Yea, solar electric is expensive at about 24 cents per kilowatt compared to 8 cents per kilowatt for grid power. I can get that down to 14 per kilowatt with the tax credits and local rebates but it is still a long term deal. My roof is needing to be replaced and that would have to happen first.
I have an overhang that doesn't allow the sun to come in the windows in the summer and only in the winter. I have deciduous trees that also block the sun out once they get leaves.
I am big into being a minimalist so I don't have to do anything to keep my house warm or cool.
It is run by a computer that opens windows and vents in the summer and turns on the whole house fan to cool it at night. In the morning it turns off and shuts the windows and vents.
My hydronic cooling is nice and I rarely have to have the central AC on.
