Texas Solar Data by City

Your TDU determines the delivery charges on your electricity bill — fixed costs that remain regardless of solar generation. GetSunScore city pages model avoided-cost savings modeled against publicly available residential retail rate benchmarks (EIA 2024 reference year), while accounting for delivery charge structures that remain post-installation. Understanding which TDU serves your address is a necessary first step in accurate solar savings modeling.

The Texas city index covers cities across all four major TDU territories: Oncor, CenterPoint, AEP Texas, and TNMP. Each published city page reflects publicly available 2024 reference data for that city's service area. The index is expanding progressively. Zip-code-level modeling detail is available within individual city pages where applicable.

The federal Residential Clean Energy Credit (ITC) allows eligible homeowners to claim a tax credit equal to 30% of qualifying solar installation costs under current federal law (2024 reference year). GetSunScore city pages include this incentive as a modeled scenario input — it is not a guarantee of eligibility or savings. Homeowners should consult a qualified tax professional regarding their individual eligibility.

TDU territory is the most structurally relevant organizing framework for solar savings modeling in Texas. Delivery charges, interconnection timelines, and avoided-cost structures vary by TDU. An alphabetical index would obscure these differences. Organizing by territory allows city pages to provide more contextually accurate modeling rather than generic projections.
