Abstract:
The invention provides systems and methods for provisioning a site with a solar energy system. A system (100) according to an embodiment of the invention comprises a data collection module coupled to a user interface module (200) to receive from a user system (106) location information associated with the geographical location of the roof wherein the data collection module communicates with a source (109) of aerial map images to retrieve at least one map image of the roof based on the location information, and provides the retrieved image to the user interface module (200). The user interface module (200) enabes the user to interact with a displayed image of the roof to generate at least one roof dimension measurement for at least a portion of the roof and comprises an interactive, user-adjustable measuring tool (1107, 1117) the dimensions of which are calibrated based on a scale represented by metadata associated with the displayed image of the roof and which is configured to be used to determine the measurement of the roof in response to a user adjustment of the measuring tool (1107, 1117) corresponding to the displayed image. A sizing module (500) including an input for receiving the at least one roof dimension measurement is provided for determining solar system components suitable for installation on the roof based, at least in part, on the received roof dimension measurement.
Abstract:
A control system or controller solar module array may be operated by (i) programmatically determining, for a given time period, a demand for an output of the solar module array by one or more energy consuming resources at the target location; and (ii) affecting an efficiency of the solar module array based at least in part on the determined demand.
Abstract:
The method is for controlling a direct solar steam generator comprising a solar receiver having tubes (14, 16) fed with working fluid and subjected to concentrated solar energy for evaporating the working fluid into steam and flow actuators (18, 20), the position of each flow actuator (18, 20) affecting flow parameters in the tubes (14, 16). The method comprises controlling the positions of the flow actuators (18, 20) as a function of at least one control output of a model predictive controller (28) configured to predict the behaviour of the direct solar steam generator (2) as a function of inputs comprising independent and/or dependant parameters of the direct solar steam generation system (2).
Abstract:
The method involves generating a proposed pool schedule, and establishing future time period pre-settings for an operation of a remote energy generation plant (10). The proposed pool schedule is transmitted to a central control unit (24) over a computer network (22) e.g. wide area network. The schedule is transmitted from the central control unit to a remote control unit (36) over the computer network. The remote energy generation plant is automatically controlled by the remote control unit according to the schedule. An independent claim is also included for a system for operating a remote energy generation plant using a renewable energy source, comprising a central control unit.
