4 Brightbox Home Battery Benefits for Hawaiian Homeowners

1. The Sun Never Sets with Brightbox

Solar panels are just the first step towards energy independence. For those unpredictably overcast days, rainy afternoons, and when the sun goes down, your Brightbox battery’s stored up solar energy kicks in to keep your home running on the sun.

So why rely on expensive, imported electricity?2  With a home battery storage system, it’s as local as you can get.

2. Financing Flexibility

Like everything we do, Brightbox is designed for simplicity. Which means you can power your home your way, day and night. We have flexible options to own, finance or lease a home battery. In fact, you can start leasing your Brightbox system for as little as $0 down.

3. Superior Service

We do the work so you don’t have to. Our flexible solar leasing options come with 24/7 proactive monitoring and maintenance, on us. If we notice that your home battery or solar panels aren’t working at their full capacity, we’ll send an expert over to fix it. We’re always standing by to make sure your home battery is in top condition, so you can keep powering on.

4. Control Over Your Energy

Brightbox puts your energy needs first. Our smart storage technology and a seamless online user dashboard gives you control over your energy usage. The more you know, the closer we get to putting the power back into your hands.

Frequently Asked Questions

Hawaii has some great solar incentives in place, offering even more reasons to go solar in the Aloha State. One of its best incentives is the Renewable Energy Technologies Income Tax Credit, covering 35% or up to $5,000 of the cost of your solar system. Top that off with the 30% federal solar tax credit and property tax exemptions and you could see over 50% in savings on your home solar system.

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 approximately  8 to 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.

In Hawaii, our home solar and storage service utilizes your solar power, offers affordable rates during peak usage times, and offers financing flexibility starting at $0 down.

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

Just like solar panels, the size of your Brightbox solar home batteries is determined by your unique energy needs and habits. Our solar advisors are here to help select the right home batteries solution for you.

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.

In the event of a blackout, you’ll have an outlet to connect up to four small appliances or an extension cord, drawing from available energy in your battery.

When the sun rises, your solar panels recharge your Brightbox battery until the grid is back up again. Learn more about how home solar home batteries work.

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.

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.

To maximize savings with Brightbox, aim to use more power during the day while the sun is shining brightest. That could mean running appliances like the dryer or A/C while you’re out at work. The more power you use when the sun’s up, the more effectively you can save with your Brightbox battery.

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.

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.

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.

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.

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.

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.

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.
