Method to Improve PV System Performance Monitoring

Technology Overview

Within the solar energy industry, there is a general motto of "install it and forget it " for solar energy. This idea is largely derived from the research and reliability studies performed on the PV panels themselves but not the PV system as a whole (including inverters and other components). Other PV system components such as inverters contribute to a significant amount of power loss and the losses may vary based on different models of inverters. This technology relates to a method that can reduce measurement errors and achieve normalization among inverters used in PV systems in line with Class A of the updated IEC 61724-1 standard  With this method, the inverter-induced error can be reduced by up to 4.46%. The technology owner is looking for licensing partners to commercialize the test method.
