Solargraphy: What Went Wrong?

So I had to take down my rooftop SolarCan, because we are getting a new roof installed. 

Here, the installation photos from March 2018.

But this was the result?

It seems to have failed badly, in the past I've had so-so results.

So I have 3 still deployed and one left to put outside.  

I don't think we'll go on the rooftop again.
