Electrical generation capacity is measured in watts, or thousands of watts (kilo-watts, or "kW") and indicates the total power output at any given moment. (Similar to a car speedometer, which shows the rate of speed at any given moment.)
Electrical production is measured over time, in kilowatt-hours ("kWh"). (Similar to a car odometer, which shows cumulative progress over time.)
When solar generation is greater than facility demand, excess power is exported to the utility grid. Alternatively, if facility demand is greater than solar production, power is imported from the utility grid as it would be normally.

Positioning your cursor over points on the graph will indicate power produced (kWh) for the chosen time period.
According to the United Nations Intergovernmental Panel on Climate Change "Fourth Assessment Report" published in November 2007, the planet is undoubtedly warming, there is "very high confidence" that warming is due to marked increases in man-made greenhouse gas emissions, and carbon dioxide is the most important greenhouse gas.
By generating its own power, this facility has dramatically reduced its electricity purchases of power from the local utility. As a result of the reduced demand, there's a corresponding reduction in nearby power plant emissions and pollution.
Solar production begins at sunrise, peaks at solar noon, and declines through the afternoon until sunset. Power generation correlates with solar irradiance*, which means haze, fog, clouds, inclement weather, shade, and module soiling impact production.
This solar power system was designed for this site, with the goal of maximizing production given variability in local conditions and site features.
* Irradiance is the amount of solar radiation failing on a given surface area at any given moment, measured in watts-per-square-meter (w/m2).
