Home Solar Battery Backup

Protect what matters most

Why a solar battery backup?

Home solar battery backup could help you save on your energy costs*, make the most out of the energy your system produces and prepare you for power outages**.

A solar panel system produces clean, renewable energy for your home. Adding a solar battery backup gives you more control over your energy generation.

You can store the extra energy your system generates in the solar battery backup and use the stored energy when it’s most beneficial to you. This might mean switching to stored solar energy at night or keeping the lights on during a power outage**. By using the energy stored in your battery backup at night, you use less electricity from the grid—potentially lowering your electric bills.

In fact, one of the top reasons homeowners decide on a home battery backup system is peace of mind. Knowing that you have a level of protection from outages helps you rest easy even when the unexpected happens.

You can even control exactly when and how you use the stored energy with user-friendly apps that provide a detailed look at your system.

What are the benefits of solar battery backup storage?

Solar batteries help improve your home’s ability to stay powered during grid outages and offer more flexibility with how you can take advantage of solar energy. With solar battery backup storage, you get:

Flexible energy usage:

You can store energy produced during peak daylight hours and use it to help power your home at night.

Control over grid power usage:

You can choose when you use electricity from the power grid (via your utility company) and when you use stored solar energy. This option is especially beneficial if your utility provider has a time-of-use (TOU) rate structure, in which electric rates are higher on certain days and times than they are on others.

Reliability during power outages:

You can keep parts of your home powered during adverse weather events that cause blackouts.

Financial incentives:

You can take advantage of solar incentives like the 30% federal solar tax credit if you are eligible1. The solar tax credit extends to cover solar backup batteries. And depending on where you live, local incentives might be available.

Eco-friendly energy consumption:

Adding a solar battery backup to your solar PV system is an eco-friendly way to get the most out of your solar energy. The more you can rely on renewable solar energy and decrease your dependence on fossil fuels, the more you can help reduce your carbon footprint.

Adding solar battery backup storage to your home energy system is more than just an upgrade; it’s a commitment to a sustainable and efficient lifestyle. These benefits underscore the importance of solar battery backup storage as a valuable component of a modern, eco-friendly home.

Step 1 of 3

Do solar panels work during a power outage?

When power outages arise from natural disasters, overloads or routine maintenance on the electric grid, your panels automatically stop generating energy—primarily to ensure the safety of utility workers working on the lines. This is because your solar panel system is wired into your electric company’s grid. Unless you have an additional setup, such as a solar battery backup system, your solar panels alone will not produce energy during a power outage.

Which solar battery backup to buy?

When it comes to backing up your solar panel system, selecting the right battery is crucial. At ADT Solar, we recommend lithium-ion technology for its unparalleled safety and reliability. Lithium-ion batteries also:

  • Have a long lifespan, typically 10-15 years or even up to 20 years with proper usage and (minimal) maintenance
  • Hold up well even if you do not charge them the recommended way
  • Do not require regular maintenance.

Lithium-ion batteries have a long lifespan thanks to their higher depth of discharge (DoD), which means you can use more stored energy before you need to charge them.

Among the top choices of solar lithium-ion batteries, we proudly offer two exceptional models: the Enphase IQ and the Tesla Powerwall 2.

Enphase IQ

The IQ 10™ all-in-one AC-coupled storage system, comprised of three base Encharge 3™ storage units, provides a total usable energy capacity of 10.1kWh and twelve embedded grid-forming microinverters. Connect multiple Encharge 10 storage systems to maximize backup potential for whole home backup.
The Enphase solar monitoring app keeps you updated on how much energy is stored in your Enphase IQ Battery. Better yet, using the app gives you control over when you:

  • Power parts of your home with the stored energy
  • Recharge your battery with energy produced by your solar panels
  • Direct the energy produced by your solar panels into your battery backup

Tesla Powerwall 2

The Tesla Powerwall 2 is a high performing battery that stores energy, detects outages and automatically becomes your home’s energy source when the grid goes down. It provides energy storage for solar self-consumption, time-based control and backup. With each Powerwall 2 you install, you get:

  • 13.5 kWh of usable energy
  • 90% round trip efficiency
  • 50 volts of internal battery DC voltage
Source: (1)

Unlike gasoline generators, the Powerwall keeps your lights on and phones charged without upkeep, fuel or noise.

How do I get a solar battery backup installed?

A solar battery backup like the Tesla Powerwall 2 and Enphase IQ can only be installed by a certified installer like ADT Solar. This helps prevent damage to your home and ensures you get the most value for your investment. Let a professional handle the tough work for you!

Enphase battery install by ADT Solar

Using the information your Home Energy Consultant collected during your consultation we’ll design your solar panel system, including the addition of your solar battery backup system. Once you’ve reviewed and approved your energy system design, your Solar Project Coordinator will use those details to submit the design to your local building department to get the permits approved.

ADT Solar will work with local officials to get the permits for your system approved, including;

  • Building permit—Some local building departments require homeowners with solar to get a building permit.
  • Utility company—Your utility company has to approve your system for interconnection to the power grid.
  • Homeowners Association—You will need approval from your Homeowners Association (HOA) if you live in a neighborhood where an HOA has authority over the exterior of homes.

The big day has arrived! It’s installation day. Your coordinator will work with you to schedule it on a day that works well for you. If you are also getting a solar panel system installed, it might be scheduled for the same day or a different day than your battery backup installation. You can rest assured that your solar battery backup installation is in good hands, as ADT Solar is an Enphase Certified Platinum Installer and a Tesla Powerwall Certified Installer.

After the solar battery backup battery and panels are installed, our team will conduct a quality inspection to confirm that your system is safe and ready to go. Local authorities from the building department will do their own inspection to verify that the system meets their standard of approval. And your utility provider will make sure that your system is ready for interconnection to the grid.

Once all inspections have been completed and all permits have been approved, the exciting part comes: You get to turn on your solar panel system and battery backup system! This is called getting permission to operate (PTO). Your system is now connected to the grid, and you can begin using it.

What are the incentives or tax credits available for solar battery systems?

The federal solar investment tax credit (ITC) is a tax credit that can be claimed on federal income taxes for 30% of the cost of an eligible solar panel system1. ITC also offers up to a 30% tax credit on the cost of a solar battery backup system installed by 2034. Additional rebates and tax credits vary by your location and utility company.

ADT Solar does not offer tax advice. You will need to consult with a qualified tax attorney to determine whether your solar battery backup is eligible for the federal solar investment tax credit.

Take the next step and find the right battery for your home

Whether it’s reliable backup power or gaining more control over your energy costs, our solar battery backup systems offer a great solution. When you choose the best option based on factors like your energy usage and what you want to power, you can experience many benefits.
