# Create Module from Datasheet

> Step-by-step workflow for creating a module specification from manufacturer datasheet values

This workflow guides you through creating a new module specification using values from a manufacturer datasheet. PlantPredict automatically generates the [Single Diode Model](/models/dc-performance/5_parameter_model) parameters from the basic electrical characteristics you provide.

## Overview

The **Enter Basic Data** option is the fastest way to create a module when you have a standard manufacturer datasheet with STC ratings and temperature coefficients.

**Prerequisites:** Manufacturer datasheet with STC ratings and temperature coefficients

***

## Required Datasheet Values

Before starting, locate the following values on your module datasheet:

| Parameter                       | Typical Location on Datasheet     |
| ------------------------------- | --------------------------------- |
| Cell technology and cell count  | Physical specifications section   |
| Maximum Power (Pmax)            | Electrical characteristics at STC |
| Open Circuit Voltage (Voc)      | Electrical characteristics at STC |
| Short Circuit Current (Isc)     | Electrical characteristics at STC |
| Voltage at Max Power (Vmp)      | Electrical characteristics at STC |
| Current at Max Power (Imp)      | Electrical characteristics at STC |
| Temperature coefficient of Pmax | Temperature characteristics       |
| Temperature coefficient of Voc  | Temperature characteristics       |
| Temperature coefficient of Isc  | Temperature characteristics       |

## Workflow

<Steps>
  <Step title="Navigate to the Module Library">
    Click **Modules** in the [Sidebar Navigation](/user-guide/ui/ui-overview) to open the [Module Library](/user-guide/ui/module-library).
  </Step>

  <Step title="Open the Add New Module Dialog">
    Click **Add New Module** at the top of the Module Library. See [Add New Module](/user-guide/ui/add-new-module) for details on all available options.
  </Step>

  <Step title="Select Enter Basic Data">
    Click **Enter Basic Data** to open the module generator form.
  </Step>

  <Step title="Enter General Characteristics">
    Select the appropriate values for:

    * **Cell Technology** — Match the technology type on the datasheet (e.g., n-type mono c-Si, p-type mono c-Si PERC)
    * **Number of Cells in Series** — Enter the cell count from the datasheet
    * **Model Type** — Use **1-Diode** for crystalline silicon; use **1-Diode Recombination** for CdTe (see [Single Diode Model](/models/dc-performance/5_parameter_model))
  </Step>

  <Step title="Enter Electrical Data at STC">
    Enter the following values from the datasheet's STC electrical characteristics:

    * **Maximum Power** (Pmax in W)
    * **Open Circuit Voltage** (Voc in V)
    * **Short Circuit Current** (Isc in A)
    * **Voltage at Max Power** (Vmp in V)
    * **Current at Max Power** (Imp in A)

    <Note>
      As you enter values, the I-V curve preview updates in real-time. Verify the curve shape appears reasonable before proceeding.
    </Note>
  </Step>

  <Step title="Enter Temperature Coefficients">
    Enter the temperature coefficients from the datasheet:

    * **Power Temperature Coefficient** (%/°C) — typically negative
    * **Voc Temperature Coefficient** (%/°C) — typically negative
    * **Isc Temperature Coefficient** (%/°C) — typically positive

    See [Temperature Coefficients](/models/dc-performance/parameter_translation) for details on how these affect module performance.
  </Step>

  <Step title="(Optional) Fine-Tune Advanced Parameters">
    Click **Show Advanced Fine Tuning Options** to adjust:

    * **1-Diode Parameters** — Series resistance, shunt resistance, recombination parameters
    * **Effective Irradiance Response (EIR)** — Low-light performance tuning

    Use **Optimize to match EIR** if you have manufacturer-provided efficiency data at multiple irradiance levels.
  </Step>

  <Step title="Generate the Module">
    Click **Generate Module** to create the module file with calculated single diode parameters. The [Module File](/user-guide/ui/module-file) editor opens for final review.
  </Step>

  <Step title="Review and Complete Module Details">
    In the Module File editor:

    * Add **Name**, **Manufacturer**, and **Model** information
    * Review generated parameters across all tabs
    * Enter any additional data (physical dimensions, bifaciality, spectral response) if available
  </Step>

  <Step title="Save the Module">
    Click **Save Module** to save to your [Module Library](/user-guide/ui/module-library) with **Draft Private** status. After validation, consider changing the status to **Active** to make it available to your organization.
  </Step>
