The SunRise Solar FB850FT 11 Watt Flat Base Solar Attic Fan with Thermostat is a unique, solar-powered vent fan that forcibly expels hot air, providing fresh and cool air to keep your attic from overheating. It also comes with a thermostat to help you determine the current room temperature.
The tough, weather-resistant advanced solar panels collect energy even in reduced light and poor weather conditions, and it delivers power directly from the sun to a highly efficient 12-volt DC motor inside the power vent to provide maximum cooling effect when it's needed most: in the middle of the day. These solar attic fans are powerful enough to protect an entire home. The Flat Base model is ideal for normal sloped shingle roofs.
The latest state-of-the-art circuitry captures sunlight even on overcast days. Totally weatherproof, our panels are designed for optimum efficiency and are hail, and extreme weather resistant.

Review of 30357
When its in sunlight, it is really throwing the CFM's, and you can't even hear it running, its motor is a very solid motor, almost like the industrial style ones, not a flimsy case one. Temp sensor seems to work great, air flow is great, even in lower light it moves a pretty good amount of air, way more then what the standard attic soffit / ridge venting gives you.
