The purpose of this graph is to track two things:
- How solar generation is affected by hours of daylight
- The degradation of solar performance over time
The first one is obvious given we're talking about solar power, I just wanted to see how it would look visually. The second one probably won't show a useful pattern until a couple of years down the track.
