Tesla Makes a Great Battery. Installing It Is a Local Job.

Ordering a Powerwall straight from Tesla can cost less. Here's what homeowners report about the wait once they do — with the sources — so you can decide with your eyes open.

Back to Blog

Let's get one thing out of the way: the Tesla Powerwall 3 is the best home battery you can buy. We're a Tesla Certified Installer, and it's the battery we recommend for most homes in the Inland Empire.

So this isn't a page about the product. It's about who puts it on your wall, because that's where the experience splits. You can order a Powerwall directly from Tesla, or a local certified installer can put in the exact same battery. Same hardware, same Tesla warranty, same app. Very different wait.

Yes, Tesla direct can be cheaper

Tesla makes the Powerwall, so it can sell it at its own price, and ordering direct may get you a lower number than a local installer can offer. We won't pretend otherwise.

What that price buys you is a spot in a national queue. Tesla sells nationally from one website, and your design, scheduling, and service all run through that one central operation: the app, and a scheduling team that isn't down the street.

What Tesla says the timeline is

Tesla's own support pages lay it out: permitting takes 2 to 6 weeks depending on your city, the install itself takes 1 to 3 days, and permission to operate from your utility takes another 1 to 6 weeks after that. Add the site assessment and design up front, and a smooth Tesla direct project runs about 2 to 3 months from order to power-on.

That's the plan. Here's how it goes in practice.

What homeowners actually report

Plenty of Tesla direct installs go fine. A Brea homeowner said the whole thing took about three months from signed contract to a running system, and a Las Vegas customer described the same three months with a fast, professional crew.

Then there's the other column:

  • A Hacienda Heights homeowner had an install scheduled for October 28, 2025. Tesla canceled it the morning of, by email. The new date was January 7, and when the crew showed up, they had the wrong parts.
  • A Texas homeowner said it took a full year from down payment to installation.
  • A Glendale homeowner who already had Tesla solar spent more than two years trying to get Powerwalls added, couldn't get the project manager to respond, and gave up and went with another company.
  • A San Francisco homeowner waited four months after the site survey, only for Tesla to cancel the order because it decided the roof wasn't accessible.

The ratings tell the same story: Tesla Energy sits at 1.9 out of 5 on ConsumerAffairs across 590 reviews, and 2.79 out of 5 on SolarReviews across more than 1,200. Review sites do hear from unhappy customers more than happy ones. Read a few pages anyway, and the pattern repeats: installs canceled at the last minute, wrong parts, and long stretches where nobody answers.

Why it's happening

This isn't a knock on the people who show up in the Tesla trucks. The reviews of the crews themselves are often excellent. It's about how the operation is built.

Tesla has been winding down its own install crews for the last couple of years. In September 2024 it started recruiting outside certified installers as it scaled back in-house installations, and by 2026 Tesla's own support pages describe a hybrid model where certified installers handle the work in areas Tesla doesn't install directly. Electrek's read on it: installing is local, labor-heavy, low-margin work, and Tesla never managed to scale it profitably.

That's the whole story in one line. Installing a battery is local work: a permit with your city, a crew that knows your utility, a truck that can come back Tuesday. A company that sells globally is running that from a national queue. A local installer runs it from down the street.

After the install

The queue doesn't go away once the battery is on the wall. Southern California customers report a service visit scheduled 30 days out and then canceled the day of (Rancho Cucamonga), months of waiting for an appointment that gets canceled at the last minute (Palm Springs), and six months of emails to get an install problem fixed (Colton). That's the most common complaint on both review sites.

Same Powerwall. Local crew. About a month.

Here's what changes when a Tesla Certified Installer like Pell Solar puts in your Powerwall:

  • Same battery, same warranty. It's the same Powerwall 3, and Tesla's warranty applies either way. You give up nothing on the hardware.
  • About a month, not a season. Right now our battery installs are running about a month from signed contract to permission to operate. We pull the permit, do the install, and handle the utility paperwork ourselves.
  • A person, not a queue. We've been family-owned in Upland since 2003. When something needs attention, you call our office and talk to someone who knows your system, not an app ticket that gets you a date four months out.
  • One contractor for all of it. Solar, battery, EV charger, panel upgrade: one licensed local contractor (CSLB #949122), with local reviews you can check.
