Energy independence with battery storage
Tesla Powerwall is a smart home battery system that stores energy for when you need it most — day or night, during outages, or when electricity prices peak. It works seamlessly with your solar PV system to maximise self-consumption and minimise reliance on the grid.

Why Geowarmth for Solar?
Energy Independence
Tesla Powerwall allows you to store excess solar energy or low-cost off-peak electricity, giving you reliable power even when the grid goes down. It’s a key step toward true energy independence.

See how much you can save in three easy questions
Do I need a Tesla Battery?
If you already have solar panels – or plan to install them – adding a Tesla Powerwall gives you far greater control over your energy. It stores excess electricity to use at night or during blackouts, and even works with time-of-use tariffs to save you more money. For those without solar, Powerwall can still charge from the grid during low-cost periods and discharge during peak demand.

Energy Independent Community Centre
For a local Community Centre overlooking the Yorkshire fields, we took advantage of the outdoor space and designed and installed a free standing ground mounted solar array to serve the centre’s needs.
Frequently Asked Questions
How does the Tesla Powerwall work?
Tesla Powerwall stores electricity either from your solar panels or from the grid during off-peak hours. It automatically supplies power to your home when needed — including during power cuts — and helps reduce your reliance on the grid.
Can I add Powerwall to my existing solar system?
Yes. Tesla Powerwall is compatible with both new and existing solar PV systems. It integrates with your inverter and backup gateway to store and deliver electricity efficiently.
Is Tesla Powerwall worth it without solar?
Even without solar, Powerwall can charge using cheaper off-peak grid electricity and discharge during peak-rate times — saving you money through energy arbitrage.
What size home is a Tesla Powerwall suitable for?
Each Powerwall offers 13.5kWh of usable storage, enough to power a typical 2–3 bedroom home for a day. Multiple units can be installed together for homes with higher energy demands.
Where can Tesla Powerwall be installed?
Powerwall is designed to be mounted indoors or outdoors, and works in all weather conditions. Our team will help you find the best location based on your home’s layout and energy usage.
