A brief description of the on-site renewable electricity generating facilities/devices:

SOU currently has SOU has 11 solar arrays on campus, totaling 515 kW of solar capacity. SOU's first solar array was installed on the Hannon Library in 2000. The 6kw solar array consists of 24 solar panels. In January 2019, SOU expanded on this system, adding an additional 55.65 kW of solar to the site. In the last 3 years, an additional 5 arrays have been added and funded through private investors, grants, the student body, and the University Administration. There are also now 3 net-zero buildings on campus. Further information can be found at https://news.sou.edu/2021/09/solar-arrays-pop-up-at-the-farm-at-sou/

A brief description of the clean and renewable stationary fuels:

SOU's Dining Hall and McLoughlin Residence Hall each have solar hot water systems installed to augment the natural gas domestic water heating. The system on McLoughlin Hall consists of an array of 16 flat plate solar collectors mounted on the roof, facing due south with a tilt of approximately 15 degrees from horizontal. Each solar collector is 48"x122". The total solar collector absorber area is 597.3 square feet. The efficiency of the collectors is 60.7%. The collectors are piped together on a glycol loop piped to a heat exchanger. The system has two 500 gallon solar preheat storage tanks.

The solar hot water system on the Dining Hall consists of an array of 8 flat plate solar collectors mounted on the roof, facing due south with a tilt of approximately 15 degrees from horizontal. Each solar collector is 48"x122". The total solar collector absorber area is 321.2 square feet. Efficiency of the collectors is 66.2%. The collectors are piped together on a glycol loop piped to a heat exchanger.
