December Solar Generation and Export Numbers
Here is the overview for December 2023.
The worst generation day was the 27th with only 0.20 kWh. The best was the 6th when 3.90 kWh was generated.
The best export day was the 24th with 2.90 kWh. This was not a solar export, but a force battery discharge. It was an Octopus Energy Savings Session. There was six Saving Sessions in December. We earnt 15,784 Octopoints. Each point is worth 8p. This meant we earnt £19.73 over those six sessions.
Rather than show an export profit, I thought it would be easier to show the cheapest day. December also had some excellent Octopus Agile plunge pricing slots. These are slots where we are paid to use electricity. From the 21st to the 26th our electricity cost less than 50p

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 28.10p 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. Forty four of those slots were plunge pricing slots. This compares to only six in November. These are where we get paid to use electricity.
