Tesla first introduced their Powerwall battery system in 2015 to help store energy for solar self-consumption. In 2022, the Tesla Powerwall 2 is one of their most popular products. You can use the Powerwall as a backup and an alternative for powering your home during a power outage.

While the Powerwall isn’t really a necessity, investing in one can take your dedication to going green to another level. If you’ve simply chosen a Tesla Powerwall for the monthly savings, we encourage you to read on to find out the other benefits of owning the world’s most famous battery system!

What is a Tesla Powerwall?

A Tesla Powerwall is an integrated battery system; storing your solar energy for blackout protection. This feature, while not unique, is one of the more attractive reasons for choosing the Tesla Powerall, as the battery will continue to provide power to your home, and be recharged by your solar panels, even when the grid is down. Many other solar batteries will not recharge when the grid is down – some batteries do not even come with blackout protection.

You can use the Powerwall to supplement your daily energy usage. This battery system is connected to software for optimizing production and provides energy usage monitoring.

There are many reasons to combine your solar PV system with a Tesla Powerwall. Some of these reasons include increased efficiency, backup power, and reduced energy costs. Let us take a look at the advantages you and your family can enjoy when using a Tesla Powerwall with solar panels: 


You can finally have energy independence from energy companies and their demanding, costly bills with a solar PV system. With a PV system, you can have all the free solar energy consistently hitting your panels. Exciting, right? 

However, there is so much more than this narrative. You may enjoy the benefits of switching to solar power, but regardless of your drive to going green, the bills still keep showing up. Yes, the bills may be cheaper, but let’s say you still aim to save a little more. Suppose this is the case, then combining your solar PV system with a battery system like the Tesla Powerwall can do the job better for you.  

Maximize Your Solar PV System

When combining your solar PV system with a Powerwall, you can store the excess energy generated during the day and use it in the evening. Your Powerwall can help you maximize your solar system while also saving more on electric bills, eliminating waste, as well as minimizing your own carbon footprint. 

EV Charging and V2G Capability

You can finally use your Powerwall to generate electricity for your Electric Vehicle (EV). Your EV can utilise the energy stored in your Powerall to charge its own battery. While the energy stored in your battery may not provide your EV a full charge, it will provide ample energy to save you money from high petrol prices. During a blackout, your EV will be able to use the energy stored in your Powerall to stay on the road.

Blackout Protection

Who likes a power interruption? Other than lighting up a candle or using your phone’s flashlight to check food in the fridge, one nuisance of blackouts is interrupting our use of technology. After all, many of us now work from home and we use technology in most facets of our lives.

It is common for us to worry during a power interruption, especially when we’re reaching a deadline or working on a presentation. While these may be major issues for many of us, there is still a lot of danger that comes with a power interruption. 

The truth is, even if you have solar panels installed on your roof, as soon as the grid is affected, your PV system will cease to generate power. Solar generators are not allowed to export energy to the grid. This is to protect linesmen who may be working on the grid to restore power. But in the event of a power interruption, a Tesla Powerwall can prove priceless.

Your Powerwall can give your home blackout protection. During an outage, your Powerwall immediately disconnects from the grid, then creates its own mini-grid. When the network fails, your battery system can guarantee you energy independence. You may not even realise that you have lost power!

Your Tesla Powerwall can still function without connecting to a solar PV system. You can simply get energy from the grid and save it for a grid outage. Unlike the USA, you can purchase a Tesla Powerall 2 as a standalone battery – you do not need to purchase the solar panels or solar roof in order to install a Powerall and connect it to a new or existing solar PV system.

Why Consider A Tesla Powerwall?

One essential thing to keep in mind when deciding if the Tesla Powerwall is right for you is the cost. The system itself is not cheap, with a price tag of around $8000 before installation. However, when you factor in the long-term savings on your energy bill, the stability it provides during blackouts, and the independence it grants from the grid and electricity providers, it can provide great value for money and peace of mind.

Many utility companies propose incentives for customers who install solar batteries like the Powerwall. These incentives could further offset the initial cost of the system. The Tesla Powerwall is indeed one of the most efficient home batteries on the market, with an average efficiency of 97%. This indicates that for every 100 watts of energy you generate, you will use 97 watts to power your home. This is a significant improvement over traditional lead-acid batteries, which have an efficiency of around 50%.

Finally, you need to consider installation when deciding if the Tesla Powerwall is right for you. The great news is that the Powerwall is relatively easy to install. Solar Battery Installers in Melbourne often offer a variety of financing options to make it so much simpler for you. In most cases, you can have the system up and running in just a few days.
