A project log for SOL: Long-term solar intensity sensing

SOL is a project to develop a solar powered, connected solar intensity sensor (also known as a pyranometer)

I did some further analysis on the data recorded by SOL over the past few days. Of note were the peaks in recorded power in the afternoon of the 7th and 8th, which did not appear the next days. I correlated the data with historical weather data on shortwave light intensity and cloud cover. During the days with the peaks in power, the cloud cover cleared up somewhat, and the peak predicted intensity was relatively high. As noted before, SOL was not in direct sunlight for these tests, so the absolute value isn't important here, but it is encouraging that it seems likely that those higher power sections were due to real phenomena.
