In the event that your planetary system goes beyond 3.68 kWp, the single option to prevent needing a DNO application is if you intend to have your solar power entirely independent from the nationwide electricity grid. This involves linking it exclusively to your home without any connection to the UK's electrical energy system. Nevertheless, it is uncommon for people to select this choice because of the substantial costs entailed, in addition to the lack of electrical energy supply throughout wintertime.

'Relate to link' is for larger setups surpassing 3.68 kWp and requires a G99 application. This is because the DNO will certainly require to check whether the grid is able to take the additional electrical power lots before your system is up and running.
