Tesla Powerwall® Battery KEEP YOUR LIGHTS ON WHEN THE STORM ROLLS THROUGH

Independently Power Your Home Day & Night with Tesla Powerwall® Battery

Enjoy reduced energy bills and full control of your solar energy with Tesla Powerwall!

Your Tesla Powerwall will turn your SunPower solar panels into an all-day resource and store excess energy so it’s available on demand, even after the sun sets and during power outages. Powerwall enables your home’s electricity use to come from solar energy, enhancing the solar functionality and reducing your energy costs.

The combination of solar energy and Powerwall will independently power your home day and night. Solar panels may produce more energy than your home uses during the day and Powerwall will store that excess energy so it’s available on demand, even after the sun sets.

Answering Your Questions About the Tesla Powerwall

 

What does the Tesla Powerwall do?

A Tesla Powerwall stores excess solar energy during the day and uses it to power your home at night or during outages. It can also be used with or without solar panels, but solar panels are ideal for maximizing self-reliance.

How long can a Powerwall keep my home running during a power outage?

During a power outage, how long a Tesla Powerwall keeps your home running depends on two factors: Powerwall capacity and your home's energy use. A single Powerwall can typically power essential appliances (lights, fridge) for several hours.  However, to run your entire house for an extended time, you might need multiple Powerwalls.

The appliances it can power depend on their wattage.  Low-wattage appliances like refrigerators and lights will run for longer, while high-wattage ones like ovens and dryers will drain the battery much faster.  It's recommended to prioritize essential appliances during an outage to maximize runtime.

Does the Tesla Powerwall require maintenance?

Tesla Powerwalls are designed for minimal maintenance. Unlike lead-acid batteries, they don't require electrolyte checks or replacements. The system itself monitors battery health and performance. You'll mainly focus on keeping the surrounding area clear and well-ventilated for optimal operation. Tesla also offers a warranty on the Powerwall for added peace of mind.

 

What are the benefits of having a Tesla Powerwall? Will it significantly reduce my electricity bills?

A Tesla Powerwall offers several benefits that can impact your home's energy use and costs:

  • Increased Self-Reliance: Powerwall stores excess solar energy, letting you use it at night or during outages, reducing reliance on the grid and potentially lowering electricity bills.
  • Reduced Electricity Costs: By using stored solar energy instead of grid power, Powerwall can significantly decrease your dependence on expensive peak-hour electricity rates (depending on your utility plan).
  • Backup Power During Outages: No more scrambling during blackouts! Powerwall provides backup power, keeping essential appliances running or even your entire home operational depending on the system size.
  • Environmentally Friendly: Utilizing solar energy and reducing grid dependence contributes to a cleaner energy footprint.

However, the impact on your electricity bills depends on several factors:

  • Solar Panel Integration: Powerwalls work best with solar panels. The more solar energy you generate and store, the less you rely on the grid, potentially leading to significant bill reductions.
  • Your Utility Rates: If your area has high peak-hour electricity rates, Powerwall can help you avoid them by using stored solar energy during those times.
  • Energy Usage: Powerwall's impact depends on your household's energy consumption. High energy use may require a larger Powerwall system to see a substantial difference in your electricity bills.
