So, the prices are simply too good for me to ignore, so I stopped ignoring them and pulled the trigger. I'm getting some used panels for $0.12/watt plus shipping, so around $1,200 for 6.6kW of panels. These are "C" grade, so they've got hairline fractures, etc. As a result I'll probably have to sort them out according to their characteristics and build my strings from there.
With some modification of our schedule, we can probably lower the battery storage needs as well. I plan on keeping the grid to run on one circuit primarily for 240v appliances, then pulling off the majority of the 120v off onto a separate battery powered circuit. I have a 48v 5.5kW sustained 15kW peak inverter, so my costs after this will be batteries and a charge controller.
I'd like to use used Leaf or Tesla cells for the battery packs. I hate lead acid with a passion, and want to avoid the hassles of that ancient tech if possible.
