If you are thinking of storing electricity from solar energy and looking for details on how long do solar panels store energy, then it may be a more straightforward answer than you would think. Solar panels themselves do not store energy; they generate electricity that you can use to power your home. If you want to store energy for future use, you do so by combining the solar panels on the roof of your home with a solar battery storage unit.

Here at Moixa, we provide the combined solar system as our standard option, as we understand how you can maximise the potential of solar energy to take back control of your energy production and consumption, lower your energy bills, reduce your carbon footprint, and even add money to the value of your property should you wish to sell or refinance in future.


Some key solar battery questions are covered in these guides:

How much money does a solar battery save?

How do solar batteries and solar panels work on cloudy days?

How much electricity does a solar panel battery system produce?


How do solar panels work in the UK?

Can you store electricity? If you are using solar panels only, then unfortunately not. That’s why Moixa has decided to sell and install a combined product and service of solar panels alongside a Moixa Smart Battery unit. This helps you utilise and elevate the best attributes of solar panels.

So, how do solar panels work in the first place? In the UK, more people over the last decade or so have started to install solar panels as they realise the potential for taking control of creating electricity. The solar panels have PV (Photovoltaic) cells within them to turn sunlight into electricity.

Now, in the first instance this means that you can connect the solar panels to anything that you wish to power, from a garden light in the back yard, to the garage, appliances in the utility room; anything across the home. During the daytime, this will mean that your house is powered by solar energy, but what happens with regards to solar energy when the sun goes down?

How do you store solar energy?

Can you store energy from solar panels? Yes, quite easily, and with Moixa we can help you fulfil that potential for your solar panels and power your home day and night.But how do solar panels store electricity? By connecting the Moixa Smart Battery to your system of solar panels, you can charge it up during the day, alongside whatever else you are powering using the solar electricity being created by the panels on the roof of the property.

When darkness falls, you can then access the electricity by using the solar battery, meaning that your home can continue to use solar power throughout the entire day and night! Another option with our flexible product is that you can charge up the Smart Battery, making major energy savings which are continually refined via the Moixa Dashboard system.

You can also make money via GridShare membership, as well as reducing your energy bills as you lower your reliance on traditional energy companies to power your appliances. All of Smart Battery units are compact and won’t look bulky or out of place wherever you choose to have them installed within the home. We offer 2kWh and 3kWh units – as well as our 4.8kWh on pre-order – ensuring that we cater to a range of solar energy needs.

How much does a Smart Battery cost?

As we stated above, we offer two (soon to be three) different types of Moixa Smart Battery. This, allied with the fact that different households will require different numbers of solar panels to be installed depending on the specific energy requirements of your home, is why we can’t just give you a definitive figure here and now.

Nor would we want to, as we understand that every customer is different to the next. If you visit our Receive a Quote page you can start to get an idea about what to expect, so we can get moving with discussing your specific energy needs and how we can help you. What we can do, however, is provide an overview of the general prices we offer:

  • For a 2kWp solar panel system and 2kWh solar battery (including full installation and VAT) = £4995

For your Moixa Smart Battery alone (including installation and VAT):

  • 2kWh = £2950
  • 3kWh = £3450

The average Moixa customer will require 14 solar panels hooked up to a 3kWh battery unit, coming in at a cost of around £9,000. What you should also remember is that all of our prices include not only VAT, but also installation. On top of this, we can offer flexible payment options to allow you to spread the cost onto more manageable terms, while gaining access to savings right away.
