About Solar plants

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.
