Surely the question is what the local energy distribution network is going to do with the midday surge in generation for which there is no local demand. Any sort of big development and there will be a huge local supply and demand imbalance.

The grid voltage will rise and domestic inverters will progressively shut down until it falls again.

Does that happen now?

Yes, when necessary.

Solar panels to be fitted on all new-build homes in England by 2027

Almost all new homes in England will be fitted with solar panels during construction within two years, the government will announce after Keir Starmer rejected Tony Blair’s criticism of net zero policies.

Housebuilders will be legally required to install solar panels on the roofs of new properties by 2027 under the plans.

The policy is estimated to add between £3,000 and £4,000 to building a home but homeowners would save more than £1,000 on their annual energy bills, according to the Times.

If the panels matches some of the new house building quality might be hard pushed to power a light.

Surely the question is what the local energy distribution network is going to do with the midday surge in generation for which there is no local demand. Any sort of big development and there will be a huge local supply and demand imbalance.

As well as inverters powering down / "slowing down" as required...

The energy can flow back into the wider grid. 

So even if it wasn't required this side of your local substation, hopefully other areas which may include businesses can make use of the excess. 

Tim and Kat (YouTube) covered this recently, lots of detail in the comments.

My understanding was that most local stepdown transformers only worked in the supply direction - my parent shave only 4kwp of panels but their DNO will not allow them to have any more as a few other houses locally also have solar.

The DNO cannot stop them having more panels, they can cap their export rate. If they want more panels and would be able to use the energy themselves then it can be a good investment, especially with a battery that allows them to export at times when their generation would not max the export normally.

Private sector is unreliable. Are they playing for a bigger subsidy? Or serious and project is canned.

From the article

"The government has said it plans to work with Orsted to get Hornsea 4 "back on track" and said it believed the clean power mission was still achievable"

FOS wind saw initial proposal for CfD cap to near double at one stage for the last auction round after the previous round sold no FOS wind - but did sell more on shore and solar - but I think the auction price came in about 60-70% higher in the end.  But some articles were confusing 2012 rates - how normally quoted - and indexed current.

I suspect they will be haggling for that increase to get closer to latest projects - or a decent chunk of it.

An issue is the race to 95% by 2030. Putting a time-frame on it like going to a car dealer and  stating how urgent is to buy a car from them then asking for their best deal!
