Not much to learn really except:
- The new system being lower down, closer to the houses behind, and almost horizontal, doesn't pick up much winter sun.
- The new system actually does better than the original one kWh/kWp on bright overcast days. But lots of the overcast days haven't been bright or long enough for this to add up to much usable power.
- Putting together the data for 2 systems is 4x more complicated compared with one system!
