What is cheaper for a company of 500 people?
1) A foolproof RAID + backup system, + expenditure in dealing with replacements, loss and transfer of backups
2) stacks of paper
A company of 500 people already has an IT infrastructure. It's mostly a problem of culture adaptation mixed with the fact that most software replacements are complex and expensive tools.
This experiment may be a case of having optimized for the capture of diffuse light. I think that the "natural" arrangement of solar panels would be only better if diffuse light was dominant over direct light. Multiple commenters have noted that trees were obscuring the flat array. We can presume that the location of the experiment had a limited amount of direct light. Also, a higher proportion of diffuse light during the morning and evening could explain the longer time periods of energy production.
If this hypothesis is revealed to be true, that could mean that this "natural" arrangement of solar panels may be optimal in situations where there is only indirect light available, such as interiors. Otherwise, I stay confident that the current knowledge about the placement of solar panel still holds.
