@christineburns If you have access to hourly kWh data from your solar and your house, you might be interested in reproducing this spreadsheet. It will tease out a truer picture of the seasonal variations. I can help.

@icanbob Thanks for the offer but I’ve already got my spreadsheets set up. I know full well that the system won’t receive anything like enough solar input during the first and last 10 weeks or so in the year but that isn’t my aim. I’ve been collecting daily demand and COP data since the heat pump was installed and the calculation is to use this time of use smart tariff to recharge the battery in the three half price tariff slots each day so as to run throughout on low..
