NOVELTY - The system has a primary loop comprising a solar array and a heat storage unit for receiving and storing thermal energy from the solar array. A secondary loop is in operative communication with the primary loop. The solar array comprises reflector dish assemblies. Each dish assembly has reflector dishes arranged in close proximity to each other so as to obtain high sunlight concentration ratio for providing high efficiency of conversion from heat to electricity.    USE - System for solar energy-based electrical power generation and heat storage. Can be used in electrical power generation and thermal storage plant (claimed).    ADVANTAGE - The very small concentrated sunlight receiver is non-movable due to dish anti-collision function and is enclosed in vacuum to provide for minimum re-radiation losses. Helium coolant is circulated in the primary loop to ensure corrosion-free and high-temperature operation. The dishes are raised to permit for service from below, and are in close proximity to each other to get maximum sunlight collection per unit area. The entire primary loop pipe is enclosed in vacuum surrounded by specially designed multi-layer reflective insulation to ensure minimum radiation losses. All welded joints in the system are provided with thermal expansion and contraction. The dishes with the composite sheets can be formed in required shape easily, allowing for cheap, fast and large-scale production. The dishes may be in form of square-shaped parabolic dishes supported solely on primary coolant pipe system to cover maximum area. The self-sealing design ensures that only very small section of the primary loop will malfunction, ensuring continued functioning of the plant at full capacity. Automatic dust removal system minimizes dust deposition on the dishes by using air ionization and filters to capture dust. Automated dish cleaning using an automated dry cleaning system results in water and labor cost savings. Wind protection is ensured by using strategically placed dust filters. Natural convection air cooling system removes waste heat, eliminating huge water consumption of power plant. Ambient air temperature is kept in desirable range regardless of significant energy removal. The plant has no water requirement, allowing the plant to be set up in the driest and most inhospitable and remote deserts. Enclosed transparent air-tight housing allows the system to be used in areas where rainfall is frequent. The plant design ensures that the dishes require much less cleaning through the entire plant life. The use of a sand and steel heat storage unit of any size and capacity allows for very low heat storage construction cost. The heat storage unit can operate at extremely high temperatures and may be provided with secondary steel core for high power ramp up in very short time. The use of the system realizes 24 hours a day, 365 days per year power generation capacity without need of back up of fossil power plants. The system also provides sufficient heat storage for day in event of continuous cloud cover or other natural uncontrollable event.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram of a power plant.
