Efficiency and Solar Flux vs Delta T

Efficiency and Solar Flux vs Delta T

An Alternate way to look at our data, showing the correlation between efficiency, solar flux, and delta T.

Efficiency comparison

public/Eff_comparison

The SRCC categorizes our panel with the orange efficiency curve in the image above. The blue line represents the efficiency trend-line curve of our data.

The efficiency curve comparison shows that our data does not exactly match the SRCC expected performance. However the optical efficiency (y-intercept) is very close between the two curves.

Full test results.

Feasibility

A heat analysis was preformed on the hot tub system.

Assumptions:

The analysis concluded that the solar collector would be able to provide enough energy to maintain the temperature of the hot tub during periods of high solar flux through all seasons except winter, and partly during periods of medium to low flux through the seasons of fall to spring. 0 W gains can occur due the efficiency of the collector being less than zero, which in practicality would result in the collector not running.

public/cost

Above is our full cost tracking spreadsheet for all items purchased with their actual cost. Rather than just show the cost that was actually paid for the items, the team thought it best to include both the estimated cost of the items (which were based on online research) as well as the true price paid. We felt this was important as a guide for other groups wanting to complete this project independently. The prices found in the color coded BOM (top) represent values found online and were independent of any local pricing, sale pricing, shipping costs, or other discounts given to the team as a student project. Discrepancies between the two exist due primarily to variance between online and store pricing, as well as shipping costs. This will help eliminate the argument that special pricing was given and paints a clearer picture that a project of this nature is truly affordable. Also, the color coded BOM is more complete, in that it details all required materials needed to complete this project. Whereas the second BOM is more of a receipt used by the team & MSD office to track our actual spending.
