The ENHANCE project aimed to explore new test procedures and their measurement uncertainty, and to implement new equipment or adapting existing test facilities to new module structures with higher energy yields or higher esthetical value. The main objective was to perform the indoor characterization of selected test samples, to install those outdoor and monitor them for a full year. The rest of the project was focused on the development of new tests and procedures such as the electrical characterization of the bi-facial technology according to the IEC 60904-1-2 and the angle of incidence loss analysis as described in the standard IEC 61853-2. The implementation of the first procedure represents an important milestone for the laboratory due to the great expectation that the bi-facial technology is creating in the market. The incident angle test determines the fraction of irradiance available for conversion into electric current and it represents an important contribution when rating power and energy under non-standard test condition, especially in aesthetic modules where colors and textures might have a relevant impact.
