Solar Panels & Battery Storage: Do You Need Both?

If you're considering solar panels for your home, there's another question you're likely to come across fairly quickly: do I need a solar battery too?

Solar panels and battery storage work brilliantly together, but they do different jobs. Understanding the difference can help you decide what is right for your home, your lifestyle and your energy usage.

At Primis Renewables, we help homeowners across Shropshire, Telford and Staffordshire find renewable energy solutions that work for their individual property, rather than taking a one-size-fits-all approach.

What Do Solar Panels Actually Do?

Solar photovoltaic (PV) panels generate electricity from daylight.

During daylight hours, the electricity generated by your panels can be used to power your home, helping to reduce the amount of electricity you need to buy from the grid.

But there's an obvious issue: your panels don't necessarily generate the most electricity at exactly the same time that you use the most.

That's where battery storage comes in.

What Does a Solar Battery Do?

A battery allows you to store electricity so that it can be used later.

For example, your solar panels may generate plenty of electricity during the middle of a sunny day when you're at work and your home is relatively quiet.

Instead of all of that surplus electricity being exported, a battery can store energy for you to use later – perhaps when you get home, cook dinner or settle down for the evening.

In simple terms:

Solar panels generate the energy. A battery gives you more control over when you use it.

Do You Have to Have a Battery with Solar Panels?

No.

Solar panels can be installed and used perfectly well without battery storage.

Whether adding a battery makes sense will depend on factors including:

• how much electricity your household uses;

• when you typically use it;

• the size of your solar PV system;

• your available budget;

• your current electricity tariff; and

• what you want to achieve from your system.

  
  

For some households, solar panels alone may be the right solution. For others, battery storage can significantly increase the amount of generated electricity they are able to use themselves.

Can a Battery Be Added Later?

In many cases, yes.

If you're considering solar now but aren't ready to invest in battery storage, talk to your installer about your future plans.

Designing the system with future battery storage in mind can make things easier if you decide to add one later.

Is Battery Storage Right for Your Home?

There's no universal answer – and that's exactly why getting the right advice matters.

A good solar installation shouldn't start with a product. It should start with your property, your electricity consumption and what you want your system to achieve.
