PV Watts Viewer

NREL’s PVWattsTM calculator determines the energy production and cost savings of grid-connected photovoltaic (PV) energy systems throughout the world. It allows homeowners, installers, manufacturers, and researchers to easily develop estimates of the performance of hypothetical PV installations.

The PVWatts calculator works by creating hour-by-hour performance simulations that provide estimated monthly and annual energy production in kilowatts and energy value. Users can select a location and choose to use default values or their own system parameters for size, electric cost, array type, tilt angle, and azimuth angle. In addition, the PVWatts calculator can provide hourly performance data for the selected location.

Unirac Toolbelt


Features in the Unirac Toolbelt include:

  • The True South Compass, which enables you to determine how close to true south an array is pointed. The U-clinometer+ (U-clinometer 2.0), which enables you to determine the pitch and angle of any surface. You can also zero out multiple measurements to eliminate the angle of the roof vs. the angle of the array.
  • The QR Code Reader, which allows you to scan any QR Code and send or save the results.
  • The Theodolite, an augmented reality application which uses your device’s camera to determine a roof angle, height, altitude, latitude, longitude, and azimuth…all from ground level, without having to get on the roof!
  • One-click access to, Unirac Technical Support, and the Unirac Configurators.
