Benefits of Solar Energy

Solar energy comes with multiple benefits. Let's look at a few of them.

  • Reduced carbon footprint: Solar is a highly abundant clean energy source, meaning you can reduce or eliminate your home's dependence on non-renewable sources.
  • Lowered energy bills: You can skip the premium cost of grid-tied power by generating some electricity right where you use it.
  • Better energy independence: Solar systems with energy storage operate through power outages and emergencies, and you won't have to rely on the electrical grid for your safety and comfort.

How To Choose the Best Solar Company in San Antonio

Choosing a company is the first step toward a well-oiled and valuable solar system. Make your choice based on the following vital factors.

Licensing and Training

All solar installers 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. Look for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), one of the solar sector's most credible trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in San Antonio

The kind of solar panels you select dictates how much electricity you can produce. Monocrystalline panels give you the best performance but cost more upfront. Polycrystalline panels work with a tried-and-true mechanism and cost less, but produce less power. Thin-film panels aren't recommended for large residential installations, but they are ideal for small projects like converting RVs and sheds.

Additional accessories, such as battery storage and electric vehicle (EV) chargers, will raise your overall costs. However, they might make your solar system more efficient and convenient to use. Not all solar providers offer these add-ons, so look for a company that installs them if it's essential for you.

A majority of San Antonio homeowners choose solar systems designed for five kilowatts (kW) of electrical capacity. These systems run about $16,650 to set up, considering both parts and installation. You can find more specific cost information in the table.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,006
Solar Polycrystalline $785
Thin-Film $459
Solar Battery $644
Solar Home EV Charger $2,415

Financing Solar Energy in San Antonio

Choosing the ideal financing option will affect your overall solar system cost and potential savings. Common payment options include leases, cash payments, loans, and power purchase agreements. 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. Much like a car or home loan, you'll pay a set monthly rate with potentially $0 down. Solar leases allow you to pay a monthly rate to rent your panels, while a power purchase agreement lets you pay a fluctuating rate based on only the energy you use. We generally advise against these options since you will not have ownership of your system and are disqualified from solar incentives, but they might be appropriate in particular circumstances. We advise working with an installer that offers multiple financing options. Talk to each agent about what's available, and secure more than one estimate for the best odds of staying within your financial plan.

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

You are eligible for a 26% federal tax credit for new solar power systems until the year 2032. City and state officials 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 San Antonio

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

Most San Antonio homeowners spend about $1,405 on energy each year. Your costs could drop by $992.28 for each kilowatt you generate after you pay off a solar array.

How popular is solar energy in San Antonio?

Yes, solar energy is spreading quickly in San Antonio. Some homes already benefit from solar power on-site or through utility grids, and they're backed by a state solar economy with 10261 jobs and counting.

Will solar panels raise my San Antonio home value?

Yes, a solar PV system will increase your property value. According to the National Renewable Energy Laboratory, 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.

What if I live in a heavily-wooded or dark

Solar panels could still work in cloudy conditions. Your provider will orient your panels to capture the most sunlight possible. They might also recommend a backup battery to keep your system performing at its best.

How long is a San Antonio solar panel's average lifespan?

Today's solar installations are incredibly durable, lasting up to 25 years. Monocrystalline panels and other high-end models tend to last longer than cheaper models.

What size should my new San Antonio solar system be?

A typical San Antonio solar home has a 7.5-kW panel array, but you might need a bigger system if your energy needs are more demanding. Solar installers will evaluate your property's power usage and roof shading to suggest the proper system for you.

What are some "red flags" to watch for as I research companies?

Even the most respected San Antonio solar companies will have both supportive and critical reviews. To make the most informed selection possible, focus on these indicators to know if a company isn't worth your time:
  • Aggressive sales pitch
  • Dodging questions about cost, references, training and credentials and warranties
  • "One-size-fits-all" approach
  • Not thoroughly inspecting your site
  • No business filing with your local secretary of state

What's the difference between a PPA and a solar lease?

Choosing a leasing option means your solar installer will handle panel maintenance while you make fixed monthly payments. PPAs differ slightly because you pay based on the electricity you produce.

You don't own the panels with either option, though you can choose to "buy out" of the contract for a fee.
