Problem Definition[edit]

Demonstrate the feasibility of Solar Roadway™ panels being implemented as part of the walkways for the soon to be constructed Idaho Central Credit Union Arena.


The University of Idaho is currently preparing to expand on campus next to the Kibbie Dome. The building that will be erected is the Idaho Central Credit Union Arena, which will occupy the current gravel lot adjacent to the enclosed football field on the northern side. While the project will begin groundbreaking following its secured funding for construction, time remains where additions may be suggested to those directing the project. The senior design team would like to simulate conditions in which the use of solar panels as designed by SolarRoadways could be implemented within the construction of the building and be utilized in the final design. The team is currently able to immediately acquire two panels for the use of experiments in which they would demonstrate the added benefits of the panel’s implementation. The students and their investigation would seek to prove that multiple instances of their panels would prove beneficial for the university within a proposed time frame.


  • Understanding and implementing detailed controls which allow for the manipulation of the LED displays for each panel
  • Determining the optimization and usage of the heating elements within each panel
  • Validating the efficiency of the PV panels to that of other PV panels located on campus


Project Specifications
Design Area Specification
Software (User Interface)
  • The software must use time division multiplexing to display an image
  • The interface must display a smaller version of the image being displayed on the panels
  • The interface must be user friendly

Design Considerations[edit]

Design Considerations
Design Area Test
SR™ LED Control
  • Attempt pre-determined image patterns using the SR™ software
  • Attempt custom image patterns using the SR™ software
UIdaho LED Control
  • Create and design original software that will control LED output. Use time division multiplexing to display an image
Operating Conditions
  • Determine the output current and voltage of the panels through the previous Senior Design Team's test conditions
Heating Element Optimization
  • Measure power generated at varying temperatures to determine best temperature to heat that will melt snow and ice
Feasibility Analysis
  • Compare the efficiency of the SR™ panels between the Senior Design Teams
UIdaho Validation
  • Acquire the PV generation data generated by the UIdaho solar panels. Measure against the time in which both senior design teams also generated PV data

Project Learning[edit]

  • Gain a better understanding of solar panel integration an already existing grid
  • Gain a better understanding of semiconductor physics within a solar panel
  • Gain a better understanding of how the angle of a install solar panel effects efficiency
  • Gain a better understanding of implementing time division multiplexing to transmit multiple digital signals over a common channel split into segments with a short time duration
