Arizona Brightbox hero

Arizonans enjoy roughly 299 days of sunshine every year.1 That's a whole lotta sun power. And Arizona is third in the "Top 10 Solar States" for solar capacity installations.2

It's clear that Arizona relies a good deal on the sun as a renewable energy source. But there are times when Arizonans need additional power support, like during blackouts and when the sun goes down.

We now offer a solar + home storage batteries service solution with our partners at LG Chem - the world leader in lithium-ion batteries. LG Chem's technology is among the most proven and reliable in the world - and the perfect battery solution for rooftop solar systems. BrightboxTM solar battery service is only available for new Sunrun customers.

3 Brightbox™ Benefits for Arizonans

  1. Peace of Mind When the Power Goes Out
    Who wants hassle and frustration during a power outage? With our Brightbox™ solution, you can power your home through an outage. And how is the battery powered? Reliable back-up loads for your battery are powered from excess energy generated by your solar panels from all that sun. (Yeah, we think this technology is cool, too.)
  2. Performance Guarantee & Savings
    We guarantee your energy production for savings you can count on. Brightbox™ automatically adjusts so that you pay the lowest utility payment possible, even when your utility rates rise during peak hours.

    Most of the year your battery will be fully charged before time-of-use (TOU) peak hours. Utility rates are usually highest right after work and during dinner hours. And energy consumed after TOU peak hours will be at a battery charge of 20%. Which is still plenty enough energy to power most appliances.3

  3. Long-Term Solar Savings & Financing Flexibility
    Some homeowners can use power during the day to avoid higher energy prices at night. Many of us cannot due to our busy schedules. But whether you use power day or night, Brightbox™ helps guarantee the lowest utility bill payment possible.
    Sunrun also offers flexible options to own, finance or lease our Brightbox™ solar plus battery storage solution. (Please note that you can lease today with $0 down, and start saving right away.)

Frequently Asked Questions

Brightbox is a home solar battery service that offers clean, reliable and affordable power. Brightbox can be used for backup when the grid is down, or give you better control over your home energy use and cost.

Brightbox stores the electricity your rooftop solar produces during the day for when you need it most, such as in the evening, at night, or when the electric grid fails.

Yes. Brightbox is part of Sunrun’s holistic solar as a service offering. When you choose to go solar with Sunrun, you can add a Brightbox home battery if it is offered in your market.

Brightbox installation is a relatively simple process. The battery itself is about the size of a water heater and easily mounted on a wall—usually inside your garage or outside of your home. The clearance required for a Brightbox battery and its accompanying components is 6.5’ H x 10’ W.

Our expert electricians will take care of installing and configuring your battery for you. Batteries last anywhere between 10 and 15 years, and manufacturers typically offer a 10-year warranty.

Still, Brightbox is more than home batteries; it’s a holistic service that includes professional maintenance and monitoring during the life of your agreement. Customers who own their battery get Sunrun service for 10 years, while customers with a BrightSave Monthly or Prepaid contract get free battery maintenance replacement for the lifetime of their contract - generally 20 or 25 years.

You can monitor your Brightbox battery’s performance on your mySunrun app. Sunrun also manages the battery remotely using proprietary software so we keep tabs on your system 24/7 to make sure it’s running as it should, and automatically updates your battery’s settings to save you as much money as possible.

Our BrightSave Monthly and Prepaid solar plans come with 24/7 proactive monitoring and maintenance, on us. So if we notice that your Brightbox or solar panels aren’t working at their full capacity, we’ll send an expert over to fix it without you having to lift a finger.

At this time, Brightbox is only available to new Sunrun customers.  We can’t install Brightbox if you already have an existing solar installation or if it isn’t offered in your area.

However, if you’re still interested in Brightbox please let us know—you’ll be the first to know when we’ve come up with a solution. We’re hard at work on optimizing our technology to provide an even more seamless customer experience.

The amount of available backup power depends on what you choose to back up, what time of day and season the power outage happens, and how much energy your household uses. If the battery is fully charged, it can provide 8-12 hours of backup. If your battery has been discharging throughout the day, it automatically holds a 20% reserve for a backup emergency, or about 3-4 hours for a blackout when the sun is down. When the sun comes back up, your Brightbox will start to charge again!

The electrical circuits in your home that power your lights and appliances are all connected to breakers, safely regulating the amount of power that feeds each circuit. Multiple appliances can be powered by one breaker. For instance, one breaker could power your refrigerator plus nearby outlets or lighting in your kitchen. While you can’t necessarily target individual appliances, with Sunrun Brightbox you can choose which breakers you’d like to back up. What you can back up depends on the current wiring of your home.

You can use a portable generator—however, Sunrun doesn’t offer backup generators. If you’re interested in installing a portable generator, you can contact a local electrician or renewable energy installation company. These experts can recommend a system that will be appropriate for your home.

Please note that Brightbox cannot be installed on homes that already have a standby generator.

Having a home solar battery service in Arizona will help save money by offsetting high Time-of-Use (TOU) rates while offering peace of mind when the power goes out. Plus, our long-term savings and financing flexibility let you go solar on your terms.

Your system is also covered by our Sunrun Guarantee, so we handle maintenance and repairs at no additional charge.

One of Arizona’s best solar incentives is the state’s Renewable Energy Production Tax Credit, covering 25% or up to $1000 of your system’s cost. Another major incentive is the Federal Solar Tax Credit, covering a generous 30% of the total system cost.

Other Arizona incentives include sales and property tax exemptions and Arizona Public Service’s Solar Export Plan (or net feed-in tariff). For more information on Arizona solar incentives, click here.

For customers with our BrightSave Monthly and Prepaid products, Sunrun applies for these rebates and tax credits, and automatically includes the savings from these rebates in the price we offer our customers.

For most households, one solar battery is sufficient to power your most important appliances. In the event of a blackout, your Brightbox battery provides approximately 8-12 hours of backup power.

When the sun rises, your solar panels charge your battery so you can continue to back up your home until utility power is restored.

In the event of a power outage, your Brightbox automatically discharges power to your critical home appliances.

In the event of a power outage, appliances like your refrigerator, electronics chargers for cell phones, laptops, and your TV can be backed up by Brightbox for 8-12 hours. When the sun rises again, your solar panels will recharge your Brightbox. The most important rooms and appliances in your home will be powered by your home battery until the grid is up and running again. To learn more about how home solar batteries work, click here.

Brightbox works in tandem with the grid, and is not designed as an off-grid solution.
