Stronghold Engineering, Inc. serves as the prime contractor for this $2.6M fast-track design-build project to install Solar Photovoltaic Power Systems (SPVPS) for three (3) buildings at the Naval Base in San Diego, CA. This project is part of the American recovery and Reinvestment Act (ARRA) of 2009, which aims to reduce carbon footprints through renewable energy. The 187kW SPVPS will be installed on the roofs of each building which will include demolition and replacement of each roof system. Each SPVPS will supply power to the building and feed energy back into the power grid if/when there is an excess of electricity produced. The SPVPS consist of multi-crystalline photovoltaic modules, inverters, a monitoring system, combiner boxes, a racking system, a mounting system, a housekeeping pad, sunshade and fence.

A total of 868 multi-crystalline photovoltaic modules were installed to generate more than 187,000 kWH annually. The modules were Sharp and were used in the design because of their high performance to cost ratio and their long standing track record and reputation for high quality and long life cycle
