Good Faith Energy review

Who they are

Founded in 2014, Good Faith Energy is a Dallas–Fort Worth-based solar, battery, and roofing company that has grown into one of the most highly regarded installers in Texas. Headquartered in Addison, it serves the entire metroplex — and its reputation is built on a premium, customer-first approach rather than the aggressive door-to-door sales tactics that give parts of the solar industry a bad name.

What genuinely sets Good Faith apart is the breadth of what it can do under one roof — literally. Most solar installers only install solar. Good Faith is Tesla Powerwall certified and operates an in-house roofing division. For a DFW homeowner, that combination solves the single most common and expensive problem in residential solar: an aging roof. If your roof needs replacing before panels go up, Good Faith can do both jobs together, so you never face the costly "remove and reinstall" trap of paying to take panels off and put them back on a few years later.

The Tesla Powerwall certification is more than a badge, too. In Texas, the Oncor rebate of up to $9,000 requires qualifying battery storage — so an installer who is genuinely fluent in battery design isn't a luxury, it's the difference between capturing that incentive and leaving it on the table. Good Faith designs solar-plus-storage systems as a core competency, not an afterthought.

The honest trade-off is price. Good Faith positions itself at the premium end of the DFW market, so it will rarely be the cheapest bid you receive. What you're paying for is durable equipment, meticulous installation, battery and roofing expertise, and a local company with the reputation and staying power to stand behind its work for decades. For homeowners who see solar as a 25-year investment rather than a bargain hunt, that premium is easy to justify.

Services offered

Equipment & warranty

As a premium installer, Good Faith focuses on durable, well-warrantied equipment rather than the cheapest components available. Here's what typically goes on the roof and how the coverage works.

A Good Faith system carries several layers of warranty coverage:

• Panel product warranty: typically 25 years against manufacturing defects, plus a performance warranty guaranteeing output as the panels age.
• Inverter warranty: generally 12–25 years depending on the inverter type chosen.
• Tesla Powerwall warranty: 10 years, covering the battery's operation and retained capacity.
• Workmanship warranty: Good Faith's own coverage on the installation itself — and because they also do the roofing, the roof penetrations are handled and backed by the same accountable team rather than split between two contractors pointing fingers.

Pricing & financing

Good Faith Energy is a premium, quote-based installer, which means it doesn't advertise a flat per-watt price. Instead, pricing is tailored to your roof, system size, equipment, and whether you add a battery or roofing. In the DFW market, that places it above value installers like Solartime (around $2.75/W) but with higher-end equipment, certified battery integration, and roofing capability part of the conversation.

On financing, Good Faith supports the standard ownership paths that let you keep the full value of the system and any incentives:

Because you own a Good Faith system, you keep its full value — and crucially, pairing it with a Powerwall positions you to capture the Oncor rebate of up to $9,000. When you factor that rebate into the math, the gap between a premium Good Faith install and a bare-bones value quote narrows considerably.

What to expect: the install process

Good Faith's process reflects its premium, roof-aware approach — the roof assessment is front and center rather than an afterthought.

1. Consultation & bill analysis. Good Faith reviews your energy usage and, importantly, inspects your roof's condition to determine whether it's solar-ready or should be replaced first.
2. Custom design & quote. You receive a system layout, production estimate, equipment list, battery recommendation, and — if needed — a roofing plan, all in one itemized proposal.
3. Contract, permits & interconnection. Good Faith pulls city permits, handles any HOA approval, and files the Oncor interconnection application.
4. Roofing (if needed) & installation. If your roof is being replaced, that's done first; then the same team installs racking, panels, inverter, and the Powerwall — typically over one to three days.
5. Inspection & permission to operate. The city inspects, Oncor grants Permission to Operate, and your system switches on and begins earning credits.

Most projects run about 6–10 weeks from signed contract to switched-on system — a little longer if a full roof replacement is part of the job, which is still faster and cheaper than doing solar and roofing as two separate projects.
