The sun's heat passes through the windows and gets absorbed by dense materials like brick, stone, concrete, or rammed earth that will store the heat and release it later. Also called "Thermal Mass", these heavy materials serve to keep the house from overheating when the sun shines and later release heat when the sun is not shining.
The single solar panel provides dc power to assist the fan that moves air across the outdoor coil, a key part of any home comfort system. The fan has an ac motor for normal operation and a special dc motor that assists whenever sufficient sunlight is available.
It is clear the PV industry has done a much better job communicating solar electric. I understand the various industry associations recognize this confusion. I hope we see more of the consumer marketing aimed not just at solar thermal but explaining the differences and how a dual energy system is another good option to leverage their solar investment.
