This document discusses analyzing and presenting big data from renewable energy systems. It includes charts showing average temperature over time and produced kilowatt hours over time from solar tracking systems. Key performance indicators measure kilowatt hours over time to evaluate progress toward the objective of meeting power needs through increasing the number of Yingli solar tracking systems over five years. Analysis indicates Yingli trackers are most valuable and open systems are most reliable, and correct interpretation of data through analysis can lead to valuable results.
