Energy yield

Meaning in energy & renewables, with examples

nounCommon term

In energy & renewables, energy yield means: The amount of electricity a solar or wind plant produces, or is expected to produce, over a period, usually a year. It is the basis of revenue forecasts.

In Turkish: enerji üretimi, yıllık üretim, özgül verim

How it is used

Common in project finance and technical due diligence. An energy yield assessment estimates annual output; banks look at P50 and P90 values, the output expected to be exceeded with 50 and 90 percent probability. Specific yield is the yield per kWp.

Example sentences

  1. The energy yield assessment predicts 1,650 kWh per kWp in the first year.

  2. Actual energy yield was 4 percent below the P50 estimate because of a cloudy spring.

Common collocations

  • energy yield assessment
  • annual energy yield
  • specific yield
  • P50 and P90 yield
  • capacity factorThe ratio of the electricity a plant actually produces over a period to what it would produce running at full capacity the whole time, shown as a percentage.
  • irradianceThe power of sunlight falling on a surface at a given moment, measured in watts per square metre (W/m²). It sets how much a solar panel can produce at that time.
  • kilowatt peakThe power output of a solar system under standard test conditions, used to state the size of a PV installation. It is written kWp; larger plants use MWp.
  • solar farmA large ground-mounted installation of solar panels, usually covering many hectares, that produces electricity to sell to the grid rather than to power a single building.
  • wind farmA group of wind turbines built in the same area and connected together, feeding their electricity into the grid through a shared substation.
