摘要:
A solar tracking system with a plurality of tracking assemblies moved by a single motor. A method and system that prevents overloading the motor or tripping a circuit breaker due to an obstructed or impeded tracker includes sensing movement of the tracker assemblies and entering into obstruction clearing modes. Obstruction clearing mode 1 (OCM1) is a high frequency adjustable mode that prompts movement for an adjustable period of time. If movement commences, the system returns to a normal mode. If there is no movement, the system enters into an obstruction clearing mode 2 (OCM2) with is an adjustable lower frequency series of attempts. If there is no movement, no further attempts are made. Each of these steps are monitored and controlled remotely. There are two types of secure connections for drivelines, torque tubes or affixing driveline linkages for high torque conditions.

A solar tracker assembly comprises a support column, a torsion beam connected to the support column, a mounting mechanism attached to the torsion beam, a drive system connected to the torsion beam, and a torsion limiter connected to an output of the drive system. When an external force causes a level of torsion on the drive system to exceed a pre-set limit the torsion limiter facilitates rotational movement of the solar tracker assembly in the direction of the torsion, thereby allowing the external force to rotate about a pivot axis extending through the torsion beam. Exemplary embodiments also include methods of aligning a plurality of rows of solar trackers.

An innovative portable reflected light sensor for non-destructively measuring characteristics of performance enhancement coatings applied to substrates such as solar photovoltaic panels is described. The innovative sensor provides a light source and a photodetector for measuring light incident on a substrate surface from the light source, and reflected to the photodetector. The spot size of the illuminated region of the substrate is at least 1 cm2 in area, thus averaging over a relatively wide portion of the substrate surface relative to existing fiber optic devices. A single measurement may then be representative of the coating. The innovative portable reflected light sensor is adapted to measure substrates in the field, and is especially adapted for assessing coating quality during the coating process. The innovative sensor also comprises a signal processing circuit that performs analysis of the measurements and feeds back status of the coating to the operator for coating process control.

A frameless photovoltaic (PV) module system and methods secure solar panels directly to a fixed structure either individually or collectively as an array. Universal mounting brackets attached to the back of each solar panel module connect to one another and to mounting feet that anchor to the fixed structure. Mounting brackets interlock with mounting brackets on adjacent solar modules and include a quick release mechanism to connect to and disconnect from mounting feet appropriately selected for the given fixed structure or roof type.

A modular shade system with solar tracking panels includes a series of generally North-South oriented, spaced apart torque tubes, each torque tube having an axis, a series of panels mounted to at least some of the torque tubes to create spaced-apart rows of panels along the torque tubes, at least some of the panels being solar collector panels. The system also includes a shade structure, positioned at a selected location between selected ones of the torque tubes and above the support surface so to provide an enhanced shaded region thereunder, and a support structure. The support structure includes a first mounting assembly mounting each torque tube above the support surface for rotation about the axis of each torque tube and a second mounting assembly supporting the shade structure at the selected location. The system further comprises a tilting assembly selectively rotating each torque tube about its axis.

A system for solar energy utilization is described. The system comprises a solar receiver, a solar energy concentrator mounted on a pole extending from the solar receiver along the main axis of the system, and a solar tracking system. The solar receiver is configured for receiving solar energy from the sun and concentrating the received solar energy at a predetermined spot area. The solar receiver includes a plurality of flexible mirrors independent of each other and radially arranged around a main axis of the system. The flexible mirrors are configured to be either deployed for operation or collapsed, for example for transportation or in the cases of possible damage of the system. The solar energy concentrator is located at the predetermined spot area in which the solar energy reflected from said plurality of flexible mirrors is concentrated, and configured for converting the concentrated reflected energy into electric energy. The solar tracking system is configured for sensing position of the sun and tilting the system for directing the solar receiver towards the sun to receive and reflect maximum sunlight onto the predetermined spot area.
