Charts & Graphs, by Technology Type

solar panels 
Ameren uses four different photovoltaic technologies on our solar energy project. Choose a technology type, and the chart will refresh and display the current energy output.

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.
