The object of the invention is a mobile solar device intended for the acquisition and conversion of electrical energy from solar energy and for storing it. In particular, a mobile solar device intended for supplying energy in areas difficult to access or crisis areas.

There are solutions for mobile solar devices in which substantially flat modules with solar panels are integrated with the control system and an energy battery with a substantially rectangular container design. For the operation mode, the solar panels are located outside the container and positioned angularly to the sun.

Document US 7,230,819 B2 discloses a mobile solar device in which modules with the solar panel are located on the upper wall and at least one side wall of the container. Each solar panel cooperates with an angular control system attached to the corresponding wall on which the panel is located. In operation the solar panels are angularly deflected from the container walls and set towards the sun.

Document US 2010/0206354 A1A discloses a mobile power system in which modules with solar panels are located inside the container. During operation complex modules with solar panels are extended from the front wall of the container and set towards the sun.

A more complex design of the mobile solar device is an object of the application EP 2 822 178 Al. In this solution, modules with the solar panels are located inside the container as well as on its upper wall and at least one side wall. Additionally, the panels located on the walls of the container are covered from the outside with boards e.g. wooden or cork, which further protect the panels not located inside the container against the influence of unfavourable external factors or transport effects. On the front walls the container is provided with a door through which, during operation, the internal solar panels are pulled out of the container, slid and unfolded outwards angularly towards the sun. The outer panels are angularly deflected and the same as the interior panels set towards the sun.

The invention aims to provide an improved container design incorporating a mobile solar device for protecting solar panels against the adverse influence of environmental factors and transport and, at the same time, easier and faster assembly of the finished system for the operating mode.
