As energy prices continue to rise, many UK households are looking for ways to take back control. One question we hear time and again is,
“Is battery storage worth the investment?”
The short answer? Yes, now more than ever! The long answer? Still yes, but let’s break it down. So, whether you’re a solar veteran or just starting your journey toward greener living, battery storage offers many advantages that make a real difference to your home, your bills and your carbon footprint.
Is Battery Storage Worth Adding to your Solar PV System?
If you already have solar panels, you’re already enjoying the benefits of clean, renewable energy. But without a battery, much of the electricity generated during daylight hours goes unused, exported back to the grid rather than powering your home.
Thanks to financial incentives like the Smart Export Guarantee, you do get paid for the energy you export back to the grid. But what if you could store that energy and use it when it really counts? Like after dark, during peak times or during a power cut? That’s where battery storage comes in! Here’s a closer look at the benefits:
1. Backup Power During Outages
No one wants to be left in the dark. Home batteries like the Tesla Powerwall provide reliable backup during grid outages, keeping essential appliances like fridges, lighting, or medical equipment running when you need them most.
This added resilience can be a game-changer in rural or remote areas of Scotland, where outages are more common and longer-lasting.
2. Lower Energy Bills
With the rise of time-of-use or dynamic tariffs, you can store energy when it’s cheapest (off peak) and use it when rates are higher. You can even be paid to use electricity on these tariffs, known as Negative Pricing!
Combine a battery with smart off-peak appliance use, and you’ll see some serious savings.
3. Increased Energy Independence
Without a battery, most homes use around 30–40% of the solar energy they generate. Add a battery and this can jump to 60–80%, allowing you to store excess solar generation and use it when it’s needed most.1
4. Environmental Impact
Battery storage helps you make the most of your renewable energy and further reduce your carbon footprint. By storing clean solar energy for later use, you cut down on the need for fossil-fuelled electricity from the grid, especially at night when demand is high.
5. Easy Retrofit for Existing Solar PV Systems
Already have solar panels? Great news! Most systems can be retrofitted with battery storage. Our experienced team will assess your setup, recommend the best solution, and guide you through the process from start to finish.
Is Battery Storage Right for You?
Battery storage isn’t a one-size-fits-all solution. That’s why we take time to understand your home, energy habits, goals and budget to help you make an informed choice that’s right for you (not one that suits us best).
But if you’re:
- Looking to increase your energy independence
- Concerned about power cuts
- Wanting to get the most from your solar investment
- Keen to reduce your bills and reduce carbon emissions
…then battery storage could be a perfect fit.
