What are the large, black rectangles found on Florida roofs? They're not solar panels, but something else?
What are the large, black rectangles found on Florida roofs? They're not solar panels, but something else?
I live in central Florida, and I happen to see these things on many houses. There usually 5 or 10 feet by 10 to 30 feet in size. I know they are not solar panels because those devices have a reflective surface of sorts. So what are they and is there purpose?
Also, what do they cost to buy and install (if you happen to know)?
These are solar panels for swimming pools. I have some on my house and will increase the pool temp 10-15 degrees. They are cheap to purchase and easy to work with. Look at link to see if this is what you are talking about.
