Benefits of Solar Energy

Solar energy provides numerous advantages that will enhance your home for years to come.

  • Better energy independence: Solar panels can keep your home running through emergencies and blackouts, giving you additional security. You can use your solar energy anytime with optional battery storage.
  • Lowered energy bills: Solar panels allow you to generate your own energy to power your home, lowering your regular electricity costs. You can eliminate your bills completely if you go off-grid.
  • Reduced carbon footprint: The sun is the universe's most abundant clean energy source, meaning you can reduce or eliminate your home's dependence on "traditional" sources.

How To Choose the Best Solar Company in Killeen

The price and efficacy of solar panels often rely on the solar company that installed them. Here are some crucial criteria to remember while searching for a solar company.

Licensing and Training

All solar contractors in Texas must have a state electrical contractors' license from the Texas Department of Licensing and Regulation. The Texas State Board of Plumbing Examiners regulates plumbing regulations and licensing standards for solar thermal installers. Check for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), one of the solar industry's most respected trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Killeen

Different solar panel types look and perform differently. Monocrystalline panels cost more than other options, but they generate the most power. Polycrystalline panels provide a lower price point but produce less power. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total project price, but they can improve your solar system's performance. Not all solar companies include these add-ons, so look for a contractor that sells them if it's essential for you.

Generally speaking, it costs about $16,650 for a five-kilowatt solar array in Killeen. This table lists more specific costs for different solar panel types and system components in your area.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,083
Solar Polycrystalline $845
Thin-Film $494
Solar Battery $693
Solar Home EV Charger $2,600

Financing Solar Energy in Killeen

Choosing the correct financing solution will impact your overall solar system cost and potential savings. Common payment options include leases, power purchase agreements, cash payments, and loans. Most solar experts recommend a cash payment or using a solar loan. Cash payments demand a large up-front sum, but they help you avoid paying interest, grant you system ownership, and qualify you for cost-saving incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Like a home or car loan, you'll pay a set monthly rate with as little as $0 down. Solar leases allow you to pay a monthly fee to rent your panels, while a PPA lets you pay a variable rate based on only the energy you use. We generally don't recommend these options since you will not have ownership of your system and are disqualified from solar incentives, but they might be suitable in certain circumstances. Ask each company you're vetting about the payment options it offers. A consultant can help you determine the best option for your budget.

The table below lists the average payback periods for different capacities of solar systems in Killeen.

You are eligible for a 26% federal tax credit for new solar energy equipment until the year 2032. Municipal and state governments and utility companies might also offer discounts, rebates, and specialized financing options that could save you more.

Solar System Capacity Estimated Payback period
1 kW 2.1 years
2 kW 4.2 years
5 kW 10.6 years
10 kW 21.2 years

Frequently Asked Questions About Solar in Killeen

How much energy and money could I save per year by switching to solar?

Most Killeen homeowners spend about $1,433 on energy each year. Your costs could drop by $901.42 for each kilowatt you generate after you pay off a solar array.

How widespread is solar energy in Killeen?

Yes, solar energy is on the rise in Killeen. Some homes already benefit from solar power on-site or through utility grids, and they're supported by a state solar economy with 10261 job opportunities and counting.

Will solar energy systems raise my Killeen home price?

Yes, solar energy systems will raise your property value. According to the National Renewable Energy Laboratory (NREL), for every dollar you reduce on energy bills, your home value increases by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

Is solar installation a fast job?

There's no universal answer for how long a solar project might take. Ultimately, it depends on local weather, the necessary prework, system size, the permitting and inspection process, and panel style. Many homeowners can be solar-ready within a few months from their initial estimate visit.

What size should my new Killeen solar system be?

The average Killeen solar system size is 7.5 kilowatts (kW). However, your final system size depends on your home's energy needs. Your panel model, surrounding shading, and roof size could also impact your final result. A professional solar provider will consider these factors and determine the right array size for your home.

What is the average payback period for Killeen solar panels?

The average payback period for a solar loan in Killeen is 12.9 years. By paying off extra principal each month, you can shorten the payback period and own your system faster.

What's the difference between a PPA and traditional financing?

The main differences between a power purchase agreement and traditional financing are that you pay a fluctuating monthly rate based on your energy usage and don't own your system. Your service provider installs and maintains the panels, and you pay for the generated electricity for 10–25 years. Afterward, you can continue the contract or buy the system.

You might think about a PPA if you don’t want to be responsible for maintaining your panels and don’t want to invest in a system, but keep in mind you won’t be paying toward ownership or be able to access any cost-saving solar incentives. Many solar experts don’t recommend PPAs. Our guide covers other payment options above.
