Air Conditioning + Solar in Cambridge
The original SunCooled bundle. A correctly-sized solar array produces its peak output exactly when your AC demand peaks: hot, sunny days. Bundle them and the electricity that runs your cooling is effectively free. In Cambridge, where summer highs regularly reach 28°C, the case for cooling is clear, and the same sun driving that heat can power it.

Built for 28°C summers
Cambridge homes, many built to retain heat, now face sustained summer peaks. A correctly-sized 1 to 2 wall splits makes the difference between an unusable room and a comfortable one.
Solar in Cambridge
The East sun is enough
A 3 to 4 kWp solar array in Cambridge generates plenty on the hot days you need it most, covering daytime cooling load with surplus to spare.
Questions, answered
Can solar panels really run an air conditioner?
Yes. A modern inverter split AC draws roughly 0.8 to 1.5 kW while a 3 kWp solar array can produce 2 to 2.5 kW on a sunny summer afternoon, comfortably covering the load while the sun is up. That is exactly when you want cooling.
What does the bundle cost?
A 1 to 2 unit wall-split AC install plus a 3 to 4 kWp solar system typically starts around £5,900 before any grant. Grants can remove £1,500 to £7,500 from that figure depending on eligibility.
Do I need a battery?
Not to make cooling work during the day. A battery lets you shift spare solar into the evening, but for daytime summer cooling the panels alone cover most of the running cost.
