Production and quality control
--Current measurement under STC to avoid module mismatches
--Hot spot resistance testing of every single cell via the reverse current characteristic
--Across-the-board soft handling during production to avoid microfissures and reduce breakage rates during onward processing
--High-quality, homogeneous appearance thanks to Polycrystalline material

Electrical Properties
--Very good long-term electrical stability through crystalline silicon technology
--Excellent low light behaviour thanks to parallel resistance checks on every cell
--Narrowest worldwide current classes
--Classification into very narrow current classes
