[Dad was my hero]

I had a “system” installed. First was solar assisted heating/cooling that uses solar to super heat the coolant for the heat pump. In FL this greatly reduced my cooling costs. At the same time I had solar hot water installed. Between the two of them I cut my electric bill by about 75%. Then added the last section which was PV solar - a 5kW system (20 panels). All qualified for a 30% federal tax credit. The tax credit made the payback at the current electricity rates a little over 7 years. If (which isn’t really if but more when) electricity rates increase the payback will shorten. Reduced my electric bills from over $300 a month to about $25 per month, half of which is the charge for the meter and hookup to the grid.

How does adding heat to a cooling system help in any way?
