Device and method for sunlight-based power generation

An energy generation device comprising

• a reflection panel presenting a reflecting surface,
• an energy generation module, and
• a holding structure holding the reflection panel and the energy generation module together,
• wherein the reflection panel is configured to filter an incident sunlight thereby letting a first portion of said sunlight pass through the reflection panel and reflecting a second portion of said sunlight,
• characterized in that said reflection panel is a single piece panel comprising a plurality of differently oriented adjacent reflective lamellas, wherein a position and an orientation of each lamella of said plurality of differently oriented adjacent reflective lamellas is based on a length and a tilt angle of the energy generation module, a distance between the lamella and the energy generation module, and a size and orientation angle of a neighbor lamella such that each lamella homogeneously focuses said second portion of incident light on a collecting surface of said energy generation module,
• wherein the holding structure connects the reflection panel to the energy generation module such that the reflection panel reflects light onto the energy generation module at a fixed angle.
