5 2. PV Module 2.1 General Classification Are there several module types with an identical design, but with different power classifications? If so, please list all types in a separate document. Y N Sorting Do the modules have a "positive" sorting (no negative deviations with respect to rated power)? Uncertainty in rated power What is the absolute (measurement) uncertainty of the rated power values? Data sheet Detailed module data sheets are available for each of the named module types. (please attach) Type label A unique type label is available in each case. (please attach) Dimensions The module dimensions are: For crystalline silicone modules: Module length: 1600 mm ± 10%? Module width: 950 mm ± 15%? Module length: Module width: Ease of handling Can the module be managed and installed without additional lifting equipment? Weight Does the module weight more than 24 kg? Module weight:
