Solar panels, batteries, and charging in a Cornwall counterfactual

A counterfactual about Cornwall connects earlier household solar support with later batteries, chargers, and electric-car adoption. The proposed sequence concerns personal cars, with goods vehicles treated separately. A second participant describes a friend's experience of needing more battery capacity after installing solar panels. The journey anecdote includes an initial claim about travelling on one charge followed by the clarification that the car was topped up in Cornwall. Together, the contributions illustrate their argument about the supporting household infrastructure, without supplying a verified range comparison or a full account of the earlier grant scheme.
