Our best solar PV generation day so far

It’s been a glorious early Spring day today with continuous sunshine from dawn til dusk, and as a result it’s also been our highest solar PV generation day since the system was installed just over a month ago. You can see this from the chart produced by my automated data gathering and chart generation tool running on my Linux server:

As you can see we generated a total of 20.81 kWh of electricity throughout the day, peaking at an output of 3.17 kW at around 1:30pm. With the feed-in tariff (FiT) rate now confirmed as 43.3p/kWh for our installation and a deemed export rate of 50% of generation at 3.1p/kWh, this makes a total daily income of £9.27. That doesn’t include any savings on electricity that we were able to use ourself during that period instead of having to import it from the grid.

Although it’s still early days for our system and we are only just into Spring, things are looking promising for meeting or exceeding the estimated output for the system over the next year.
