I. GENERAL

A. SCOPE OF WORK: This project includes the installation of six ground mounted photo voltaic solar arrays and all necessary equipment to tie into an existing back-up diesel generator system. Four arrays are composed of 15 Solon 230 watt PV modules each and two arrays are composed of 16 Astropower 110 watt PV modules each. The major components of the system will be Government furnished and are ready for installation. The Contractor is responsible to determine what additional parts and materials are needed to make a complete and workable system according to the plans and specifications. The project is located at the Hawaii Experimental Tropical Forest, Laupahoehoe Administrative Site, 36-645 Spencer Road, Laupahoehoe, HI 96764. All work shall be coordinated with the Contracting Officer’s Representative (COR).

B. GOVERNMENT FURNISHED INFORMATION AND MATERIALS: Government furnished materials include the PV panels, rack mounting system, inverters and charge controllers.
