Solar and Energy Storage System Configurations: Central TX

Each of the year-one case studies described in Scenarian’s articles are built on models including a solar array, an energy consumption profile, and an energy storage model (when applicable). All models that are linked to this page will share a common energy consumption model1

The model parameters described below apply to the following year-one case studies:

  1. Energy consumption and solar production models involve location and weather information. The pricing plans discussed may not necessarily be available in the area specified; they are used to illustrate concepts, not to advertise a particular energy policy. The energy production and consumption models should not be used to concretely predict the outcome of your own solar energy project. ↩︎

  3. The simple battery model treats the battery as a single energy reservoir with a fixed nominal voltage. It computes the energy transferred as

    Energy=Voltage x Current x Time

    and relies on a single round‑trip efficiency factor to represent all losses. By assuming the battery voltage remains constant regardless of state‑of‑charge or charge/discharge rate, the model omits details that more sophisticated models address. Alternatives such as the kinetic battery model, equivalent circuit model, and electrochemical model, might be discussed by Scenarian in the future. ↩︎
