Octopus Cosy and Solar

Is Octopus Cosy good with solar?

Octopus Cosy is designed for heat pump owners: CHEAP PERIODS: discounted rates during typical heat pump running hours (morning warm-up, evening). PEAK AVOIDANCE: higher rates during 4-7pm peak (when grid demand is highest). WITH SOLAR: (1) Solar covers heat pump electricity during daylight hours (free). (2) Cosy cheap rates cover morning and evening heat pump use (discounted). (3) Battery stores solar for peak hours (avoids expensive 4-7pm rates). RESULT: the cheapest possible heating combination — free from solar during the day, discounted from Cosy morning/evening, peak avoided by battery. Annual heating cost: potentially £100-£250 (vs £800-£1,200 on gas).
