Awful
Panels were installed in May. It's the end of August and they have failed second inspection. Still no resolution. No one answers the phone and communication is non-existent.

We started looking at solar two years ago. We interviewed a lot of companies and salespeople. Every one of them we talked to were more interested in selling us something instead of helping us understand the pros and cons. Then we called Freedom Solar and along came Bradley Dette. He was awesome. He helped us with every question we had, made sure we understood how it worked and if it would be beneficial to us. We finally decided it wasn’t us. Two years later and several rate increases later we decided to look into solar again. We called Freedom solar again and talked to Brad again. He was more than happy to sit down with us again and help us decide if solar was for us. After talking to Brad we told him it was such a big decision that we wanted to interview more companies. Brad told us please do, I want you guys to be 100% happy with your decision. A few interviews later we decided Brad and Freedom Solar were our best choice. We are happy we did. The installation was great. It looks great. For us it is everything Brad said it would be. Freedom Solar and their people are amazing. Everyone cares about your happiness and approval. They treat your home like it is theirs. The panels and batteries we purchased are just like Brad said. We have been live for two months and the savings are already adding up. Our first bill is was $11.00. If you are thinking about solar consider talking to Bradley Dette and Freedom Solar.

I wish there was a ZERO star option
Terrible company to work with. Word to the wise - don’t do business with Freedom. Sunpower (their actual solar department, Freedom is just marketing) just went bankrupt & has ruined their free monitoring app. It’s now $10/month just to see historical data. Trust me, $120 a year really hurts the savings the system generates. No accountability, no follow-up, internal communication is a circus. They threw in a $1000 VIP rebate to get my system contract done, but then just never paid it. If I thought the civil suit would be worth my time, I’d file it. Doubt the $1000 would be worth a week of my time or however long they could stretch it out

Absolute Disaster
It's been 3 months, still not generating; they use the cheapest and slowest equipment to maximize their profit, but sacrifice customer. Customer care take 15 minutes to be connected, and every time, they put you on hold, and then the call gets disconnected while on hold after1-2 minutes. And they don't call back; so you have to call, wait another 15 minutes to be connected, and then the same thing happens. What a disaster of business they are running. AVOID!!

Best solar companies for home battery installations in San Antonio
Batteries have become increasingly popular because they take an intermittent energy source like solar and turn it into a reliable and consistent supply of electricity. We recommend getting a solar battery quote if you want a backup power source or if your utility company doesn’t have a net metering program that buys excess solar energy at the full price of power, as you could save a little extra on your electric bill.
Here are some San Antonio companies that install panels and solar battery storage systems:

How to find the best solar panel company near you
Picking a solar company is the most important decision you make when going solar. You need to trust them to drill holes in your roof, help you navigate financing and incentives and provide you with 25+ years of customer service.
Check out this video where our founder, who also founded a successful solar installation company, explains what to look for when choosing the best solar company near you.
Top things to consider when choosing a solar company in San Antonio:
Years in business
One of the first things to look at when finding a company is how long they have been in business. We suggest looking for companies that have been around for at least five years, as the longer it has been in business, the more likely it is you’ll have a positive installation experience.
Companies with five or more years of experience will probably have established after-sales service and warranty support. It signals that they aren’t a company in it to make a quick buck; they’re in it for the long haul.
Of course, there are exceptions to this rule, which is why you should also keep a few other factors in mind.
Licenses, insurance, and certifications
Solar companies that are licensed, insured and hold certifications take their business seriously. Look for companies that have NABCEP Certified professionals or certified electricians on staff and are properly insured, so their workers, and you, are protected.
Financing options
Not everyone has thousands of dollars to spend on a solar panel installation. So, you’ll want to find a company with solar financing options that work for you. Ask for quotes for various types of financing plans to see which one will work best for your budget. Solar loans are often your next best choice if you can’t pay in cash. But, if you don’t pay federal income taxes or can’t qualify for a loan, finding a company that offers solar leases or power purchase agreements might be the right move.
Services and products offered
Don’t choose a company that can’t complete the job that you want to be done. If you need an energy storage system, get quotes from companies that install batteries! Maybe you want a particular brand of panels or an electric vehicle charger installation. Ask the company if they provide those services or carry those brands so you don’t have to settle for less.
Customer review scores
Customer ratings give valuable insight into how a solar company actually operates and treats its customers. Read SolarReviews, Google and Yelp reviews to understand the company’s installation process, sales practices and overall customer service. But remember that some companies incentivize customers to leave positive reviews, so make sure you read reviews with some scrutiny.
Warranty
Any reputable solar installation company will offer a workmanship or labor warranty that covers any damages that may occur during the installation process. We recommend using an installer with at least a ten-year labor warranty.
Some installation companies, like SunPower, include a system performance guarantee. This promises you’ll get a certain amount of electricity from your solar panels and is an excellent added protection.
San Antonio incentives and rebates
Solar incentives and rebates can cut the cost of installing solar in San Antonio by thousands of dollars. The most significant incentive is the 30% federal solar tax credit, available to any taxpayer in the country when they purchase solar panels or battery storage.
Some cities, counties, states and utility companies offer additional solar incentives, saving homeowners even more money. Here are the solar incentives available in San Antonio:
| Incentive | Eligibility | Type |
|---|---|---|
| Residential Clean Energy Tax Credit | Federal | Personal Tax Credit |
| Renewable Energy Property Tax Incentive | State | Property Tax Incentive |

What to look for in solar quotes in San Antonio
Once you’ve found a few companies you like, you can start getting solar quotes. You can get a better deal when you get quotes from multiple solar installers; we suggest getting at least three quotes. Here are a few of my favorite tips and tricks for comparing quotes and what questions you should ask installers.
System size and energy production
All solar quotes should include the size of the system and how much energy it is projected to produce. Most of the quotes you get will probably be in the same ballpark. But, if one is drastically larger or smaller than the others — ask about it! Maybe one installer included shading from a tree, while another based its estimates on having that tree removed.
If you choose reliable installers, you can trust that these estimates will be as accurate as possible. But you can always double-check using the SolarReviews solar calculator and enter the information received in your quotes.
Pricing
You should know as much as possible about how much the solar panels cost. Make sure you know both the total cost of the system and the price per watt of solar installed. The cost per watt makes it easier to compare prices between quotes and gives you a better idea of how fairly the system is priced. The average price of solar is about $2.22 to $3.32 per watt in San Antonio, so anything in that range is a fair price.
Financing
Financing is one of the most important things to look for in your solar quote. There are a few different things to keep an eye out for, depending on what type of solar financing you’re using.
If you’re looking to use a solar loan, you should ask the company for both a cash quote and the financed quote. Solar loans include something called dealer fees, which can sometimes add 20% or more to the total cost of your system in exchange for a lower interest rate. It’s worth comparing what dealer fees and interest rates you’re quoted from different companies to get the best deal possible.
If you want a solar lease or power purchase agreement (PPA), you’ll want to look for an escalator clause in the contract. The escalator clause outlines how much your payments will go up every year. Ideally, this should be lower than the rate at which electric prices increase in your area, typically about 3% annually. If the escalator rate is higher than this, you could end up paying more than if you hadn’t gone solar at all!
Payback period
Some quotes may include when you’ll break even, meaning when your panels have saved as much as you spent on them.
If it’s not explicitly listed on the quote, you can compare any savings estimates they provide to the system’s total price and get a rough estimate of when your panels will pay themselves off. The shorter the payback period, the better.
Equipment
Good quality solar installers will carry good quality equipment. So if you pick an installer you trust, you can expect reliable products. But, it can’t hurt to research and ask the installer questions about what would be going on your roof.
Most solar panels installed today are about 400 watts in size and have efficiency ratings above 19%. Higher wattage and efficiency panels can produce slightly more electricity but may add a price premium. You’ll want to make sure the solar panels have the industry standard 25-year product and performance warranties.
