The Tx Solar Tax Credit is a topic of interest for homeowners, students, and researchers attempting to grasp the concept of solar return on investment in Texas. Although it appears to be a credit specific to Texas, it is generally a federal policy that has a profound effect on solar economics in Texas.  For anyone researching solar adoption or attempting to project the payback of a project, it is important to grasp the concept of this credit. 

How the Federal ITC Is Commonly Misunderstood as the Tax Credit

It is generally assumed that Texas provides its own solar tax credit. However, the “Tax Credit” is most likely a reference to the federal Investment Tax Credit (ITC) applied to solar in Texas. This is a common mistake, especially for first-time researchers.

Key clarifications include:

• Incentive provided by the federal government, not just by Texas.
• Policy is equally applied to all US residents.
• This is a federally income tax credit, not a state income tax credit.
• 3 Types of Solar: Residential, Commercial, Utility Scale
• Solar's cost will be used to calculate the federal incentive value at a specific percentage of the total cost.

Why the Federal ITC Has a Major Impact on Solar ROI in Texas

In Texas, the federal Investment Tax Credit (ITC) is a significant contributor to the affordability of solar energy. By reducing the overall installation costs to a very affordable amount, the ITC often provides enough capital to fund most of the initial investment in solar projects. The effect of the ITC allows project developers shorter payback periods and higher internal rates of return (IRR).

In addition to the ITC, Texas has an abundant supply of sunlight, which provides an opportunity for large-scale solar installations to be feasible throughout the state. Researchers and developers can maximize the use of strong federal incentives even though solar projects do not have direct support from the state government. In some cases, additional local incentives (e.g., rebate programs, net metering) may further improve a project's return on investment (ROI), however, these incentives vary from place to place, leading most researchers studying solar energy to highlight the importance of conducting data-driven analysis and a comprehensive site evaluation before finalizing any project design in Texas.

Final Thought

The Tx Solar Tax Credit is a way to express the application of the Federal ITC in Texas, not an additional state incentive. Once analysts have a solid understanding of how the interaction between Federal Credits and Texas's unique energy landscape works, they can develop more realistic ROI models that will also help explain why the use of Solar Power continues to grow in the state of Texas, despite the lack of added state incentives.
