The Texas Solar Energy Society does not endorse candidates or parties. This article summarizes publicly available information and is provided solely to help readers understand how federal policy decisions can affect solar energy development in Texas.
Why This Race Matters Beyond Pure Politics
On November 3, Texans will elect a U.S. Senator in a race featuring Republican Ken Paxton, Democrat James Talarico, and Libertarian Ted Brown.
Although energy policy may not dominate every election conversation, decisions made in Washington can have significant implications for Texas’ electricity market, and from federal tax incentives to energy infrastructure and domestic manufacturing, congressional decisions can influence how energy projects are financed, developed, and operated.
For homeowners considering rooftop solar, businesses evaluating new investments, and communities experiencing rapid energy development, understanding these policies is important regardless of political affiliation or who you’re voting for.
How the U.S. Senate Influences Solar
While much of Texas’ electricity market is governed at the state level, federal policies can influence the economics of solar development in several ways:
Tax policy. Federal tax credits have historically helped reduce the cost of solar installations. However, 2025 federal tax legislation ended the residential clean energy credit (Section 25D) for installations completed after December 31, 2025. It also accelerated deadlines for credits supporting larger wind and solar projects, although certain projects meeting construction requirements remain eligible beyond 2027. Future legislation could modify these provisions.
Federal spending and legislation. Congress determines how much money the federal government spends on energy, including money for energy research, for improving the energy infrastructure, and domestic manufacturing.
Committees and confirmations. Senators participate in committees addressing energy and tax policy while also confirming leadership at agencies such as the Department of Energy and the Federal Energy Regulatory Commission (FERC).
Investment certainty. Energy projects have substantial upfront capital requirements and lifetimes that span decades. Federal policy changes can affect financing decisions, project timelines, and longer-term investment planning.
What Each Outcome Could Mean
This race could help determine which party controls the Senate, and Democratic leaders have pledged to seek extensions of clean energy tax credits if they regain a congressional majority, while many Republicans support phasing them down. For rooftop solar, the key question is whether a future Congress revisits the expired residential credit. For utility-scale solar and manufacturing, remaining credit deadlines, trade policy, and permitting reform are what will matter most.
It is worth noting that solar has potential upside under either outcome, because the support for solar crosses party lines for various reasons. Many Republicans back solar on the grounds of private property rights, rural economic development, energy independence, domestic manufacturing, and grid reliability— in the Legislature, rural Republicans have joined Democrats to defeat measures that would have made it harder for solar to compete in ERCOT. Many Democrats back solar for emissions reductions, clean energy investment, and climate goals. In a market-focused policy environment, solar competes on cost in ERCOT’s merchant market; in an incentive-focused one, restored federal credits would lower financing costs, particularly for rooftop systems. Texans across the spectrum generally want affordable, reliable electricity, even when they differ on how to get it.
An important caveat to keep in mind is that no single Senator sets up policy. Outcomes will depend on which party controls each chamber, presidential action, and negotiations that cannot be predicted today. These are reasonable projections, not certainties.
What Probably Won’t Change
Regardless of who wins:
ERCOT’s electricity demand is growing faster than any other U.S. grid, driven by population growth, data centers, and industrial expansion
ERCOT’s own planning studies identify a need for large amounts of energy sources like solar, battery, and wind capacity to meet expected demand.
Solar is being built in Texas primarily on economics and speed of deployment: the U.S. Energy Information Administration expects roughly 40% of the nation’s 2026 solar additions to occur in Texas, where solar generation is projected to exceed coal generation for the first time this year.
Grid reliability will remain a priority across the political spectrum.
What Solar-Minded Texans Might Watch
For readers following the election with solar in mind, a few federal signals are worth tracking regardless of the winner:
The residential tax credit. Whether any future Congress revisits the expired Section 25D credit is the single biggest variable for rooftop solar and the one homeowners feel most directly.
Utility-scale credit timelines and guidance. The remaining deadlines and any new Treasury or IRS guidance on them shape the economics of large Texas projects and solar manufacturing.
Transmission policy. Rules like FERC Order No. 1920 determine how easily power from solar-rich West Texas reaches demand centers; transmission and permitting reform affects nearly every large project.
Trade and tariff policy. Tariffs on panels and components influence solar costs independently of the tax-credit debate.
Committee assignments and agency confirmations. Less visible than headline votes, these shape the technical rules that govern how projects get built and connected.
The Bottom Line
Federal elections can influence solar energy through legislation, investment incentives, regulatory decisions, and infrastructure priorities, but regardless of the outcome, Texas’ energy future will continue to depend on economic conditions, electricity demand, technological advancements, and decisions made at the state level.
Regardless of political affiliation, understanding how these factors interact helps Texans make informed decisions about the energy systems supporting their homes and communities.
