Ask PYS: Power

Bruce – Solbian Panel Install Voltage, on Apr 10, 2014 asked:

I just finished installing the Solbian 125 watt panel I purchased from PYS. Photo is attached showing how I installed it. On a drizzly overcast morning here the panel still delivered 18.25 volts! Thanks for all your help in making this important purchase for my sailboat easy and worthwhile.

What is the amperage and voltage that you measure after the MPPT controller? 18.25 Volts is the right voltage from the panel, but the controller will bring the voltage down to a suitable voltage (about 14VDC) for the battery.

You should remove the plastic layer on top of the panel. The plastic layer was there to only protect the panel prior to installation.
