Right Joe. And if you take their optimum voltage and current. 18.5v*2.7=49.95w which is what an MPPT controller is supposed to attain. Optimum being the key word.

If you want to see 50 watts, you need a MPPT controller that is essentially a DC-DC converter. Running my cheaper PWM controller I never get the full 50.

Clearly renogy is providing nominal values for marketing purposes. You can't fit all of the specs in the amazon headline.

Output should be stated at the working output voltage. That is more like a 30 watt panel when comparing to other brands whose quality factor includes truth. =-O Bill Bina On 12/1/2016 8:15 AM, Della Barba, Joe via CnC-List wrote: This is mine: https://www.amazon.com/Renogy-Watts-Volts-Monocrystalline- Solar/dp/B00DVPPFDS/ref=sr_1_1?ie=UTF8&qid=1480598077&sr=8- 1&keywords=50+watt+solar+panel 50 watts - $80. I have had no issues at all with it. Joe Coquina _______________________________________________ This list is supported by the generous donations of our members.
