watts in my test setup. I will reach out to both manufacturers to get their take on this.
