AC + Solar + Battery in Southampton
The full package. Solar by day, a battery that stores the surplus to run your AC into the evening, and enough panel capacity to cover daytime cooling with headroom. The closest thing to free cooling, around the clock. In Southampton, where summer highs regularly reach 27°C, the case for cooling is clear, and the same sun driving that heat can power it.

Questions, answered
How big a battery do I need for AC?
A 5 to 10 kWh battery typically covers several hours of evening AC across 2 to 3 rooms. We size it to your summer night-time load, not just winter heating.
