Save some sunshine for later
When your panels produce more than the house needs, Powerwall can store the surplus for the evening. More of the electricity you generate stays useful at home.

On your terms.
A home battery should have a clear job to do. We’ll help you decide how solar storage, tariff charging and backup fit into your life.
Make use of different rates
With a suitable time-of-use tariff, you can charge when electricity costs less and use stored energy later. We’ll explain the practical benefits for your usage.
Plan the backup you need
If backup matters to you, we’ll design it into the installation and explain which appliances or circuits it can support, and for how long.

The aim is simple: make the electricity available when your household needs it.
The Tesla app lets you see your system and manage its settings. We’ll help you understand the monitoring and controls at handover, so you can get comfortable with everyday use.
Explore the Powerwall detailsGenerate now. Keep some for later.
Solar powers the home first. Surplus generation can then charge Powerwall for another time.
Use the energy you put aside.
When solar generation falls, stored energy can help run your home. The grid supplies any additional electricity needed.
Support what matters in a power cut.
A correctly specified backup installation can supply the agreed circuits during an outage, within the battery’s available charge and power limits.
Illustrative operation. Actual behaviour depends on system design, settings, available charge and household demand.

questions, answered.
You don’t need to know all the technical terms. Tell us what you’d like your system to do and we’ll talk you through the options.
0191 340 7001Can I add Powerwall 3 to my existing solar panels?
It may be possible, and it’s something we can assess for you. We’ll check the existing panels, inverter, electrical supply and system layout before recommending how to add storage. If you already have Powerwall 2, tell us: Powerwall 3 cannot simply be added to a Powerwall 2 system.
Will Tesla Powerwall keep my home running in a power cut?
Powerwall can provide backup when it is installed with the appropriate equipment and configured for that purpose. We’ll agree which circuits and appliances need support and explain the system’s limits. Backup duration depends on the charge available, what is running and whether the solar panels can recharge the battery. Backup should be specified in your proposal, rather than assumed.
Can I charge Powerwall from an off-peak electricity tariff?
Yes, with a suitable tariff and system settings. Tesla’s time-based controls can use differences between lower and higher electricity rates. We’ll help you understand how this relates to your household use. Tariffs change, and the benefit depends on the rates, losses, settings and amount of electricity you move between those periods.
How much does a Tesla Powerwall installation cost?
The installed price depends on the battery configuration, backup requirements, location of the equipment, electrical work and whether new solar panels are included. We’ll survey the property and provide a written quotation showing what is included. That gives you a useful figure for your home rather than a headline price for equipment alone.
What warranty comes with Powerwall 3?
Tesla provides a 10-year limited warranty, subject to its terms. Reliable internet connectivity is required for the full warranty. We’ll explain the manufacturer cover, the installation cover and who to contact for help before you go ahead, and provide the relevant documents at handover.
Is there 0% VAT on solar panels and battery storage?
Qualifying installations of solar panels and electrical battery storage in residential accommodation currently benefit from 0% VAT until 31 March 2027. Eligible standalone battery installations and battery retrofits are included. Equipment bought on its own is not covered by this installation relief. We’ll confirm the VAT treatment in your quotation.
Do you install Tesla Powerwall across the North East?
Yes. Our Washington-based team works across Newcastle, Gateshead, Sunderland, North and South Tyneside, Northumberland, County Durham and Teesside. We’re a family-run company established in 2006, with local installation, servicing and aftercare.
