A solar energy collecting panel includes a pair of elongated spaced apart tubular fluid headers formed of heat conductive material and a plurality of elongated hollow tubular panel elements or risers formed of heat conductive material extended between the headers. The panel elements have an outer wall adapted to face and absorb solar radiation and transfer the heat directly into fluid passing through the tubular passages of the risers which are arranged in edge to edge, side by side relation with opposite ends of the risers connected in direct fluid communication with a fluid passage in the headers through openings in a wall section thereof. The panels are especially adapted for interconnection together in an array and the headers in the panels are formed with a perforated inner wall dividing the fluid flow into a pair of passages; one passage for directing some of the fluid between the headers and the risers and the other passage acting as a plenum chamber or conduit for passing the fluid to the next adjacent panel.
