The US Navy has awarded a $400,000 architectural and engineering contract to Honolulu-based SSFM International for photovoltaic power systems at facilities on the island. The PV systems will be mounted on the roofs of five large buildings at Pearl Harbor and 10 small buildings at the Pacific Missile Range Facility on Kaua’i, according to Naval Facilities Engineering Command Hawaii.

Design documents are required for photovoltaic systems that will produce a combined 2.2 MW of continuous power during peak daylight hours in its first year, the Navy said, which is using federal stimulus funds to have the work done. The output is equal to about 5% of the Navy’s energy consumption on O’ahu.

During its 20-year service life, the system is expected to retain at least 80% of its first year output.
