Swindon visits are grouped with Salisbury and Bath. Most of its housing is late-twentieth-century estates with simple roofs and drives: Toothill, Freshbrook, Abbey Meads, Haydon Wick and the newer Wichelstowe. Old Town and the Railway Village are older, with a conservation area around the latter. The estates have a high share of commuter households out in the day, which is exactly the pattern a battery is designed for.
The logistics and business parks along the M4 corridor are large daytime loads with enormous flat roofs, where commercial solar pays back fastest.
