The CPV community has agreed to have both indoor and outdoor power ratings at the module level. The indoor rating provides a repeatable measure of module performance as it leaves the factory line while the outdoor rating provides a measure of true performance under real world conditions. The challenge with an outdoor rating is that the spectrum, temperature, wind speed, etc are constantly in fluxand therefore the resulting power rating varies from day to day and month to month. This work examines different methodologies for determining the outdoor power rating with the goal of minimizing variation even if data are collected under changing meteorological conditions.
