2015 PV Solar Resource Workshop
Friday, February 27, 2015
Chairs: Manajit Sengupta and Cliff Hansen
This workshop revived the Solar Resource Workshop that NREL has hosted in previous years with a special emphasis on PV-specific issues. The workshop focused on how to best understand the solar resource available to PV plants and opportunities for the community to improve over the current state-of-the-art.
Assessment of the potential solar resource for a site often uses irradiance data derived from satellite data with some input from ground sensors. In contrast, ground-based measurements at the plant typically provide the basis for monitoring the performance of a PV plant. Some plants use thermopiles, while others use reference cells to monitor the available solar resource. Some organizations measure the performance ratio of the system relative to a cleaned sensor, and others only clean the sensor when the system is cleaned.

This event is part of the 2015 Photovoltaic Module Reliability Workshop, which is sponsored by the U.S. Department of Energy Solar Energy Technologies Office.
