IEC 61724-1: Conforming and Exceeding the Standard

2018 looks to be another booming year for installed solar power sites around the world. In addition to traditional major markets in Europe, China, and the United States, emerging countries in the Americas and Middle East look to big movers as the install larger projects. As solar power plants have increased in size and numbers, new standards were needed to help a fast-changing industry. During 2017, the International Electrotechnical Commission (IEC) released a new standard, 61724-1, Photovoltaic system performance – Part 1: Monitoring. The standard provides guidance as to the measurements needed to attain a specific level or classification of accuracy. The standard provides all the details as to when and how to measure the critical environmental parameters. It also provides information on the differences in requirements based on installation size and power generating technologies and methods. Only considering the most common form of power generation, non-concentrating photovoltaic (PV) installations, the standard provides 3 classifications or levels of accuracy.

This new standard will provide crucial guidance to various stake holders as to what measurements are needed. Couple this information with EKO’s 90 years of intense development and you have the right combination to make certain any PV site is monitoring at the optimal level. For the highest level of performance, EKO recommends using the MS-80 series pyranometer with the MV-01 heated ventilator. The MS-80 surpasses the requirements of ISO 9060 and sets a new bar for pyranometer performance. While the IEC standard calls for recalibration annually, the MS-80 has a 5 year recommended recalibration interval. The MS-80 has been designed such that the user does not need to change the desiccant. As for performance, the MS-80 has fastest response time of any secondary standard on the market. It also is immune to thermal offsets, monitoring with the MS-80 provides greater confidence in measurement accuracy as well as the ability to detect fast changes in irradiance with passing clouds.

With a global presence and a persistent drive to improve solar radiation measurements, EKO stands ready to help the solar energy industry with any project, regardless of size or complexity. Please contact your local or regional EKO Instruments office.
