Abstract: An urban concentrated solar power for mounting on a roof top is provided. The urban concentrated solar power has a heat receiver has a non-circular duct that distinguishes an insulated area with an insulation layer on the outer surface of the non-circular duct and a non-insulated area. The non-circular duct contains a heat transferring fluid which can reach temperatures of at least 500 degrees Celsius. A parabolic trough with an aperture of below 2 meters concentrates sunlight onto the non-insulated area of the non-circular duct of the heat receiver. The heat receiver can be placed in a glass tube. Due to roof top mounting the electricity can be generated in proximity of the user and as a result decrease net congestion. The low-cost heat receiver design will make electricity generated by urban CSP competitive with electricity from fossil fuel plants and PV combined with lithium-ion battery storage.
