Participants help to eliminate nontariff trade barriers. Participation keeps one on the cutting edge of current technology and market trends. This paper describes the organization of Technical Committee 82, (TC-82) Photovoltaics, of the International Electrotechnical Commission (IEC) and its various working groups that write standards for the international photovoltaic industry. 1. Objectives The objective of the TC-82 Secretariat is to effectively manage the activities of the several Working Groups (WG) of the Committee. This paper delineates the efforts that have resulted in published standards and lists those standards that are in process of being written. 2. The IEC Mission The International Electrotechnical Commission (IEC) is the leading global organization that prepares and publishes international standards for all electrical, electronic and related technologies. 3. TC-82 PV standards have been trailblazing other distributed generation standards. Chairman of TC 82 is Dr. Heinz Ossenbrink, JRC, Ispra, Italy; Howard O. Barikmo is the Secretary, Sunset Technology, Scottsdale, Arizona. The working groups of TC-82 are: WG1: Glossary (Convenor: Hidenori Shimizu, Japan) Task: To prepare a glossary. WG2: Modules, non-concentrating (Convenor: Dr. John Wohlgemuth, USA) Task: To develop international standards for non-concentrating, terrestrial photovoltaic modules. WG3: Systems (Convenr: Dr. Markus Real, Switzerland) Task: To give general instructions for the photovoltaic system design, construction and maintenance. WG6: Balance-of-system components (Convenor: Mr. Chuck Whitaker, USA) Task: To develop international standards for balance-of-system components for PV systems. WG 7: Concentrator modules (Convenor: Dr. Robert McConnell, USA) Task: To develop international standards for photovoltaic concentrators and receivers.
