We were first to install the Tesla Powerwall in the UK. The Powerwall is a game-changer, saving you money on energy bills and ensuring zero downtime. The same Tesla technology that’s revolutionised the EV market is now available to power and provide energy back-up for your home.
Tesla Powerwall empowers homeowners and commercial property owners to store clean solar energy for use round-the-clock, and incorporates all the smart technology you’d expect from Tesla.
Now installed with Backup Gateway it provides protection from power cuts (an increasing risk due to the strain on the UK’s aging energy infrastructure). A home solar PV system without the addition of a Powerwall will shut down during a power cut for the safety of the grid. However, teamed with Powerwall battery storage system solar panels continue to produce energy during an outage.
This feature makes it an attractive option for homeowners and businesses needing to keep freezers frozen, lights on, machinery operating, and tills working during grid outages. Tesla Powerwall owners can also take advantage of the cheapest energy rates in the UK, saving up to 75% on utility bills by topping up energy during off-peak tariffs.
With no upfront cost and affordable monthly payments, the Hometree Solar Plan covers your equipment and installation, plus system monitoring and maintenance for complete peace of mind.

Each Tesla Powerwall has a 13.5kWh energy storage capacity which is 100% available for discharge depending on the reserve level you set, sufficient to power most homes during the evening using electricity generated by solar panels during the day. Multiple batteries may be installed together for homes with greater energy needs.
We are one of the leading Tesla Powerwall installers in the UK and certified as a Premium Installer in 2024. We were the very first renewable energy specialists in the country to install a Powerwall and have continued to lead the field in our technical expertise, volume of readily available Powerwall stock and successful install rate.
Our Powerwall installation sees us take care of everything from system design, DNO registration, installation, and commissioning. Powerwall comes with a 10-year unlimited cycle warranty with guaranteed energy retention level when used in Self-Powered or Backup mode. Although customers obtain peace of mind from the product manufacturer, choosing a reputable installer is just as important.
The Little Green Energy Company has been designing, suppling, and installing renewable energy systems to residential and commercial customers across Kent, Surrey, Sussex and the South-East, since 2010. Our aftercare continues long after we have left a property and our customers feel safe in the knowledge that we’ll still be there for them should they need our support.
So, if you are looking for an approved Tesla Powerwall installer near you, get in touch. We will provide you with our latest Powerwall pricing, availability and fitting lead times in the area.
Tesla Powerwall Battery Storage can be installed alongside any new or existing Solar PV installation or on its own to take advantage of Load Shifting. Load Shifting is simply buying energy during a cheaper off-peak time and using it during the peak time to reduce the cost of the energy. That is to say, you moved the cost of the load to a different time period rather than moving the load timing itself. This is also called time of use grid purchasing.
A typical installation with solar includes solar panels and an inverter for converting the DC energy generated by the panels into AC.
Tesla Powerwall battery storage system and Tesla Gateway with current sensors which controls the battery and tells it when to charge and discharge. In backup applications, a secondary circuit may be required that powers key appliances particularly for properties with three phase power. Single phase homes can be fully backed up with a maximum continuous power draw of 5kW per Powerwall installed. The components you require will depend on how you use your home battery and your grid energy supply.
Few businesses across the UK have reached this milestone. Our customers can trust that they’re getting the highest quality service and products from a Which? Trusted Trader certified installer.
How does the Tesla Powerwall work with a solar panel system?
During the day your Solar PV system supplies to any load being demanded in the property and the excess charges your Tesla battery. At night your home draws electricity from your battery, powering your home with clean, sustainable energy 24/7. Tesla Powerwall 2 can also charge from the grid during cheaper off peak times, it comprises of 13.5kWh of usable storage in a lithium-ion battery pack, which can power an average 2-bed home for a whole day.
How much does a Tesla Powerwall cost and how does it compare on value for money?
With up to 13.5kWh of storage and capable of delivering 5kW of power continuously and up to 7kW for 10 second periods, the Tesla Powerwall is extremely good value as the price per kWh of storage is by far the lowest on the market. Smart technology enables you to take advantage of time-of-use and export tariffs.
Many installers provide a cheap price of the Tesla Powerwall to lure you in, and then the price increases massively when you go into the detail or at the point of install. This unpleasant practice is called ‘bait-and-switch’.
We were Tesla’s 1st certified UK installer and we’ve built our reputation on 100% transparency. The cost of a Tesla Powerwall depends on the type of property you live in and the work involved to integrate it for optimum performance. You can call our team for a Powerwall cost and they will guide you through what you need, when it can be installed, and how much it will cost.
You can then take your time to make your decision on whether you wish to go ahead or not. We don’t use pressure tactics. We just provide a customised quote and price for you.
How does the Tesla Powerwall protect from power cuts?
With the ever-increasing load on the UK’s aging power grid, it is only a matter of time before we start to see regular power outages or planned power cuts in certain regions of the country.
Backup Gateway will detect a power outage and trigger your Tesla Powerwall 2 battery to take over. It will also ensure your Solar PV system continues to produce and utilise your green energy (without it, Solar PV stops working during a power cut).
How much could I save on my utility bills with Tesla Powerwall?
Take advantage of the cheapest energy rates in the UK, saving up to 75% on your utility bills by selling power back to the grid during peak rates with the appropriate energy tariff. Intelligent forecasting software learns when energy is most needed and helps maximise your financial benefits.
What does the Tesla Powerwall guarantee cover?
TLGEC is a fully-certified Tesla Powerwall installer. We take care of everything from system design, DNO registration, installation and commissioning. Tesla Powerwall comes with a 10-year unlimited cycle warranty with guaranteed energy retention level when used in Self-Powered or Backup mode. Call us for latest Powerwall battery availability, cost, and installation timescales.
Where can the Tesla Powerwall be installed?
The unit mounts seamlessly, indoors or outdoors, to a wall or the ground. In total 10 Tesla Powerwalls can be linked together to offer a massive 120 kWh of battery storage, ideal for larger homes or commercial application.
In practicality however, a single phase domestic property with 100A supply can have a maximum of 3-4 units installed and depending on the line to neutral impedance. A three bed domestic property will be well covered by 1-2 Powerwall’s. Larger domestic properties with 100A three phase supplies, can benefit with one Powerwall per phase (so three units) as a minimum and up to three Powerwall’s per phase (nine units) for heavy energy users or light commercial installations.
