Abstract:

The objective of this project was to demonstrate an innovative hybrid electricthermal solar cogeneration system, document performance and cost advantages, and develop financing models and engineering tools to expedite transfer of the technology widely across DoD facilities. The demonstration project included the installation of systems at five separate buildings. The electricity and thermal energy delivered by these systems was measured for one year, and the systems continue to operate. Lifecycle cost analysis demonstrated that the systems offer a payback period of 5.1 years, one half to two thirds the payback time of photovoltaics PV or solar hot water SHW. The results of the project demonstrated the increased value of cogeneration, enabling accelerated and cost-effective compliance with the DoDs energy and environmental goals. Operation and maintenance requirements have been similar to PV or SHW and the systems continue to operate successfully.
