Guidelines for PV Power Measurement in Industry

Precise and reliable power measurements are essential to the PV industry and to investors. These guidelines present current best-practices for determination of maximum output power at standard test conditions (as opposed to the operating conditions). Particular attention is given to emerging technologies, such as high efficiency silicon and thin-film, which have high potential but also require adaptations of the measurement procedures already standardised for crystalline silicon devices. The guidelines have been compiled by the members of the PERFORMANCE Integrated Project and represent the culmination of 4 years work, including round robin testing, reviews and surveys, as well as the partner organisations extensive knowledge in this field.
