Solar Battery » Features & Benefits

There are two ways to charge your Moixa Battery with guaranteed savings

Solar energy storage

Solar energy storage

Your solar panels will work through the day to power your home. Any excess energy will charge your Moixa Smart Battery, ready to be used for free in
the evening and through the night.

Time of use charging

Time of use charging

In addition to charging from your spare solar energy, the Moixa Smart Battery can be charged when grid electricity is cheap, for example if you have a time of use tariff. We can set a charging plan for you to take advantage of your tariff, charge cheaply overnight and then use it the next day.

Solar PV: Power up during daylight

Take advantage of the daylight hours to produce electricity to power your home.

  • Great investment
  • 25-year performance guarantee
  • Year-round power generation
  • Save up to 50% on your energy bills

Moixa Smart Battery: Save it for later!

The Moixa Smart Battery allows you to store electricity charged from your solar panels, rather than sending spare solar energy back to the grid.

  • Can be added to existing solar panels
  • Store unused solar electricity to power your home in the evening
  • Charge your Smart Battery from the grid with an off-peak tariff like Economy 7
  • Compact size (2kWh & 3kWh: 50.5 x 34.5 x 24.5 cm, 4.8kWh: 77cm x 52.5cm x 20cm).
  • Ask us about our flexible payment options

Moixa Dashboard: Guiding you to the biggest savings

Take advantage of the personalised Moixa Dashboard, offering a range of live data regarding your energy generation and consumption.

  • Provides 24/7 system monitoring in order to ensure optimal performance at all times
  • GridShare software evaluates your home’s energy profile and continually generates a personalised charging plan for the battery which is optimised to save money for your household

Flexible payment options helps make solar energy available to everyone

We want to introduce as many people as possible to the green energy revolution. That is why we are keen to offer varied payment option to suit every pocket.

Benefits of flexible payment options:

  • Choose the best way to pay.
  • Spread the cost while enjoying your savings immediately.
  • Use renewable energy from day one and reduce your dependency on the grid!

£123 per month typical payment for 2kWh battery.


Payment structure depends on exactly which product you purchase.

We will discuss your energy needs and the nature of your property in detail over the phone to make sure you get the ideal fit.

Here’s an example of how the flexible payment terms could work in practice:

  • You’re quoted £3450 for a 3kWh Moixa Smart Battery – one of our most popular options (inc. VAT & installation)
  • You pay a 50% deposit of £1725, followed by 12 monthly payments of £143.75 to settle the original balance.

Once that initial year of payments is over, you’ll be making those ongoing savings for years to come; solar storage is here to benefit you for the long haul!

Getting a solar and battery bundle and prefer not to pay 50% deposit? With a balance reducing loan you can get your system installed from as little as £100!

In addition to being able to spread the cost of your Moixa Smart Battery purchase, you will also gain access to your personalised Moixa Dashboard that allows you to track details such as your energy generation and home energy usage. It will also factor in insights such as upcoming weather forecasts to maximise your solar battery’s productivity and maximise the savings you make. This will allow your savings to increase even further over time.

When it comes to applying for our flexible payment options, the process is simple.

Solar energy may seem like a complex industry, but we don’t see any need to complicate the process of getting you the energy savings – and financial savings – that you’re signing up for. When purchasing a Moixa Smart Battery on flexible payment terms, our process is fairly straightforward:
