Solar batteries store your energy for when you really need it.

Batteries are now installed alongside most of our solar PV installations and have taken some huge steps forward in recent years. Enabling you to store your free, renewable, electricity to use at night when the panels are no longer generating and combining with new tariffs from innovative electricity providers.

Batteries are the component we see the largest variation in cost and quality so we look at a large range to select the best options for different customer requirements.

What our Customers have to say

  • I was so confident in this company that gave me no hard sell… I went on holiday, upon returning everything was finished and tidy and clean, paperwork complete and sorted out with my power supplier. Excellent service and value.

    Paul Lewis
  • From start to finish we found Sunlight Future to be a very professional, helpful and friendly team. The system was very competitively priced (the best out of five quotes) and is working EXTREMELY well. Overall, we are very satisfied customers.

    Elizabeth Chapman
  • Service, price and professionalism come as standard from this company and they are a pleasure to do business with.

    Gill & Simon
  • I would like to say that I am very pleased with the installation, system and your system design. I would like to say that I would recommend Sunlight Future to anyone who is interested in solar.

  • I would highly recommend Sunlight Future to anyone thinking of solar energy and will use this company when I install solar hot water system.

    Adrian Pittard
  • The system has been working very well and after 6 months we are 15% ahead of the the figures we were predicting. It has been a pleasure doing business with Sunlight Future and I would recommend them to anyone wanting a solar pv system installed.

A well designed residential solar storage system should provide over 70% of your annual electricity requirement, allowing you to use what you produce, rather than the grid.

Reduce Your Bills

You won’t be caught short with a battery, which can use solar energy collected during the day to power your home at night. Also, during the darkest parts of winter you can save money by charging your battery at night when electricity is less expensive on off peak tariffs.

Reduced Environmental Impact

Particularly when used in combination with solar, energy can be captured and stored for later use, reducing dependence on the grid, and fossil fuels.

Energy Security

By reducing your dependence on energy from the grid you are insulating your home from wholesale energy price instability.


Monitor Your Energy

Keep track of how much energy you are using, and how much energy you are storing in your battery.


If the grid fails, you won’t. Some batteries can ensure that in the event of a power cut, your house will be powered by the electricity stored in your battery.

  • How a Battery Storage System works

    In a conventional solar pv system the house will use all the electricity produced from the panels before it imports electricity from the gird. If the panels produce more electricity than the house is using at that point in time it will export it to the grid to be taken up by other users.

    In a battery storage solar pv system, this extra power will be diverted to the battery bank in your house and stored to use later when your house requires more energy than the array can provide and at night when the solar pv is not generating.

    The wiring of the system is such that the house will use the battery power preferentially ahead of the grid (like conventional solar), thus saving you money as you no longer need to buy as much expensive electricity from the grid. You can use your free electricity that you have already generated instead!

    If the battery bank is full, and your house demand is being met by the solar, any excess generation will still be exported to the grid, as usual, so other users can benefit.

  • DC-Coupled vs AC-Coupled

    There are two types of battery storage solutions for solar pv arrays, DC-Coupled and AC-Coupled. All solar pv panels produce DC current and this is then changed to AC current by the inverter so the power can be used by the appliances in the house. As a result, there is a DC side and an AC side to a solar pv system. Whether a storage solution is DC-Coupled or AC-Coupled refers to which side of the inverter the battery bank is.

    In a DC-Coupled system the solar pv panels and the batteries are before the inverter and therefore the batteries can be charged directly from the panels at high efficiency as there are minimal losses. When power is required from the batteries the stored electricity then passes through the inverter to be used by the house just like normal power would from the panels.

    In an AC-Coupled system the DC current from the panels is changed to AC current by the inverter, this is then changed back to DC by a second inverter to charge the batteries. When power is required from the batteries the stored power is then passed back through the second inverter to become usable AC current again.

    The main advantages of an AC-Coupled system are that it is easily retrofit-able to any solar pv system and simple to install and does not require altering the solar pv system already installed.

    With a DC-Coupled system there may be a need for an inverter change to make sure it is compatible with the new battery system but having one inverter increases the efficiency of the whole system and saves space which is useful in many domestic situations. This is also a great option for a new solar pv installation.

  • Lithium Batteries

    There are two main types of batteries sold to work with solar pv systems. These are Lead-Acid batteries and Lithium-ion batteries. These two types of batteries work very differently and both have merits depending on the conditions and location of the solar system. For domestic on-grid systems Li-ion batteries represent the best solution:

    • High Energy Density (more energy per unit area)

    • High depth of discharge (DOD)

    • Higher continuous power output

    • Long battery life / high number of charge cycles

    • High efficiency between charging and discharging
