Systems and methods for concentrating and storing solar energy are provided. A solar energy receiver for use with the systems and methods may include a container for holding a solar absorption material, such as a phase change material, and a cooled cover disposed above the container for condensing and collecting vaporized phase change material collected along an underside of the cover.

An apparatus and method for connecting solar panels to a roof system surface. The solar panels can be formed flexible or non-flexible solar panels that are at least partially attached to a roofing surface by use of a fastener.

The enhanced oil recovery (EOR) system includes a solar tower that heats air, which is fed to an ion transport membrane (ITM) unit. The ITM unit separates oxygen from the preheated air. The separated oxygen is injected into the oil well to burn part of the well's oil, thereby generating the heat required for thermally enhance oil recovery. Combustion of part of the well's oil reduces the viscosity of the remainder, enhancing extraction of oil from the well.
