Why add a solar battery?
A battery stores the solar energy you don’t use in the day, so you can use it later when your home needs it. It reduces the amount you buy from the grid and helps smooth your bills through the year, even in winter when solar output is lower.
How does a battery help you save money?
You use more of your own solar power, cutting paid-for electricity. You can also charge at cheaper off-peak prices and run your home from stored power at peak times. Some tariffs also pay you for energy sent back to the grid.
Choosing the right battery size
The right size depends on how much energy your home uses. Most homes need one or two units, while higher-use homes may need more. Our team checks your usage patterns and solar output to size the system correctly, with room to expand later if needed.

Nothing changes with your energy use or bills. You stay linked to your current supplier and whatever price changes come your way. Many people decide to explore solar once they realise they are paying for power they could generate themselves. Waiting simply means those costs continue, and you won’t start saving until you do go solar.
Yes. Solar panels work from daylight, not direct sunlight, and the UK gets more than enough across the year for systems to perform well. Output is higher in spring and summer, but panels still produce energy on cloudy days and during the winter months.
Adding a battery can make a big difference in darker seasons. It lets you store any surplus energy made during brighter periods of the day and use it later, such as in the evening when usage is higher. This helps smooth out the natural changes in winter output and gives you better use of the energy your system produces all year round.
Panels on your roof turn daylight into electricity. This passes through an inverter, which changes it into the type of power your home uses. Your house uses this energy first, cutting the amount you buy from the grid. If you add a battery, any extra power can be stored for later, which helps you make the most of the energy you produce each day.
Higher gas prices, world events, and shifts in supply all feed into the cost the UK pays for power. These pressures flow through to household bills because much of the country still relies on gas-fired power stations. As a result, many people look for ways to reduce how much of their energy comes from the grid and protect themselves from price swings in future.
