Testing a Hybrid Solar Panel UMass Lowell The optimal azimuth that the modules should be directed towards would be true south, since this is the direction that the northeastern United States that receives the most energy from the sun. The azimuth can be approximated by using Figure 1 , with the knowledge that Lowell, MA, is located at approximately 42.6334 o N. Figure 1: Azimuth of Solar Panel vs Latitude of Test Site, take latitude and follow it to as close to 100%, then read azimuth http://www.renewable-energy-concepts.com/solarenergy/solar-basics/orientation- azimuth-angle.html The angle (amount of tilt) that the solar collectors should be mounted at depends on the latitude of the test location. The optimal tilt angle can then be found using Table 1 . Testing a Hybrid Solar Panel 2 1/20/2024

This is shown in Figure 2. Figure 2: Azimuth and Tilt Angle of Solar Panels The thermocouples would be located on top of the solar panels, in a configuration such as shown in Figure 3. They would be divided evenly among each panel (15 each). Testing a Hybrid Solar Panel 3 1/20/2024
