A Simple Guide for Solar Installers
If you’re working in the solar industry, you’ve probably heard about G98 and G99 applications. But what exactly is a G98 DNO application, and when do you need one? Let’s break it down.
Understanding G98: The Basics
A G98 application is the process used to notify your local Distribution Network Operator (DNO) about a small-scale solar PV installation—specifically systems up to 3.68kW (or 16A per phase). This process is sometimes called “Notification to Connect.”
Why notify the DNO? Because any solar system that connects to the electricity network needs to be registered for safety, compliance, and to ensure the network can handle the extra generation.
When Do You Need a G98 Application?
- Residential solar PV systems
- Small commercial installs under 3.68kW
- Systems with up to two inverters (usually small single-phase installations)
If your system is larger or more complex, you’ll likely need a G99 application instead, which involves a more detailed and rigorous approval process.
What’s Involved in the G98 Application?
Submitting a G98 application involves providing the DNO with key details about your installation, such as:
- Inverter manufacturer and model
- Panel manufacturer, size, and quantity
- Installation address and customer contact information
- A schematic diagram of the system
Once submitted, the DNO reviews the application and issues an approval letter. This letter confirms the system can safely connect to the network.
Why Is G98 Important?
- Ensures compliance: Keeps your installation legal and safe.
- Protects the grid: Helps the DNO manage network stability and safety.
- Speeds up installs: Proper notification avoids future issues and penalties.
