Today at 11:00 am it was around 65 degrees in Fort Myers. My vehicle was parked at a job site with the windows closed for about one hour. When I got back to the vehicle, the car’s thermometer read 86 degrees inside!

When people ask me if solar pool heating or solar water heating works in the winter when it is cold outside, I always point to the hot car phenomenon. As long as solar radiotion is striking a surface, it has the potential to absorb solar energy. Since solar pool heating and solar water heating panels are designed to absorb solar radiation, the performance in winter is quite amazing!

Because we have such sunny weather in winter in Southwest Florida, solar collectors work great this time of year – the time of year that solar thermal technology is needed most!
