In the beginning of the year we consumed more electricity than we produced. There were two drivers of this. One, fewer daytime hours means less electricity produced by the PV panels on the roof. And two, colder outdoor temperatures means that we need to consume more electricity running the heat pumps. You can see in the chart above that this trend was reversed in March as evidenced by the orange "Net" line in the chart above starting to slope upwards.
In April, May and June we produced significantly more electricity than we consumed. We see the same two drivers at work again. One, more daylight hours means more electricity produced by the PV panels on the roof and two, warmer outdoor temperatures means we consume less electricity because we need to run the heat pumps less frequently.
It'll also be interesting to see how our PV panels perform the rest of the year. So far they are performing very close to the estimates we received from the company we bought them from, Aegis Solar. You can see from the chart below that we produced more electricity in April than in June. This probably has something to do with the 34 degree angle to the horizon of the panels on our roof being better suited to the sun being somewhat lower in the sky.
