Solar update

Today, the five-day moving average of electricity generated per day clicked over 5 kWh (and, for that matter, over 6kWh). We've had odd days when the amount generated has been up to nearly 8 kWh, but this has been the first time when the average has been consistently above the 5 unit point.

The significance of this is that, to make the money that Rayotec claimed for the system, we need to generate around 5 units per day, averaged over the whole year.

We've been monitoring energy usage closely as well, and it's interesting watching the falling trend here. This is partly due to the increase in generated electricity that we have been able to use, but also because as the days get longer and milder, less electricity is used generally.

The next interesting milestone will be when we see a day on which we generate more electricity than we use.
