BREAKING NEWS UPDATE ON THE SOLAR PANEL:
(alternate title: "Sometimes I'm so dumb, I amaze myself")
I know some of you have waiting to hear how well my solar panel performs. Well, it turns out that all my previous reporting was way off. I must have blown the fuse when I first installed it, and so the panel was never charging the battery.
On the last three trips we were in the shade, so I didn't expect to see any huge results. So, when the battery level stayed pretty constant, I figured the panel was keeping it topped off - actually, we were just hardly using the battery.
So at IRG, the sun had been beating down on the panel for the whole day, and the bettery level had stayed at 11.9 volts. Finally, I asked Craig if that was normal (he and Betsey were at IRG) and it took him all of a minute to find the blown fuse to the 12v outlet in the front storage box. (That's where I ran the cables from the solar panel.)
It's amazing how much better a solar panel will charge your battery when there isn't a blown fuse inline. The battery level climbed from 11.9 volts to 13.4 volts in about 5 minutes. I'm pretty sure, that even in the shade, the panel is going to do very well.
So now, with all this infinite power, we should be able to run the 12v fridge for any length of time. (another option to buy... haha)
Moral: Check your fuses if things aren't working. If you think things are working, check them anyways. Maybe things will start working WAY better.
