The tendency of the sunlight to electricity conversion efficiency of amorphous silicon photovoltaic devices to degrade (drop) upon initial exposure to light.
Industry:Energy
The thermodynamic cycle that is an ideal standard for comparing performance of heat-engines, steam power plants, steam turbines, and heat pump systems that use a condensable vapor as the working fluid; efficiency is measured as work done divided by sensible heat supplied.
Industry:Energy
The time of the day, at a specific location, when the sun reaches its highest, apparent point in the sky; equal to true or due, geographic south.
Industry:Energy
The torque at the bottom of a speed (rpm) versus torque curve. The torque developed by the motor is a percentage of the full-load or rated torque. At this torque the speed, the rotational speed of the motor as a percentage of synchronous speed is zero. This torque is what is available to initially get the load moving and begin its acceleration.
Industry:Energy
The total amount of electric energy loss in an electric system between the generation source and points of delivery.
Industry:Energy
The total capacity of electrical generation devices in a power station or system.
Industry:Energy
The total diffuse and direct insolation on a horizontal surface, averaged over a specified period of time.
