Maximum returns
Battery storage stores electricity for your home to use later — either charged up during cheaper off-peak times, or filled with excess solar power during the day.
Paired with solar, it captures the surplus your panels produce that you’re not using in the moment (which would otherwise be exported for a fraction of its worth) so you can run your home on it after dark instead.
Without solar, a battery can still charge overnight from the grid at cheaper rates and discharge during the day when electricity costs more, with the added benefit of backup power during an outage.
Every home is different, so we size each battery storage installation around your actual usage and, where applicable, your solar generation — giving you a system built to pay for itself.

Why homeowners add a battery
MAX Free Electricity
Your panels charge the battery during the day. When it's dark and generation drops, your home then draws free energy from the battery first, the grid is the last resort, not the default. Maximising your savings.
Price Protection
Most solar panel owners are still sending a third to half of what they generate straight back to the grid, then buying it back at full rate a few hours later. Your battery stores this power for later use, so you're not paying peak electricity prices.
Cleaner Energy
Store the clean energy your panels generate, so you can power your home on renewable energy around the clock, reducing your carbon footprint, not just your bills.
Energy Independence
Store more of what your panels produce, rely less on the grid, and shield yourself from ever-rising energy prices — putting you in control of your own energy supply.
What to expect
Our team will assess your household energy usage alongside your actual solar panel output — or projected figures if you’re having panels installed at the same time — to recommend the right battery size for your home.
We work with the best solar battery brands, chosen for their reliability, efficiency, and proven performance in UK conditions.

Your questions answered
Common questions
If your question isn't listed, please reach out to us below.
What is a solar battery storage system?
A solar battery storage system captures the free electricity your solar panels generate during the day and stores it for use later when your panels aren’t generating power (during the dark hours). Instead of sending unused energy back to the grid for a fraction of what it’s worth, you keep it and use it yourself.
How much does a home solar battery system cost?
Battery systems in the UK typically range from £2,000 to £6,000 depending on capacity and brand. Most homeowners opt for a 5–10kWh battery, with 10kWh systems being the most popular for whole-home coverage. The right size depends on your energy usage and the output of your existing solar panels.
What size solar battery do I need to power my house?
For most UK homes, a 5–10kWh solar battery is sufficient to cover evening and overnight energy use. A 10kWh solar battery storage system will typically power lighting, appliances, and heating controls throughout the night. We can assess your exact requirements based on your solar panel output and household consumption.
Can I add a battery to my existing solar panels?
Absolutely. Adding a battery to an existing solar system is one of the most popular upgrades we carry out. If your panels are already generating more than you use during the day, a battery ensures that surplus energy isn’t wasted, it’s stored and used when you need it most.
Can a solar battery charge my electric vehicle?
Yes absolutely — a solar battery can be used to charge your EV, allowing you to run your car on clean, home generated energy rather than grid electricity.
Paired with a smart EV charger, you can schedule charging to draw from your battery automatically, reducing both cost and carbon emissions.
Ask us about adding an EV charger to your installation if you don’t have one already.
How do solar batteries improve energy efficiency?
Solar batteries improve energy efficiency by maximising the use of the renewable energy you already generate. Without storage, much of your solar output is exported to the grid during the day while you buy electricity back at full price in the evening. A battery closes that gap, you use more of what you produce, reducing waste and cutting bills.
What is the best solar battery brand in the UK?
There are several leading solar battery brands trusted by UK homeowners, including Tesla, SolarEdge, Huawei, EcoFlow, Duracell Energy, Alpha ESS, Sunsynk, Sigenergy, and Anker.
The best solar battery for your home depends on your system size, energy usage, and budget, our team will recommend the right option for you.
Can I have a battery storage installation without having solar panels?
Yes. Battery storage installation doesn’t require solar panels — a home battery can be installed as a standalone system, charging from the grid during cheaper off-peak hours and powering your home when electricity prices are higher. Standalone battery storage installation is one of the fastest-growing choices among UK homeowners, and qualifying systems currently benefit from 0% VAT. If you add solar panels later, your battery can easily be integrated into the system.
Are Finance options available?
Yes, finance options are available for your battery storage installation. Project Heating Solutions Limited is authorised and regulated by the Financial Conduct Authority.
