Industry-Leading Warranties

Longhorn Solar offers customers some of the best warranties and guarantees in the solar industry:

  • Equipment Warranty — Through Longhorn Solar’s partnerships with leading solar panel and solar inverter manufacturers (more on that below), the company provides homeowners with a 25-year equipment warranty, meaning the company will replace or repair a defective or damaged system component at any time during the first 25 years of operation.
  • Workmanship Warranty — To supplement the equipment warranty, Longhorn Solar provides its own workmanship warranty of 25 years. The workmanship warranty protects the solar PV system against installation errors. In short, Longhorn Solar works to ensure its customers never have to pay for labor or maintenance on their solar panel systems.
  • Performance Guarantee — Longhorn Solar guarantees its solar energy systems will operate at peak performance for as long as they’re in use, and gives homeowners a clear expectation of how much energy they’ll produce over time.
  • No Pressure Guarantee — The solar installation industry is sometimes marred by companies with pushy salesmen, deceptive, even predatory upsell tactics, and lack of followthrough on promises made prior to signing the contract. Longhorn Solar’s account managers are trained to listen to customers’ energy goals, stay within their budget, and maximize their savings potential. They arm customers with all the tools they need to make an informed decision.

Top-Level Solar Panels and More

To assemble its elite solar energy systems, Longhorn Solar has partnered with some of the top solar equipment manufacturers in the world. The company uses solar panels from REC Solar, a leading solar panel producer with panels that achieve greater than 21 percent energy efficiency (considered a top five panel line). In addition to REC Solar panels, Longhorn Solar also installs Q Cells solar modules.

Longhorn Solar also sources its micro inverters from SolarEdge, an industry leader whose solar inverter products convert solar energy into usable electricity at a near-100 percent clip, and allow customers to monitor the performance of individual panels.

In addition to these top-level panels and inverters, Longhorn Solar also provides backup battery solutions through the LG Chem solar battery. The LG RESU10h provides homeowners with up to 9.8 kilowatts of renewable energy that can be used at night or in case of emergency or power outage. The solar installed also carries the Tesla Powerwall.

Top 500 Solar Contractor

Longhorn Solar has installed more than 14,000 kW of clean energy since its founding in 2009. The sheer quantity and quality of its work across more than 2,100 installation projects has earned Longhorn Solar a coveted spot on Solar Power World’s “Top 500 Solar Contractors” list every year from 2012 to 2020.

Community Solar Initiatives

As part of Longhorn Solar’s mission to put a solar panel system on every Texas roof, the company regularly participates in community solar projects through its Community First Initiative. To make solar power more accessible in underserved Texas communities, Longhorn Solar takes $500 of the purchase price as well as donates $100 to a school program or classroom for every system it installs in one of its Community First neighborhoods.

NABCEP Certification

Longhorn Solar has received a certification from the North American Board of Certified Energy Practitioners, an organization that provides advanced solar panel installation and solar technology training, and is considered the gold standard certification program in the solar industry. The presence of an NABCEP certification can indicate to customers that the company's technicians are true experts in their field.

The Bad

  • No Lease or PPA Options
  • Only Available in Texas
  • No Verified Longhorn Solar Reviews

No Lease or PPA Options

Longhorn Solar does not appear to provide cost-effective financing options like solar leases and power purchase agreements (PPAs); though the company does mention it provides a number of flexible loan financing options in addition to direct purchase of a solar panel system.

Only Available in Texas

Longhorn Solar is only available in the Lone Star State, a competitive solar market that features more than 600 individual solar companies and installers. Highlighting verified Longhorn Solar reviews on its own website as well as trusted review sites can help the company separate itself from competing solar providers in its area.

No Verified Longhorn Solar Reviews

Despite the solar provider's accomplishments and industry-leading warranties, no verified Longhorn Solar reviews exist on Best Company. Verified reviews play an important role in establishing a company's reputation online. Verified reviews also provide potential customers with unfiltered information on the solar installer's customer service, solar installation quality, and whether Longhorn Solar is the best solar company for them.
