Performance Snapshot
Performance Snapshot

This panel may show a sampled measurement (e.g., power) and/or a cumulative measurement (e.g., energy generated).

When the sampled measurement is available, a gauge and trend chart will appear.

When the cumulative measurement is available, its value will be shown over the date range indicated.

Overview

The parking lot solar canopies are located on the east and west sides of the office building. During daytime hours, the power generated from these systems goes to the office building, offsetting power used by the EV charging stations.

Demonstration Value

Solar canopies offer protection from the weather along with providing a space-efficient way to mount solar systems.

System Ratings

  • AC output: 120 kW
  • PV array: 146 kW
  • PV module: 255 W x 448 modules and 305 W x 104 modules
