Naval Air Weapons Station

Seal Beach, Ca

Stronghold Engineering, Inc. served as the prime contractor for this $2.3M fast-track design-build project to install Solar Photovoltaic Power Systems (SPVPS) for two (2) buildings at the Naval Air Weapons Station in Seal Beach, CA. This project was part of the American recovery and Reinvestment Act (ARRA) of 2009, which aims to reduce carbon footprints through renewable energy. The SPVPS was installed on the roofs of each building which included demolition and replacement of each roof system. Each SPVPS supplies power to the building and feeds energy back into the power grid if/when there is an excess of electricity produced. The SPVPS consists 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 1,246 multi-crystalline photovoltaic modules were installed to generate more than 269,000 kWH annually. The modules are 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.


“The contractor’s design exceed the RFP requirements in several aspects that significantly benefited the government…All materials and workmanship were of the highest quality…The contractor’s field management team including the superintendent and quality control manager were exceptionally professional, knowledgeable, courteous and conscientious, easily one of the best field teams the government has worked with.”
