20100179678 | PV Wind Performance Enhancing Methods - Pressure equalization between upper and lower surfaces of PV modules of an array of PV modules can be enhanced in several ways. Air gaps opening into the air volume, defined between the PV modules and the support surface, should be provided between adjacent PV modules and along the periphery of the array. The ratio of this air volume to the total area of the air gaps should be minimized. Peripheral wind deflectors should be used to minimize aerodynamic drag forces on the PV modules. The time to equalize pressure between the upper and lower surfaces of the PV modules should be maintained below, for example, 10-20 milliseconds. The displacement created by wind gusts should be limited to, for example, 2-5 millimeters or less. For inclined PV modules, rear air deflectors are advised for each PV module and side air deflectors are advised for the periphery of the array. | 07-15-2010 |
20090235975 | Tracking Solar Collector Assembly - A tracking solar collector assembly includes solar collector support structure, with at least one solar collector mounted thereto and first and second spaced apart pivotal support points defining a tilt axis, Southside supports, with first pivot connectors, and North side supports, with a base, a second pivot connector, and one or two support elements connected to the base and to the second pivot connector at the ends thereof. The first and second support points are pivotally connected to and supported by the first pivot connectors and by the North side supports, respectively. The assembly also includes a tilting assembly causing the solar collectors therewith to tilt in unison. | 09-24-2009 |
