*Increased Home Value

Dev Soly — Fri, 06 Jun 2025 15:25:21 +0000

*According to this report by energy transition consultancy Baringa Partners, emerging evidence suggests a house value increase of up to 16% for new build homes and a 2-3% value increase for existing homes with solar panels or heat pumps (versus like-for-like gas-heated homes).

When will my installers arrive?

Finnan Duddy — Thu, 24 Oct 2024 13:22:18 +0000

For solar panel installation, your installers will arrive promptly in the morning of the scheduled day between 8am and 12pm.

We always aim to complete installations within one day, but for larger projects we might take up to two days. As part of our commitment, our installers will also conduct a thorough site clean-up post-installation.

As battery installation is a smaller job, if you are just getting a battery, your installers will be in touch beforehand to inform you of the time of day that your battery will be installed, as this may be in the afternoon.

If there are any changes to the schedule due to unforeseen circumstances, we will let you know ahead of the installation.

What is the difference between DNO application and DNO commissioning?

Finnan Duddy — Thu, 24 Oct 2024 13:19:39 +0000

The DNO application is the initial request we submit to your local Distribution Network Operator (DNO) to approve the connection of your solar system to the power grid. This step ensures that your installation meets all local safety and electrical standards.

After your installation is complete, we enter the DNO commissioning phase. This final step involves the DNO testing your system to make sure it’s safe, fully functional, and won’t interfere with the grid. Once your system passes this check, it’s officially activated.

At this stage, you may also receive an Export Meter Point Administration Number (MPAN). This allows you to track the energy your system exports back to the grid. With this MPAN, you can sign up for an export tariff with your energy supplier and earn money for the excess electricity your solar system generates but doesn’t use.

In short:

DNO Application: Pre-installation approval.
DNO Commissioning: Post-installation validation.
MPAN Export: Lets you sell surplus energy back to the grid, providing potential extra income.

How do I find out which DNO application I qualify for?

Finnan Duddy — Thu, 24 Oct 2024 13:11:50 +0000

To find out which DNO application you qualify for, the process is determined by the size of your solar installation in kWh:

G98: For installations under 3.68 kW per phase (up to 11.04 kW for a typical 3-phase supply). These are generally smaller residential systems, and we don’t need to apply in advance. We notify the grid after installation.
G99 Fast Track: For systems between 3.68 kW and 7.36 kW per phase. This can often be processed within 14 days. However, this is not always the case as the DNO can be rejected.
G99 Standard: For larger installations over 7.36 kW or more complex systems. Approval for these applications can take between 28-60 days.

Our team will review your system’s specifications and handle the DNO application process for you.

How do I find my MPAN?

Finnan Duddy — Thu, 24 Oct 2024 13:10:31 +0000

Your MPAN (Meter Point Administration Number), also known as a Supply Number, is a unique 13-digit reference number for the electricity meter at your property.

It is essential for identifying your supply point when setting up an export payment for your solar energy. You can find your MPAN in one of the following ways:

On Your Electricity Bill: Look for a section labelled “Supply Number” or “MPAN” on a recent electricity bill. It’s often displayed as a series of numbers at the bottom or back of the bill.
Contact Your Electricity Supplier: If you can’t find a recent bill, you can call your electricity supplier directly. They’ll be able to provide your MPAN over the phone.
The National Grid’s MPAS: You can also find your MPAN by contacting the Meter Point Administration Service (MPAS) for your region. They can help locate your MPAN using your address details.

Depending on where you live in the country your number will be vastly different, however your starting two digits will always be between 10-23.

What will happen on installation day?

Finnan Duddy — Thu, 24 Oct 2024 13:09:54 +0000

Your installers will arrive between 8am and 12pm on your installation day.

They will start by talking you through your solar project and making sure everything is clear before getting to work on installing your system. The team will handle everything from electrical work to system testing.

Once everything is in place, they will get you set up on your system’s app, showing you exactly how to track your energy generation and usage. You’ll now be generating clean, solar energy and will start seeing savings on your energy bill immediately!

Before leaving, the team will clean up any debris and ensure your property is tidy. They’ll also be available to answer any final questions you may have.

What is my handover pack and when will I get it?

Finnan Duddy — Thu, 24 Oct 2024 13:09:34 +0000

Your handover pack is a crucial collection of documents you’ll receive after your solar installation. It can take up to 28 working days to arrive because it contains important certifications and approvals that need to be processed.

Here’s what’s included:

- Export Tariff Registration – The Distribution Network Operator (DNO) must approve and commission your system for grid export. This process, which allows you to earn money from surplus energy, can take up to 28 days.
- Warranties – Coverage details for your system and components.
- MCS Certificate – Verifies your installation meets high industry standards. Processing this certificate also takes up to 28 days as all aspects of the system are verified
- Electrical Safety Certificates
- Building Notification Certificate
- Maintenance Information
- Schematics – Diagrams of your system setup.

The MCS certification and DNO commissioning are the certificates that take the longest to process. Both require time to ensure that your system meets all safety, compliance, and performance standards.

When will my scaffolders arrive?

Finnan Duddy — Thu, 24 Oct 2024 13:07:25 +0000

Scaffolders will arrive at the property up to 7 days before installation is due to take place – this includes on the day of installation.

Please note, the scaffolding will remain in place for up to 14 days after installation. This is to allow us to monitor your system and quickly address any issues, should they arise, ensuring everything is running smoothly.
