Current Field Sites - 3kW Solar ORC Demonstrations
- Pilot Health Clinic - Pilot Health Clinic is located at Matjotjo Village in the Berea District of Lesotho, approximately 45-minutes' drive from Maseru. Pilot Clinic typically serves 50-80 patients each day and has a permanent live-in staff of 2-3 nurses (although it is closed through late 2013 for renovations of the clinic buildings). The STG system at Pilot Clinic is sized to provide 18-24kW-hr of electricity, along with 200-300 gallons of hot water, per day. These resources will allow nurses to extend clinic working hours and improve services to patients, as well as improve the quality of life for live-in staff - thus hopefully improving staff retention.
- Eckerd College - STG has established a research and development platform at Eckerd College in St. Petersburg, Florida to support ongoing upgrades and improvements to solar ORC technology. In addition to long term performance evaluation, STG is optimizing autonomous control strategies and testing new high efficiency expanders for the ORC at the Eckerd test facility. The solar array consists of 20 SopoNova collectors donated by Sopogy, Inc. while the ORC was custom built by STG.
Past Field Sites - 1kW Solar ORC Prototypes
- Bethel High-School - Bethel High School (BHS) is a major rural high school, drawing students from many villages and towns in the Phamong region of Lesotho. They run a diesel generator on fuel subsidized by the Lesotho Ministry of Education to power a small computer lab for their students for approximately four hours each day. Most students are housed in dormitories at the high school with little access to hot water, even during winters where temperatures drop significantly below freezing. The system was installed in 2007 at BHS located near the girls' dormitory to provide hot water to their bathing facilities and was disassembled in late 2008.
- Village of Ha Teboho - Ha Teboho is a small village near to Bethel, located just north of the Senqu River. The system installed at Ha Teboho was funded by the World Bank Devlopment Marketplace Grant, and was centrally located approximately 10m from the community water tap to provide on-demand hot water for the community to share. Unfortunately this system had to be dismantled in 2009 due to thefts of system components.
