Domestic Energy STORAGE

Store any surplus energy for later use with S.P.P UK’s battery storage systems. Save money on your home energy bills, reduce your use of carbon loaded electricity, escape the ever-increasing high energy tariffs.

A domestic battery storage system allows you to save your surplus self-generated solar PV energy for use in hours of darkness around your home.

Our long-established network of professionals has allowed our team to develop expertise in the application of Lithium-ion battery storage systems. S.P.P UK install only the best brands and types of battery storage equipment to suit your needs. With App integrated technology, meaning it is even easier to view how you use energy around your home whilst easily controlling your energy storage system from anywhere in the world.

Normally, self-generated solar power will be used instantaneously throughout your home, otherwise any excess energy is released back to the grid. However, with an energy storage system you can store that excess energy for later use, this then reduces your reliance on costly power imported from the grid. Your stored self-generated solar electricity can then be called upon as required at anytime, therefore reducing your expenditure on costly imported power.

Energy storage systems can be installed as a retrofit option or at the same time as your new solar PV array. If your home electricity tariff is cheaper in the evening you could use this cheaper imported energy to charge your batteries for later use when your energy tariff is at its peak.

Frequently Asked Questions

How does it work?

When your solar PV system generates excess energy, where it is supplying all of your home load and then sending energy to the grid, this energy will then be stored in a battery bank and prevent your self generated energy escaping back to the grid. This stored energy can then be used when your demand is greater or in hours of darkness.

What battery do you use?

We use a Lithium-ion battery in our energy storage systems. The Lithium-ion battery will give you a far greater performance, a longer lifespan and a better reward on your investment.

What happens if I’m not at home during the day?

If you are not at home during daylight hours, your solar PV will continue to run your homes energy demand and charge your energy storage system to 100%, ready for when you are home in the evening. This means you can still benefit from green self-generated energy at night time when your solar PV is not generating.

What is the lifespan of the battery system?

Generally, This is dependent upon the charge cycle of the energy storage system. Lithium-ion batteries have a 10-15 year warrantied lifespan. For the best possible aftercare we recommend regular health checks and a full maintenance program.

What happens to excess energy when the batteries are full?

When your batteries are full and your Solar PV is generating more energy than required in your home, the excess energy is then exported back to the grid. They key here is that the system will always make sure excess energy is used to fill the batteries before exporting to the grid. Once full, all excess energy can be exported, where you are eligible to claim payment from an SEG distributor. Call our friendly experts to find out more on the SEG scheme.
