Do I need to register it?
Yes — register your device before you switch it on.
Registering tells your local electricity network operator that a plug-in solar device is being used at your address. You do it online at myplugin.solar, the official portal run by the Energy Networks Association, and it only takes a few minutes.
It’s a legal requirement in England, Scotland and Wales. You can only register a device that’s on the approved list, so it’s worth checking a system’s status before you buy it.
You’ll need
An email address
Your home address
Your device’s make and model
A device on the approved list
Who registers what
Two registrations — only one is yours
“Registration” gets used for two different things, which is why it’s easy to mix them up.
1 · The manufacturer
Gets the product approved
A plug-in solar device has to be tested against the government’s product specification. Approved devices are listed on the Energy Networks Association’s register — the register WattVerdict checks every day.
2 · You
Registers the device at home
Once you have a device and know where it’ll be installed, you register it at myplugin.solar. The portal then notifies your network operator for you.
Step 2 depends on step 1: the portal only lets you choose from approved devices.
Step by step
How to register
01
Verify your email
Go to myplugin.solar, enter your email address and confirm it with the one-time code you’re sent.
02
Confirm your address
Enter your postcode and pick your address from the list.
03
Choose your device
Select your device from the list of approved plug-in solar devices.
04
Submit
Check your details and submit. The portal sends the notification to your network operator automatically.
Register once you have the device and know where it’ll be installed — and before, or at the time of, switching it on for the first time. Not sure the socket you’ve chosen is suitable? See whether you need an electrician.

Common questions
Can I register more than one device?
No. Each household can have one plug-in solar device, with a maximum output of 800W, installed at any one time.
My device isn’t on the list. What should I do?
It may still be going through assessment — the portal suggests checking again after a few days. You can also look up a device’s current status on our Compare page.
What happens after I register?
The portal notifies your network operator that a plug-in solar device will be used at your address. Your details are shared with your network operator only, not with other companies.
Can I replace my device later?
Yes. Register the new device the same way, through the portal.
Do I need to fill in a G98 form?
Not for a qualifying plug-in solar device using the dedicated plug-in route. Register the device through myplugin.solar instead. G98 still matters in the background — compliant plug-in products are type-tested and listed through the relevant ENA framework — but you don’t complete the normal G98 paperwork for this type of installation.
Does this cover plug-in batteries?
No. The legal definition of a plug-in solar device excludes equipment designed to store electricity taken from your home’s supply, so plug-in batteries aren’t covered by this route.
What about Northern Ireland?
The Great Britain plug-in solar route described on this page applies to England, Scotland and Wales. Northern Ireland has separate connection requirements under G98/NI. Check the current requirements with NIE Networks before buying or connecting a system.
