PROJECT SPECIFICATIONS FOR
SOLAR PHOTOVOLTAIC SYSTEM
AT LINCOLN MIDDLE SCHOOL

Performance:
Based upon Alameda Power & Telecom experience with a four-kW solar PV system, the LMS one-kW solar PV array is expected to produce 1,600 to 1,750 kWh per year. The solar PV awning covers the computer lab window area to offer a secondary shading benefit. Installation: The system is grid-tied, uses no batteries, and is mounted on racks in an awning configuration.

Location:
The system is located on the southwest wall of the LMS Arts/Science Building for maximum sunshine exposure and near the entrance of the school to promote community interest and discussion.

Photovoltaic System Specifications:

• 20 Siemens SM55 PV Modules,
• Advanced Energy GC1000 Inverter
• Advanced Energy AM100 Data Monitor software
• System Rating: 1,060 Watts (DC)

Data Analysis:
A data monitor (AM100 for data collection) is integral to the inverter and mounted on the wall below the solar PV array. A local PC in the LMS Science class will store the data from the AM100 data monitor. Dial-type and digital utility kWh meters (2 socket box) will be installed below the array on the exterior of the building so that students and visitors can check the kWh produced by the system.

Rack System:

• Side-wall awning configuration
• 35-degree tilt angle

Structural Attachment:
Two rows of galvanized Unistrut attach to the exterior wall of the science classroom. The solar PV rack mount then is attached to the Unistrut.
