Shed Solar Ventilation Fan Project

Our shed (from Eastern Shed Company) gets full sun during the day. The temperature in the shed is normally 20˚ F warmer than the outside. We are located at 42 degrees North latitude. The shed dimensions are 10' x 18'.

The shed came with 3 small vents on each gable. I wanted to make use of the existing ventilation holes to keep it simple.

Amazon sells plenty of all-in-one DIY kits but I wanted to experiment on my own and possibly re-use components and/or change design plans later on.

I purchased 3 12V DC fans on Amazon and connected them to a DROK DC-to-DC Buck Converter to reduce the solar panel's Voltage and Amps to a number that won't burn out the fans...

Each fan is about 3.15" width and height and 1" deep.

The DROK DC-to-DC Buck Converter is unprotected and is a temporary setup until I can find a more suitable converter...

These fans are listed at 60CFM (cubic feet per minute). 3 of these produces 180 CFM which did not move enough air to sufficiently cool our shed. On the first day of testing at 60 degrees F outside temperature, the temperature in the shed was about 10 degrees cooler.
