January Solar Generation and Export Numbers
Here is the overview for January 2024. January was not a bad month. We generated almost twice as much as we did in December. There were two days with plunge pricing and one Saving Session. We had some very cold nights which affected the battery charging. In fact, one night the battery only charged to 80% and need an extra slot to get to 100%. I will write about this in a separate post.
The worst generation day was the 2nd with only 0.60 kWh. The best was the 26th when 6.90 kWh was generated.
The best export day was the 17th with 2.50 kWh. This was not a solar export, but a force battery discharge. It was an Octopus Energy Savings Session. I will post more about this when the program ends. I can say at this point, it has been worthwhile so far. We have made over £30 from the sessions. This session was worth £5.07.
Rather than show an export profit, I thought it would be easier to show the cheapest day.

Octopus Agile
The costs shown here do include the standing charge. Any comparisons are compared to the unit cost if we were not on Octopus Agile, which is 29.22p per kWh. This is the new unit cost after the price cap took affect. The standing charge is 0.3730p
As you can see once again we used more Agile slots to charge the battery overnight. Six of those slots were plunge pricing slots. These are where we get paid to use electricity.
