The nice thing about posting in the girl's room is that there's always at least one other that understands the kvetching and there is more commiserating and less "fixing." Sometimes it's more important to be heard.
Every time I think I've got the solar power thing figured out somebody mentions a new aspect that wasn't even on the previous list of considerations and then I'm back at the XXXXX eyes. I can't even remember what the latest one was because it just automatically caused the XXXXX eyes and emptied my brain of what I thought I knew. I can know what each of the different things are---volt, amp, watt, amp hour, blah, blah, blah---but stringing them together to figure things out? Ugh!
It's getting to the point where I think I'm going to accept that, just like how an internal combustion engine works, I'm not going to understand the solar power system before using one.
