The energy storage system for a sustainable home
Whether you’re a homeowner with an existing solar panel system or plan to have one installed you will want to ensure you are making the most of the energy your panels are producing, discover how Tesla Powerwall 2 can help you get more from your Solar PV system.
Powerwall is a home battery that charges using electricity generated from solar panels, or when utility rates are low, and powers your home in the evening.
Automated, compact and simple to install, Powerwall enables you to maximise self-consumption of solar power generation.
By capturing and storing excess electricity generated by your solar panels during the day, that energy can then be used by your home during the evenings or on days with poorer weather, which can reduce your electricity bills significantly.
The Tesla Powerwall comes with the ability to ride through powercuts, giving your home added security. It’s like having insurance for your home energy system.
It’s also possible to fill the Powerwall with cheap night-time electricity, which is especially useful in winter when there is less solar energy to be captured by the battery. With a solar PV array and a Powerwall, you might never pay full price for your electricity again.
The Powerwall offers a large 13.4kWh energy storage capacity so is an ideal companion for larger households, or for those wanting to run their electric car. For smaller households there are other Solar battery options which may be more cost effective.
The Tesla Powerwall is a beautifully designed, sleek, minimalist product which looks great either inside or outside any home.
For those who love to see how their system is working it comes with a clear mobile phone app to show you when your battery is charging and discharging, and if you are using any electricity from the national grid.
Frequently Asked Questions
How Does the Powerwall Work?
The Tesla Powerwall is a rechargeable lithium-ion battery system. It uses the electricity generated by sunshine from a solar PV system which is over and above what your home needs during daylight hours, to charge the battery.
This stored electricity can then be used to power the building once the sun has gone down or during poor weather, or even in the event of a powercut.
How Long will the Tesla Powerwall Battery Last?
The amount of time that a Tesla Powerwall will be able to power your home will depend on a the electricity demand – such as lights, appliances, and potentially an electric car. For example the average household uses around 10 kWh (kilowatt hours) per 24-hour period. You will be using a lot less during a sunny day with your solar PV.
This means that your Tesla Powerwall could power your home for at least a day with its 13.4 kWh of battery storage, from a full charge.
How many kWh is the Powerwall?
Tesla Powerwall 2 has a 13.4 kWh capacity, with 13.2 kWh of that being usable for energy storage. It has a power output of up to 5 kW
