Factors that Affect Solar Panel Costs in San Antonio

Cost is often one of the most important factors for homeowners wanting to invest in solar. There are a few key factors that affect your total cost in San Antonio: solar equipment and system size, financing options and the solar installation company you choose. We'll discuss each of these briefly below.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the main factors is the system size, which is measured in kilowatts (kW). Solar power systems with higher efficiency or power generation need 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. The model of solar panels and equipment you get is another factor that will greatly influence costs. Solar panels that are more efficient, like monocrystalline panels, tend to be more costly. Furthermore, solar equipment goes beyond just the solar panels themselves. You'll also need to make decisions about the kind of racks used to mount the panels, inverters, solar batteries, etc. It's important to take all of this into consideration when searching for a solar system that falls within your budget.

Solar Financing Terms

For some homeowners, paying for solar out of pocket can be financially overwhelming. Solar loans are provided by most installers in San Antonio, which can bring down, or in some cases eliminate, your upfront costs to make solar more affordable. Even though solar loans make adopting solar energy more accessible for San Antonio homeowners, they can also raise the total you pay for your system due to interest. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

The solar company you hire to handle your switch to clean energy can play a part in your total costs. There are about 3 solar panel companies operating in San Antonio, and each can charge varying amounts for labor and equipment. Companies that only sell high-quality, high-efficiency and high-price products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It's best to do some research and go with the company that has the products, warranties and services you want and also fit into your budget.

How to Save on Solar Panels

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you decide on the right company for you, here are some tips to keep in mind:

  • Installation Process: Get detailed information from your solar company about the installation process and what to expect, such as when the site survey will be done and what the project timeline is.
  • Solar Panel Brands: The brand of solar panel you'd like to get plays a part in which company you should choose, since different companies offer different panels.
  • Contract: It's important to read your solar installer's contract well to understand what services they will provide, what the warranty covers and what you can expect about the project timeline.
  • Warranty: A quality company rises above other companies by offering the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.

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 exactly, because the cost depends on a variety of 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 cost more if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy needs. On the flip side, you can spend less if you go with a smaller solar panel system or less efficient solar panels.

Is it better to lease or buy solar panels in San Antonio?

Leasing solar panels can be an attractive choice, because it often comes with low or $0 upfront payments. The downside is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any tax rebates and credits and your home value won't increase. Buying solar panels is a better way to go if you want to get the most savings.

How will having solar panels impact my property value?

Solar panels can increase your property's value considerably as long as you buy or finance your panels and don't opt for a solar lease or power purchase agreement (PPA). According to research done by Zillow, the average home value increases by about 4.1% after installing solar panels."

How often do you have to replace solar panels?

Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can decide to replace them once you've had them for that long or you can keep using them at a lower efficiency.
