Thank you so much for the insight. I discovered this this morning. When I was driving around at one point the panel was putting out 14w in the sun. Turned a corner and, whammo, it went away. So that’s totally what’s happening. I’ll be looking into a dc to dc system in the near future.
Where do you have all the room for those panels? I’m thinking of adding one more panel. The funny thing is I need the power mostly in the winter when the sun is low. In the summer don’t need as much power.
