NOVELTY - The arrangement (100) has a reflector (1) or mirror for reflecting sunlight. A reflector holder (15) holds the reflector, and is fixed to an edge (16) of the reflector by a fixing element (14). The fixing element comprises a spring element (141). The reflector is clamped by the fixing element, where the fixing element and the reflector are connected together by an elastomeric separator (17). The reflector is selected from a group consisting of a flat reflector and a cold/hot bent reflector with parabolic shaped permanent reflector bending.    USE - Sunlight reflecting arrangement for use in a solar collector assembly used an in power plant for converting solar energy into electrical energy (all claimed).    ADVANTAGE - The arrangement is inexpensive and reliable. The spring element makes the fixing element to be elastically deformable such that deformability of the spring element can be based on material of the spring element and on a structure of the spring element, so that an external load such as load caused by gust of wind, can be reduced, thus resulting in reduced mechanical stress within the reflector or within the sunlight reflecting arrangement, and hence increasing durability of the reflector of the arrangement. The arrangement is manufactured at low cost with reduced time. The arrangement allows dismantling and replacing of the reflector to be easily carried out in case of damage of the reflector such that the fixing element with the spring element can be re-used, so that special tools or machines for assembling or disassembling are eliminated, thus reducing maintenance cost of the arrangement. The arrangement reduces probability of damage of the reflector due to acceptable small movements. The reflector is less susceptible to the deformation, thus increasing optical accuracy of the arrangement.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing a sunlight reflecting arrangement.
