Britain responds to Iran war energy shock by requiring solar panels and heat pumps in all new homes - feddit.org

> The U.K. government on Tuesday introduced new rules requiring developers to install heat pumps and solar panels in all new homes across England, in policymakers’ latest response to the economic fallout of the Iran conflict. > > U.K. ministers say the Iran war and the largest supply disruption in the history of the oil market reinforces the need to leverage clean power as an energy security tool. > > The Future Homes Standard — a set of new-build regulations for England from 2028 — will establish requirements to ensure homes are built with on-site renewable electricity generation, the majority of which is expected to be provided by solar power. > > > The rules will also see homes built with low-carbon heating, such as heat pumps and heat networks. > > The government added that plug-in solar panels, which homeowners can install on balconies, would be available within shops over the coming months.

Seems wasteful not to cover one whole roof with panels (possibly replacing the sheet metal entirely) and connect them to one big inverter to power four homes. Splitting the needed amount of panels and inverters for every house wastes lots of installation work and makes every roof uglier. Seems wasteful to require solar panels on homes shaded by trees or aligned the wrong way.
So, whose roof is going to get drilled all over the place risking leaks in the future? Yours? Also, the increase in installation costs is less, as you wouldn’t have to lay lines linking the houses, making and closing trenches, etc. one big inverter is a single point of failure. Again, in your house, or build a shed to house it?

Everyone’s roof is getting drilled, says the new requirement - I’m suggesting reducing the drilling. Of course the three without installations would compensate the one carrying everything for them.

All houses are linked by the electrical grid already, no new threnches needed.
