The amount of energy that can be harvested changes every day. This timelapse movie shows the daily potential between April 25th 2015 and April 24th 2016 (365 days).

To create this movie, I have written a python script that loops through the period of time that I target. during each iteration, I ask rrdtool graph to create a png file containing the solar potential data relative to the current day. This script was executed by the Raspberry Pi hosting the rrdtools data base and the website.

Once the 365 png files created I transfered them into Movie Maker on my Windows PC and I created the timelapse movie in a few minutes.
