About the Tesla Powerwall 2

Tesla Powerwall 2 batteries are cutting-edge solar battery storage technology that can save you money and reduce your reliance on energy from the grid.

These innovative solutions are a must when you install solar panels on your home, as they allow you to store unused energy generated by your PV system and use it when the sky is cloudy or during the night.

Even if you don’t have solar panels, you can still make the most of Tesla Powerwall batteries. By storing energy at night when it is cheaper and using it during the day, you can cut your energy bills significantly.

With AR Power, you can get a Tesla Powerwall 2 installed and ready for use quickly and easily. We are approved by the manufacturer and have extensive experience installing the Tesla Powerwall 2.

Our team covers the whole of the North East, including Durham, Gateshead, Newcastle, South Shields, Sunderland, and Washington. So, wherever you’re based, you can get the benefits of Tesla Powerwall batteries for your home.

Key Benefits Of Tesla Powerwall 2 Battery Storage

While there are many battery storage solutions available, the Tesla Powerwall 2 offers many benefits, including:
  • Creates A Self-Sufficient Energy System: Capture excess solar energy generated during the day and store it so it can be used in the evening, reducing your electricity bill significantly and limiting your reliance on energy from the grid.
  • Long Warranty: The Tesla Powerwall 2 has a 10-year warranty for unlimited cycles and 80% of the original energy capacity.
  • Affordable: The Tesla Powerwall 2 has one of the lowest costs per stored kWh on the market, and its large storage capacity allows it to provide great value.
  • Continuous Power: We install our Tesla Powerwall 2 batteries with access to the Tesla Backup Gateway, meaning you get constant power output even when the mains power goes down.
  • Always Connected: The Tesla App gives you full visibility of your household’s energy usage and consumption, solar production and self-consumption, as well as the battery state of charge and usage.
  • Flexible Installation: The Tesla Powerwall 2 is compatible with any solar PV system and can be wall or floor-mounted. Up to 3 Powerwalls can be installed per phase.
  • Quick Fitting: These innovative Tesla products are designed for easy installation by a certified installer, so AR Power can have your new Powerwall up and running in no time.
  • Weatherproof: Tesla Powerwall 2 batteries are fully waterproof and can be sited indoors or outside. The battery has an integrated temperature control system that heats or cools the battery and regulates its temperature. This means the battery can be stored outside, increasing the choice of installation location.
  • Touch Safe: The Tesla Powerwall 2 is touch-safe and comes with no exposed wires, so it’s safe for the whole family.
  • Long Life: The Tesla Powerwall 2 has liquid cooling controls, maximising battery life and safety, so it lasts for many years.

Tesla Powerwall 2 Cost Overview

The cost of a Tesla Powerwall depends on a variety of factors and will change over time. You’ll have to pay the cost of the unit itself and the cost of installation by a qualified engineer. The location of your electricity meter and where you want the Tesla Powerwall sited can also affect the installation costs. You can have up to 3 Tesla Powerwalls on the same Gateway, and the more batteries you get, the higher the cost.

Tesla Powerwalls can save money in the long run, as they help you store clean energy from your solar system to give you additional power when you need it.

To help you spread the cost, you may be able to apply for a Government grant designed to help homeowners reduce their carbon footprint, so you may not have to pay the full price for your Powerwall units.

Additionally, starting on the 1st of February 2024, buyers in the UK market can benefit from 0% VAT. Tesla has also increased production of the Powerwall recently as the product has become more popular, meaning the price is currently at an all-time low.

AR Power is committed to providing the most cost-effective Tesla Powerwall solutions to UK homeowners.

Tesla Powerwall 2 FAQs

Using a Tesla Powerwall in conjunction with a solar installation can reduce your reliance on fossil fuels and limit your use of energy from the grid. It can also allow you to power an electric vehicle, which will reduce your use of gas or petrol-powered transport. With the right solar panel system and Tesla Powerwall units, it is possible to meet your home’s electricity demand without relying on traditional energy sources during the spring and summer months.

Tesla Powerwalls can be used without solar panels. Most energy companies will give you a tariff where you pay a lower rate for energy at night, allowing you to charge your Tesla Powerwall with cheaper energy to use during the day when prices are higher.

Small businesses can make the most of their solar panels by installing Tesla Powerwalls. For larger businesses, we can create custom battery storage solutions to help you harness the unused power output from your large solar array.

The Tesla Powerwall 2 is the current battery offered in the UK, but the Tesla Powerwall 3 is due to be released in 2024.

This depends on the types of appliances you use, your home’s energy source, how many solar panels you have if you’re using solar generation and the size of your household. Generally, a Tesla Powerwall can keep your property self-sufficient throughout Spring and Autumn if used in conjunction with a suitable-sized solar PV array. For larger households that use more electricity, multiple Powerwalls can be installed to meet your energy needs.

Tesla batteries are specifically designed for power outages and will start powering your home should your mains power fail, providing you have enough charge in your battery. They can power the average home with several appliances running for hours, meaning that power outages won’t affect your life. With a Tesla Powerwall, you’ll always have backup power, provided there is enough stored energy in the unit.



Tesla Powerwalls are an ideal way to reduce the cost of your energy bills, whether you have an existing solar PV system or not. Stored energy generated from your solar panels can be used at night when there’s no sunlight to charge your solar panels, meaning you can use renewable energy for longer. You can also store electricity from the grid overnight when the price per kWh is lower, then use it during the day when the price per kWh is higher to cut costs. Your Tesla Powerwall can also reduce costs associated with power cuts by providing power continuously to appliances like freezers or heating systems.

It is possible to install multiple Tesla Powerwall batteries in your home. How many you can have will depend on what the Distribution Network Operator (DNO) allows and the amount of space you have. You can have up to 3 Powerwalls per phase, and if you have a larger home with 2 or 3 phases, you will also need a Tesla Powerwall Gateway and battery for each phase. Multiple Tesla Powerwall batteries can be stored on top of each other or be wall-mounted in a row, depending on your space and home layout. We can discuss your options further and provide bespoke guidance, so contact us for more information.

The Tesla Powerwall comes with a 10-year warranty, and its lifespan will depend on how much you use your battery, but most customers report that it can last 20 years or more.

The Powerwall Gateway is the control system for your Powerwall battery. It works with your energy supplier, be it from your solar panels or the National Grid, to control the energy going to your battery. You need 1 Gateway per phase, and most residential properties have 1 phase. If you have more than 1 phase, you will need a Gateway and Tesla Pwoerwall for each phase to balance the system.

Couldn’t recommend ARP enough. After installing our solar panels, they have kindly sourced and installed our solar battery. Despite being an old house and a tricky installation , they have made the whole process effortless. Thank you again!

We chose AR Power to install our Powerwall 2 battery and were not disappointed. From the moment of placing the order they took care of everything, right through to completion of the project. They were always happy to explain and update us on progress or explain any technical queries we had. Their installation engineers were competent, polite and tidy. We have ended up with a very neat and tidy job giving us exactly what we set out to achieve. We wouldn’t hesitate to use them again (but have now sadly run out of space!!!) and have no hesitation in recommending them to others.

I’ve been a returning customer to ARPower. I’ve used them for all my solar, battery and so on. I’ve recently just had a Tesla battery fit, and I couldn’t be happier. Strongly recommend ARPower.
