Abstract

The invention refers to a solar testing device (11) for testing a solar module (6). The solar testing device (11) comprises a test area (12) for the solar module (6) to be tested, a light emitting area (16) comprising an array of LED-modules (17, 17A) arranged opposite to the test area (12) and arranged in a pitch (P) to each other. Further the solar testing device (11) comprises sidewall mirrors (21) extending in the direction from the light emitting area (16) to the test area (12). Guides (26) are provided having each an abutting surface (27) for supporting the solar module (6) whereby the abutting surfaces (27) of the guides (26) lie in the plane (A) of the test area (12).
