Thinking about battery storage for your solar system? Now might be the perfect time.
Tesla has just made a major move with its latest battery storage system – the Powerwall 3 – by reducing the cost by up to £1,000 per unit. Whether you’re already solar-powered or looking to futureproof your home, this price drop makes Tesla’s most advanced home battery more accessible than ever.
So, what’s changed?
There are two major reasons for the price reduction:
- ✅ The unit price has dropped by £200
- ✅ The Powerwall 3 no longer requires a Gateway unit (saving around £800)
The Gateway is the kit that enables the Powerwall to keep your home running during a power cut. If you don’t need that functionality, you no longer need to pay for it. That’s a total potential saving of £1,000 per system – a major win for Somerset homeowners considering solar and battery storage.
What is the Tesla Powerwall 3?
The Tesla Powerwall 3 is a fully integrated solar and battery system designed to maximise your energy independence. It builds on the success of the Powerwall 2 with more power output, easier expansion for growing energy needs, and a built-in solar inverter, meaning solar panels can be connected directly to the unit for improved efficiency.
Whether it’s part of a new Somerset solar installation or added to an existing system, Powerwall 3 gives homeowners greater control over how and when they use energy.

Key benefits of Powerwall 3
- ☀️ Store your solar energy to use anytime – day or night
- ⚡ Use stored energy when grid electricity is expensive
- 🔋 Powerful enough to support most homes with just one unit
- 💡 Optional home backup in power cuts (if installed with a Gateway)
- 📉 Lower electricity bills by using your own stored energy
- 🧠 Smart energy management via the Tesla app – track usage, customise settings and optimise savings
- 🚀 Integrated solar inverter means a more streamlined, efficient system
- 🔧 Simplified installation with fewer parts and less electrical work
- 🧰 Easy to expand and integrate with existing systems
Whether you’re aiming to cut your energy bills, reduce reliance on the grid or gain peace of mind with backup power, the Powerwall 3 offers an intelligent and future-ready solution for Somerset homeowners.
Powerwall 3 Without the Gateway – Is It Right for You?
If you’re mainly interested in saving money and using more of your own solar energy, Powerwall 3 without the Gateway is a fantastic option. If having backup power in the event of a power cut is essential, the Gateway is still available; it’s just no longer a must-have for every home.
Either way, solar and battery systems in Somerset just became more affordable and flexible.
