"Read the specification and the boundary is unmistakable. The first legal wave is panels and a microinverter. No storage. A kit that includes a battery, or an inverter with a battery bolted to it, falls outside the specification and cannot claim compliance."
"The pattern is clear. Buy generation on its own and you are inside the rules from 27 August. Buy anything that stores what those panels make, and you are waiting for the next round."
"Our best reading is a legal route for battery-integrated plug-in solar around early 2027, assuming DESNZ starts the battery safety study promptly once solar goes live this August."
So storage is only out until the rules are set for it - by their reading of the tea leaves it's coming about 6 months later.
