20090038607 | Motorized tracking device - A mount and tracking mechanism for solar panels and antennae. The tracking mechanism comprises electric motor actuators which operate a small gear reducer drive. The output of the small reducer drive is connected to the input of a large gear reducer drive. The output of the large gear reducer drive moves the solar panels or antennae. This arrangement results in a substantial increase in the torque of the output shaft of the large gear reducer drive. | 02-12-2009 |
20090101135 | STRONG WIND PROTECTION SYSTEM FOR A SOLAR PANEL - A detector is used on a solar panel to detect the strength of the wind blowing at it.

20130133641 | SYSTEMS, METHODS, AND DEVICES FOR WIND-RESPONSIVE OPERATION OF SUN-TRACKING ASSEMBLIES - The present disclosure relates to operating sun-tracking assemblies in response to one or more wind parameters or conditions. By judiciously reorienting one or more sun-tracking assemblies in response to detected or predicted wind conditions, the potential for wind- damage may be reduced. Some of the sun-tracking assemblies may act as a wind buffer for more fragile or sensitive components, thereby protecting them from damage. Such wind- sensitive components may be other sun-tracking assemblies arranged downwind from the reoriented assemblies. The downwind sun-tracking assemblies may continue to operate normally or substantially normally (i.e., to track the sun) despite the presence of the wind. During times of reduced or no wind, the sun-tracking assemblies may continue to track the sun until wind conditions require reorientation. | 05-30-2013 |
20130247899 | Calibration System for Solar Collector Installation - A solar concentrator calibration tool that compensates for inconsistencies in the fabrication, assembly and installation of a solar collector system, permitting the solar collector to perform optimally. The calibration tool provides feedback information to a supervisory control processor, allowing the processor to compare the expected position of the sun to the “actual” position found by the calibration tool. The processor then generates a calibration signal, thereafter used by the collector's movement control mechanism, to compensate the tracking of the solar collector to accurately follow the movement of the sun, unconstrained by the effects of the construction inconsistencies. | 09-26-2013 |
20140182577 | DRIVE WITH INTEGRATED INCLINATION SENSOR - A drive can include a positional sensor within an outer housing of the drive so as to provide an output indicative of a position of the drive. The positional sensor can be an inclinometer. The inclinometer can be used for feedback control of an inclination of the drive. The drive can further include control electronics within the same housing, so as to provide feedback control of a motor of the drive. The control electronics can include an input for receiving a requested inclination and can be configured to drive the motor until the inclinometer outputs a signal indicative of the requested angle. | 07-03-2014 |

20100186732 | FLUID HEATING SYSTEM - This invention relates to a fluid heating system, wherein the fluid is capable of being heated by means of solar energy, the fluid heating system including:—an outer housing;—an inner housing contained within the outer housing and including an absorbent material core located within the inner housing to define a flow passage between it and the walls of the inner housing; the absorbent material core being suitable for absorbing solar energy transmitted through the outer and inner housings; and—wherein the outer housing; inner housing; and the absorbent material core are arranged such that solar energy is transferred through the fluid in the flow passage before being absorbed by the absorbent material core. | 07-29-2010 |
20110203573 | Solar Collector - The invention relates to a solar collector. The collector has a heat regulating medium which defines a cavity therein. An aperture communicates with the cavity so as to allow solar energy incident on the aperture to enter the cavity. An energy collection device is disposed in the cavity and in thermal contact with the heat regulating medium to collect solar energy entering the cavity. | 08-25-2011 |

20120024282 | METHOD AND CONTROL SYSTEM FOR OPERATING A SOLAR POWER TOWER SYSTEM - A solar energy collection system includes a primary solar receiver and a secondary solar receiver. The secondary solar receiver generates steam using energy from solar radiation incident thereon. The primary solar receiver receives the generated steam from the secondary solar receiver and superheats the steam using energy from solar radiation incident thereon. A plurality of heliostat-mounted mirrors reflects incident solar radiation onto one of the primary and secondary solar receivers. A controller aims a portion of the heliostat-mounted mirrors at the primary solar receiver such that a predetermined thermal profile is provided on a surface of the primary solar receiver. | 02-02-2012 |
20130239948 | LINEARLY CONCENTRATING SOLAR COLLECTOR AND METHOD FOR REFLECTOR TRACKING IN SUCH A SOLAR COLLECTOR - The basis for the function of a linearly concentrating solar collector lies, in simple terms, in the fact that reflectors reflect incident sunlight onto a receiver tube through which a heat-absorbing medium flows. Owing to the rotation of the Earth, the reflectors need to be adjusted regularly, however, in order to ensure that the sunlight hits the receiver tube. Known tracking methods use calculated positions of the sun for this purpose, which, in the case of structural deviations, for example as a result of expansion and material stress, results in inaccuracies and losses in efficiency. The invention is intended to improve the tracking of the reflectors in such a linearly concentrating solar collector. This is achieved by virtue of the fact that the radiation intensity in the region on both sides next to the receiver tube is measured and, by means of regulation, in the case of uneven emission on both sides of the receiver tube, the reflectors are tracked to such an extent that the radiation intensity on both sides of the receiver is the same and thus the maximum of the radiation intensity is on the receiver tube. | 09-19-2013 |
20130255665 | SNOW MELT SYSTEM FOR SOLAR COLLECTORS - A solar collector system having several evacuated tube solar collectors arranged together, a conductor arranged on the solar collectors, a power source for sending electricity through the conductor, and an indicator connected to the conductor to indicate when electricity is flowing through the conductor. A snow sensor connected is connected to the conductor adjacent the evacuated tube solar collectors and a controller is connected to the snow sensor. The controller controls the electricity flow through the conductor and allows electricity to flow when the snow sensor senses snow covering the snow sensor, and stops the electricity flow when the snow sensor is no longer covered. The electricity flow heats the conductor, which in turn melts the snow on the collectors. | 10-03-2013 |

20100288265 | SOLAR COLLECTOR PANEL WITH TEMPERATURE CONTROLLED BI-DIRECTIONAL AIRFLOW - A solar collector panel is disclosed for heating ventilation air to a building interior, featuring a method for protecting the build-in solar cell panel from long term excessive heating, leading to damage of the panel, if the solar collector panel is turned off. Furthermore the solar collector panel features a method to create active cooling ventilation to a building interior during summer, by using a forced bi-directional airflow. The above is achived by using a build-in temperature controller. The temperature controller, located within the heater, is powered by a solar cell panel. The temperature controller relays a signal to one or more solar powered fans, to change the direction of the air flow through the heater, at a preset temperature measured within the panel. | 11-18-2010 |
