Grid-Tied Solar Power System
Municipal Case Study
Municipal Complex Loma Linda, CA
The 267kW solar power system provides more than 430 MWh of electricity annually—enough to power 35 homes. The Loma Linda solar power system includes four independent systems generating energy for the Civic Center, Fire Station, Library and Senior Center. The 1600 solar panels installed on buildings and carports are inconspicuous but still visible to the general public. The system’s reloaded performance is by an advanced status monitoring system that transforms raw energy data into a dynamic dashboard view. This interface provides live and historical views of the energy being produced, consumed and returned to the grid. The solar system reduces thousands of lbs of carbon dioxide emissions annually that would have been produced by coal or gas fired power plants. Gas emissions from coal or gas fired power plants can lead to smog, acid rain, haze and ultimately increase the risk of climate change.
System Specifications System Power: 267kW Number of Independent Systems: 4 PV Array: (1600) Sharp NE-17OU1 modules (170W, 24Vdc) System Maintenance: Once Every Month (compare kWh production, check inverter status, and arrays for damage and excessive soiling) Once Every Six Months (Clean Inverter) Once Every Year (Check electrical connections, PV module clamps and fasteners, PV cables and grounds) • Module cleaning improves performance up to 20% • 5 to 6 year payback Status Monitoring: • Creates a user friendly interface • Transforms raw data into understandable numbers and graphics • Provides live and historic system performance • Displays the amount of energy produced, consumed and returned to the grid
