Factors that Affect Solar Panel Costs in San Antonio

While the average cost of solar panels in San Antonio is $14,930, your final cost may be higher or lower than that. There are many factors that can have a major impact on the cost of a residential solar panel installation. Below are some of the more crucial things to take into consideration.

Solar Equipment Size

The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the key factors is the system size. Solar power systems with better efficiency or power generation use better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $2,690. There are many different solar panel brands and the one you choose also affects the cost. In many cases, the brands that are more efficient tend to also be more expensive. Plus, the type of equipment you're looking to install can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Solar panels can save you money on utility bills over time, but they can also be a big investment. That's why many San Antonio homeowners choose to finance their solar panel systems to offset upfront costs. It's a good idea to add the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it'll take to pay off the loan.

Solar Panel Installation Company

A final factor to keep in mind when trying to evaluate the cost of solar for your home or business in San Antonio is the company you hire to install your solar panel system. Similar to choosing a company to install new cabinets, for example, there's no shortage of solar installers that offer a range of services at different costs. The size of the company can sometimes play the most significant role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower prices due to access to more resources and better pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or discount can bring their pricing lower to compete with bigger names.

How to Save on Solar Panels

The solar panel company you opt for will be a major factor in determining not only your total costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are a few important things you should consider, including:

  • Warranty: A quality company stands out from other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
  • Contract: When reading over your solar installer's contract, ask for clarification about any terms you're not sure of and be sure you understand what happens in scenarios such as a system component breaking or if the company goes out of business.
  • Installation Process: Homeowners should make sure they understand how exactly the installation process will go, as well as important factors like the completion timeline.
  • Solar Panel Brands: The brand of solar panel you'd like to install plays a part in which company you should opt for, since different companies provide different panels.

EcoWatch's San Antonio, TX Solar Cost FAQs

How much does it cost to install solar panels in San Antonio?

This is a difficult question to answer precisely, because the cost depends on a few different factors. Generally speaking, it costs about $13,450 for a 5-kW system and $26,900 for a 10-kW system after the ITC is applied. It will be more expensive if you want additional solar equipment or higher quality panels, or if you have above-average energy usage. Conversely, you can spend less if you opt for a smaller solar panel system or less expensive solar panels.

Are solar panels free in San Antonio?

You can't get solar panels for free in San Antonio. However, you may still be able to get them on a lower budget. You can lease solar panels for a low upfront cost or, if you'd prefer to own your solar panels, you can finance them with a solar loan.

Can solar panels significantly reduce my energy bills?

Solar panels can potentially eliminate your electricity bills depending on where you're located and how much sunlight your home gets. Even if it doesn't get rid of them completely, you can save a lot of money on your bills, about $992.28 per year.

What solar power system size is right for my home?

To figure out how many solar panels you need, you should find out how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can generally produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
