Patent number: 9960730Abstract: A frame for mounting a plurality of solar tracking units is provided. The frame comprises a plurality of leg assemblies interconnected by trusses to provide a stable structure that is ballasted by the frame's own weight, rather than relying on external ballast such as concrete blocks. Each leg assembly is provided with a shaft with a mounting end for mounting a solar tracking unit. Each solar tracking unit includes an armature assembly and at least one motor for controlling the orientation and position of a solar panel mounted thereon. Solar tracking assemblies, each comprising the frame and plurality of solar tracking units, can be assembled in an array using connectors spacing the assemblies, thus providing enhanced stability. Each of the assemblies can be provided with a local control unit for controlling each individual solar tracking unit, and a global control unit may be used to control the local control units.Type: GrantFiled: February 11, 2015Date of Patent: May 1, 2018Assignee: MORGAN SOLAR INC.Inventors: Michael Sinclair, John Paul Morgan, Philip M. Chang, Dhanushan Balachandreswaran, Abdelkader Chellabi, Porter Arbogast, Richard Iannello

Patent number: 9337373Abstract: A photovoltaic light guide solar concentration apparatus has a deflecting layer, a light-guide layer optically coupled to the deflecting layer, a secondary optic and a photovoltaic cell. The photovoltaic concentration apparatus has a central optical axis that, in operation, is parallel to incident sunlight. A deflecting layer includes a plurality of focusing elements symmetrically arranged with respect to the central optical axis. The light-guide layer is optically coupled to the plurality of focusing elements of the deflecting layer. The light-guide layer has a reflective surface and a plurality of opposite facets symmetrically arranged with respect to the central axis and focused sunlight from the deflection layer enters the light-guide layer and is directed and trapped by the reflective surface and the opposite facets and guided inside the light-guide layer towards an exit aperture through total internal reflections.Type: GrantFiled: August 1, 2011Date of Patent: May 10, 2016Assignee: MORGAN SOLAR INC.Inventors: John Paul Morgan, Philip M. Chang, Stefan Myrskog, Nigel Morris

Publication number: 20150255658Abstract: The present invention is that of a solar energy system that uses a light-guide solar panel (LGSP) to trap light inside a dielectric or other transparent panel and propagates the light to one of the panel edges for harvesting by a solar energy collector such as a photovoltaic cell. This allows for very thin modules whose thickness is comparable to the height of the solar energy collector. This eliminates eliminating the depth requirements inherent in traditional concentrated photovoltaic solar energy systems. A light guide solar panel has a deflecting layer, a light guide layer and a solar cell in optical communication with the light guide layer. The deflecting layer receives light at a first surface and inputs the light into the light guide layer. The light guide layer propagates the light to the solar cell, which is aligned generally parallel to the input surface.Type: ApplicationFiled: May 25, 2015Publication date: September 10, 2015Inventors: John Paul MORGAN, Stefan MYRSKOG, Philip M.

Publication number: 20140150774Abstract: A solar tracker assembly for mounting one or more solar tracking units, which can be adapted for use with various solar energy modules such as photovoltaic modules and heliostat mirrors, is provided. Each assembly comprises a frame of four sides connected at leg assemblies, each leg assembly being adapted for mounting a solar tracking unit. The frame may be configured as an oblique-angled, rhombus or diamond frame with a cross member extending between the closer-spaced leg assemblies. A set of frames may be arranged in the field with adjacent sides of adjacent frames being parallel, with spacing arms of predefined lengths interconnecting adjacent pairs of frames, to provide a desired hexagonal grid spacing.Type: ApplicationFiled: September 5, 2013Publication date: June 5, 2014Applicant: Morgan Solar Inc.Inventors: Philip M. Chang, Jayiesh Singh, Sandy Li, Eric Morgan, Asif Ansari, Trevor Vaughan, Stephen Caelers
