GetSunScore – Texas Solar
Savings Intelligence Platform
GetSunScore provides modeled solar savings projections based on publicly available datasets, including NREL irradiation benchmarks, EIA consumption data, and Texas utility rate filings. GetSunScore functions as a structured intelligence layer for analyzing solar economics across Texas utility territories.
All projections are non-binding estimates based on modeled scenarios. GetSunScore is not a solar installer and does not provide financial advice.
What Is the SunScore™ Projection Engine?
SunScore™ is GetSunScore's core analytical system for generating residential solar savings estimates. It synthesizes publicly available data from multiple authoritative sources to produce modeled 20-year savings projections for homeowners across Texas.
The engine does not collect proprietary utility data or personal energy bills. All inputs are drawn from publicly available datasets including NREL solar irradiation benchmarks, EIA regional consumption averages, IRS tax credit schedules, and Texas utility rate filings.
How the Model Works
SunScore™ operates on a layered assumption framework. At its foundation, it applies location-specific peak sun hour data from NREL's National Solar Radiation Database. This irradiation layer is combined with regional electricity rate data from public utility filings to model estimated annual energy offset potential.
The system then applies applicable incentive layers — including the Federal Investment Tax Credit and any relevant state-level programs — to produce a projected 20-year savings range.
All outputs are modeled scenarios, not guaranteed outcomes. Actual results will vary based on individual household consumption patterns, roof characteristics, system sizing, utility rate changes, and future policy adjustments.
Model Specification Context
Understanding the Texas Electricity Market
Texas operates under one of the most distinct electricity structures in the United States. The state's grid — managed by ERCOT, the Electric Reliability Council of Texas — functions as an independent system largely isolated from the broader national grid. This structure creates a uniquely competitive retail electricity environment that directly affects solar savings potential across the state.
Deregulation & Solar Analysis
Approximately 85% of Texas electricity customers operate within a deregulated retail market. This means residential customers in most metropolitan areas can choose from multiple retail electric providers (REPs), resulting in variable electricity rates that affect the economic modelling of solar adoption.
Because retail electricity rates differ significantly across REPs and contract structures, SunScore™ projections use publicly available rate benchmarks rather than real-time pricing.
Transmission & Distribution (TDUs)
The four primary TDUs serving Texas maintain distinct rate structures that form part of the analytical foundation for SunScore™ projections:

Read Our MethodologyHow GetSunScore Maintains Data Integrity
Data accuracy is not a one-time event — it requires an ongoing governance structure. GetSunScore operates under a quarterly data review protocol designed to ensure projection inputs remain consistent with publicly available reference data.
Quarterly Review Process
Each quarter, the platform undergoes a structured review of three core data layers: utility rate filings, incentive program status, and irradiation benchmarks.
Year-Labeled Data References
All rate and incentive references published on this platform include explicit year labeling, cited as "based on publicly available 2024 Texas utility filings."
Public Filing Sources
All inputs are derived from publicly available government and regulatory sources including NREL, EIA, IRS, DSIRE, and PUCT filings. No proprietary vendor data used.
State Layer
Texas-wide irradiation benchmarks, regulatory conditions, and incentive availability.
Utility Layer
segmented by TDU (Oncor, CenterPoint, AEP, TNMP) since structures differ meaningfully.
City Layer
Localized irradiation data and rate context applied for city-specific projections.
Incentive Layer
Federal and state programs modeled as separate variables for total transparency.
Solar Modeling Across Texas Utility Territories
GetSunScore organizes its analytical framework across four structured layers that reflect how solar economics actually vary across the state.
This four-layer structure ensures that every SunScore™ projection reflects the specific conditions relevant to a homeowner's location — rather than applying a uniform statewide average.
