20100000517 | SUN POSITION TRACKING - Tracking the position of the sun is provided where light from sources other than direct sunlight can be ignored. In particular, lights from various sources can be passed through differently angled polarizers to determine radiation energies from the polarizers. This can indicate whether the original light is polarized or substantially non-polarized, like the sun. Additionally, the light can be passed through a spectral filter to reject light not falling within a spectrum of wavelengths or having weak intensity with respect to direct sunlight. Subsequently, the light can pass through a ball lens and quadrant cell configuration to optimally align a device or apparatus to receive the direct sunlight. Additionally, the size of a focus point of the light through the ball lens and onto the quadrant cell can determine a collimation of the light, which can indicate direct sunlight as well. | 01-07-2010 |
20100000519 | POLAR MOUNTING ARRANGEMENT FOR A SOLAR CONCENTRATOR - A solar collector can be rotated and tilted about a polar mount. The solar collector can be designed such that the center of gravity of the collector is aligned with the axis of the polar mount facilitating the use of smaller positioning devices. The collector can be placed in a position to prevent damage by inclement weather and allow easy access for maintenance and installation. | 01-07-2010 |
20100000594 | SOLAR CONCENTRATORS WITH TEMPERATURE REGULATION - Systems and methods that regulate (e.g., in real time) heat dissipation from solar concentrators. A heat regulating assembly removes heat from the PV cells and other hot regions, to maintain the temperature gradient within predetermined levels. A control component can regulate (e.g., automatically) operation of valves (which the cooling medium flows through) based on sensor data (e.g., measurement of temperature, pressure, flow rate, velocity of the cooling medium, and the like throughout the system.) | 01-07-2010 |
20100002237 | SOLAR CONCENTRATOR TESTING - A system (and corresponding methodology) for testing, evaluating and diagnosing quality of solar concentrator optics is provided. The innovation discloses mechanisms for evaluating the performance and quality of a solar collector via emission of modulated laser radiation upon (or near) a position of photovoltaic (PV) cells. The innovation discloses positioning two receivers at two distances from the source (e.g., solar collector or dish). These receivers are employed to collect modulated light which can be compared to standards or other thresholds thereby diagnosing quality of the collectors. | 01-07-2010 |
20100004797 | PLACEMENT OF A SOLAR COLLECTOR - When using a solar concentrator to obtain energy collected by a sun, it can be beneficial to place the concentrator accurately. As the concentrator moves, a position of the concentrator with respect to gravity can be determined, commonly though use of an inclinometer. A comparison can be made of the determined position against a desired position can be made to determine if the concentrator should move. If a positive determination is made, then the concentrator can be moved accordingly. | 01-07-2010 |
