Solar roadways

“Solar Roadways”, located in Sandpoint, Idaho, is working towards manufacturing a modular system of specially engineered solar panels that can be walked and driven upon. The panels use LEDs to create signage without paint and heating elements to remove snow and ice accumulation. Our team is working closely with the staff here at the University of Idaho (U of I) and with this company to ensure the development of Solar Roadway panels that exceeds expectations and hopefully will be installed at the University of Idaho in the near future. We will be updating the information on this page monthly until it is finalized in December of 2018, where we will then hope to share the success of our project.

 	Solar Roadway (SR) Panel Circuit Diagram
 
 V1 represents Solar Roadway panel voltage
 Power rating of SR panel: 44 W
 Measured open circuit voltage: 22.3 V
 P_rated = (Voc^2)/R
 resistance is calculated to be around 11 ohms
 Resistors from BEL Power Lab – Modelled using LTspice
 	
Solar Roadway Panel I-V Characteristic Curve
 DC sweep of SR panel voltage V(n012) from 6 V to 23 V 
 Current across R1 is plotted
 Power is calculated by multiplying voltage by current

Objective
 Determine the total power produced from Solar Roadway panels during peak sunlight.
Location
 University of Idaho Steam Plant
Materials
 -One Solar Roadway (SR) panel
 -One Digilent board
 -One laptop with Diligent software included (data sample)
 -One fifty-Watt one ohm resistor
Steps for testing
 1)Place SR panel flat on UI Steam Plant near direct sunlight exposure.
 2)Connect SR panel to resistor.
 3)Connect Digilent board to laptop.
 4)Connect Vin pin to SR panel blue wire.
 5)Connect ground pin to SR panel white wire. 
 6)Connect voltmeter pin to resistors and measure voltage across resistor.
 7)Sample voltage across panel (�V�in) and voltage across resistor (Vr) using laptop and Digilent meter.
 8)Calculate current by subtracting voltage of Solar Roadway panel by the voltage across the resistors and divide that value by the resistance.
 9)Calculate power by multiplying voltage across resistor by the current across the resistor.
