United States/Solar Fans: Solar Attic Exhaust Fans/SunnyRetroFit Spec Sheet (.pdf) General Characteristics of Solar Fan, SunnyRetroFit . SunnyRetroFit solar fans are a perfect replacement for Roof Wind Turbines that frequently stop working due to corrosion. The SunnyRetroFit does not need to rotate to provide excellent ventilation. Instead, it exhausts heat using solar and wind energy. It also works passively through the Venturi effect, which occurs when the wind blows against the exterior grilles. As a result, this creates an updraft that allows air to flow freely in and out of the vent. The vertical vents expel air continuously and prevent the entry of rain and snow. The vertical vents also keep bugs and animals out, allowing for optimal airflow. Plus, the round design is aerodynamic to withstand wind speeds up to 200 mph. The SunnyRetroFit removes hot air in summer and moisture from the attic in winter to provide optimal ventilation. The Retrofit Vent header will fit over an exi
