Installed prices
Seven packages, priced on the page
Named kit from LONGi, Duracell and Tesla at published installed prices. Each one has its datasheet and a calculator that starts from what you spend a month.

Two Hinen B15£9,800
Duracell Dura16£4,450
Two Duracell Dura16£8,900

Prices are installed. Both Duracell packages are priced for an installation alongside solar panels. Powerwall prices are from, subject to survey. Solar is £1,000 per kWp using the 530 W LONGi Hi-MO X10.
Which system suits you
Six batteries, compared honestly
Price, price per usable kWh, storage, warranty and backup, side by side. The cheapest box is not always the right one, and the biggest rarely is.
Lowest cost per kWh stored
Fill and empty a battery once a day for its whole warranty and the two Hinen packages cost 8.2p and 8.3p per kWh stored, the lowest of the six. Duracell works out at 8.5p and Tesla 11.0p to 12.9p. Hinen's 12-year warranty does a lot of that work.
A battery with no panels
With no new panels, the Hinen packages are the lowest installed price per usable kWh we offer: £358 for two and £365 for one, against £402 to £470 for the Powerwall 3. The Hinen B15 (£5,000) and the Tesla Powerwall 3 (from £6,350) are sold with or without solar. The Duracell packages are priced for an installation alongside solar panels.
Adding panels at the same time
All six packages fit alongside new LONGi panels. With panels going in, a Dura16 is £4,450, or £309 per usable kWh on a 10-year warranty. Size it to your evening use; your design call works that out from your bills.

Per kWh stored is the installed package price divided by everything the battery can store if it fills and empties once a day for its whole manufacturer warranty; per usable kWh is the price divided by the datasheet usable capacity alone. Both are arithmetic on the prices above, not manufacturer figures.
What it could be worth to a typical home
Pays back in 7.6 years
Pays back in 9.5 years
Pays back in 11.2 years
Estimated year-one benefit on the model every calculator on this site runs: 12 LONGi panels (6.36 kWp), a home using 2,700 kWh a year, 925 kWh per kWp (the average PVGIS yield across our county pages), a 12p export rate and off-peak charging at 8.5p. A bigger battery earns its keep in a home that uses more, or runs an EV or a heat pump. Run it for your own spend.
How solar and a battery work together
Make it at midday, use it at teatime
Panels generate most around the middle of the day. Most homes use most in the evening. The battery is what moves your own energy across that gap.
It stores your solar. Instead of exporting at a few pence and buying back at the 26.32p capped rate, the battery runs the home after dark.
It buys off-peak. On a smart tariff it tops up overnight at the cheap rate and covers the expensive evening hours.
It can open better export rates. Some of the strongest export rates are reserved for homes with solar and a battery; our export rates page names them and the conditions.

The things everyone asks
What does the free design call involve?
A 30-minute video call with Niall or Vince, our residential energy consultants, or a phone call if you prefer. Your roof on screen, your usage talked through, and the kit and the price that fit. Nobody visits your home, and nothing is booked until you say so.
What do the packages cost?
Solar is £1,000 per kWp installed, so ten 530 W LONGi panels (5.30 kWp) come to £5,300. A Duracell Dura16 is £4,450 and two Dura16 units £8,900 when installed with solar. A Tesla Powerwall 3 is from £6,350 and a Powerwall 3 with an Expansion unit from £10,850, subject to survey. The design call, the survey and your written quote are free.
Who carries out the installation?
We do. Our MCS-certified, fully insured installation teams install and commission every system to the design agreed on your call, backed by our workmanship warranty and the manufacturer's product warranty. Your written quote sets out the terms before you commit to anything.
Is there VAT on solar panels and batteries?
Not at the moment. Installing solar panels and batteries on a home in Great Britain is zero-rated for VAT until 31 March 2027, and reverts to 5% after that under current legislation. Our VAT deadline guide sets out how long a job takes from first call to switch-on.
Do I have to be with a particular energy supplier?
No. We explain how tariffs from suppliers such as OVO, Octopus Energy and E.ON Next work with solar, batteries, EVs and heat pumps, and you choose. Some of the strongest export and smart rates are reserved for the supplier's own customers, and we always tell you when that is the case.
What is MCS certification?
MCS is the Microgeneration Certification Scheme, the UK standard for small-scale renewable installations and the people who fit them. It matters for one practical reason: most export tariffs require your installation to be MCS-certified before they pay you for exported energy, and every system we install is commissioned by our MCS-certified teams, so the certificate comes as part of the job.
Which areas do you cover?
England, Scotland and Wales: our teams install nationwide. Every county has its own page with local solar figures, and the coverage map takes you straight to yours.
