Solar panel

Abstract

A solar panel comprising a plurality of elongated and flat pipe elements having a first end, a second end and at least one longitudinal and through pipe channel for a heat carrying liquid, wherein the pipe channels are arranged with a height (H) up to 10 mm. the pipe elements are connected to opposite and elongated edge elements. The edge elements are arranged with a longitudinal channel for the heat carrying liquid, wherein the channels in the edge elements are connected to the pipe channels and extend in a direction perpendicular to the pipe channels. The pipe elements are formed with an aperture on opposite sides of at least one pipe channel, and stop devices are connected to the edge elements at selected apertures and extend into the channels of the edge elements to block the channels and guide the heat carrying liquid between the pipe channels.

1 . A solar panel comprising a plurality of elongated and flat pipe elements having a first end, a second end and at least one longitudinal and through pipe channel for a heat carrying liquid, wherein the pipe channels are arranged with a height (H) up to 10 mm, wherein
 the first end of the pipe elements are connected to a first edge element, and the second end of the pipe elements are connected to an opposite second edge element,   the first and second edge elements are elongated and arranged with a longitudinal channel for the heat carrying liquid, wherein the channels in the first and second edge elements are connected to the pipe channels and extend in a direction perpendicular to the pipe channels,   the pipe elements on opposite sides of at least one pipe channel are formed with an aperture, and   stop devices are connected to the pipe elements at selected apertures, wherein the stop devices extend into the channels of the edge elements to block the channels and guide the heat carrying liquid between the pipe channels.   
     
     
         2 .
