By Brad Smith, Home Services Expert · ✓ Data verified August 2026 · 8 min read

The businesses on this page range from 159 to over 28,000 reviews, and it's worth knowing which kind of company you're calling before you get a quote.

Short answer: Solstice Solar is the strongest true solar installer on this page, at 4.9 stars across 415 reviews, with SolRa Tech holding a perfect 5.0 across 159 reviews.

5 Best Solar Panel Providers in Houston (2026)

Our top picks, reviewed

#1 Overall🕑 Open 6 days/wk↩ Responds to reviews

Gexa Energy

4.728,034 Google reviews

Gexa Energy is a retail electricity provider in Texas's deregulated market, offering residential and commercial electricity plans rather than physical solar panel installation. It's the most-reviewed business on this page, with reviewers overwhelmingly discussing plan pricing, billing and customer service calls rather than any panel installation work. Customers with existing solar systems can sign up for plans through Gexa, but the company itself does not install panels.

What people praise

Most reviews of any business on this page, at 28,034
Customer service reps repeatedly praised for walking customers through plan options
Competitive pricing noted across many reviews
Long-standing provider, with some customers describing decades-long relationships

Worth knowing

No review on file describes solar panel installation; this is an electricity retailer, not an installer
Some reviewers report frustration with billing communication and customer service escalations

Our take: Included here for its Google category, but Gexa sells electricity plans, not solar installations. If you already have panels and want a retail electricity plan built around solar buyback, it's worth a call; if you need panels installed, look at the installers below instead.

Green Mountain Energy

3.93,350 Google reviews

Green Mountain Energy is a retail electricity provider marketing 100% renewable energy plans across several states including Texas, alongside a solar buyback program for customers who already have panels installed.

What people praise

Positions itself specifically around renewable and solar-friendly electricity plans
Some long-term customers report clear, understandable billing
Refer-a-friend credit program offered to customers

Worth knowing

Lowest rating on this page, driven by a notable share of 1-star reviews about billing disputes
No review on file describes solar panel installation; this is an electricity retailer, not an installer
Multiple reviewers report difficulty switching plans or getting solar buyback credits honored as expected

Our take: Like Gexa, this is an electricity retailer rather than an installer. If solar buyback rates specifically matter to you, ask detailed questions about the buyback terms before signing, since that's the source of several complaints in its reviews.

It has the widest range of feedback of the true installers on this page.

What people praise

Broad service scope, bundling solar, battery, generator and HVAC work
Long track record with over 28,000 systems installed
Project managers praised for clear, proactive communication during installs
Realistic system sizing rather than oversized upsells, according to some reviewers

It holds a perfect rating across nearly every review on file.

What people praise

Perfect 5.0 rating across 159 reviews
Handles solar detach and reset, useful if you need roof work done around existing panels
Fast response times, including same-day AC repairs
Transparent about equipment condition and options before recommending work

Worth knowing

Smaller review base than the more established solar-focused names on this page
Fewer reviews specifically describing full new solar installations versus its roofing and HVAC work

Our take: A good fit if you need solar work coordinated with a roof replacement or HVAC job, since it handles all three under one company. For a standalone, large-scale new solar installation, Solstice Solar has the deeper specific track record.

How we score

Every number on this page is computed from public Google data on the date shown, not from opinion or payment. Rating is the business’s live Google star average. Review volume is how many customers have rated them, ranked against other Houston solar-related businesses. Confidence weighs the rating by that volume, so a 4.9 from hundreds of reviews carries more weight than the same score on a handful. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

How much do solar panels cost in Houston? (2026)

Solar installation costs depend heavily on system size, whether battery backup is included, and available tax credits. A standalone panel install costs differently than a bundled solar-plus-battery-plus-HVAC package.

Do you physically install solar panels, or do you sell an electricity plan?

What is included in the written contract, including taxes and fees?
What is the typical timeline from signing to permission to operate (PTO)?

Frequently asked questions

How did you choose these solar panel providers?

We started from businesses related to solar panels in Houston with a public Google presence, then ranked by rating, review volume, consistency and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

What’s the difference between a solar installer and an electricity retailer with a solar plan?

An installer like Solstice Solar or Freedom Power physically puts panels on your roof. An electricity retailer like Gexa Energy or Green Mountain Energy sells you a power plan, sometimes with solar buyback rates for panels you already own, but does not install anything.

How much do solar panels cost in Houston?

Costs vary too widely by system size and included equipment to quote a general range responsibly. Get a free written estimate from more than one installer before signing.

The bottom line

Solstice Solar is the safe default for a genuine solar panel installation, while SolRa Tech is a strong pick if you need solar work bundled with roofing or HVAC. If you’re looking for an electricity plan rather than an install, Gexa and Green Mountain are retailers, not installers, so match the business to what you actually need before you call.
