Getting set up for solar power generation

On a sunny day, solar power generation systems connected to our network produce enough electricity to run more than 800 average sized houses.

It’s important for us to know when new solar generation systems (known as photovoltaic or PV systems) are planned for connection to the network because we need to make sure the equipment meets required technical standards and is set correctly to maintain a good level of power quality for everyone using the network. We also need to know where PV systems are so we can keep line workers safe when they undertake network maintenance.

Our process to help guide you through getting a PV system connected to the network is as follows:

Stage 1:  Before you purchase a system, check our website to understand how the application process works and what sort of things you need to think about, such as whether you want to connect to the network, whether the system meets the required technical standards, and the size of the system.

Stage 2:  If you decide you want to connect the system to the network, fill in a pre-purchase application form.  This form is on our website at We use the information provided on this form to check that part of the network you want to connect to has the capacity to handle the power from your system and to make sure it meets the required technical standards. We will also pass the details on to your energy retailer.  They will make arrangements to fit a new meter that can record any surplus electricity exported back into the network.

Stage 3:  Once your system is installed and before it is connected to the network by a Network Tasman approved contractor, the installation will need a Certificate of Compliance issued, import/export metering fitted, and a final inspection.  Your installer or electrician will help with arranging these things.
