How To Choose the Best Solar Company in San Antonio

The price and effectiveness of solar panels often rely on which company mounted them. Here are some key items to consider while searching for a solar installer.

Licensing and Training

All solar energy companies 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. You should also visit a company's website to learn about its private accreditations. Two of the most recognized are the Solar Heating Installer and PV Installation Professional certificates, backed by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in San Antonio

The kind of solar panels you purchase determines how much power you can produce. Monocrystalline panels and high-quality and cost more but give you the best performance. Polycrystalline panels produce less power, but they're worth it if you want a traditional panel style without the high cost. Thin-film panels aren't recommended for large residential installations, but they are ideal for small projects like converting RVs and sheds.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total installation cost, but they can boost your solar system's performance. Not all solar companies provide these optional components, so look for a contractor that installs them if it's a priority for you.

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

Solar Panel CostAverage 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 best financing solution will influence your overall solar system cost and potential savings. Common payment options include power purchase agreements, cash payments, loans, and leases. Though it involves a large up-front payment, cash is the most economical choice because it doesn't accrue interest and qualifies you for incentives. Solar loans are the next best option. As with a home or auto loan, you'll pay a monthly rate towards system ownership, including interest. You can still apply for cost-saving solar incentives, and depending on your lender, you could put 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 specific circumstances. Ask each business you're evaluating about the payment plans it offers. A consultant can help you determine the best option for your financial situation.

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

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