Technical review stage

Technical review stage is where you provide our technical team with specifications, data and documents regarding your property so we can address any issues before installation day.
What is the technical review stage and how long does it take?
 
The validation stage begins once you've submitted your technical review form, which includes important photos and details about your property.

It’s important to note that we cannot proceed with your project until this form is submitted. The sooner the form is completed, the sooner we can move forward!

During this stage, we review the information and photos you've provided to make sure everything is ready for your solar installation.

This process typically takes up to 3 business days, but if we need more information, it may take a little longer.

Once everything is approved, we’ll move forward with the next steps of your installation journey!

What information do I need to provide for the technical review stage?
 
The technical review form collects essential information to help us prepare for your solar installation. Here’s what you’ll need:
  • Photos:
    • Main service fuse (clear, unobstructed photo of fuse with all text and cables visible)
    • Electricity meter (including serial number) and its location (e.g., cupboard, external wall)
    • Roof(s) where solar panels will be installed (ensure tiles are clearly visible)
    • Wall(s) where the scaffolding will be erected (not too zoomed in)
    • Installation area for battery and/or inverter (ensure it's uncluttered)
  • Electricity Supply: Indicate if you have 1 phase or 3 phase supply
  • Cable Routing Preference: Internal or external
  • WiFi Signal: Ensure strong WiFi signal where the inverter will be installed
How do I submit the technical form successfully?
 
Clear and detailed photos are essential for the success of your submission. Please make sure your photos are:
  • Unobstructed and clearly show the necessary details (cables, text, space around installations)
  • Taken in good lighting, either with natural light or bright artificial lighting to avoid shadows
  • Taken from a distance where the installer can assess the area effectively, without being too zoomed in
Make sure to submit the form promptly, as we cannot move forward with your project until we receive this. If your form is delayed, it could impact the overall timeline of your installation. Completing this form as soon as possible is key to avoiding unnecessary delays.

DNO

DNO applications are a key step in your installation journey, we process your applications and commissioning for you so you don't have to. Here are some common questions regarding the DNO forms and their timelines.
What is a solar DNO application?
 
DNO stands for Distribution Network Operator. A solar DNO application is where a form is submitted to your District Network Operator to notify them that you’re having solar panels installed. A DNO is required for any solar installation. When you choose Soly for your solar installation, our in-house team will manage your application on your behalf.
How long does a DNO application take?
 
The DNO application process varies based on your system’s specifications and the requirements of your local Distribution Network Operator (DNO).  We will keep you informed throughout and let you know as soon as we receive approval.

The type of application depends on your system’s technical specifications:
  • G98: For systems under 3.68kW per phase, there is no pre-application needed, and we notify the grid after installation.
  • G99 Fast Track: If your system meets the fast track criteria, approval can be as quick as 14 days. These are systems between 3.68kW and 7.36kW per phase.
  • G99 Standard: For systems that exceed 7.36kW per phase, approval typically takes between 28-60 days.
How do I find out which DNO application I qualify for?
 
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.
What is the difference between DNO application and DNO commissioning?
 
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.

Installation day

Here are the answers to frequently asked questions regarding installation day.
When will my installers arrive?
 
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.
When will my scaffolders arrive?
 
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.
Are the installers certified?
 
Yes, we partner only with reputable and certified installers who meet the highest standards of quality, safety, and customer satisfaction. Our installers have extensive experience in solar panel installations and adhere to industry best practices to ensure reliable performance and long-term satisfaction.
What will happen on installation day?
 
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 happens if there’s damage to my property?
 
Our installers try their utmost to prevent any damage to the property. However, on the rare occasion there is any, they will schedule a remedial visit to repair or replace any damages. If they miss any damage they have incurred on installation day then it is crucial that you get in contact with us right away and we can liaise with your installer to repair the damages.

Documentation

Here are some answers to the frequently asked questions regarding forms and handover packs.
What is my handover pack and when will I get it?
 
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.  
How do I find my MPAN?
 
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:
  1. 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.
  2. 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.
  3. 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.
