The certification of equipment, either nationally or internationally, is essential to ensure the smooth operation and durability of a photovoltaic system. For example, the certification chosen could be the one provided by the International Electrotechnical Commission (IEC), a global organization that prepares and publishes international standards for electrical technology, electronics and the like. In Brazil, the main certification agency in the area is the INMETRO.

Below are some INMETRO links that can be useful if you are interested in the subject of certification and labeling:
