Photovoltaic panel capacity testing specifications and requirements

What is PV capacity test & modeled energy test?

The purpose of the PV Capacity Test and modeled energy test is to verify that the integrated system formed from all components of the PV Project has a production capacity that achieves the Guaranteed Capacity and the Guaranteed modeled AEP under measured weather conditions that occur when each PV Capacity Test is conducted.

Where can I find a copy of a photovoltaic test specification?

Outlined in this document are the test conditions related to our test chambers. For more information on IEC, UL or ASTM standards or to purchase a copy of the full specification, visit the following web sites, , or The most common photovoltaic test specifications along with our Environmental Testing Guide.

What is a standard test for photovoltaic non-concentrator system performance?

One popular test is ASTM 2848-13 “Standard Test Method for Reporting Photovoltaic Non-Concentrator System Performance”. The goal of this test is to compare the ratio of a modeled system vs the actual system performance, and the system should perform the same as the model, minus some uncertainty.

When should a PV capacity test plan be submitted?

No less than 45 days prior to the first day of the PV Capacity Test Measurement Period, a proposed PV Capacity Test Plan shall be submitted to the Owners' Rep-resentative by the Contractor for Owners' Representative review and comment.
