LOL!! EV range not only reduced in cold, ALSO reduced in HEAT!!

Someone, please. Show me how a solar electric home system pays for itself. I would very much like to see the math. I would consider installing one on my property if there was a pay off that wasn't longer than i want to own the home.
ANYONE?????
There is at least 1 DIY Solar Group on facebook, and a DIY Solar Forum (can't find the link off hand). There are really cheap solar panels out of Texas, bargain used charge controllers and inverters, and innovative ways to tap the battery's DC to directly drive loads (LED lights, BLDC motors to replace ACIM, etc). Used batteries are available as forklift lead acid or EV lithium ion. In all, you could have a solar system for <1/4 of the typical professional installation -- but you have to do your homework. Doing your homework and the work yourself makes solar feasible.
