Abstract
A solar boiler of improved energy efficiency that includes a solar panel for receiving solar energy and converting a liquid to steam and a highly accurate tracking system to maintain the panel substantially perpendicular to the sun. The panel includes a plurality of heat transfer liquid carrying tubes having a highly absorptive coating over areas receiving solar energy and high efficiency insulating material over remaining surface areas. An extruded compound concentrating cylindrical lens is positioned over each tube to concentrate received solar energy along a narrow linear energy receiving area. Each panel is mounted for rotation and tilting on a simple, sturdy base. Each panel is substantially closed but includes openings designed so that some air flow through the panel is permitted to prevent excessive heat within the panel while preventing entry of moisture. A tracking system capable of tracking with accuracy of substantially one-half degree or better is provided, utilizing an improved sensor and electronic circuit. A device utilizing the steam produced in the panel, such as a fluid driven engine powered electrical generator, may be positioned closely adjacent to the tubes to receive steam from the tubes.
