In general, the present invention relates to computer implemented systems and methods for providing services to a network of customers, more specifically to services enabled by methods comprising the collection, aggregation, and analysis of data in a central database from a plurality of systems that are not otherwise associated with one another to provide performance metrics and most particularly to the establishment and improvement of various performance metrics related to the execution of customer activities and the initiation of specific actions related to performance in comparison with such metrics. More specifically, the present invention relates to computer implemented services enabled by systems and methods comprising the collection, aggregation, and analysis of data related to the installation and operation of renewable energy systems comprising solar energy, wind turbine energy, tidal energy, geothermal energy, and the like, or to distributed energy generation systems comprising waste-to-energy generation systems, fuel cells, microturbines, diesel generators, and the like.
There is increased interest in the development and deployment of renewable energy systems comprising solar energy, wind turbine energy, tidal energy, geothermal energy, and the like, or to distributed energy generation systems comprising waste-to-energy generation systems, fuel cells, microturbines, diesel generators, and the like. This interest is being driven by a number of factors including a limited supply of fossil fuels, increased pollution from the acquisition and use of fossil fuels, global warming considerations, rising costs of fossil fuels, the loss of natural lands due to the construction of fossil fuel power plants, continued utility grid degradation and blackouts, unpredictable energy prices, the need for local power generation in disaster recovery situations, the need to move away from centralized power plants to distributed energy systems for homeland security, and the like. Advancements in the development of renewable energy and distributed energy generation technologies have overcome earlier impediments such as poor efficiency, installation difficulty, high cost, high maintenance, and the like and are presently offering increasingly attractive alternatives to fossil fuel power systems in the generation and delivery of electric power.
One of the issues faced by the renewable energy and distributed energy generation industries is that the adoption and deployment of such systems is often sporadic and not well coordinated. The decision to invest in and install a renewable energy or distributed energy generation system is typically made at the individual entity level rather than as a planned activity for an entire community. For economy of language, in this context, an “entity” may comprise an individual, a company, an office building, a shopping mall, a shopping center, a sports complex, or other such organization, business, or group investing collectively in a source of energy. Consequently, the renewable energy and distributed energy generation industries often lack the coordinated, integrated infrastructure that is typically common in other industries. The lack of infrastructure inhibits the adoption and installation of new renewable energy and distributed energy generation systems and does not allow these industries to gain advantages due to cooperation or economies of scale to lower costs, increase acceptance and deployment, and attract additional investment capital.
Accordingly, there is a need for further developments in methods and systems to facilitate the connection and cooperation of the wide variety of entities and individual implementations of renewable energy or distributed energy generation systems to improve efficiencies, lower costs, facilitate new services, facilitate management and improvement of the energy production and distribution system as a whole, facilitate and improve training and education, facilitate energy commerce, and the like. In particular, there is a need for improved systems and methods to improve the guarantees made to End Users or other Customers based on aggregated data from a plurality of previously installed systems.
Advancements in the development of renewable energy and distributed energy generation systems have overcome, to a large extent, earlier impediments such as poor efficiency, installation difficulty, high cost, high maintenance, and the like. Specifically, advancements in the technology associated with the capture and conversion of solar energy into useable electricity has led to an increased adoption and deployment rate of solar energy generation systems. However, the infrastructure associated with collecting and analyzing data associated with the distribution infrastructure, system performance, system response, system efficiency, costs, savings associated with the system, and the like has not grown at the same pace as the implementation of solar energy generation systems. Systems and methods for the collection, aggregation, and analyzing of this data and providing services based on the results of the analysis have been developed as part of some embodiments of the present invention.
In some embodiments of the present invention, the data collection systems and methods cited above may use a local communications device installed at the site of the renewable energy generation or distributed energy generation system to collect data on the system comprising system ID, location, performance, calibration, ambient conditions, efficiency, temperature, wind speed, wind direction, solar irradiance, energy generation, device status flags, and the like. Typical data collection systems comprise embedded sensors, external sensors, embedded computers, and the like. Typical local communications devices comprise modems, routers, switches, embedded computers, wireless transmitters, and the like. The data may be transmitted via a wireless or hardwired network or other communication means to a secure, central database where the data is aggregated with data from other systems and analyzed to provide value added services to the members of the renewable energy or distributed energy generation supply chain. Examples of suitable networks comprise the Internet, a Local Area Network (LAN), a Wide Area Network (WAN), a wireless network, cellular networks (e.g., GSM, GPRS, etc.), combinations thereof, and the like. Various embodiments of the present invention include security features such that proprietary or business-sensitive data is not accessible among different business entities, thereby providing all entities access to aggregated information while compromising the security of none.
Various embodiments of the present invention relate generally to systems and methods that utilize the secure, centrally collected, aggregated, and analyzed data to provide a number of beneficial services. The services may be desirable and useful to many “Supply Chain Entities” within the renewable energy or distributed energy generation system supply chain. For economy of language, we use the term, Supply Chain Entity or Entities to refer to one or more of the “Installation Technician”, the “Value Added Reseller (VAR)”, the “System Integrator”, the “Original Equipment Manufacturer (OEM)” component supplier, the “local energy utility”, various local government agencies, the Project Financier or Investor, the Distributed Utility provider, among others. These labels have been used for convenience in the context of the present teaching. It will be clear to those skilled in the art that those entities or parties that provide similar functions and services within the supply chain may use a wide variety of names and labels. These labels do not limit the scope of the present invention in any way.
In some embodiments of the present invention, the aggregated data may be used to offer services to the System Integrators that improve the offer of System Performance Guarantee commitments. The services may utilize a model of benchmark system performance established by the System Integrators or established from aggregated data based on system configuration details comprising OEM sub-modules, installation region, system orientation, system tilt angle, expected shading, system tracking features, system tracking capabilities, date, historical data, and the like. Typically, the System Integrators may select a coefficient between 0 and 1 to serve as a safety factor and calculates the System Performance Guarantee commitment as the multiplication of the model result and the coefficient. New system performance data may be collected and aggregated into the database and the System Performance Guarantee commitment may continue to improve over time as the benchmark system performance improves. The System Integrators may enjoy the benefits of improved performance guarantee accuracy, competitive differentiation by offering a higher performance guarantee, increased market share, increased End User satisfaction, and the like.
In some embodiments of the present invention, the aggregated data may be used to offer services to the other Supply Chain Entities that improve the offer of other kinds of System Performance Guarantee commitments. Examples of other kinds of System Performance Guarantee commitments comprise system installation costs, service warranties, OEM manufacturer parts warranties, and the like. The services may utilize a model of benchmark system performance established by the Supply Chain Entities or established from aggregated data based on system configuration details comprising OEM sub-modules, installation region, system orientation, system tilt angle, expected shading, system tracking features, system tracking capabilities, date, historical data, and the like. Typically, the Supply Chain Entities may select a coefficient between 0 and 1 to serve as a safety factor and calculates the System Performance Guarantee commitment as the multiplication of the model result and the coefficient. New system performance data may be collected and aggregated into the database and the System Performance Guarantee commitment may continue to improve over time as the benchmark system performance improves. The Supply Chain Entities may enjoy the benefits of improved performance guarantee accuracy, competitive differentiation by offering a higher performance guarantee, increased market share, increased End User satisfaction, and the like.

In an exemplary embodiment of the present invention, the systems and methods may be applied to a solar energy generation system. However, the solar energy example does not limit the scope of the present invention in any way. The systems and methods described herein may be applied to any general system. Specifically, the systems and methods described herein may be applied to any general energy system such as an energy consumption system, an energy generation system, an energy storage system, combinations thereof, and the like. More specifically, the systems and methods described herein may be applied to any renewable energy generation comprising solar energy, wind turbine energy, tidal energy, geothermal energy, and the like, or distributed energy generation technology comprising waste-to-energy generation technologies, fuel cells, microturbines, diesel generators, and the like or any combination thereof. In the context of the present teaching, a system comprising more than one type of system as listed above will be designated a “hybrid” system.
Typically, the solar energy system may be installed by an Installation Technician following an established installation checklist. The system may be connected to a central database via a network. Examples of suitable networks comprise the Internet, a Local Area Network (LAN), a Wide Area Network (WAN), a wireless network, cellular networks (e.g., GSM, GPRS, etc.), combinations thereof, and the like. In this exemplary embodiment, System Identification Data are collected at the point of sale by the System Integrator or the VAR, said System Identification Data comprising, End User identification, system warranty information, system performance guarantee commitment information, expected system power output, and the like. The System Identification Data are static in time meaning that they may not generally change once established. The System Identification Data may be entered into the central database and serve as a unique identifier for the system. System Configuration Data are collected during the manufacture and testing of the system, said System Configuration Data comprising, system configuration with OEM component identification, system wiring details, system tracking features, system tracking capabilities and the like. The System Configuration Data are generally static in time meaning that they may not generally change once established. However, the System Configuration Data may change during periods of service, upgrades, or enhancements to the system. The System Configuration Data may be entered into the central database and associated with the unique System Identification Data previously entered. System Installation Data are collected at the time of installation, said System Installation Data comprising, VAR identity, Installation Technician identity, installation region, system orientation, system tilt angle, expected shading, time to complete the system installation, number of errors during the system installation, an End User satisfaction index (EUSI), firmware revision, system parameter settings, and the like. In the context of the present teaching, “expected shading” may be associated with the area and time that the system is covered by shadows due to neighboring trees, building, structures, etc. It may be expressed in units of % coverage per hour for each time period of interest comprising months, seasons, years, billing periods, and the like. This quantity may be useful in estimating the performance of the system. The System Installation Data are static in time meaning that they may not generally change once established. The System Installation Data may be entered into the central database and associated with the unique System Identification Data previously entered. System Performance Data and ambient condition data are collected and continuously at a predefined interval after start-up of the system, said System Performance Data comprising, system response, system performance, ambient temperature, solar irradiance, conversion efficiency, current tilt angle, system energy output, current firmware revision, current system parameter settings, device fault and error codes, power, voltage, cumulative energy generated, and the like. The System Performance Data change with time and are entered into the central database as a time series with associated date and time stamps. The temporal System Performance Data are associated with the unique System Identification Data previously entered. The data correlated to the installation region may be aggregated to several levels of granularity, said levels comprising country, time zone, state or province, county, postal code, Global Positioning System (GPS) coordinates, and the like. Additionally, System History Data may be associated with each unique System Identification Data record. The System History Data captures changes in the System Configuration Data over time. Examples of System History Data comprise time-to-first-service-call, details of the service calls, steps taken to resolve the issues in the service calls, upgrades to the system configuration, new firmware revisions, new parameter settings, and the like. Entries in the System History Data typically contain date and time stamps so that changes may be tracked over the life of the system.
In some embodiments of the present invention, the systems and methods may be applied to a solar energy generation system as an example. Services may be provided to the System Integrators to improve the offer of System Performance Guarantee commitments. The services may utilize a model of benchmark system performance established by the System Integrators. The System Integrators may typically have a model that has been developed over time for use in their engineering design groups that they prefer. Alternatively, the services may utilize a model established from aggregated data from the centralized database based on system configuration details comprising OEM sub-modules installation region, system orientation, system tilt angle, system tracking features, system tracking capabilities, date, historical data, and the like. The services may use historical weather data from the centralized database as well as archived weather data to estimate the performance for the modeled system for all seasons of the year using Typical Meteorological Year (TMY) values for factors such as solar irradiance, number of rainy days, periods of low light, and the like. This a particularly advantageous aspect of some embodiments of the present invention because the system response and system performance may vary during the different seasons of the year due to differences in solar irradiance, temperature, number of cloudy days, typical cloud cover types and the like. The services allow the System Integrators to account for this variation in determining the System Performance Guarantee commitments.
Typically, the System Integrators may select a safety factor comprising a coefficient between 0 and 1. The System Performance Guarantee commitment to the End User for system response and system performance may be calculated by the multiplication of the result of the model and the coefficient. After the system is installed, calibrated, and begins operation, the system performance may be compared to the modeled performance to verify conformance. As mentioned previously, the variations due to weather and the different seasons may be included. The services may aggregate and normalize the system performance data for a plurality of systems. If the performance of the aggregation is consistently better than the model, the model may be enhanced or coefficient increased so that the System Integrators may improve their System Performance Guarantee commitments with confidence and achieve greater market share.
In some embodiments of the present invention, the aggregated data may be used to offer services to the other Supply Chain Entities that improve the offer of other kinds System Performance Guarantee commitments. Examples of other kinds of System Performance Guarantee commitments comprise system installation costs, service warranties, OEM manufacturer parts warranties, and the like. The services may utilize a model of benchmark system performance established by the Supply Chain Entities or established from aggregated data based on system configuration details comprising OEM sub-modules, installation region, system orientation, system tilt angle, expected shading, system tracking features, system tracking capabilities, date, historical data, and the like. Typically, the Supply Chain Entities may select a coefficient between 0 and 1 to serve as a safety factor and calculates the System Performance Guarantee commitment as the multiplication of the model result and the coefficient. The Supply Chain Entities may now accomplish this with confidence since the benchmarks may be established from a large database of actual values. New system performance data may be collected and aggregated into the database and the System Performance Guarantee commitment may continue to improve over time as the benchmark system performance improves. The Supply Chain Entities may enjoy the benefits of improved performance guarantee accuracy, competitive differentiation by offering a higher performance guarantee, increased market share, increased End User satisfaction, and the like.
In some embodiments of the present invention, the methods and procedures for using a model of benchmark system response and system performance to generate an expected result of system performance, selecting a coefficient between 0 and 1, calculating a guarantee by multiplying the model result by the coefficient, and monitoring the system performance and comparing it to the guarantee may follow the steps, 200-206, as outlined in
Through the services provided, the data may be manipulated and parsed by the various System Integrators subject to various security measures as discussed below. A plurality of standard procedures exists to aid in the manipulation of the data. Examples of suitable procedures comprise methods for calculating typical statistical values such as mean, median, average, standard deviation, maximum value, minimum value, variance, and the like. These procedures are listed as illustrations only and do not limit the scope of the present invention in any way. Alternatively, the System Integrators may develop and generate a custom procedure to extract and manipulate the data for their specific purpose.
The systems and methods may include a number of security measures to protect the intellectual property and confidential information for the various Supply Chain Entities of the renewable energy system supply chain. The security measures comprise software passwords, tokens, smart cards, biometric identification means, and the like. The security measures ensure that any specific System Integrator, VAR, or OEM manufacturer is only allowed access to the detailed data generated by systems under their specific responsibility. However, the System Integrators, VARs, or OEM manufacturers may request results based on the analysis of the aggregated data across the database so that they may compare their data to the larger population of systems.
The database may contain data from systems installed worldwide by a large number of Supply Chain Entities. The different pattern fill of the circles representing systems, 300, illustrated in
