IES was pleased to be selected as SDG&E's design, supply, build partner for the Center's new 120kw photovoltaic array. The installation also acts as an important educational tool featuring a real-time, interactive data acquisition display. IES worked closely with partners SDG&E's Sustainable Communities Program and Kyocera to make certain the system was affordable for the nonprofit Center.
We are pleased to report that system is currently performing above specs and was delivered on-time, on-budget and with zero change orders!
Specifications
- 120 kw array
- 684 Kyocera KC175GT polycrystaline modules
- 1 Satcon 100 kw inverter
- Sunlink flat roof mount with 10° tilt
U. S. Navy - Santa Cruz Island
Photovoltatic / Diesel Hybrid - Remote/Off-Grid
Santa Cruz Island is located about 25 miles off the coast of California. Most of the island is wilderness and owned by the National Park Service and The Nature Conservancy. The US Navy also operates a small facility with barracks and support infrastructure serving the entire island. Recently, IES completed a unique PV/diesel-hybrid project designed to provide clean, reliable electricity to this remote and environmentally sensitive location.

The system uses a large photovoltaic array which feeds into a sophisticated power tracking system that keeps a 2 Mw/h battery bank charged. Three diesel generators provide power for night use and extra capacity. The entire system senses loads, generation capacity and charge states -- delivering the required outputs where needed. IES delivered the project on-time, within budget, and with zero change orders.
