A modular panel for a solar boiler includes an inlet header, an outlet header, and a plurality of tubes fluidly connecting the inlet header to the outlet header. The tubes are substantially coplanar with one another forming a solar receiver surface and an opposed internal surface. The panel is modular in terms of height, width, number of tubes, and size of tubes, for improved handling of high heat flux and resultant thermally induced stresses.
