Abstract:
An energy-management application may be resident on a mobile computing device to access information and control components associated with one or more solar generation sites. A graphic user interface presents multiple pages to both 1) monitor information regarding the solar generation sites and 2) control components within the solar generation sites from the mobile computing device. The application detects as an input on a currently displayed page from the sequence of multiple pages both a rate and a pattern of finger swipe gestures made on the currently displayed page. The application, in response to detection of both the rate and pattern of the finger gestures on the touch screen display, performs at least one of 1) activation of one or more of the data items, one or more of the links, or one or more of the objects, and 2) navigation to another page in the sequence of pages.
Abstract:
In a hot water supply system having a solar heater that heats a heating medium with absorbed solar heat, a cogeneration unit that heats the medium by heat exhausted from an engine, a hot water supply unit with a heat exchanger for heat-exchanging between the medium and water supplied from a water supply source to generate the hot water, a medium circulator that circulates the medium among the solar heater, cogeneration unit and heat exchanger, an electric heater that heats the hot water with the power generated by the generator, a heat absorption amount to be adsorbed by the solar heater is estimated and operations of the cogeneration unit and the electric heater are controlled based on the estimated heat absorption amount, thereby enabling to improve energy efficiency of the entire system.
Abstract:
In a method for forecasting shadowing of a photovoltaic (PV) system due to cloud formation or movement, part of the firmament is imaged with fisheye optics onto the input optics of a digital camera. Pixel groups associated with luminous intensity ranges are formed. The spatial arrangement of the groups is analyzed to forecast shadowing of a photovoltaic system. A line extending from the PV system to the sun is formed and is continuously tracked. A reference line located inside a region around the line is formed. Passage of clouds across a reference line is analyzed. The result of the analysis is used to increase the electric power from the PV system to a minimum value through supply of additional backup energy or to reduce the electric power consumption by disconnecting users to ensure that key users do not experience a drop in supplied power below a minimum value.

In one embodiment, an apparatus is provided. The apparatus includes a first rail coupled to a second rail, a third rail coupled to the second rail, and a fourth rail coupled to the first rail and the third rail. The apparatus may form a rectangular frame from the four rails. The rails may be coupled through use of corner connectors or may be mitered and coupled through use of brackets in an abutting relationship. Additionally, further rails may be added by interposing the additional rails between a pair of the first, second, third and fourth rails, to extend the frame, and such additions may involve connectors or abutting rails and brackets, for example. The rails may have support ledges. Alternatively, the rails may have slots allowing for support brackets which slide along the slots. Moreover, the rails may be anchored using roof anchoring components to various surfaces. Additionally, the rails may support photovoltaic or other solar panels, and may have caps or top brackets to maintain the position of such solar panels.In another embodiment, a method is provided. The method includes reviewing solar days of a site. The method further includes reviewing geographical features of the site. Also, the method includes estimating a guarantee of available solar energy for the site. Moreover, the method includes installing a solar system at the site.
Abstract:
An automated method causes a terrestrial solar cell array to track the sun. The solar cell system includes motors that adjust a position of the array along different respective axes with respect to the sun, wherein a first motor adjusts the inclination angle of the array relative to the surface of the earth and a second motor rotates the array about an axis substantially perpendicular to that surface. The method includes (a) using a software algorithm to predict a position of the sun at a future time; (b) using a computer model to determine respective positions for the motors corresponding to the solar cell array being substantially aligned with the sun at the future time; and (c) activating and operating the motors at respective particular speeds so that at the future time the solar cell array is substantially aligned with the sun.
Abstract:
A modular geothermal measurement system that provides for the pumping of a heat transfer fluid. The modular unit simplifies on-site installation time by reducing the number of distinct components to be installed and allows for the optional incorporating of additional heat sources or sinks, whereby the length of ground loop can be reduced, further reducing installation costs. The modular measurement system further allows for the growth of the system over time by adding modules, increasing the ground loop pumping power while providing energy transfer data specific to each thermal load. A controller having an energy control module provides energy control points. Such a system allows the beneficiary of a geothermal investment to be billed for their benefit, enabling the investor to capture the economic benefit of the investment.
Abstract:
When using a solar concentrator to obtain energy collected by a sun, it can be beneficial to place the concentrator accurately. As the concentrator moves, a position of the concentrator with respect to gravity can be determined, commonly though use of an inclinometer. A comparison can be made of the determined position against a desired position can be made to determine if the concentrator should move. If a positive determination is made, then the concentrator can be moved accordingly.
