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
Enlarge Image

This PV system is composed of polycrystalline PV modules and is one of two arrays of this type being evaluated on the pavilion. Polycrystalline modules are widely used in the solar industry and have similar performance to monocrystalline arrays.

System Ratings

  • AC output: 2.0 kW
  • PV array: 2.115 kW
  • PV module: 235 W x 9 modules
