Solar Energy Glossary
Definitions to help interpret solar production, electricity bills, and modeled estimates.
These terms provide context for Texas solar estimates; not every term is a direct calculator input. This glossary is educational, not financial or tax advice. For the current inputs and their dates, see the methodology and data sources.
Understanding these terms supports transparency in how GetSunScore constructs non-binding savings scenarios for residential solar assessment. Readers are encouraged to consult the /methodology page for a full explanation of modeling assumptions.

How Glossary Terms Are Used in
Texas Solar Estimates
Irradiation Layer
Solar Irradiance and Peak Sun Hours explain the sunlight resource. Current city production inputs are committed NREL PVWatts reference yields; they are not roof-specific measurements.
Utility Rate Layer
Utility Rate Structure and Avoided Cost help explain the value of self-used solar. The calculator uses a Texas statewide electricity-rate baseline, not a household REP contract or exact TDU charges. Net Metering and Buyback Plan terms explain why actual export credits can differ.
Incentive Layer
No incentive is automatically applied in current estimates. The federal residential clean energy credit ended for expenditures after December 31, 2025 under current IRS guidance. See current incentive status for details; eligibility for any other program must be checked separately.
20-Year Projection Modeling
The calculator applies scenario assumptions for panel degradation and electricity-rate escalation to estimate savings and payback ranges. Grid Parity and LCOE are explanatory comparison concepts, not additional outputs calculated for each visitor.
Current estimates use versioned PVWatts city yields, an EIA Texas electricity-rate baseline, and documented scenario assumptions. They do not model a household's exact retail plan, roof, or tax eligibility. See methodology for source dates and limits. GetSunScore does not install solar systems, provide financial advice, or guarantee savings.
