Pinball,

I have already done an analysis on my site (using PVwatts), have gotten quotes and it looks like I can get a system for about $1.70 a watt for a 10 kW system (self install).

Need those before I apply to USDA or NRCS.

I do a lot of summer irrigation and that eats up a lot of kWatts.

The purpose of the graph is that I can predict, rather accurately, my winter heating costs. From the graph, it looks like two houses and barn office costs me about $432 a year for heating.

Geothermal heat pumps are a simple no brainer for return on investment. Even more so if you rig one up.

Steve
