What is solar battery storage?

solar battery

For the last 20 years, many areas in the UK have begun to see widespread use of solar panels powering homes during daylight hours. This is a great start, but batteries for solar panels advance this benefit much further.

The big difference between simply having solar panels on your roof, and having solar panel battery storage, comes in being able to store that energy to use later in the day, rather than as and when it is generated.

More importantly, the Moixa Smart Battery can be charged not only from the sun during the day, but also overnight when grid electricity is cheap, for example if you have a time of use tariff.

How do solar batteries work?

The biggest advantage of solar energy battery storage is in its ability to take the energy generated by solar panels during the day and store it to power your home in the evening and overnight. This is a revolutionary step forward, with Moixa Smart Battery as the UK’s leading Smart Battery company.

But how does it actually work?

Solar panels generate renewable energy during the day and this energy is used to supply electricity to your home. With energy prices constantly on the rise, it makes sense to try and use as much of the free electricity solar panels are producing as possible, instead of sending it back to the grid.

Battery storage makes this all possible. The excess energy your home is not currently using goes into charging your Moixa Smart Battery, so instead of sending the excess electricity back to the grid, you store it in a battery that can then discharge and power your appliances when the sun isn’t shining.

Using your Moixa Dashboard, you can gain access to a range of live data on your current energy consumption and charge level of your battery. We ensure 24/7 system monitoring for optimal performance.

Can I spread the cost of buying a solar battery?

Initial Outlay vs Ongoing Value

That all depends on exactly which of our solar batteries you purchase – remember we will discuss your energy needs and the nature of your property in detail to make sure you get the ideal fit – but here’s an example of how the flexible payment terms could work in practice:

  • You’re quoted £3,450 for a 3kWh Moixa Smart Battery – (inc. VAT & installation)
  • You pay a 50% deposit of £1,725, followed by 12 monthly payments of £143.75

Once the initial year of payments is over and you’ve settled your balance, you’ll continue to make ongoing savings for many years to come. With a 25-year warranty on solar panels, and 10-year warranty on a Moixa Smart Battery – extendable if you join GridShare membership – solar storage is here to benefit you for the long term.


How do I know which solar panel battery system I need?

home solar battery

There are various factors that go into determining your home energy profile. It depends on the size of your home, the number of people living within the home and your energy consumption patterns. Put simply, the more electricity you use, the higher the number of solar panels and larger the solar battery capacity you will need to install to best meet those needs.

Most homes in the UK require anywhere between 4 and 16 solar panels in order to meet the needs of their home. To give you an idea, at Moixa, our clients will most commonly choose 14 solar panels to install, alongside a 3kWh solar battery. A large home, with 4+ bedrooms and big family, obviously uses much more electricity than a single person living in a one-bedroom bungalow, however it’s also important to evaluate when the energy is being used and how much of it is consumed during the day vs. in the evening or at night.

Moixa evaluates all the aspects of your energy consumption, ensuring you get the correct number of solar panels and solar battery capacity, from our 2kWh, 3kWh and 4.8kWh (only for pre-order) Moixa Smart Battery options.

Get in touch for exact details on what each battery capacity can offer.

How do we calculate your solar battery requirements?

Calculate your Energy Profile

To accurately evaluate your battery size requirements, we need to understand your energy profile.

  • Step 1 in the process is getting your average daily usage in kWh, which can be done by taking your monthly (or quarterly) bill and dividing it by cost per unit.
  • Step 2 is understanding how much electricity the home uses in the day versus through the night.

On average, we see a split of around 60% day to 40% at night.

It is also important to keep in mind that for solar battery customers, their usage will often change to more day usage after solar is installed, as the customer should be putting their appliances on timers to run when solar is generating.

Match Your Profile to Our Range

Finally, we take the average daily use (kWh) and multiply by the percentage of ‘night use’, which then gives us rough overnight usage in kWh.

We match this to the capacity of our batteries i.e., an overnight usage of 2.7 kWh would make us suggest a 3kWh battery.

All our batteries are created with the UK customer in mind, making sure it fits the intensity of solar generation and energy consumption of the average UK household.

Can a solar battery really add value to a home?

Key benefits to consider

Having an effective solar panel battery system is not only good for you now, it also adds potential value to your home in the future. Should you decide to leave your solar battery and panels in place when you sell your home, there are a number of key elements that could make them an attractive prospect to many potential home buyers.

Control over energy bills

The first major reason that the value of your home could increase due to the installation of a solar battery is in taking charge of a home’s energy bills. Over the last few years, energy bills have continued to rise, and there is no sign that this is going to slow down or reverse any time soon. From day one of a solar panel battery system being installed, you will begin to see up to 50% reduction in energy bills. This aspect of solar batteries is obviously a very enticing to prospective buyers when it comes time to sell your home.

A glowing energy report

Solar panel installation can also help increase property value by helping to raise the grade of the EPC (Energy Performance Certificate) linked to it. Every single house in the UK has to have a valid EPC, with grades ranging from highest (A) to lowest (G). Solar panel battery system installation can improve an EPC rating by as much as two grades, which in turn can add real monetary value to a property.

How much energy does a solar panel battery system generate?

System size

Generation depends on many different factors, such as the number of solar panels you have installed at your property, the orientation of the panels and the number of daylight hours in your location. In general terms though, a 3kWp or 4kWp solar panel system will be able to produce enough electricity to help meet a considerable portion of the energy needs of a family home. For a smaller home, a 2kWp is much more suitable. However, the battery size also depends on the consumption patterns, because if you’re at home all day using the sun’s energy, even with a bigger system you may benefit more from smaller size battery, as you may not have a lot of spare solar.

Real life numbers

Take a look at real life appliance-based comparisons of our larger 4kWp solar and 4.8kWh battery systems. The following breakdown outlines the average level of solar energy you will generate over the course of a year. It will be enough solar energy to:

  • Enjoy 97,143 hours of power for a fridge, or
  • Continuously boil a kettle for 1,880 hours, or
  • Use the oven for 1,417 straight hours, or
  • Use the washing machine for 4,857 hours
