Charts & Graphs, by Date

tracker panel 

Ameren uses four different photovoltaic technologies with our solar energy project. Choose a date and view all four historical generation technologies simultaneously.

Each colored line represents one of the four technologies (monocrystalline, polycrystalline, thin film, or monocrystalline mounted on trackers) that Ameren has installed.

Because the installed capacity of each technology is different, we employ a “normalization” factor that adjusts each technology type to a common capacity that allows a valid comparison of efficiencies and output by type. Read more about our normalization formula.

If the generation output stays at the exact same level for a significant part of the day, this may indicate a "quality of data" issue.

  • Kilowatt (kW)
    A unit of measure used to express the output power of a solar array.
  • Kilowatthour (kWh)
    A unit of energy equivalent to one kilowatt of power expended for one hour of time. A measure of energy consumption.
