20100018518DETERMINATION OF SOLAR TRACKING ERROR - A system may include determination of power delivered to an intended load by a solar collector and determination of a solar tracking error of the solar collector based on the determined power. Some aspects include determination of a servo feedback signal based on the determined power, wherein determination of the solar tracking error includes determination of the solar tracking error based on the servo feedback signal. Determination of the solar tracking error may further include determination of the solar tracking error based on the servo feedback signal and on a relationship between a response of the solar collector and tracking error.01-28-2010
20130032135Apparatuses and Methods for Determining and Changing the Orientation of Solar Energy Capture Devices - An apparatus for capturing solar energy can include a solar energy capture device having an orientation plane and a sensor configured to determine a direction of gravity relative to a sensor plane. The solar energy capture device is configured to rotate about a pitch axis and a roll axis. The sensor plane can have an orientation that is fixed relative to the solar energy capture device. The orientation plane can he offset from the roll axis.02-07-2013
20100006087SYSTEMS AND METHODS FOR CONTROL OF A SOLAR POWER TOWER USING INFRARED THERMOGRAPHY - Systems and methods for directly monitoring energy flux of a solar receiver in a solar energy-based power generation system include measuring infrared radiation emanating from the solar receiver. Such measurement can be achieved using one or more infrared thermography detectors, such as an IR camera. Resulting thermal data obtained by the imaging can be used to determine energy flux distribution on the receiver. A user or a system controller can use the determined flux distribution to adjust heliostat aiming to achieve a desired operation condition. For example, heliostats can be adjusted to achieve a uniform energy flux distribution across the external surface of the receiver and/or to maximize heat transfer to a fluid flowing through the receiver within system operating limits.01-14-2010
20110297141Tilt Sensor and Method of Use - This invention relates to a system for tracking a solar energy collector and diagnosing the solar collector's operational status. More specifically, it relates to a system employing a 3-axis accelerometer to determine the orientation of a solar collector, the vibration experienced by that solar collector, whether that solar collector has experienced an impact, and initiating system position control and diagnostics based on that information.12-08-2011
20110271952SYSTEM FOR RECLAIMING SOLAR ENERGY IN BUILDINGS - The invention relates to a system for reclaiming solar energy in buildings, comprising a fluid inlet header pipe, a fluid outlet header pipe and a plurality of heat collector panels connected to the two pipes at ends thereof respectively. Fluid with a lower temperature from the fluid inlet header pipe enters into the heat collector panels, where it is heated to a higher temperature by the solar energy stored therein, and then discharges from the system via the fluid outlet header pipe for energy reuse. The heat collector panels are mounted on the inner surface of the cladding panels of the building, so that the outer appearance of the building will not be negatively influenced by the system.11-10-2011
20100170497Reciprocating solar engine - A reciprocating solar engine includes a) a seesawing platform having a central fulcrum support upon which the platform is moveably positioned to reciprocally rotate through a predetermined arc b) a first solar heat-receiving closed container located on the platform on one side of the support and a second solar heat-receiving closed container located on the platform on a second side of the support; c) a connecting tube connecting the first container and the second container; d) a fluid contained within at least one of the first and the second container, the fluid being evaporable from solar heat and condensable from shading from solar heat; e) a roof above the platform, having at least one window of which is located above the first container and at least one window of above the second container; f) shuttering devices connected to the roof and movable so that one window is closed while the other is open and vice versa; and, g) shutter device controls functionally connected to the shutter device and the platform such that the shutter device controls activate the shutter devices to a first rest position when the second solar heat-receiving closed container is at its arc base, and to the second rest position when the first solar heat-receiving closed container is at its arc base.07-08-2010

20090120427WATER HEATER OF ENDORSEMENT WITH IONIZED IGNITION AND CONTROL OF ELECTRONIC TEMPERATURE FOR HEATERS OF CIRCULATION FORCED WITH SOLAR APPLICATION OF ENERGY - The forced recirculation solar water heating system with a backup water heater works through an electronic card that initiates the operation and activation of the water recirculators when there is a difference of 2° C. between the panel and the storage tank [detected] by means of a bimetallic cable connected at one of the top ends of the panel and another bimetallic cable at the upper part of the storage tank, which has a series of safety check valves that prevent temperature loss due to hot water backflow to the hydraulic network or due to natural reverse recirculation, thus avoiding excess pressure in the system.05-14-2009
20120247453DEHYDRATION DEVICE - A dehydration device includes a solar energy collection device connected with a water source so as to transfer solar energy into thermo energy which heats water that is supplied from the water source. A water storage device includes at least one hot water tank which has a heater connected to the solar energy collection device. The water heated by the solar energy collection device is stored in the at least one hot water tank. A heat-exchange device has a pipe connected with the water storage device, and an air delivery unit which blows air toward the pipe to form hot air to dehydrate foods. A windmill generates electric power which is provided to the dehydration device. The dehydration device uses green energy to dehydrate foods to keep proper freshness and nutrition. The dehydration device is easily moved and friendly to the environment.10-04-2012
20110220091METHOD AND APPARATUS FOR OPERATING A SOLAR ENERGY SYSTEM TO ACCOUNT FOR CLOUD SHADING - Images representative of cloud shadows with respect to a field of heliostats can be used to adjust operation of a solar energy system. For example, images of a field of heliostats and shadows produced by the clouds can be obtained. Additionally or alternatively, images of the sky and clouds can be obtained. The images can be analyzed to determine a shading parameter. Based on the shading parameter, an operating parameter of the solar energy system can be changed or maintained. For example, the operating parameter may include aiming directions for one or more of the heliostats. Cloud characteristics in addition to the location of the cloud shadow can be used in determining the shading parameter. Such characteristics can be used in determining if and/or how to change the operating parameter of the solar energy system.09-15-2011
