This means that we can install a Tesla Powerwall battery for your home, your solar PV or wind turbine system.
Powerwall is a lithium-ion battery system that turns solar panels into an all-day resource while offering backup power in the event of a grid outage.
A Tesla Powerwall battery maximizes the usefulness of your solar panels and offers a variety of electricity storage and backup supply solutions.
The Powerwall can be installed in any home with or without microgeneration and to any existing microgeneration system regardless of who originally installed it.
Powerwall must be installed by a Tesla Energy Certified Installer
SW Dart Ltd is an established electrical contractor with over 20 years of experience in the electrical, solar and sustainable energy industry throughout Devon and across the South West. After a lengthy selection process we are proud to have become a Tesla Energy Certified Installer.
We take great pride in providing innovative, effective and efficient energy solutions and only install the best products so the Tesla Energy Powerwall was the first choice when looking into supplying solar battery storage to our customers in Devon
If you’re keen to take advantage of this revolution in battery storage get in touch and we’ll be delighted to help.
During the day solar panels often produce more electricity than your home needs. Powerwall enables the storage of energy from solar panels during the day, or from the grid when energy rates are low; discharges energy for backup or use at night; and automatically optimizes home energy. Powerall thereby maximizes solar consumption and reduces energy spending.
Powerwall can be charged from solar or grid power and can provide backup power. If greater amounts of energy are needed, multiple Powerwalls can be installed together to work as a larger system.
The system uses as much self-generated power from the Battery (max 3.3kW Download Powerwall Datasheet) or Solar PV as it can. If the home consumption exceeds this any additional electricity requirement is imported from the grid.
During the day solar panels often produce more electricity than your home needs. This excess solar energy is automatically sent back to the grid and is no longer available for you to use. Powerwall enables you to store the excess energy produced during the day and use it – even when the sun’s not shining – meaning you get to consume more of the solar energy you’re generating.
Automated, compact and simple to install, Powerwall enables you to maximise self-consumption of solar power generation.
The Powerwall helps to increase the amount of self-generated electricity used directly by your home. The battery is charged up when your solar PV system or wind turbine is generating more electricity than is being used in the home. The battery stores this electricity, preventing it from being exported to the grid and discharges it when the local load exceeds electricity production, reducing the electricity bill.
The Powerwall is a home battery that charges up to 6.4kWh using electricity generated from solar panels powering your home in the evening.
The Powerwall also charges the battery when utility rates are low (e.g. Economy 7 or British Gas’s free Saturday) and powers your home in the morning.
The Tesla Powerwall can be added to any home with or without microgeneration and to any microgeneration system regardless of who originally installed it.
Powerwall stores electricity generated by solar panels during the day and makes it available to your home in the evening.
This bridges the gap between peak solar and peak demand, allowing you to use your solar energy when you need them.
Combine solar panels and one or more Powerwall home batteries to power your home independently from the utility grid.
A net zero energy rating means that your home produces as much energy as it consumes, but is still connected to the utility grid for periods of high demand.
Powerwall can power your entire home or select appliances with an uninterrupted supply of electricity during an electricity outage.
Powerwall will allow your home to use solar generated and stored electricity during a utility outage.
A typical home system includes Powerwall, solar panels, an inverter, a meter and an electrical panel. Which components are required depends on how you use your home battery.
Panels convert sunlight into electricity that charges Powerwall and powers your home during the day.
The home battery is charged with electricity generated by solar panels.
The inverter converts direct current electricity from solar panels and Powerwall into the alternating current used by your home’s lights, appliances and devices. All Powerwall installations require a compatible inverter.
To maximise solar consumption, a meter is also installed to measure battery charge, solar production and home energy use.
Electricity from the inverter is sent to your home’s electrical panel that distributes your power supply throughout your home.
The cost of Tesla Powerwall installation for the UK market varies depending on site layout.
For a site where the DC (i.e. the inverter) is local to the Powerwall – the installed Tesla Powerwall price is – £4,680 inclusive
For a site where the inverter is not local to the Powerwall (i.e. in the attic space or on another building) the installed Tesla Powerwall price is – £5,035 inclusive.
The Tesla Powerwall costs indicated include all installation materials, VAT @ 5% and we serve the entire South West region.
Based on these costs we believe that a Tesla Powerwall would pay for itself in approximately year 8.
