Why This Homeowner Chose Solar + Battery Storage
We recently helped a homeowner who wanted a Tesla Powerwall 3 installation in Derbyshire, with backup gateway, alongside a new solar PV system.
Their aim was straightforward; reduce energy bills, store more of the solar power they generated, and have a reliable backup option in case of power cuts, especially over winter. The homeowner was also motivated by the potential to lower installation costs, particularly with current VAT exemptions. The backup option was especially important due to the increased risk of power outages during winter.
After walking them through the options, they decided that the Tesla ecosystem offered the all-in-one solution they were looking for.
Assessing The Home’s Energy Needs
Before installing a Tesla Powerwall 3 together with solar PV system, we worked closely with the homeowners to thoroughly assess their home’s energy needs. Together, we reviewed their energy usage patterns, especially during peak hours and periods when electricity demand and costs were highest. This collaborative approach allowed us to recommend the right size and configuration for their battery storage system, ensuring they received the maximum benefit from their investment.
During this process, we also identified opportunities to improve energy efficiency, such as upgrading to more efficient appliances and adjusting daily routines.
Our guidance helped the homeowners not only maximise the advantages of their Tesla Powerwall 3 but also take meaningful steps toward greater energy independence. With the tailored system in place, they were able to reduce their electricity bills, store more energy for use when needed, and enjoy reliable backup power during outages.
Our team’s expertise and personalised recommendations ensured the battery storage solution was perfectly suited to their family’s specific needs, helping them achieve both savings and peace of mind from day one.
Enhancing Energy Efficiency Before Installation
Maximising the benefits of their Tesla Powerwall 3 began with our advice on making the home as energy efficient as possible. We suggested simple yet effective upgrades, such as switching to LED lighting, installing smart thermostats, and selecting energy-efficient appliances, all of which contributed to lowering their energy bills and reducing reliance on the grid. We also recommended improvements to insulation and sealing to minimise heat loss and energy waste, further enhancing the performance of their solar and battery system.
Additionally, we reviewed the planned, bespoke solar panel system to ensure it was optimised for seamless integration with the Tesla Powerwall 3. By focusing on energy efficiency before installation, we helped increase overall energy production and storage capacity, enabling the family to store more clean energy and use it when it mattered most. These measures not only made their system more sustainable but also maximised the return on their solar investment, supported by our ongoing guidance and support.
System Overview: Tesla Powerwall 3 + Solar PV
This was the first Powerwall 3 installation carried out by our team and our first as an approved Tesla Partner Installer. Compared to previous models, the Powerwall 3 features a higher inverter capacity and improved solar storage capability, delivering more power and efficiency for demanding households.
Here’s what we installed:
- Tesla Powerwall 3 – a compact battery with built-in inverter, using advanced batteries with robust thermal management for long-term performance. The Powerwall 3 can be expanded with additional units for greater capacity and is designed to supply reliable energy to the home, even during outages. It delivers enhanced power output, supporting more appliances and higher loads, including heat pumps and electric vehicle chargers.
- Tesla Backup Gateway – provides automatic power switch-over during outages
- Roof-mounted solar PV system – tailored to the household’s average energy use and available roof space
The Powerwall 3 integrates seamlessly with solar PV and the Tesla app for a smooth user experience. It is also suitable for businesses seeking reliable backup and energy savings.
The installation was completed by our in-house team, who are trained and certified to Tesla’s latest standards. As an electrical business specializing in solar PV, we bring expertise to every project.
Technical Specifications and Requirements
The Tesla Powerwall 3 is a fully integrated solar and battery storage system designed for maximum efficiency and reliability. With its built-in integrated solar inverter, the Powerwall 3 streamlines installation and boosts overall system performance. It offers a robust storage capacity of 13.5kWh and delivers a continuous power output of 11.04kW, making it suitable for most UK homes and their energy needs.
One of the key features of the Powerwall 3 is its use of Maximum Power Point Trackers (MPPTs), which allow for flexible solar panel layouts and help maximize energy production from your solar system. The Powerwall 3 is engineered to provide reliable backup power during outages, ensuring your home stays powered and secure even when the grid goes down.
To ensure the system meets all technical requirements and delivers optimal performance, it’s important to work with a certified installer, such as our awesome team here at Coactivation Solar. We assess your property, recommend the best configuration, and handle the installation process to guarantee a smooth transition to greater energy security and efficiency.
Solar PV and Battery: Energy Production and Monitoring
Pairing the Tesla Powerwall 3 with solar panels creates a complete solution for powering your home with clean, renewable energy. Thanks to its integrated solar inverter, the Powerwall 3 efficiently converts and stores the energy your solar panels produce, allowing you to maximize your solar investment and reduce your reliance on the grid.
With the Tesla app, you can monitor your energy production and usage in real time. This powerful tool gives you full control over your system, letting you track how much energy you’re generating, storing, and using throughout the day. By analysing this data, you can make informed decisions to further enhance your energy efficiency, lower your carbon footprint, and ensure you’re getting the most out of your Powerwall 3 and solar panels.
Whether you want to optimize your energy use, save money, or simply enjoy the peace of mind that comes with reliable backup power, the combination of solar PV and Tesla Powerwall 3 puts you in control of your home’s energy future.
Benefits of Tesla Powerwall 3 for UK Homes
One of the standout features of the Powerwall 3 is that the inverter is built into the unit. That means fewer components and a cleaner install, which can help with efficiency and aesthetics.
With the Backup Gateway in place, the system monitors the grid in real time. If there’s a power cut, it automatically switches to stored battery power. For homes that want backup without the complexity or noise of a generator, this setup works really well.
Powerwall also works seamlessly with solar, storing excess power generated during the day so it can be used in the evening or overnight. This allows homeowners to maximise their use of solar energy and cost savings by making the most of the electricity they generate.
How This System Supports Energy Independence
Before the install, this Derbyshire home was completely reliant on the grid. If there was an outage, everything stopped. Now, they’re generating their own electricity during the day, using more of it on-site, and have backup in place if the power goes down.
The homeowners now benefit from:
- Solar energy during the day
- Stored energy for later use
- Automatic switch to battery power in an outage
- More control over energy use and costs
They haven’t gone off grid, but they’ve taken a meaningful step toward greater energy independence and peace of mind.
