Solar Battery Storage (No Solar Panels Needed)
Ace Energy are solar battery storage system installers based in Shaftesbury, fitting battery storage across Dorset and Wiltshire, whether or not you already have solar panels. A lot of homeowners assume a battery is only worth having alongside solar PV, but that’s not the case. A standalone battery can be charged from the grid overnight on a cheap tariff and then used to power your home during the day, cutting your electricity costs without a single panel on your roof.
If you’ve already got solar, a battery lets you store the electricity you generate but don’t use straight away, so you can run more of your home on your own power instead of exporting it cheaply and buying it back later at a higher rate. Either way, we’ll design a system around how your household actually uses energy.

You don’t need solar panels for this
A solar battery storage system can be installed entirely on its own. It charges from the grid during off-peak hours and powers your home at peak times, helping you avoid the most expensive part of the day for electricity.
How Battery Storage Works Without Solar Panels
This is sometimes called load shifting. Most energy tariffs charge more for electricity at certain times of day, usually early morning and early evening when demand is highest. A standalone battery charges up overnight when electricity is cheapest, then your home draws from the battery instead of the grid during those expensive peak hours.
You don’t need to change how you use electricity day to day. The battery does the work in the background, charging when rates are low and discharging when rates are high. If you’re on a time-of-use tariff such as Economy 7 or one of the newer smart tariffs, the savings can be significant, and the system pays for a portion of itself through reduced bills alone.
If a power cut hits, a battery with the right setup can also keep key circuits running, which is worth bearing in mind if you live somewhere rural where outages tend to last longer.

Benefits of Solar Battery Storage
At Ace Energy, we combine technical expertise with genuine local experience.
-
Lower bills without solar panels
Charge from the grid when electricity is cheap and avoid drawing power during expensive peak periods.
-
0% VAT
Standalone battery installations currently qualify for 0% VAT, the same as batteries installed alongside solar panels. This applies until 31 March 2027, after which the rate is due to rise to 5%.
-
More from your existing solar panels
If you’ve already got solar PV, adding a battery means you use more of the electricity you generate yourself, rather than exporting it for a low rate and buying it back later.
-
Backup power
Selected systems can keep essential circuits running during a power cut.
-
Future flexibility
A battery installed now can usually be added to or paired with solar panels later, if that’s something you want to add down the line.
Types of Battery Storage We Install
Standalone battery storage
Installed on its own, with no solar panels required. Charges from the grid on a cheap tariff and discharges during peak hours. The most straightforward option if you want to cut your bills without taking on a full solar installation.
Retrofit battery storage
If you already have solar panels, we can add a battery to your existing system so you’re storing and using more of your own generated electricity instead of exporting it.
Integrated solar and battery systems
For anyone considering both solar panels and battery storage from scratch, we design and install the two together as a single system, sized around your roof and your household’s energy use.
Our Installation Process

1. Free survey and consultation
We look at your current electricity usage, tariff and (if relevant) your existing solar setup to work out what size and type of battery suits your home.
2. System design and quote
You’ll get a clear, no-obligation quote covering the battery, inverter (where needed) and installation costs.
3. Installation
Most domestic battery installations take a day, carried out by our qualified, MCS-certified team.
4. Commissioning and handover
We test the system fully and talk you through how to get the most from it, including any app or monitoring setup.

Frequently Asked Questions
Here are answers to some of the most common questions we get asked by our Dorset based customers.
Do I need solar panels to install a battery storage system?
No. A solar battery storage system can be installed as a standalone unit with no solar panels at all. It charges from the grid during off-peak hours and powers your home at peak times, helping you save money regardless of whether you generate your own electricity.
How does battery storage save me money without solar panels?
By charging from the grid when electricity is cheapest, usually overnight, and then using that stored power instead of buying electricity at peak rates. This is known as load shifting and works well with time-of-use tariffs.
Is battery storage eligible for 0% VAT?
Yes. Standalone battery installations currently qualify for 0% VAT, the same as batteries installed alongside solar panels. This applies until 31 March 2027, after which the rate is due to rise to 5%.
Can I add a battery to my existing solar panels?
Yes. We regularly retrofit battery storage to existing solar PV systems, allowing you to store and use more of the electricity you already generate instead of exporting it.
How long does a battery storage installation take?
Most standalone domestic installations take around a day, depending on the system size and any electrical work needed.
Will battery storage work during a power cut?
Selected systems can be set up to keep essential circuits running during a power cut. This depends on the system and setup, so it's worth raising during your survey if backup power matters to you.
