Frequently Asked Questions
How long does it take to install a Tesla Powerwall?
Usually, one full day for a standard installation. If you’re adding solar or upgrading your main panel, it may take a bit longer — but we handle everything start-to-finish to make the process smooth and efficient.
Do I need solar panels to install a Powerwall?
No, you can install it without solar. But pairing it with solar gives you the biggest savings and ensures the battery recharges from clean energy instead of the grid. Most California homeowners choose the combined system because it pays off faster.
Will the Powerwall power my whole home during an outage?
Yes, one Powerwall 3 can back up most homes entirely thanks to its higher power output. During the design phase, we’ll review your home’s electrical needs and make sure the system is set up exactly the way you want it.
Do I need to upgrade my electrical panel?
Sometimes, depending on the age and capacity of your panel. Don’t worry – we evaluate this during your free assessment and take care of all needed upgrades as part of the installation process.
How long does a Powerwall last in an outage?
Most homes get a full day or more of backup, depending on usage. Essential loads like refrigerators, lights, Wi-Fi, and outlets can run even longer. We’ll help you understand exactly what to expect for your home.
Can the Powerwall be installed outdoors?
Yes – Powerwall 3 is designed to be installed indoors or outdoors, and it’s fully weather-rated for California conditions. Our team will recommend the safest and cleanest location on your property.
What maintenance does a Powerwall require?
None. It’s a sealed, self-managing system. Tesla monitors the battery remotely and updates it automatically. Once installed, it simply works.
Will I still get power if the grid goes down?
Absolutely. Your Powerwall switches over instantly during an outage – so fast you won’t even notice. Most homeowners don’t realize the grid is down until they see neighbors without power.
How much space do I need for installation?
Powerwall 3 has a compact footprint and requires only a small wall area with clearance around it. We’ll measure everything during your site assessment and find the cleanest installation point.
What is the warranty on the Tesla Powerwall?
Powerwall comes with a 10-year manufacturer warranty and is designed for long-term daily cycling. As a certified local installer, we also stand behind our workmanship and support after installation.
