The Treasure Coast Soaring Club will soon have a new house thermal. Florida Power And Light is in the process of building a 400 acre solar power plant within 3/4 mile from our airport. Heat from this type of farm should make for a great house thermal. Anyone out there with experience flying over solar farms? Thanks, Bob

I think that this would depend on several factors specific to your location.. Two being: 1)intensity of solar radiation 2)Surface air temperature in the adjacent area.

Try it and let us know.
