Battery Storage Systems: The Essential Addition to Your Solar Panel Installation

As solar panel technology continues to advance, battery storage systems have become an increasingly important addition to solar panel installation in the UK. 

In this article, we’ll take a closer look at what battery storage systems are, why you need them when fitting solar panels, and the benefits of these innovative energy storage solutions.

What is a battery storage system?

A battery storage system is a technology that stores excess energy produced by solar panels during the day. Which can then be used at night or during times when the sun is not shining. 

The system typically consists of a battery pack, a battery management system and an inverter that converts the stored DC energy into usable AC energy.

Why do you need a battery storage system when fitting solar panels?

The primary reason to add a battery storage system to your solar panel installation is to maximise the efficiency of your solar energy production.

Without a battery storage system, excess energy produced by your solar panels during the day is fed back into the grid, with no benefit to you as the producer, other than payments received for selling the electricity back to the grid. 

With a battery storage system, you can store this excess energy for later use, reducing your reliance on the grid and maximising your savings.

This is particularly important if you work away from home during the day/sunlight hours, and therefore would not use the electricity generated from your solar panels.

Can I get a solar battery only package if I already have solar panels fitted on my home?

If you already have solar panels installed on your property, it’s still possible to add a battery storage system to your existing setup. At Eclipse Energy, we offer battery storage as a standalone package for those who already have solar panels installed. This package includes a brand new inverter, which is required to ensure that the DC electricity produced by your solar panels can be stored in the batteries and later converted into AC electricity for use in your home. 

By adding a battery storage system to your existing solar panels, you can enjoy the benefits of a complete solar and battery storage system, without the need to install new panels.

What are the benefits of battery storage?

  1. Cost Savings: One of the main benefits of battery storage systems is that they can save you money on your energy bills. By storing excess solar energy for later use, you can potentially eliminate your energy bill entirely.
  2. Energy Independence: Battery storage systems can also provide energy independence for homeowners and businesses. By producing and storing your own energy, you can reduce your reliance on the grid and potentially even become completely energy self-sufficient.
  3. Environmental Benefits: Battery storage systems can also help reduce your carbon footprint. By using stored solar energy instead of relying on energy generated from fossil fuels, you can help reduce greenhouse gas emissions and contribute to a more sustainable future.
  4. Increased Energy Efficiency: By storing excess solar energy, battery storage systems can increase the overall efficiency of your solar panel installation.

How much battery storage do I need?

The amount of battery storage you need depends on your energy usage and how much you want to rely on the stored energy. A general rule of thumb is to have a battery that can store enough energy to power your home for one to two days.

What size battery storage do I need?

The size of the battery storage you need depends on your energy usage and the size of your solar panel system. Generally, a battery with a capacity of 5-10 kWh is suitable for most homes, but larger homes or those with higher energy usage may require a larger battery.

How does battery storage work?

Battery storage systems work by storing excess energy produced by solar panels during the day and releasing it when needed, such as at night or on cloudy days. The battery stores the energy as DC power, which is then converted to AC power for use in your home.

Why should you get a solar and battery package together?

If you’re considering adding both solar panels and a battery storage system to your home, you should get them installed together as a package. This is because you may be able to save money on VAT.

In the UK, solar panels are currently eligible for a reduced VAT rate of 0%. Whereas only installing a battery storage system does not qualify for the reduced rate VAT. Therefore, if you were to add a battery storage system later on, you would likely have to pay the standard VAT rate of 20%. 

By getting the solar and battery package installed together, you can take advantage of the reduced VAT rate for both components, saving you money in the long run.

How much does a battery storage system cost?

The cost of a battery storage system varies depending on the size and type of battery, as well as installation costs. On average, a basic system can cost £5,000, which includes a new inverter.

What is an inverter and how do you use it in conjunction with solar panels and battery storage?

An inverter is a device used in conjunction with solar panels and battery storage systems to convert the DC (direct current) electricity produced by the panels and stored in the batteries into AC (alternating current) electricity that can be used to power your home. 

This is because most home appliances and devices operate on AC power. The inverter is responsible for regulating the flow of electricity between the solar panels, batteries and the grid, ensuring that your home has a constant supply of energy. 

It also ensures that any excess electricity generated by your solar panels is fed back into the grid, enabling you to receive credits or payments for the surplus energy. Inverters are an essential component of any solar and battery storage system, allowing you to make the most of the energy produced by your panels and batteries.
