SunPower’s E-Series modules take the top 3 spots in the respected Photon field test. One of SunPower’s claims is that their lower temperature coefficients produce better real world results than can be demonstrated in the lab. These field tests are more third party support for those claims. Way to go SunPower! We are happy to be partners with this company.
