Due to the project and semester schedules, we were not able to test the designs until November. The weather during November in Iowa can get pretty chilly, but these are the conditions under which the solar heater would actually be used. This photo shows the conditions of one of our final testing days.

Despite the chilly November weather and cloudy skies the solar heater was able to produce very warm output temperatures. (80.6 degrees Fahrenheit)

And these output temperatures continued to rise throughout testing. (110.0 degrees Fahrenheit)

This graph provides a summary of testing data for three testing sessions. Our team was very happy with these results and the maximum output temperature achieved exceeded everyone's expectations.

Our Design Expo poster summarizes an entire semester's worth of work. It includes customer requirements, specifications and benchmarking metrics, an engineering model, morphological charts for brainstorming, profitability analysis and final design results.
