DNO applications

[Alan Ambrose]

I’m tempted to use Spirit Energy’s £150 DNO application. We are going ‘max-PV’ to try and get self-sufficient power into the shoulder seasons. Is there a sense that you need to tread lightly with the DNO and finesse your application to get closest to what you want - or just go for it and see what they say? Our DNO is UKPN, we have single phase supply, and we want oodles of panels to support shoulder seasons use. House is PH-like but not particularly low energy because of the geometry.

We're only just into G99 but my impression from our installer was that the DNO set an export limit rather than just saying no.

I’ve heard that some DNOs also want to restrict the size of your array / inverter output etc.

Are you having a battery also, if so you need a strategy of what you are doing, as big is better to a point. You maybe better over clocking the inverter with loads of panels, so you have max output for longer periods during a day, and get battery charging as well as max exports.  Lots of ways to do this even with a G98 limitation.
