Sussex County EOC
Overview
As part of a larger Energy Efficiency and Conservation Block Grant (EECBG), the 108.9 kW Sussex County Emergency Operations Center solar system was funded through the American Reinvestment and Recovery Act (ARRA) to reduce the operating costs of county facilities. Located within the Sussex County Airport complex, the EOC provides southern Delaware with 911 call response and emergency management services. The ground mounted solar array is constructed adjacent to the EOC facility and electrically interconnected via net-metering.
Engineering
Engineered for minimal site impact, the 108.9 kW solar system features the Schletter FS driven post mounting system, eliminating the need for concrete support footers. Designed for maximum efficiency and energy yield, the solar system utilizes eighteen individual SMA inverters providing a more granular maximum power point tracking architecture with less central points of failure.
In order to integrate with the existing diesel backup generator and UPS systems present within the EOC, the solar system was specially engineered to operate without the EOC losing any functionality of their existing systems. Additionally, the EOC can perform full load tests of the backup generator equipment, while the solar system will remain online sending all electricity generation to the utility grid for credit. The “Buy American” compliant project features (396) Suntech solar modules and (3) SMA Sunny Tower inverter banks.
Benefits
Designed for maximum yield and optimum use of the limited area available, the Sussex County EOC solar project reduces the operational costs of the county operated facility. Over a thirty year life, the solar system is expected to produce over 4.2 million kWh of electricity. Additionally, both the county and citizens can closely track the systems performance through a public web-based monitoring system and a lobby kiosk.
Note: The Sussex County Emergency Operation Center solar project was designed and constructed by Flexera, Inc. under the direction of Mr. Manlove during his tenure with the company. Mr. Manlove is the Professional Engineer of record for the project.
