Tesla Powerwall Certified Installer Sussex & Surrey
Tesla Powerwall 3 Installation Across Sussex and Surrey
Electrotec Power Solutions is a Tesla Powerwall Certified Installer based at Manor Royal in Crawley. We design and install the Tesla Powerwall 3 for homes across Sussex, Surrey and Kent, whether you already have solar panels or you are starting from scratch.
Why the Tesla Powerwall 3?
The Tesla Powerwall 3 stores 13.5 kWh of usable energy and has a solar inverter built in, so a new solar system can run without a separate inverter. It provides whole home backup in a power cut, and Storm Watch charges the battery automatically when severe weather is forecast. Paired with an off peak tariff such as Octopus Intelligent Go, your Powerwall can charge cheaply overnight and run your home through expensive peak hours.
Why use a certified Tesla Powerwall installer?
Tesla only allows accredited companies to supply and fit the Powerwall. As a certified installer we handle everything: free survey, system design, DNO application, installation, commissioning and registration of your 10 year Tesla warranty. We are also MCS and NICEIC accredited with over 2,000 installations across the region since 2011, and you can verify our status on the official Tesla certified installer list.
Tesla Powerwall with solar panels
Most of our Powerwall customers pair it with a new or existing solar array. We can design a complete solar panel system around the Powerwall 3, or retrofit it to your current setup. Not sure Tesla is the right fit? Compare it with our FoxESS and Sigenergy battery storage options and we will give you honest numbers for each.
Ask us about current Tesla Powerwall 3 rebates and offers when you book your free survey. Terms and availability change, so we’ll confirm exactly what applies to your installation.
Solar + Solar & Battery Installation
Solar Panels
Solar Panels for Crawley Homes
On a bright Sussex day, a well-sized solar system will produce more electricity
than your household uses — and any surplus can be exported to the grid via the
Smart Export Guarantee (SEG). On overcast days the system still generates, just
at a reduced rate. Over a full year, Crawley homeowners consistently see
meaningful reductions in their electricity bills.
Most properties in the Crawley area are well-suited to solar — from the town
centre terraces to the larger detached homes in Pound Hill, Maidenbower, and
Copthorne. Where a south-facing roof isn’t available, east/west split roofs and
ground-mounted systems are also options we can design for you.
Solar and Batteries
Solar & Battery Storage in Crawley
Adding battery storage takes your savings to the next level. Rather than
exporting surplus solar at a low SEG rate and buying it back at a premium
in the evening, a battery stores that energy for use when you need it most.
As electric vehicles become the norm, running your home and car from your
own stored solar energy will be the most cost-effective combination available.
We install FoxESS, SolarEdge, and Tesla Powerwall battery systems — all with
full UK-based technical support and long-term aftercare.
