Can You Run Solar Panels Without Batteries?

If you’re exploring solar energy options for your home or property, you’ve probably wondered: can you run solar panels without batteries? It’s a valid question, especially for UK homeowners and landlords weighing up the need for solar battery storage as part of their system. 

This guide provides a deep dive into this topic, helping you make an informed decision about solar power and whether battery storage is right for you.

Can You Run Solar Panels Without Batteries?

Yes, you can run solar panels without batteries, and in fact, many systems in the UK are installed without battery storage. These are known as grid-tied or on-grid systems. When your solar panels produce electricity, it’s used immediately in your home. 

Any excess is exported to the National Grid, and when the sun isn’t shining, your home draws electricity from the grid as normal.

This setup avoids the upfront cost of solar batteries and the maintenance that comes with them. However, there are important trade-offs to consider.

Key Advantages of Running Solar Panels Without Batteries

• Lower initial cost – You avoid the significant investment in battery storage.
• Simpler installation – Fewer components, less wiring, and shorter installation times.
• Reduced maintenance – Batteries require monitoring and eventual replacement, while a battery-free system is more hands-off.

Key Disadvantages

• No energy independence – You remain dependent on the National Grid, especially in the evenings and during power outages.
• Missed savings opportunities – You can’t store surplus solar energy for use during peak-rate periods.
• No backup power – Grid-tied systems shut off during a power cut, unless you have battery backup. If you’re concerned about this, learn more in our guide: do solar batteries work during a power outage?

When Does It Make Sense to Go Battery-Free?

For some homeowners or landlords, running solar without batteries is a practical first step into renewable energy, especially if:

• Your electricity usage mostly occurs during daylight hours
• Your property qualifies for the Smart Export Guarantee (SEG) and you receive payments for exporting surplus power
• Budget is a key constraint in your renewable energy upgrade

However, as energy prices fluctuate and the value of stored power increases, many are now re-evaluating this approach.

Why You Might Want to Add Solar Battery Storage

Adding a battery to your system can make solar power even more cost-effective and practical. With a battery, excess energy generated during the day is stored for use at night or during a power outage.

A few compelling reasons to consider a battery include:

• Increased energy independence
• Reduced reliance on grid electricity
• Protection against blackouts
• Maximised return on your solar investment

And yes, you can add a battery to an existing solar system if this is something you’re considering.

Choosing the Right Battery: Size and Safety

If you’re thinking about battery storage, make sure you select the right size for your household needs. Our guide on what size solar battery you will need can help you make an informed choice.

Battery storage doesn’t come without risks, so safety is crucial. Rest assured, modern systems are built with robust protection standards. Learn more in our article: are solar batteries safe?

Making the Decision: With or Without Batteries?

Ultimately, whether or not to include a battery in your solar setup depends on your energy goals:

• Want to reduce your carbon footprint and make an eco-conscious change? Going battery-free is a good start.
• Want to maximise self-sufficiency and protect yourself from rising grid costs or outages? A solar battery is the way to go.

If you’re researching solar storage options, it’s worth exploring the different types of solar batteries available, as well as understanding how solar batteries work.
