For a long time, the UK has watched other parts of Europe adopt plug-in solar, while our own regulations made it difficult to introduce. Countries like Germany and the Netherlands have embraced small-scale balcony systems, giving people an easy way to generate their own electricity.

That is now starting to change.

The UK government has confirmed updates to the G98 distribution code and BS 7671 wiring regulations, allowing small plug-in solar systems under 800W to be connected to standard household sockets. This is a positive step forward, making solar more accessible than ever before.

But while plug-in solar opens the door for more people, it’s important to understand where it fits and where a full solar installation still offers far greater benefits.

What Is Plug-in Solar?

A plug-in solar system is typically made up of one or two panels connected to a micro-inverter. It converts the energy from sunlight into usable electricity and feeds it directly into your home through a standard socket.

These systems are:

• Small in size, usually between 400W and 800W
• Portable and easy to move
• Suitable for balconies, patios or garden walls

For renters or properties where rooftop solar isn’t possible, this can be a good entry point into renewable energy.

What Can You Expect to Save?

Plug-in solar can help reduce your electricity bills, but it’s important to keep expectations realistic.

Typical savings are:

• Around £70 to £110 per year for an 800W system
• Lower savings for smaller setups

While this is a helpful contribution, it’s relatively small compared to what a full solar system can achieve.

Where Full Solar Installations Really Stand Out

This is where it’s worth looking at the bigger picture.

A full rooftop solar installation can:

• Generate significantly more electricity for your home
• Power a much larger proportion of your daily usage
• Work alongside battery storage to store excess energy
• Allow you to export energy back to the grid and earn from it
• Provide far greater long-term savings

For homeowners with suitable roof space, a full solar system is still by far the most effective way to reduce bills and gain energy independence.

Plug-in solar is a useful option, but it is not a replacement for a properly designed solar PV system.

Do You Still Need an Electrician?

Even though plug-in solar is moving towards a simpler setup, there are still situations where professional advice is important.

You should speak to a qualified electrician if:

• Your consumer unit is older or already at capacity
• You’re unsure about the safety of your existing wiring
• You want to add battery storage
• You’re considering upgrading to a full solar installation

Getting this right from the start ensures safety, compliance and long-term performance.

Thinking Beyond Plug-In Solar

For many homeowners, plug-in solar is just the starting point.

We regularly speak to customers who begin with the idea of a small system, but quickly realise that a full installation offers:

• Better return on investment
• Greater energy savings
• More control over energy use
• Long-term future-proofing

As experienced solar installers across Devon, Cornwall, Somerset and Dorset, we can guide you through both options and help you decide what’s right for your property.

Our Approach

At Electrix, we’ve been installing solar PV systems and renewable technologies for over 20 years. We understand how to design systems that work in the real world, not just on paper.

Whether you are:

• Exploring plug-in solar
• Looking to add battery storage
• Planning a full rooftop installation

We can provide honest advice, a proper assessment of your property, and a solution that fits your needs.

Is Plug-in Solar Right for You?

If you’re renting, live in a flat, or don’t have suitable roof space, plug-in solar is a positive step and a great way to get started.

If you own your home and have a suitable roof, it’s worth looking at the bigger picture. A full solar and battery system will deliver far more value over time.
