Cheapest Time for Electricity with Solar
Independently written
When is electricity cheapest with solar?
With solar panels, your cheapest electricity is: FREE during daylight hours (solar self-consumption), 7.5p/kWh overnight (Octopus Go tariff), and 10p/kWh overnight (Octopus Flux). The most EXPENSIVE time is 4-7pm on Flux (36p import) — avoid grid import during this window by using your battery. The optimal strategy: run everything during solar hours, charge battery + EV overnight at cheap rates, and never import during peak.
