1. Technical Field
The technical field relates to solar energy.
2. Background
Conventional electricity from utility companies is predominant among consumers due to predictable costs and ease of installation. Renewable energy options, such as solar energy systems, present many challenges to consumers that prevent widespread adoption. For example, energy production from a renewable energy system may vary with environmental conditions, unlike conventional electricity, and thus energy costs become more difficult to predict. Costs of equipment and installation for solar energy systems may also vary significantly by vendor, requiring the average consumer to understand the dynamics of the renewable energy market in order to make an informed decision. A solution is needed to provide accurate energy production and cost estimates to consumers while simplifying the process of adopting solar energy.
Computer-implemented systems and methods are disclosed for providing an online solar marketplace. In an embodiment, a geolocation may be received corresponding to a property. Available equipment, installation, and/or financing offerings may then be retrieved from a marketplace repository. The marketplace repository may store a plurality of service and equipment offerings from one or more equipment providers, installation providers, or financing providers. An integrated solar energy offering may be generated based on the retrieved equipment, installation, and/or financing offerings. A solar energy simulation may be performed for the solar energy offering to estimate energy production over a predetermined time period. The solar energy offering and energy production estimate may then be presented to a remote user of the online solar marketplace.
In an embodiment, pricing information may also be retrieved from the marketplace repository. A total installed cost for the solar energy offering may then be calculated based on the retrieved pricing information. In an embodiment, the calculated installed cost may be normalized based on a solar array capacity specified in the solar energy offering.
Further embodiments, features, and advantages of the invention, as well as the structure and operation of the various embodiments, are described in detail below with reference to accompanying drawings.
The accompanying drawings, which are incorporated herein and form part of the specification, illustrate the present disclosure and, together with the description, further serve to explain the principles of the disclosure and to enable a person skilled in the relevant art to make and use the disclosure.
The drawing in which an element first appears is typically indicated by the leftmost digit or digits in the corresponding reference number. In the drawings, like reference numbers may indicate identical or functionally similar elements.
In the detailed description that follows, references to “one embodiment”, “an embodiment”, “an example embodiment”, etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to effect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.
The value of a solar energy system offering on a particular rooftop is a function of both the levelized cost of energy (LCOS) of the electricity produced by the solar array and the cost of the conventional grid electricity that is displaced. LCOE can differ from rooftop to rooftop with the same equipment configuration due to differing intensity of solar radiation on each rooftop. The LCOE may take into account one or more of the following factors: cost of various equipment configurations, efficiency of various equipment configurations, cost of installation, quality of installation, cost of financing, form of financing, or other factor impacting cost.
In an embodiment, a solar energy marketplace quantifies and compares the potential value of a unique solar energy offering for a particular rooftop, including equipment, installation, and/or financing, by performing simulations of each solar offering on the rooftop. The rooftop may have a unique incidental solar radiation signature based on characteristics such as atmosphere, shade, slope and orientation. The value of each solar energy offering may then be compared against conventional electricity from the power grid.
Equipment providers 102 may be manufacturers or distributors of solar energy equipment. In an embodiment, the equipment provided may include, but is not limited to, solar modules (panels), inverters, racking and mounting systems, and/or balance of system (BoS). Solar modules may produce electrical current from incidental solar radiation. Inverters may convert the electricity produced from direct current (DC) to alternating current (AC) for consumption by businesses or residences. Racking and mounting systems may be used to secure the solar modules to a rooftop. BoS may include cabling, basic installation hardware, and/or other peripherals.
Installation providers 106 (also referred to herein as installers) may provide the following services such as, but not limited to, site verification and assessment, system design, rebate applications, permitting, engineering, and/or planning.
Financing providers 104 (also referred to herein as financing companies) may provide various financing programs for a solar energy offering such as, but not limited to, leases, power purchase agreements (PPAs), and loans. For lease programs, a financing company and associated investors may own, monitor, and maintain the solar energy equipment installed on the roof of a property, receive incentives (e.g., solar energy tax rebates), and charge the property owner a fixed monthly lease amount for the installed solar energy array. The lease payments may be competitively priced to be less than the monthly rate of energy displaced by the array. For PPAs, a financing company and associated investors may monitor and maintain the solar energy equipment installed on the roof of a property, receive incentives, and charge the property owner for the power produced by the solar energy array. The new cost of electricity may again be competitively priced to be less than the cost of energy displaced by the array. For loan agreements, a financing company may lend money to a property owner to acquire and install solar equipment. Interest may be charged on the loan, which again may be priced competitively to be less than the cost of energy displaced by the solar energy array.
In an embodiment, providers may provide offerings in more than one category.
for example, an equipment manufacturer or distributor may offer installation and/or financing, an installer may offer equipment and/or financing, and a financing company may offer equipment and/or installation. In this case, a provider may be included in more than one type category.
Each offering may have different specifications and costs. These may be updated by the provider or by an administrator of the marketplace system.
In an embodiment, an integrated solar energy offering may combine equipment, installation and financing in an authorized combination. Certain financing companies may only provide leases, PPAs and loans for systems that include certain equipment configurations. Equipment companies may also be restricted to only provide equipment to certain authorized installers. Certain installers may represent certain equipment and financing companies.
In an embodiment, each provider may price their elements separately, and the marketplace may combine them in an integrated offering. Pricing of offerings may also include a time period for which the offer is valid. Additionally, pricing of offerings may reflect the system size, roof type, and other factors, as described further below. Equipment and service prices may be stored in marketplace repository, such as marketplace repository 940 of
Labor costs 202 may include typical installation costs associated with a solar energy system, such as but not limited to, site verification and assessment, system design, and equipment installation. Equipment costs 204 may be associated with solar modules (panels) included in the system. Equipment costs 206 may be associated with inverters included in the system. Equipment costs 208 may be associated with racking and/or mounting systems to secure the solar modules to a rooftop. Administrative costs 212 may include, but are not limited to, permitting, auditing, and paperwork costs.
In a market where solar energy is less competitive with conventional electricity, for example due to low conventional electricity rates, poor renewable energy incentives, or low insolation (incidental solar radiation), offerings may be priced more competitively. Additionally, a large solar energy system, for example larger than 6 kW, may cost less per Watt than a smaller system due to fixed overhead for setup, logistics, and soft costs that may be incurred. Price may also be reduced through lower cost components, such as polycrystalline modules and string inverters.
An example system might be priced at $1.62 per Watt if the system is purchased for cash. In an embodiment, $0.92 of this cost may be allocated for equipment and $0.70 may be allocated for labor and installation. For an average 6.5 kW system, a total of $10,530 in cash may be paid, with $5,980 going to the equipment provider and $4,550 going to the installer.
In an embodiment, each equipment and installation provider may enter their base price for a standard configuration. Equipment and installation providers may then enter the price of adders 210, which represent additional costs that may be incurred. These may be fixed cost or calculated on a per-Watt basis. Example adders may include, for example, the following:
Example fixed cost adders may include, for example, the following:
In an embodiment, promotions may also be created, such that a specific price may be offered for a particular time-period. Descriptions of equipment, and the equipment's suitability for particular environments, may be entered by providers or system administrators, or uploaded directly from a provider's system. Similarly, descriptions of installers may be included to distinguish the capabilities of the installer.
Examples of equipment description fields that may be added may include, but are not limited to, name of equipment manufacturer, model of equipment, brand logo, equipment origination (e.g., country where made), size and/or power of solar module, equipment warranty, and equipment efficiency rating.
Examples of installer description fields that may be added may include, but are not limited to, name of installer, brand logo, company values, company origin, leadership biographies, number of years of solar installation experience, number of completed projects, workmanship warranty, insurance coverage, number of employees, and company revenue.
In an embodiment, the pricing model may take into account additional discounts, rebates, federal incentives, and/or local incentives to reduce the installed cost of the solar energy offering. For example, residential renewable energy tax credits may be taken into account to estimate the installed cost of the solar energy offering.
Once a price for a solar energy offering has been established via the pricing model, financing may be added. For a lease or a PPA, a look-up table of monthly payment rates may be created based on the requirements of the fund, which typically include IRR (internal rate of return) and other factors. From the fund criteria, a look up table may be created with system size, cost, location and production estimates. The lease pricing may be recalculated based on an upfront payment that may be made by the property owner. Loans may be calculated based on the interest, term, and fees associated with the amount that is borrowed.
In an embodiment, each offering represents a solar array with a particular performance profile, installed cost, financing program and other characteristics. A solar energy simulation and energy production analysis may be run for each offering on each individual property, as discussed further with respect to
For example, the energy production part of the simulation may be performed on every property in a broad region. The results may then be stored in a data repository, such as marketplace repository 940 of
Detailed installation models and planning may be performed on the virtual property models to produce an optimal system design for best solar performance. These may also be made code compliant, as, in an embodiment, the marketplace may be coupled to a building code database and permitting database via a network, such as the Internet.
When running a simulation, various factors may be taken into account to determine the best design and offering. As illustrated in
In another embodiment, a property scene may be constructed from ground-level photographs taken from a consumer mobile device or GPS-enabled camera. In this embodiment, a user may use a mobile device with location systems and camera to take photographs of roof installation sites and surrounding areas from multiple ground location points. Dimensional estimations may be performed by a computing device, such as the computing system of
In both embodiments, a 3D scene model that includes elevation and positional data for both the site of the solar array and surrounding area may be reconstructed. In various embodiments, the user may select the desired roof or ground surface, facet or facets for solar installation, or this may be determined by the system based on available incidental solar radiation. The system may arrange the components of the solar array, or they may be manipulated by the user. Permitting and code compliance may be validated and enforced in the 3D model. These may include setbacks from the edges of the roof, resistance to wind and support under the weight of snow. In an embodiment, permitting and code compliance values may be available in the system through an API.
Equipment elements such as racking, mounting, size and efficiency of panels and efficiency of inverters may be used to determine specific performance, which may be optimized in the simulation. In an embodiment, a full plan-set for installation may be output to a user device.
In an embodiment, the system design may be overlaid on the photographs. The system design may also be presented in augmented reality systems, for example GOOGLE GLASS, for use by installers. The presentation may also be viewed by the property owner as an overlay in a photograph or superimposed on the roof through the augmented reality system. Further details of data collection and property construction are described in U.S. patent application Ser. No. 13/117,419, filed May 27, 2011, which is incorporated by reference herein in its entirety.
In an embodiment, an energy production analysis may be performed on data and energy production estimates derived from the solar energy simulation. A levelized cost of energy may be determined for the life of the solar energy system or another period of time based on the energy production estimates and expected cost of conventional electricity. Conventional electricity costs may be calculated based on average electricity costs in one or more regions, adjusted based on an estimated rate of energy inflation. A total monthly or overall cost for a solar energy offering may then be computed based on the levelized cost of energy for solar and the expected conventional electricity costs. In an embodiment, the total cost of the solar energy offering may include both solar energy costs and supplemental conventional electricity costs (e.g., the amount of energy needed in addition to solar energy production). Supplemental conventional electricity costs may be calculated as a proportion of the expected cost of conventional electricity for the additional amount of energy needed.
In an embodiment, the levelized cost of energy for the solar energy system may take into account federal and/or local incentives, such as solar alternative energy credits. For example, the solar energy system may generate renewable energy credits based on an amount of carbon dioxide equivalent (CO2e) emissions reduced. In a non-limiting example, energy produced by the solar energy system may be registered with an appropriate registry in exchange for Solar Renewable Energy Certificates (SRECs), which can then be sold to offset costs of solar energy. The expected revenue generated from selling SRECs over a period of time may be factored into the calculated levelized cost of energy. One of skill in the art will recognize that other forms of renewable energy credits may be acquired via energy produced by the solar energy system, such as but not limited to, Verified Carbon Units (VCUs).
In an embodiment, the summary results of the solar energy simulation and energy production analysis may be presented to a user of the marketplace in a comparison table. The offerings may be compared to average conventional electricity costs without solar, based on the estimated rate of energy inflation. This may inform a user of the savings achieved by installing a solar energy system. A user of the marketplace may also manually enter the amount of their average monthly electricity bill and their conventional electricity provider to re-compute comparison data.
According to an embodiment, conventional electricity information presented to the user may include the average estimated monthly electricity bill during a period of time, e.g., the average monthly bill over the course of the next 25 years if a solar energy system is not installed, based on the estimated energy inflation rate. The expected annual energy inflation rate for a region may also be presented, which may be estimated through historical data retrieved from an external third-party, such as the Energy Information Administration. Information presented may additionally include the total cost of electricity during a period of time, e.g., during the next 25 years, based on current conventional electricity bills and estimated energy inflation rates.
Each solar energy offering may be compared against the option of using only conventional electricity (e.g., not installing solar) or against another competitive offering. Each offering, for example, may display metrics unique to the offering, such as but not limited to, the new estimated monthly energy bill, the monthly savings compared to conventional electricity, the total savings compared to conventional electricity during a period of time, e.g., during a 25 year period or during the term of a lease or PPA, and the amount of initial cash outlay required to install the solar energy system.
Additional details of the offering may also be presented, such as but not limited to, the financing company (if any), the equipment type, the origin of the equipment, the installer, and the time frame of a promotion.
As depicted in
These alterations and customizations may generate new offering results. Once the modifications are made and new results are produced, the details and or summary of the offering may then be compared with other offerings and with the conventional electricity (e.g., “without solar”) option. In an embodiment, information on monthly payments, the payback period and rate, monthly savings, incentives, carbon reduction and other factors may be presented. In an embodiment, a partial list of details for the initial offerings and customized offerings that are presented to a user may include, but are not limited to: The average price of a kWh of conventional electricity for the property over the next 25 years (e.g., the life of a solar panel) or another period of time, average monthly payments for conventional electricity, the estimated annual increase in conventional electricity rates, the average cost of a kWh of solar electricity produced by the solar panels over the 25 year life of the panels accounting for degradation and other factors, average monthly financing payments for the solar energy system, the annual increase of solar energy costs (e.g., in the case of a lease with an escalator clause), the total cost of the solar energy system (including financing charges, if any), the down payment due on a lease or loan, the term of a loan, the interest rate of a loan, the percentage of the electricity bill offset by solar energy, the total monthly payments during a period of time (e.g., solar and conventional utility costs combined), the total savings for the offering as compared against conventional electricity costs, the total electricity costs over the 25 year life of the solar panels or the term of a lease or PPA (e.g., solar and conventional utility costs combined), payments due over the life of the solar energy system, such as upfront payments, loan payments and lease payments, applicable national, state, local and rate-payer incentives, such as rebates, tax credits and performance-based incentives, and the installed cost as described above with respect to
The system size/capacity (nominal system power) in kW and energy production over a period of time (e.g., 25 years) in kWh or MWh may also be presented. In an embodiment, carbon pollution offset by the solar energy system, shown in barrels of tons of coal, or another metric, may additionally be presented. The effect of solar energy in offsetting carbon dioxide equivalent emissions may be equated to, for example, the number of new trees that would need to be planted, aluminum cans that would need to be recycled, miles of air travel offset, or miles of car travel offset for comparison purposes. In various embodiments, these details may be presented as lists, tables, graphs, or any combination thereof.
In an embodiment, the online solar marketplace may include several user types, such as but not limited to, system administrators 502, public administrators 504, property owners 506, sales agents 508, solar providers 510, and referral partners and sponsors 516. Public administrators 504 may include, for example, permitting administrators and interconnection authorities. Sales agent 508 may include, for example, remote sales agents and field sales agents. Installation providers 510, equipment providers 512, and financing providers 514 may provide various installation, equipment, and financing offerings to the marketplace that may be used to perform solar energy simulations, as described previously.
In various embodiments, users may initiate and participate in dialogues within the marketplace, share documents, and link to documents and messaging systems outside the marketplace, including affixing electronic signatures on documents to close sales in the marketplace. In an embodiment, threaded dialogues may be maintained.
Alerts and notifications may also be generated by activities of other users or changes to a simulation. In an embodiment, relevant parties may be automatically notified through electronic communications when appropriate based on a user's actions, or through specific input requests. Aggregated information related to user behavior may also be collected for analytic purposes.
Once a system is commissioned, the solar panels and other appliances may be attached to communicate data to the online solar marketplace to inform installers, sales agents and property owners on their working condition, and to compare performance with other users and connected systems. The marketplace may implement various performance monitors 518 to track performance of each installed solar energy system.
In an embodiment, the estimated carbon equivalent (CO2e) reduction 520 attributed to a solar energy offering may be calculated based on each simulation. This estimate may be used by property owners when selecting an offering, or by sponsors to evaluate carbon reduction efforts.
The marketplace may estimate the amount of CO2e reduction for a particular solar energy offering based on the total amount of energy produced over a period of time. For example, a 10 kW solar energy system at a particular geolocation may produce approximately 100,000 kWh of energy over 10 years. The estimated energy production may be derived from one or more simulations run for the 10 kW system.
In an embodiment, the geolocation of the solar energy system may be mapped to state and/or county Federal Information Processing Standard (MPS) codes. These codes may then be correlated to data in a carbon footprinting database that contains emissions data for particular geographic regions. The estimated energy output of the solar energy system may be converted to an amount of CO2e offset based on data retrieved from the carbon footprinting database. For example, the Environmental Protection Agency maintains an Emissions & Generation. Resource Integrated Database (eGRID), which contains emissions and energy conversion information for particular geographic regions. In an embodiment, a FIPS code mapped from the geolocation of the solar energy system may be correlated to a region defined by eGRID. The estimated solar energy output (e.g., 100,000 kWh) may then be converted into metric tons of CO2e using conversion information retrieved from eGRID. This allows the marketplace to present an estimate of the CO2e reduction that will be produced by installing a solar energy system at a particular geolocation.
Display 662 in device 660 three panels or areas 662, 664, and 666. Panel 662 provides a display area for a map display of a particular property being simulated in the online solar marketplace for a solar installation offering. Panel 664 includes display simulation results in several ways according to a feature. First a current average electrical bill value is displayed alongside a slider for enabling a user to change the value over a range of values by moving the slider setting. Three areas for displaying data relating to Money (value of energy, total incentives), Power (system size, electric usage offset), and Love (carbon reduction equivalent in CO2 lbs and miles driven in a car). A navigation bar 666 allows further navigation to a different window.
Graph 740 shows a bar graph plot of the payback years for a normalized number of property simulations in a West Virginia (WV) region. Graph 740 shows a mean payback year of 14.54 years (from time of installation to time when all installation costs equal energy cost savings) when installation cost is $4.00/watt). Graph 750 shows the plot of the payback years for the same normalized number of property simulations of graph 740 when the cost installation is $4.50/Watt which lengthens the mean payback year to 17.68 years in the WV region. Graph 760 is a line graph plot that shows the total amount of gigawatts likely to be viably installed for the region properties as a function of cost per watt (CPW) which accounts for installation costs. In this example, the installed amount drops at a greater rate for costs per Watt over $2.50, which indicates one optimal price may be $2.50/Watt.
At step 804, available equipment, installation, and financing offerings may be retrieved from a marketplace repository, such as marketplace repository 940 of
At step 806, an integrated solar energy offering for the property is generated based on the retrieved equipment, installation, and financing offerings. This offering may be assembled taking into account characteristics of the property and authorized combinations of equipment, installation, and financing, as described with respect to
At step 808, a solar energy simulation may be performed for the solar energy offering in order to estimate solar energy production over a given time period. For example, it may be useful to estimate solar energy production during the next 25 years, as this time period may represent the expected life of solar modules in the solar array. In an embodiment, multiple simulations may be performed by altering one or more parameters of the simulation, as described with respect to
At step 810, the solar energy offering and simulation results, such as energy production estimates, may be presented to the user. In an embodiment, the solar energy offering may be compared to conventional electricity options so that the user may directly compare the value of the solar energy offering. In an embodiment, the presentation of results may be constructed at a server, such as server 1010 of
In an embodiment, the solar energy offering may be modified, or new offerings may be created, based on results of additional simulations and energy production analysis. As illustrated in
Broad market simulations may be generated by running simulations on a plurality of properties within a particular geographic or geopolitical region and may be used in a number of ways. For example, in an embodiment, the online solar marketplace may enable users to rank and sort properties within a region, or rank and sort regions, according to solar energy capacity. These rankings may be adjusted based on determined propensities to adopt solar energy in order to rank and sort property owners and populations according to overall solar market opportunity. In an embodiment, the propensity to adopt solar may be determined by, for example, credit scores, consumer behavior, consumer demographics, political views, and real estate values.
At step 906, the individual properties within the region may be ranked according to the selected metric. At step 908, the rankings may be adjusted based on determined propensities to adopt solar energy at each property in order to rank properties according to highest solar energy conversion potential.
In addition to ranking and analyzing individual properties within a region, geopolitical regions, such as zip codes, municipalities, counties, states, and countries, may be analyzed to determine solar capacity and solar adoption propensity through a sampling or census of individual properties.
In an embodiment, the LCOE may be first characterized for each property within the sample or census based on atmospherics, shadow, slope and orientation. The cost of solar may then be characterized for each property based on conventional electricity rates, load profiles, utility inflation rates and available incentives, compared with LCOE in the region. A demonstrative solar site may be placed in the region, the specifics of which (e.g., size) may be based upon common or notional solar buyer behavior. In an embodiment, economic metrics may be determined and selected through economic modeling performed on each property. Economic metrics may include, but are not limited to, specific site performance measures (e.g., IRR), or measures which aggregate for all sites in a region, for example but not limited to, system savings multiplied by the number of potential residential or business sites. Regions may be ranked and sorted based upon the selected metric, such as an aggregate IRR for each property within the sample or census. Elements of the simulations on individual properties may be modified to determine the total addressable market under various scenarios. For example, simulations may be run with different incentives, utility rates, and/or financing options.

Marketplace repository 1040 may be any type of structured data store, including a relational or document-oriented database, such as an SQL-compatible database.
Marketplace repository 1040 may store data in a plurality of different data tables 1044A, B, etc. To improve performance of database queries and updates, marketplace repository 1040 may also include an index table 1042. In an embodiment, update module 1022 queries index table 1042 to assist with data insertions and updates, and query module 1020 queries index table 1042 to assist with data retrieval. In an embodiment, the index table 1042 may point to entries in data tables 1044, which include complete data records. Or, in an embodiment where the database is de-normalized, the index table may itself include individual data records in part or in full. In this way, index table 1042 may be used to improve performance of database queries and updates.
In an embodiment, data in geomatics repository 1030 and marketplace repository 1040 may be accessed via an application programming interface (API). In this manner, the API may allow third party applications to, for example, analyze simulation data and monitor performance of solar energy systems.
