A year of solar data
Our solar array has been up and running for a year now. Since we have micro-inverters from Enphase , I'm able to log data every 5 minutes on how much solar power we're producing (you can browse a summary view of this data at Enphase's public page for our system ). I've saved this data over the entire year (over 70,000 data points). Here are a few visualizations of the data. First, a simple contour map of the raw data - blue is 0-2000 watts, red is 2000-4000 watts, and green is more than 4000 watts of instantaneous power being produced by the array: This is the same data, but smoothed with a 5x5 box filter and viewed in perspective - it lets you see the longer weather events we've had (multi-day winter storms, extended summer cloudy intervals) - it gives the data an interesting "array of stacks" view: And here is a chart showing the average-per-time-of-day and maximum-per-time-of-day power production (note that in all these charts time-of-day has ...
