How Much Can Solar Panels Save You in Killeen, Texas?
Finding out how much you can save on solar in Texas, is not a straightforward answer. It depends on several factors, including the solar billing of your utility company, the size of a potential solar system on your roof, and your household’s energy consumption. While most solar installers will try to cover all your electricity needs, the actual savings will depend on your home’s unique conditions. To get a personal estimate of how much you could potentially save by going solar, fill out a simple form on our website, use Google’s Project Sunroof solar savings calculator, or consult with a couple of local solar installation companies for a personalized savings calculation.

Solar Financing Explained
You can pay for solar panels in a couple of ways:
- Cash
- Installer solar loans
- Personal loans
- Cash-out refinance or HELOC
- Solar Leases or Power Purchase Agreements (PPA)
First, there is a cash purchase, which in most cases provides the best price and long-term savings, but the upfront payment is not always what you can afford. If you want to own your solar panels and don’t have about $15,000 to $20,000 in the bank, you’ll have to choose solar panel financing.
You can consider a personal loan, a home equity line of credit, or a solar loan offered by the solar company. However, keep in mind that these loans come with interest and additional fees. Solar loans often are tied to dealer fees, which can increase the total cost of your solar system by 20% or more in exchange for a lower interest rate. To ensure you get the best possible deal, it is wise to compare the dealer fees and interest rates offered by different installers. This way, you can make an informed decision based on the most favorable terms available.
Some companies offer solar leases or PPAs that require zero upfront cost. But in such cases, you don’t own solar panels and you are not eligible for any solar rebates or the federal tax credit. And, because you have to pay the solar company monthly, your total solar savings will be lower. Ask for detailed savings calculations from a solar installer to decide on the best option. In most cases, you will still be paying less for electricity.

Texas Solar Incentives and Rebates
Solar in Texas is kind of a mixed bag when it comes to incentives. The state doesn't really step up with much, but you've got the federal credit doing most of the work, plus some local utility programs that can really help—if you happen to live in the right area. Let me walk you through what's out there.
1. Federal Solar Investment Tax Credit (ITC)
URGENT UPDATE: This credit expires December 31, 2025. You must have your system installed and operational by year-end to claim it.
This is where most of your savings come from in Texas. The feds give you 30% back on everything—panels, inverters, installation, the whole nine yards.
Right now, a typical 7 kW system in Texas is going for around $19,600 (that's October 2025 pricing). Take 30% off and you're down to about $13,720 out of pocket. You're saving close to $6,000 just from this one credit.
Same story everywhere: you've got to own the system—cash or financing, doesn't matter. Leases don't count. And you need enough federal tax liability to actually use it. If you don't owe enough in one year, it rolls over to the next.
The catch: The "One Big Beautiful Bill" signed in July 2025 ended this credit effective January 1, 2026. There's no phase-down, no extension—if you don't install by December 31, 2025, you're paying full price. Solar installations typically take 2–4 months from contract to completion, so if you're reading this in late 2025, you need to move fast.
2. Texas Solar Property Tax Exemption
This is honestly one of the better things Texas does for solar, and people don't always appreciate how much it matters. The state exempts solar systems from property tax assessment, and it applies everywhere in Texas.
Solar panels boost your home's value, sometimes substantially. Normally, that means higher property taxes, but Texas says you don't pay extra property tax on whatever value the solar adds.
Here's the thing: Texas property taxes are already pretty brutal—some of the highest in the nation. So, dodging that annual increase year after year? That's real money. Not as exciting as getting a big rebate check, but over 25 years, it adds up to thousands of dollars.
3. Local Utility Rebates
Alright, this is where it gets messy. Some Texas utilities offer solar rebates, some don't, and the ones that do can have wildly different programs. Plus, they change all the time, and funding runs out. Here's what's been available:
- AEP's SMART Source Solar PV Program: If you're in American Electric Power's territory, they've offered rebates from $1,500 to $3,000 depending on system size. Worth checking if they still have money available.
- Austin Energy: Austin's had a $2,500 rebate for systems 3 kW or larger, but you've got to take their solar education course first. Their program's pretty popular, which means funding can disappear fast. Definitely verify it's still active before you count on it.
- New Braunfels Utilities: They've done rebates up to $3,000 for systems at least 3 kW, with the amount varying based on size and panel angle. Check current availability.
- Oncor: They've run a program for systems between 3–15 kW paired with battery storage. Battery requirements are becoming more common with utility programs.
My advice on utility rebates: confirm directly with your utility that they're active and taking applications before counting on them. These programs appear, disappear, run out of money, change requirements—they're unreliable. If you get one, great. If not, you need to make sure solar still works for you without it.
What About Net Metering?
This is where Texas really drops the ball. There's no statewide net metering policy, which is pretty unusual. Some utilities offer it, many don't, and the ones that do often give you terrible rates.
What this means in practice: a lot of times in Texas, that excess power your panels produce during the day doesn't get credited back to you at full value. Some utilities buy it at wholesale rates (way less than you pay), and some won't buy it at all. It's honestly one of the weakest parts of going solar here.
The upside? Texas gets absolutely blasted with sun. And electricity rates have been climbing—deregulation means it's all over the place, but a lot of folks are paying pretty high rates. So even without good net metering policies, solar can still make financial sense.
What You're Actually Looking At
Let's say you're in an area without any utility rebates, which is pretty common. You're working with that 30% federal credit and the property tax exemption—but only if you act before the end of 2025.
That $19,600 system costs you about $13,720 after the federal credit. If you happen to be in an area with a utility rebate and can snag one, knock off another $1,500 to $3,000.
Starting January 1, 2026, that same system costs you the full $19,600 with no federal help.
Texas electricity rates are kind of all over the map—it depends on your provider, your plan, and where you live. If you're stuck with high rates, your payback might hit around 10–13 years with the current incentive. Cheaper electricity? Could stretch out to 15–18 years. Without the federal credit, add another 4–5 years to those timelines.
The lack of decent net metering stings, but Texas has killer solar production potential. West Texas, South Texas—those areas get incredible sun. Even in Houston with all the humidity and clouds, you can still pull good numbers. That strong production helps make up for the less favorable policies.
Just remember that federal credit only helps if you're paying federal taxes. If your tax bill is small, you won't get the full benefit right away. It does carry forward, but it's something to think about. Probably smart to run through your specific tax situation with your installer or an accountant before you sign anything.
Bottom line: If you're serious about solar in Texas, the deadline is December 31, 2025. After that, you're looking at significantly higher costs and longer payback periods.

How We Classify Solar Installers: What Matters Most?
What to Look for In a Solar Company
To ensure that you partner with a great provider that can meet your needs of going solar, look for the following:
- Make sure the solar installer has industry-standard certifications, such as those from the North American Board of Certified Energy Practitioners (NABCEP), indicating that they meet the gold standard in renewable energy installations. Also, verify if they are licensed, bonded, and insured for residential solar projects in your area. If subcontractors are involved, check their credentials as well.
- Prioritize installers with a proven track record in solar installations, ideally with at least 5+ years of experience. Ask about the number of systems they’ve installed and their project portfolio. A competent installer should openly discuss the solar panels, inverters, and batteries they use if they help to take advantage of local solar incentives and rebates, and warranty coverage specifics.
- Your installer should be forthcoming about the installation process and answer any questions you might have, like “How many solar panels will I need? Why?”, “Can you give me a detailed cost breakdown based on my energy consumption?”, “What solar panel brands do you install? Why?”, etc.. They should also be transparent about their use of subcontractors, detailing their roles and how their work will be supervised.
- A preliminary evaluation of your roof’s condition is the groundwork. The installer should advise on necessary repairs to ensure it’s ready for solar panel installation and clarify responsibilities for any potential roof damage during the process. Discuss aesthetic concerns, such as the placement of solar panels around roof vents or the possibility of relocating vents for a more visually appealing setup.
- Check the installer’s reputation through online reviews and testimonials. They should be able to connect you with past customers willing to share their experiences. Personal recommendations from friends or neighbors who’ve gone solar can also be invaluable.
- Solar installation costs can vary widely, so obtaining multiple quotes is advisable. Experienced installers will adjust their offers to your home’s specifics—size, energy needs, etc. For an objective cost comparison, calculate the price per watt of the proposed system, giving you a standardized basis to evaluate different quotes.
Should You Choose a Local Solar Installer or a Big National Company?
Always choose a local solar company over a big national corporation. Small local companies that operate in a distinct local area are better than multi-state and national solar companies and large corporations. It’s the small local companies who get the best reviews on our website, and it’s the national multistate companies who get very poor reviews. Why so, you may ask?
Solar is a local service business, for the most part, and it is extremely difficult to run a solar company and offer good customer service to many locations from a central office.
Local ones have a community connection, they know better the incentives and regulations in the area, and they simply care more about you than large businesses trying to get into your pocket and overprice you. While multi-state solar companies might try to convince you by financial stability and “quality of installations across different locations”, try to choose a local company that meets all your criteria.
What Does a Solar Installation in Killeen, Texas Look Like?
Here’s how a solar system installation will look like once the design for your solar system is approved:
- First, a solar installer should estimate your energy needs and analyze your annual and monthly electricity consumption, which you can find on utility bills measured in kilowatt-hours (kWh). Such calculations will help you understand potential savings, the payback period, and the system size you need.
- A home energy audit is something every experienced solar company would do to understand the size and output needed.
- Next question on the list: are your house’s roof conditions good enough for installation? A solar installer should carefully inspect the roof and ensure its conditions and orientation are good to go, how and where to better place solar panels and wire the system.
- Next, they will design the system and show you how it’s going to look.
- You will usually need a permit to install solar panels from your local authorities, and the solar provider should handle all the paperwork.
- The entire process might take up to 3 months depending on the state and local regulations, while the system installation is usually up to 3 days (might take longer depending on roof conditions and system complexity).
- The installation crew should always clean up and remove any debris, leaving your house in good condition.
- When the system is installed, it should be checked and approved by local municipality inspection.
- If you’re connecting your system to the grid, it has to be wired to your local utility system. You’ll apply for connection through your utility company, which will also want to inspect your system to ensure it’s following utility guidelines. Some installers may help you with this step, so always ask. Once you have all the permits, your system will be up and running, powering your home with solar.
