It seems like last month it was taking my solar panels until 2 or 3 o'clock in the afternoon to charge the Arctic Fox's batteries back up to 14.4 volts, which is full charge, and now they're reaching that level before lunch. My electric usage has stayed the same the only major difference is the sun is getting higher in the sky every day.
That's probably not something most folks pay any attention to but since I live on sunshine everything the sun is doing becomes important to me. Like for instance I've noticed that during the months when the sun is low on the horizon, even when the sun reaches its highest peak, which I believe is referred to as Apogee, which is ancient Greek for "as high as she's gonna get", I can see the sun in the kitchen window that's on the back of the Arctic Fox, but now the sun is way above the kitchen window which means, since I'm always facing north, that the Arctic Fox either has four flat tires or the sun is higher in the sky.
That phenomenon is why most normal folks have solar panels that tilt so the sun will always be hitting them at the proper angle to give the most charging. Not being afflicted with very many normal genes, but having an overabundance of lazy-bones, I decided early on that tilting panels was way more work than I wanted to get involved in so I put a couple of extra panels on the roof that would make up for the sunshine I was missing during the winter with the panels laying flat and called it a day.
And now In the almost 5 years of living with the panels that way it has worked out perfectly.... Which shows the wisdom of theboondork's rules for life number 18 which says, "hard-working people are happy to continue doing everything the hard way, it's the lazy people that find ways to make life easier.
