Solar panel installation cost in San Antonio
The size of a solar panel system also plays a role in how much the installation will cost.
Larger solar installations will typically have a lower cost per watt, because the panels can be purchased at a ‘bulk price’. However, these larger solar systems will still have a higher total cost, because they are made up of more individual panels.

My husband and I have debated over Solar for a while. When I saw an add for American Sentry Solar. Brad came to the house armed with all the answers to our questions. We did not want to rent panels, we wanted to purchase them. Brad was able to help us out with a new roof and critter guards as we have a ton of squirrels. The crews that came out to install the roof and solar panels were fantastic! They were respectful of my property and the clean up was beyond compare.

Rudy and company did an amazing job. All the solar equipment was top of the line and they completed the work in a timely manner and all the equipment was installed in a very professional manner. Rudy promptly provided support whenever needed. When our local electrical utility technician arrived to replace our meter he commented on how well our equipment was installed. I would highly recommend Wright-Way Solar to friends and family.

I came across Solartime through EnergySage and went with them based on their pricing and professionalism. After they provided multiple proposals with various options and we discussed the pros/cons of each, I ended up deciding on an 8kW system using SMA Power Optimizers and REC 400W Alpha Pure Black panels. They were extremely helpful throughout the entire process; answering all of my various questions and proactively providing guidance on each next step of the process. The install itself was incredibly smooth, and I was generating power before I knew it. If I ever end up moving and needing another solar install in the area, I would absolutely contact Solartime first.

How much do solar systems using the most common brands of solar panels cost in San Antonio in 2022?
Where there is no specific pricing information available for a brand then we have used state pricing data for that brand.
Table 2: Local solar panel manufacturers
| Solar panel manufacturer | Avg. cost per watt |
|---|---|
| Canadian Solar | $2.65 |
| LG Solar | $2.85 |
| SunPower | $2.91 |
| Panasonic | $2.87 |
| LONGi Solar | $2.61 |
Why solar panel cost should not be your only consideration when buying solar panels for your home
The most important difference between buying solar panels and any other purchase is that solar panels last 25-30 years. This is a long, long time and you will need customer service over all that time. The reviews below of the two largest corporate solar installation companies indicate larger corporate solar companies are not delivering this support to their customers.
We recommend you find a small or mid-size, local, family-owned solar company. These companies tend to care more about you and your specific job. You don't want to be on hold to a corporation's call center for the next 25 years!
What other factors affect the cost of solar panels for your home?
The cost of solar doesn't just include the equipment and installation costs - it’s also made up of permitting costs, inspection costs, and installer profit margins.
These different components are what make the price of solar fluctuate between installations. Some of the factors that affect solar power system installation costs for specific homes include:
The amount of electricity your home uses
Homes that use more electricity will need more solar panels to cover their energy needs.
Although solar panels do get cheaper on a per-watt basis, the overall cost of the system will increase as more panels are added.
But, the higher a home’s energy usage, the more solar panels can save the homeowners on their energy bills.
The type of solar panels you buy
The price of solar panels can vary depending on the type of solar panels you choose.
There are two main types of solar panels for residential solar installations: monocrystalline and polycrystalline. Monocrystalline solar panels tend to be more efficient and more expensive than other solar panels. Polycrystalline panels have a lower efficiency rating and come at a lower price point.
The type of inverter you buy will also influence the cost of your solar system.
The quality of your solar installation
You may see some solar quotes with prices that seem too good to be true.
If you get quoted for a ridiculously cheap price, the installer might be using low-quality equipment or an unsustainable pricing model. You want to use a solar installer that is charging enough so that they can stay in business - as you’ll be relying on them for the next 25 years!
It’s important to make sure that your installer is giving you the best quality at the best price possible. This is why getting multiple solar quotes is so important.
Federal, state, and local solar incentives
The overall cost of solar can be influenced by the solar incentives available.
Across the U.S., homeowners can apply for the federal solar tax credit, also called the ITC. The solar tax credit makes installing solar more cost-effective by providing homeowners with a tax credit equal to 26% of the cost of their installed solar panel system.
Local solar tax incentives and rebates can end up saving homeowners thousands on a solar installation, especially when they’re used with the federal solar tax credit.
See what solar incentives are available in your area by using our solar panel calculator.
How is the cost of solar panels offset by solar tax credits in San Antonio?
The cost of installing residential solar panels in San Antonio varies with the brand of solar panels and inverters you choose, the installation company you choose to install them, the relative ease or difficulty of installing solar panels on your home, and of course the amount of solar panels you need. The amount of solar panels you need is, in turn, related to your energy usage.
Are solar panels worth it in San Antonio in 2022
The table below shows the data extracted from a real life quote delivered through the SolarReviews marketplace recently for a fairly typical home in San Antonio.
As you can see the payback period is relatively short and equates to a much better return on investment than he historical returns that have been available from investing in things like shares or property.
Table 2: Cost, savings and payback period for an average residential solar system in San Antonio
| System information | Value |
|---|---|
| System Size (for 100% usage offset) | 10.47 kW |
| Annual power generation | 13,042 kWh |
| Pay-back time (assuming Cash purchase) | 9.6 Years |
| Internal rate of return (IRR) on investment | 5.9% |
| Gross cost | $27,803 |
| Total Upfront Incentives and Rebates | -$7,228 |
| Net Cost of System after rebated and incentives | $20,571 |
| Total Cost of Utility Power Avoided over 25 years | $68,858 |
Please note that the investment return figures do not include the possible increase in property value
