NightOwlSolar panels to be fitted on all new-build homes in England by 2027
symbolicWhile solar power is great and possibly the future, I sure hope they fully thought this through. A lot of areas with large numbers of solar panels are struggling to manage overcapacity. Solar energy produced is not always sent to the grid but wasted, as there is often not enough grid-scale storage capacity to absorb it. I’m no expert, but I wonder if mandating smart in-home sodium-ion batteries which intelligently charge and discharge based on grid capacity wouldn’t be more effective.
Sunlight hitting a roof without solar panels is also often not sent to the grid but wasted. In fact, I’d say that more solar energy is wasted on roofs without solar panels than with.
People who install solar on their roofs usually expect to recoup some of the costs by sending energy to the grid. When, increasingly often, they have a choice of either shutting the system off and wasting this energy or sending it to the grid at low or even negative rates, this becomes a problem. The expectation of “my solar system will pay for itself in X years” might become “my solar system will never break even”. At least that’s an issue in some places with high PV density.

Not under this law. This whole article is about solar panels being mandated by law, regardless of whether or not the installer thinks they can profit from them. Keep moving those goalposts, though.
I’m just pointing out an issue with residential PV which, when I first heard about it, surprised me. I hope it does not surprise the people making these laws.
Imagine if, some years from now, seasonal solar oversupply might become in the UK and the people with these by law mandated panels face the choice to either manually switch off their system or pay to send their solar energy into the grid. It sounds stupid but this seems to be happening in places with high PV density.
Goalposts go wheeeee!!!
You’re allowed to use the solar on the roof before buying from the grid which will save you tons on most days. The UK grid operates on marginal pricing so if you buy from the grid the highest price provider dictates the price.
This essentially means that you pay the peaker plant nat gas price for electricity where every MWh hits pretty hard on the bill. To recoup the investment in the UK, especially with the interconnectors inside the Eurostar tunnel, is pretty easy and a decentralised grid allows the UK to skip building a lot of power lines for energy that’s used locally.
