Solar Battery Storage — Use Your Energy When You Need It Most
Solar panels generate most of their power during daylight hours. But most households use the majority of their electricity in the evening. Without a battery, you’re exporting cheap solar energy to the grid and buying expensive grid electricity back at night.
What Is Solar Battery Storage?
A solar battery stores the excess electricity generated by your solar panels during the day. That stored energy is then available for use at night, on cloudy days, or during grid outages.
Combined with a solar panel system, a well-sized battery can reduce your reliance on the grid to near zero — meaning your energy bill drops significantly year-round, not just in summer.
Benefits
Benefits of Adding Battery Storage
Use your own solar energy 24/7 — not just when the sun is shining
Reduce grid import costs significantly, especially during peak evening tariff rates
Energy security — some batteries provide backup power during outages
Maximise your solar ROI — pair battery storage with time-of-use tariffs like Octopus Go for additional savings
Future-proof your home — batteries increase the value of your solar investment

Can I Add a Battery to an Existing Solar System?
Yes. If you already have solar panels, we can assess your current system and recommend a compatible battery. Not all inverters are battery-compatible, but in most cases, a retrofit solution is available.
We’ll carry out a full assessment of your existing system during a free survey.
Costs
How Much Does Solar Battery Storage Cost?
Battery costs vary based on capacity (kWh) and brand. A 5–10 kWh battery suitable for most homes typically costs between £3,000 and £7,000 installed.
