Do solar attic fans work? Actual temperature test.

Have you ever asked yourself: do solar attic fans really work? I bought two of them from RemingtonSolar.com and did a real solar attic fan test and tested with temperature change. It was not super hot, but look for another video and I'll try it again when it's really hot. But I did seem to get the temperature down considerably within about an hour of the fans running on a warm (Texas) day. This was a good test to research solar attic fans. My two 25-watt solar fans brought the temperature down from 110 degrees to 101 degrees in about an hour, which is within range of the 10 degree ambient range outside. My soffit venting is good. I think solar attic fans, with proper soffit ventilation, can reduce attic temperatures.

I haven't seen many tests or real research data about solar attic fans. Do solar attic fans really work? I think the data here on a mildly hot day tells the story.
