  • Reading Solar Panel Specifications Label

    Can anyone explain to me the capacity of this panel. I can't understand the specifications as stated on label.panel.jpg

    It is 55Watts?

    Thanks, Dave

        Actually saw better than that last week while looking for a ground fault on a new install.

                Just where to you go to get something like that calibrated (other than back to the manufacturer?)

                  The thing is brand new. There may have been some cloud lensing as it was a partly cloudy day.
