What it is, factually
The Tesla Powerwall 3, plainly, and whether it's worth it
The Powerwall 3 is a 13.5kWh battery with an integrated solar inverter, and it's expandable if you need more capacity later. Tesla publishes the specs and warranty terms directly. We'll always cite Tesla's own figures rather than our own claims. Whether it's worth it depends on the same thing any battery does: your usage pattern and tariff. As a Tesla Approved installer we'll fit one properly and safely, but we won't tell you it's automatically the right choice, because it isn't always.
What a Powerwall costs to install in Dorset, and how many you need
A single 13.5kWh Powerwall covers most Dorset homes, and higher-usage households sometimes need two. The figures below are our honest starting point, confirmed exactly at a free survey.

Is the Powerwall right for you? An honest look
We're a genuinely Tesla Approved installer, and we'll fit a Powerwall properly if that's what you want. But warranty is the true indicator of a battery, not the badge on it, so here's where we'd point you elsewhere, and why.
The Powerwall is a good fit if
- You already want the Tesla name and ecosystem
- You want a single, well-known integrated unit
- You're comfortable with Tesla's own published warranty terms
We'd steer you elsewhere when
You want the longest available domestic warranty. EcoFlow's standard 15-year term is longer than Tesla's.
See why we recommend EcoFlowYou want a battery with a gateway for full power-cut backup built into the inverter as standard.
EcoFlow Ocean 2 detailBudget is the deciding factor and you want the best value-for-warranty option.
See the Fox ESS optionYou need genuinely off-grid capability, with no mains connection at all.
See the Sunsynk option
We'll never say a negative word about Tesla. We're proud to be an approved installer. We'll also quote you an identical Tesla system to any other installer's quote, so you can compare like-for-like.

Adam Khodabaccus
We recently had solar panels and battery storage installed at our property in Poole by New Gen Renewables, and I couldn't be more impressed with the service we received. From the very start, the team were incredibly helpful, knowledgeable, and professional. They took the time to explain everything clearly and made the whole process feel smooth and stress-free. We're already seeing the benefits of going solar.
Neil Smith
Great service from New-Gen! Very personal and very reasonably priced. Had 24 panels installed with inverter and 2 batteries. All working perfectly.
How much does a Tesla Powerwall 3 cost to buy and install in Dorset?
Our general 5kW solar + 10kWh battery system guide starts from £8,825 including scaffold. A Powerwall-specific installed price depends on your property and is confirmed at a free survey.
Is a Tesla Powerwall actually worth it?
It can be, and we'll tell you honestly either way at survey. What matters is your usage pattern and tariff, not the brand, which is also why we'll show you the EcoFlow and Fox ESS alternatives before you commit.
How many Powerwalls do I need for my house?
Most Dorset homes need one 13.5kWh Powerwall, higher-usage households sometimes need two. We confirm the exact number at a free survey against your real annual consumption.
Can anyone install a Tesla Powerwall, or do I need a certified installer?
You need a Tesla Approved installer, New Gen is one. High-voltage battery installs aren't a job for an uncertified electrician.
Is the Powerwall the right battery for me, or is there a better option?
Sometimes, it depends what matters most to you. If the longest warranty and a built-in backup gateway matter more than the badge, we'd point you to EcoFlow, our recommended domestic battery. We'll never say a bad word about Tesla, we're simply honest about the alternatives.
Can I have a Powerwall without solar panels, or add one to solar I already have?
Yes to both. We retrofit batteries to existing solar (including systems we didn't install) and fit battery-only systems with no panels at all. See our battery storage hub for the full picture.
