How Trimark Boosts Efficiency of PV Plants with Precise Meteorological Data

Because of the nature of the sun and the sky, the production of a photovoltaic plant is highly variable. Though we can’t make the sun shine at the snap of our fingers, PV site operators nevertheless need to react to these fluctuations as quickly and appropriately as possible to avoid significant revenue losses—including penalties from regional ISOs.

To mitigate these effects, Trimark takes a proactive approach: we leverage precise meteorological data to allow us to compare estimated production with actual plant performance. Among the analyzed data are solar irradiance, temperature, humidity, wind speed and direction, and more.

Matt Kesselring, a data scientist here at Trimark, recently demonstrated this in a collaborative case study with Kipp & Zonen, a division of OTT HydroMet that specializes in measuring solar and atmospheric radiation. In the case study, Matt uses two different data sets from the Riverside plant in Southern California to showcase how Trimark utilizes these meteorological data to great effect.

Ultimately, this study seeks to answer two main questions:

  • How much is a site producing?
  • How much should it be producing?

The data-based methodology behind these determinations is invaluable to anyone operating a PV plant, as one should always be prepared for a rainy day—in this case, quite literally.
