With the development of new energy technology, photovoltaic modules are increasingly used in various products, which makes the performance testing of photovoltaic modules particularly important. Millennial Solar will bring you the relevant content of IEC61215 today. Solar photovoltaic modules are the core part of the solar power generation system and the most important part of the solar power generation system. Its function is to convert solar energy into electrical energy, or store it, or promote load work.

About IEC

The International Electrotechnical Commission (IEC) was established in 1906. It is the earliest international electrotechnical standardization organization in the world and is responsible for international standardization work in the fields of electrical engineering and electronic engineering. The goals of the committee are: to effectively meet the needs of the global market; to ensure priority and maximum use of its standards and conformity assessment programs worldwide; to assess and improve the quality of products and services covered by its standards; create conditions for the joint use of complex systems; increase the effectiveness of industrialization processes; improve human health and safety; and protect the environment.

IEC61215  

Since the first release of the "IEC 61215 Series Standards" in 1993, it has become the basic evaluation standard for photovoltaic module design identification and finalization, and its development trends have also attracted much attention in the industry. The current series standards were released in 2016 and are already lagging behind and cannot meet the current needs of the photovoltaic market. Therefore, in response to emerging photovoltaic module technology and testing controversies, IEC has made a series of revisions to the 61215 series of standards, which will be officially released in March 2021.

Standard testing process

The proportion of photovoltaic power generation in global electricity supply is increasing rapidly. High cost pressure and short innovation cycles make the photovoltaic module market dynamic. More efficient and cheaper products are constantly emerging, including solar cells, backsheets and packaging materials. The quality assurance of photovoltaic modules has attracted more and more attention from investors and manufacturers.

Wet Leakage Current Tester can test the insulation performance of photovoltaic modules under humid working conditions and detect whether moisture from rain, fog, dew or melted snow enters the working part of the internal circuit of the module, causing corrosion, leakage, and non-safety accidents. Comply with the IEC61215 standard MQT15 clause and IEC61730 MST17 clause.
