Most commercial solar projects don’t start with panels.
They start with the DNO.
The DNO (Distribution Network Operator) is the organisation responsible for the local electricity network infrastructure in your area. Before a commercial solar system can be installed, the DNO assesses how much generation the grid can safely handle at your site.
It’s one of the most important parts of the process, because it can influence:
• System size
• Export capacity
• Battery strategy
• Project timelines
• Overall project economics
In this video, our Head Electrician Mark R***r breaks down what the DNO actually is, why it matters, and how understanding it early can help commercial projects move more smoothly from design through to installation.
