Understanding the Powerwall 2 vs. Powerwall 3 (and What’s Available in the UK)

It’s important to note that Tesla has introduced newer versions of the Powerwall. As of my last update, the Powerwall 2 has been the dominant model available for residential use in the UK for quite some time. It offers a 13.5 kWh usable capacity and a continuous power output of 5 kW, with a peak of 7 kW for 10 seconds. This is more than sufficient for most homes’ backup and energy-shifting needs.

Powerwall 3 has been announced and features an integrated hybrid inverter, meaning it can handle both solar and battery functions in a single unit. This could simplify installation and potentially offer some cost efficiencies in the long run. However, widespread availability of the Powerwall 3 in the UK is still developing, and the Powerwall 2 remains the most commonly installed and quoted model.

When getting quotes, ensure you are clear about which version of the Powerwall is being offered and understand its specifications. For most UK homeowners looking for a robust and proven solution, the Powerwall 2 is an excellent and readily available option.

How to Get a Tesla Powerwall Quote in the UK

Getting accurate pricing involves engaging with certified installers. Tesla works with a network of approved installers who are trained to handle the Powerwall system. Here’s how to go about it:

1. Visit the Tesla Website: Start by visiting the official Tesla Energy UK website. You can often find information on how to request a quote or connect with certified installers in your area.
2. Find Certified Installers: Tesla maintains a list of its certified installation partners. These companies are experts in solar and battery storage and will be able to provide detailed, site-specific quotes.
3. Request Multiple Quotes: Don’t settle for the first quote you receive. Contact at least three different certified installers. This allows you to compare pricing, warranties, and the overall service they offer.
4. Prepare for Site Surveys: Installers will typically conduct a site survey (either virtually or in person) to assess your property, your existing electrical setup, your solar PV system (if applicable), and discuss your energy needs.
5. Ask Detailed Questions: During the quoting process, ask about:
   • The total cost, broken down by components and labour.
   • The warranty period for the Powerwall unit and the installation work.
   • The expected performance and lifespan of the battery.
