Winfield Solar is a solar power plant in Missouri with a nameplate capacity of 150 MW.
The 150 MW is nameplate capacity: the most this plant's generators are rated to produce, not what it actually generates. EPA eGRID reports no positive net generation for it this year.
How it works
Why the numbers look like this: panels make nothing at night and less in winter, so even a well-placed U.S. solar farm averages around a quarter of its nameplate over a year. Watch the monthly bars: they swell in summer and shrink in December.

Utility-scale solar farms convert sunlight directly into electricity using photovoltaic panels. They produce zero direct emissions and have no fuel cost, but generation is variable — peaking at midday and falling to zero at night. Capacity factors typically run 18–28% in good locations.
