Solar Battery Storage Aberdeen
Your local MCS certified specialists for solar battery storage installation across Aberdeen and Aberdeenshire. Whether you're adding a battery to existing solar panels or installing a complete solar and storage system, we'll help you get the most from your renewable energy investment.
How Does Solar Battery Storage Work?
Solar panels generate electricity during daylight hours — but most households use the bulk of their energy in the morning and evening, when the sun isn't shining. Without a battery, that surplus daytime electricity is exported back to the grid at a relatively low rate, meaning you're not getting full value from your system.
A solar battery stores your surplus electricity during the day so you can use it in the evenings, overnight or on cloudy days — instead of buying it back from the grid at a higher rate. The result is a dramatic increase in how much of your own solar electricity you actually use, and a significant reduction in your energy bills.
Modern batteries can also be programmed to charge overnight using cheap off-peak electricity tariffs — such as Octopus Energy's Agile tariff — giving you an additional layer of savings even during periods of low solar generation.
- Without battery: use ~30% of solar electricity generated
- With battery: use 80%+ of solar electricity generated
- Average saving with battery: £840/year
- HES interest-free loan up to £15,000 available
New Installation or Retrofit — We Do Both
New Solar & Battery System
If you're starting from scratch, installing solar panels and battery storage together is the most cost-effective approach. We design the entire system — panels, inverter and battery — to work seamlessly together, maximising your energy generation and self-consumption from day one.

Already have solar panels? In most cases we can retrofit battery storage to your existing system. Depending on your current inverter setup, this may involve installing an AC-coupled battery or upgrading to a hybrid inverter. We'll assess your system as part of your free survey.
Solar Battery Storage Cost and Funding in Aberdeen
Solar battery storage typically costs between £2,000 and £6,000 depending on the capacity and brand of battery chosen. Installing alongside new solar panels is usually the most cost-effective approach, with combined systems typically ranging from £10,000 to £16,000.
All battery storage installations currently benefit from 0% VAT until March 2027. The Home Energy Scotland interest-free loan of up to £15,000 is also available for combined solar and battery installations, meaning you can spread the cost with no added expense over up to 10 years.
Frequently Asked Questions
Is solar battery storage worth it in Scotland?
Yes. Without a battery, most homes use only around 30% of the electricity their solar panels generate. Adding storage increases this to over 80%, with homeowners saving an average of £840 a year. Battery prices are now 40% cheaper than in 2022, making it a strong investment.
How long do solar batteries last?
Most modern lithium batteries last 10–15 years and come with a 10-year manufacturer warranty. After the warranty period, batteries typically retain around 80% of their original capacity, continuing to provide useful storage beyond that.
Can I add battery storage to my existing solar panels?
Yes — most existing solar PV systems can be retrofitted with battery storage. We'll assess your setup during your free survey and recommend the best option for your system.
Do I need solar panels to install a battery?
No. A standalone battery can be charged overnight using a cheap off-peak electricity tariff, saving you money even without solar panels. Many Aberdeen homeowners do this alongside smart tariffs like Octopus Agile.
Can I get a grant for battery storage in Scotland?
There's no standalone grant for battery storage, but the Home Energy Scotland interest-free loan of up to £15,000 covers combined solar and battery installations. All installations also benefit from 0% VAT until March 2027.
