A photovoltaic system and a flexible bracket thereof. The flexible bracket comprises includes: at least two support members spaced in a first direction, wherein component cables and stabilizing cables are mounted between two adjacent support members in the first direction, and the component cables form a bearing surface; joint members connected to both the stabilizing cables and the component cables; and semi-rigid inverted-arch cables, wherein a first end of each semi-rigid inverted-arch cable is provided with a rigid portion connected to the joint member, and a second end of each semi-rigid inverted-arch cable is connected to the support member.

A solar energy system with a plurality of solar panels arranged in a row, wherein there is an innermost and an outermost solar panel, and at least one holding element oriented in the longitudinal direction of the solar energy system, on which the solar panels are held one behind the other and along which the solar panels can be moved by an engagement means from an extended operating position into a retracted protective position and vice versa, wherein adjacent solar panels are connected to one another in an articulated manner, so that a pushing or pulling force can be transmitted from one solar panel to an adjacent solar panel. The outermost and innermost solar panels are pressed against each other in the protective position by a mechanical force, forming a stable package of solar panels that enables the solar panels to protect themselves from the weather.

Exemplary embodiments described herein may include lightweight, low stow volume solar concentrator.
