Publication number: 20160064588Abstract: A lens device for concentrating light onto a photovoltaic target or mirrored surface is disclosed. The lens may be configured to receive and reflect at least a portion of incident light onto the photovoltaic target or mirrored surface, and pass a portion of incident light through the lens depending on the received light's particular angle of incidence. The lens may include a lens body having a first surface that extends away from a light incident base at generally a first acute angle relative to the base, and a collector surface extending from a distal end of the first surface toward the base at a second angle. The collector surface may include a photovoltaic target configured to receive a portion of light emitted from the base and to convert the received portion of light into electrical energy, or a mirrored surface configured to reflect light generally back to the origin.Type: ApplicationFiled: August 25, 2015Publication date: March 3, 2016Inventors: James B.

Patent number: 8207630Abstract: Techniques for DC-to-AC conversion are disclosed, and may be embodied in a solar inverter device that can operatively couple to a power grid. The device includes a photovoltaic (PV) stack including series-connected PV modules. Each PV module is associated with a capacitor for storing output of that PV module. A positive terminator circuit switches a negative end of the PV stack to ground during positive half of grid cycle, and a negative terminator switches a positive end of the PV stack to ground during negative half of grid cycle. A connecting branch couples each PV module output to a common bus, each branch including control circuitry configured to selectively couple the corresponding PV module output to bus. During a first half of grid cycle, some of the capacitors discharge to the grid while a balance of the capacitors charge in preparation for discharge during a second half of grid cycle.Type: GrantFiled: December 19, 2011Date of Patent: June 26, 2012Assignee: Stellaris CorporationInventor: James B.

Publication number: 20110067693Abstract: Apparatus and methods are disclosed for reducing or eliminating the need for an intermediate supporting rack in a solar panel installation, which in turn may lower the cost of the installation. In one exemplary embodiment, a mount design is provided that includes a mounting flange attached to or integrally formed with a first side of a solar panel frame. This first side and flange operate together with a second side of the solar panel frame that is designed to engage with the mounting flange and first side of an adjacent solar panel. The geometry of the first and second sides may be such that they engage upon installation. The engagement may further include pins or similar components protruding from one side of one solar panel to fit into corresponding holes in a side of an adjacent panel.Type: ApplicationFiled: September 22, 2010Publication date: March 24, 2011Applicant: STELLARIS CORPORATIONInventor: James B.

Patent number: 7875792Abstract: The present disclosure relates to a device for concentrating light onto a photovoltaic target. In one embodiment, the device may include a transparent concentrating lens having an outside surface and a top and bottom portion wherein the bottom portion may be configured to receive concentrated light. A photovoltaic strip including a conducting strip are then provided along with film adhered to at least a portion of the outside surface of the concentrating lens wherein the film engages the lens and positions the photovoltaic strip at the lens bottom portion. A dielectric fluid may then be located between the lens and the film.Type: GrantFiled: July 5, 2007Date of Patent: January 25, 2011Assignee: Stellaris CorporationInventor: James B. Paull

Publication number: 20100012187Abstract: Techniques are disclosed for protecting a photovoltaic device from the environment. An electrical interconnection is also provided for increased mechanical and electrical protection of the photovoltaic and electrical interconnections between lens cell assemblies configured in an array using an enclosed busway structure. Also provided is a method of leading the electrical contacts from the photovoltaic material within the lens cell assembly such that there is a positive seal provided by the lens encapsulating material. One such embodiment comprises a passage within the lens itself, which serves as a conduit for electrical leads from the photovoltaic material. The internal passage for electrical leads enables the ability to completely wrap and seal the lens assembly with encapsulating film, which in combination with an enclosed busway operatively coupling an array of lens assemblies, allows for a highly manufacturable and secure seal over the photovoltaic system.Type: ApplicationFiled: July 16, 2009Publication date: January 21, 2010Applicant: STELLARIS CORPORATIONInventors: James B.

Patent number: 4124017Abstract: This invention describes an improved solar energy collector which passively concentrates the rays of the sun. The collector comprises a transparent cover which collimates incident rays of light and directs such collimated sunlight towards an absorbing target wherein the radiation's energy is received and utilized. The transparent collector cover consists of a lamination of transparent plastic or glass elements. Sunlight incident on the cover over a range of angles is reflected internally between the sides of the elements. These elements are so shaped that internal reflections result in the sunlight becoming collimated. Specifically, the elements are curved so that the horizontal distance between the sides of adjacent elements remains constant whereas the length of a normal between the sides increases along the path of incident light.Type: GrantFiled: June 17, 1977Date of Patent: November 7, 1978Assignee: James B.
