Solar Battery Energy Storage

Power your home with solar energy even after dark

The majority of homes use the least amount of electricity during the day, because that’s when most homes stand empty. Unfortunately, this also happens to be when solar panels generate the most amount of energy, energy which is often not fully utilised. By adding a battery to a solar PV system, you can store any excess energy captured during the day, then you can switch to battery power at night when your solar panels are no longer able to draw energy from the sun.

The Benefits:
  1. Solar power day and night
  2. Turn excess energy into stored energy for later use
  3. Maximise your Solar energy potential
  4. Reduces your reliance on the grid
  5. Potential to earn money by selling excess energy back to the grid
  6. Detect power outages from the grid to automatically provide your home with back-up power
  7. Creates a clean, renewable energy source

Home Battery Energy Storage

Some batteries can be used without Solar PV

Some batteries are suitable for use even when you don’t have solar panels. They’re designed to store energy from the grid during the cheapest “off-peak” times of day, so you can power your home for less at peak times of the day when the cost would usually be at it’s highest.

But if you’re thinking of installing Solar PV in the future, we can advise you on the best options to future proof your energy storage system.

  1. Store energy produced at the cheapest time of day for use at peak times – saving you money
  2. Maximise your energy saving potential
  3. Potential to earn money by selling excess energy back to the grid
  4. Some batteries can detect power outages from the grid to automatically provide your home with back-up power

Frequently Asked Questions

Solar Batteries and Home Energy Storage Solutions

No you don’t need Solar PV to benefit from a home battery energy storage system. We offer a range of battery options which are suitable for use in homes with or without Solar PV.

But if you’re thinking of installing Solar PV in the future, we can advise you on the best options to future proof your energy storage system.

We offer different battery solutions as an integral part of any new Solar PV installation, as we believe battery storage is the key to maximising the energy efficiency of your solar PV system.


Most solar batteries should last around 10 years, but it depends on the type of battery you choose and the amount of usage during it’s lifetime.

All batteries come with a manufacturers warranty. The exact length of warranty depends on the type of battery chosen.


As part of our home survey, we’ll discuss the most suitable locations for your battery. We usually aim to install it indoors, close to your consumer unit, such as in a utility room, a large enough cupboard or under the stairs. But if we can’t find a suitable place inside, it’s possible to install outside as long as there’s a sheltered spot where it isn’t exposed to direct sunlight or rain, with some kind of roof/overhead cover.

This depends on the manufacturer, power and size of the battery you choose.

The actual size of a battery ranges from approximately

Height: 620 mm – 1150 mm

Width: 480 mm – 755 mm

Depth: 155 mm – 220 mm

We will help you decide on the best location for your battery/batteries as part of our home survey and quotation, as you will also need to allow for clearance space around the battery/inverter, as per the manufacturers specifications.
