A Solar Panel Specialist’s Guide to DNO Applications

When it comes to solar panel installations, there’s a lot to consider. One crucial aspect that often gets overlooked is the DNO application process. If you’re considering getting solar panels, understanding the regulations surrounding DNO applications is essential for a seamless installation. This short guide will tell you what you need to know.

What is a Distribution Network Operator (DNO)?

In simple terms, a Distribution Network Operator (DNO) is a company that owns and manages part of the physical infrastructure of the electrical grid, including power lines, cables and substations. There are lots of different DNOs in the UK, with the biggest being UK Power Networks which covers London, the South East, and the East of England. The one you’ll need to be aware of when getting solar panels in Exeter, though, is Western Power Distribution.

Understanding DNO Applications

A DNO application is a formal submission to your area’s DNO that notifies them of your solar panel application. There are a few different forms; the one you’ll need to submit depends on the panels being installed. In some instances, the application should be submitted before installation (‘apply to connect’), while in others it’s fine to submit them afterwards (‘connect and notify’).

Why DNO Applications Matter

Submitting these forms is necessary because they help to ensure the seamless integration of your solar panel system with the grid. When any kind of energy-generating technology is connected to the grid, it can cause voltage spikes. This could then cause issues like flickering lights or even tripping the network and cutting off supply altogether. 

DNO applications help mitigate these issues by ensuring safe and efficient energy distribution. As solar panel specialists in Exeter, the team here at Sunflower Solar Solutions prioritises compliance with DNO regulations for hassle-free installations.

Who Needs to Make a DNO Application?

The UK Government website outlines that anyone installing solar panels or any other energy device in their home is required to register it with their DNO. This step previously wasn’t necessary, so you might come across conflicting advice online - speak to one of our solar panel specialists for reliable, expert advice if you’re unsure of anything.

Steps to a Successful Application

  1. Choose Certified Solar Panel Installers – Your DNO will require that your solar panel company is either registered with a Competent Person Scheme or certified through a certification body. At Sunflower Solar Solutions, our team of solar panel installers in Exeter and beyond are fully NICEIC-certified, Part P-registered, TrustMark-accredited and MCS-certified. Not only that but we take care to adhere to the RECC (Renewable Energy Consumer Code) in everything we do.

  2. Determine the Application Type Required – Depending on your chosen solar panel system, the type of DNO application required may vary. Some systems will only require you to notify the DNO after installation, whereas others will require you to notify the DNO beforehand. Our solar panel specialists will be able to advise on which application type is needed in your specific circumstances.

  3. Install Your Solar Panels – Once your application has been received and approved by the DNO, our team will be able to go ahead with your installation. Our solar panel installation service goes above and beyond to ensure fantastic value for money and improved energy independence.
