I took down a Solarcan (no. 4959/5000) the other day and scanned it today. This is a square crop of the result of a sixteen month exposure. The white lines that you can see are the path of the sun of 16 months. The bottom of the image is the tree line. The photo below was edited in Lightroom, the original image is also included, so you can see what it looked like when I had scanned the image and initially inverted the colours. These cameras are incredibly easy to use and I have three more Solarcans to install, and I’m looking forward to seeing the results of those cans too. I have added a link to Solarcan below.
Straight out of the scanner. 
Edited.
