Solar Panel Update
I just got a few pictures from my solar panel manufacturer, of the latest iteration. I asked to have holes drilled in the corners, which should make the panels easier to mount. I've also designed bamboo backing boards that the panels bolt onto, which will provide some extra protection, and it has extra slits and holes so that the whole contraption can be strapped, tied, lashed, sewn, and bolted onto just about anything you could think of.
I also decided to go with PET laminate panels instead of the cheaper epoxy coating. The PET laminate panels are rated to last longer, so I decided that was worth the marginal increase in costs. The difference is small enough that it wouldn't really affect the final price anyway, so it seems like the right thing to do.
Another minor but exciting change is the letters "Bootstrap Solar" embossed in the back. Yep, these are officially custom designed solar panels now.
