Due to space restrictions, shading concerns, and inherited materials available to us, different layouts have been proposed for the solar array providing power to the HQ.

One constraint we have to work with is that all of the racking from the CRETE House is specifically designed for flat roofs. The only flat roof at Tyson is on a section of the LLC. Due to its size, not all 30 panels would fit on the roof. While we could not put all panels on the roof, we originally proposed to put some on the ground, as a contact at EFS Energy had a spare ground mount racking system that he offered to donate to the project. However, this design proved to be difficult to implement due to existing utility infrastructure and the cost and power loss associated with long conduit runs from each of the two separate arrays. To solve this problem, we first inquired with Dynoraxx and verified that the roof racking system could also be used to mount panels on the ground. This allowed us to minimize installation cost and complexity by arranging all 30 panels on the ground with the Dynoraxx racking in a field adjacent to the HQ. This strategy would also allow us to avoid existing utility lines and connect all of the panels as one array on a single inverter, leaving Tyson with the SolarEdge 3000H inverter to use for future projects or sell for profit.

The Dynoraxx racking is fixed at a 10° tilt angle, as shown in below. The panels will be oriented due south (azimuth angle of 0°) in order to maximize the amount of energy a panel can absorb throughout the day with the given tilt.

It is common for ground-mount systems to have a tilt angle of at least 20° in order to receive more solar irradiance at a lower mounting height. Tyson is planning to grade the ground underneath the array with a rock overlay at a 30° pitch. This slanted surface is expected to give an additional 10° of tilt to the panels relative to the surrounding field. The rock overlay will also prevent vegetation from growing up around the panels and blocking them from sunlight.
