The ESB requires you to submit an NC6 Form to register your solar panels and have them connected to the utilities grid.
Without this, you won’t be able to connect to the electrical grid, which will make a solar PV system more expensive to set up. You also won’t be able to receive payment for the electricity you export through the Clean Export Guarantee.
The ESB requires the form to ensure that they have all the details of your solar PV system, including its power output, to better manage and safeguard the electricity grid. It also proves that your system is up to scratch, and installed by a qualified contractor.
If you don’t complete this, it won’t stop you from having solar panels installed, but you won’t be able to connect them to the grid.
This can become a more expensive option, as off-grid solar systems require extras such as a battery, potentially adding thousands to the cost. There will also be added maintenance issues and costs, as solar storage batteries do not last nearly as long as solar panels.
