I have Qty (3) 320 watt rigid SunPower panels on a boat I recently bought:
These are only 3 years old. Spec sheets rates them 90% output at 12 years. In full sun yesterday (angled a bit towards the sun which is lower this time of year in Florida) I was only getting 640 watts.
Going through Victron charge controllers. What gives? Is the sun just as not as powerful in the winter? Perhaps the wire is undersized? Is this normal?
Any input would be appreciated.
