EcoWatch Criteria for Selecting the Top Solar Company in Texas
EcoWatch has almost two decades of experience as a leader in environmental news. Our reviews and ranking methodology is not based on partnership agreements, which run the risk of bias for review sites that depend on such agreements. Read more about our EcoWatch criteria on our methodology page.
Warranty
How well is your solar roof covered? Two types of warranties back solar panels, both an equipment and performance guarantee:
- Equipment warranties often guarantee 10 to 12 years of efficiency.
- Performance warranties guarantee 90% of production for 10 years, followed by 80% at 25 years.
Year Founded
Solar is surging, but the demand for solar energy means you may encounter a fly by night solar company that isn’t experienced as it should be in solar services. Your warranty won’t hold up if the company goes out of business. Review the longevity of the company alongside its consumer reviews.
Services Offered
Solar panels are the primary product focus of solar companies as they design your solar energy system. However, you may be surprised to find that a solar company also offers electrical services, energy efficiency packages and roofing services. Such comprehensive services reveal the experience behind the brand.
Brands of Solar Equipment Offered
Are you searching for the most efficient solar panels or the most affordable solar panels? Reputable companies will first ask about your needs vs. upselling you their highest-grossing product.
If you prefer a certain brand, focus on the services and products sections of a solar company’s website. Not all companies offer a Tesla Powerwall, for example.
Industry Affiliations
Another indicator of a reputable solar company is its industry affiliations. Here are a few important affiliations to look for:
- Solar Energy Industries Association (SEIA)
- North American Board of Certified Energy Practitioners (NABCEP)
- B Corp certification
Size of Company
The size of the solar panel company you are working with is just as important as its reputation and the products it offers. A smaller solar company has more experience navigating local renewable energy policies and may be faster to respond to customer service inquiries. The person providing you with the solar quote may also be your installer, if you prefer. You may also find that local provider estimates differ per city, such as in Dallas vs. Houston.
However, their prices may be higher due to customizations needed. A larger solar company has access to bulk purchasing that brings costs down, without inverter or backup battery pricing being over the top. Unfortunately, larger companies may have difficulty addressing local issues quickly or interpreting area based needs.
Solar Pricing and Financing
A lower price point doesn’t ensure a high quality product, upgrades or service for home solar panel installation. Is the solar panel company offering a reasonable price for the quality of the service or equipment it’s offering?
The total cost of solar installation is also affected by the specific energy needs of your home. What is your goal for energy savings? What is your monthly electric bill? Where you live, roof configuration, the complexity of the solar installation, and the equipment needed are all factors you should take into consideration as you gather each free quote.
Besides pricing, pay attention to the financing options a company cites. Does the solar company offer solar loans, leases, or PPAs? Is it better to pay for everything upfront? Many reputable solar companies also display their solar loan partners on their websites. This type of transparency indicates that you will receive a fair solar installation estimate suited to your needs.

EcoWatch FAQ: Best Solar Companies in Texas
Elon Musk once indicated that it would only take a small corner of a state like Texas covered in solar panels to power the entire country, or 100 by 100 square miles. Texas is one of the biggest solar markets, which means your questions about going solar set the tone for the future of solar. If you have specific questions that aren’t answered here, reach out to our team of solar experts at solar@ecowatch.com.
We found that SunPower was the Best Overall company for solar power due to its experience and an excellent warranty. However, more of a local provider may be best for you. For example, Solar time USA is well known for customizing solar energy systems for its consumers and knowing the ins and outs of Texan weather and climate policy.
We definitely understand if you’re raising your eyebrows at another website giving “ratings” to companies for their products and services. That’s not what we do. An EcoWatch rating ranks a selection of companies on a .5 scale across the various categories we’ve covered above, such as services offered vs. what industry standards are; as well as customer satisfaction. You can read more about our methodology here.
Ultimately, an EcoWatch rating means that the solar companies we list are ones you can trust to deliver on what they say they will, and if not, keep us informed.
Yes. Many solar panels actually perform better in cooler climates, since they can become sluggish in extreme heat. The weather in Texas is subtropical, which means that the area can present a challenge during design. Issues like the extreme flooding in Texas mean that you want a solar installer that will recommend the right solar panels and solar equipment.
EcoWatch recommends getting a few quotes from solar companies to compare and contrast total costs, and you will also gain more insight once each company conducts an energy audit.
Compare the financing options as well: Is it better for you to pay in full, lease, or take out a loan? What solar incentives or solar rebates are available? Does it explain the federal tax credit? Does the company offer any of its own PPAs? Is net metering offered?
Overall, it’s a combination of solar panel efficiency and weather. Demand for solar is surging in Texas, and that means rates are also competitive. However, Texas is a deregulated energy market and a state that has experienced extreme weather over the last few years. A business prepared to address these factors will prove to be the best solar panel company.
