Don't forget, "boys", women can do things, too. I installed two systems...one very small in the barn and one small for the house. The 16 panels for the house are wired through a combiner box from which 4 wires come into the garage. From there, there is a breaker cut off prior to each of the two Midnite Solar Classic 150 charge controllers. I have an Outback inverter. Initially, I used a forklift SLA battery but have recently converted to LiFePO4 batteries. They are great...so far. For freezing temperatures, they need to be housed with insulation so that is a project in the making.
I installed a new service panel and moved the breakers for the outlets and devices I wanted to run on the solar. It was just a matter of moving the wires from the original service panel over to the new one.
The system at the barn will power lights and the chicken waterers. The house system will power 1 refrigerator, 2 freezers, TV, etc., and several outlets for lights. I have a transformer to get 240V but I haven't done anything with that yet. If connected, that would power the water pump, but I doubt it would do much for heat/air as the system is not large enough.
My motivation was due to power outages. The money saving on the electric bill would not be much since heat/air, oven, dryer are the biggies. I only run small things. I do have a Honda 3000is if necessary. When there was a lengthy power outage a few years ago because it was rain/snow, there wasn't enough sun to charge the battery so the Honda was a real lifesaver. I also have a fireplace. But, as we all know, that's a lot of work!
So, there it is. I did this in 2012 and it still is running so I can't complain. Plus, the house hasn't burned down yet! Lots to be thankful for.
