Rated 3.5 out of 5 by 2 reviewers.
Rated 5 out of 5 by bobm needs to redo his math bobm might want to redo his math. The specifications clearly state an amperage of 7.92A and a voltage of 49.4V giving us a grand total of 391.25W. Looks pretty spot-on to me. I'm planning a fairly sizable array on a new house and I'm not seriously considering these panels. March 22, 2012
Rated 2 out of 5 by Wattage output You say current is 8.15 amps & voltage is 36volt Wattage is current times voltage therefore I olny see 294 watts December 15, 2011
