PMC is the sole US agency for the Global Approval Program for Photovoltaics and the only US PV testing and certification program meeting the requirements for international reciprocity. This means that a product certified to IEC standards in a PowerMark-accredited laboratory is also eligible for certification marks administered by international laboratories. PowerMark’s international reciprocity eliminates the need for conforming to multiple qualification testing programs.
PowerMark currently offers the following certifications:
Qualification tests are conducted on PV modules in accordance with IEC61215 or IEC61646. These tests provide simulated exposure testing to evaluate the quality and reliability of the PV module design and construction. Two laboratories in the US and at least three in Europe are currently PowerMark qualified for performing these tests.
Module output power and temperature coefficients are measured using standardized procedure to verify the manufacturer’s rating. Module output power may be certified alone or as part of Qualification and Type approval.
Packaged systems and component tests are conducted to verify the manufactures performance ratings using IEC standards. If there are no IEC standards for a particular product, recognized industry or national standards may be used.
In the future, PowerMark will be adding other components (such as inverters and charge controllers) to the list of equipment certifications.
In order to apply for PowerMark certification, the manufacturer of a product must have established an ISO 9000 certified and audited quality system.
Continued PMC certification requires a commitment to maintain the manufacturer's quality systems and to retest when changes are made that may affect quality.
