Combustion module having substantially uniform temperature

A hybrid solar system comprising:

• a concentrator for concentrating solar radiation:
• at least one combustion module that includes
• a body having a first end face and a second end face, the combustion module being arranged such that concentrated radiation illuminates one face of the body, and
• several combustion chambers formed in the body, and extending parallel to each other along a longitudinal direction between the first end face and the second end face of the body, a distance between the combustion chambers and/or dimensions of the combustion chambers being chosen so as to reduce a temperature gradient transversal to the combustion chambers, wherein
• the body comprises two lateral faces and first combustion chambers situated near to the lateral faces and second combustion chambers arranged between the first combustion chambers;
• a convertor for converting thermal energy into electricity on a face opposite to that illuminated by the concentrated solar radiation;
• and
• a controller for controlling combustion in the combustion module as a function of the concentrated solar radiation, wherein
• a distance between a pair of second combustion chambers is greater than a distance separating a first combustion chamber and a second combustion chamber.
