August sees us here in Aotearoa (New Zealand) getting more sunshine as the days get longer again. Also, we went away to Europe in the last week of the month. How did we do?

Findings
As the days get longer, we are exporting more and more solar energy to the grid for a credit. This, combined with us using less electricity for the month (because we were away for almost half the month) resulted in a very small bill.
