## Overview

This packaged 0.45 W solar cell has a 5.5 mm × 2.1 mm barrel plug termination. It is a custom solar cell produced for SparkFun – not a small toy or surplus cell. This solar cell is rated for 4.5 V open voltage and 100 mA short circuit. A random cell SparkFun tested outside measured 4.95 V open voltage and 94 mA short circuit.

The 2 m long cable is terminated with a 5.5 mm × 2.1 mm center-positive barrel plug. The 3.7" × 2.4" package has a clear epoxy coating with hard-board backing, robustly sealed for outdoor applications. The cell is monocrystalline and has an efficiency of approximately 15%.

**Note:** SparkFun calls this product the “Solar Cell Small – 0.45W”, SKU: PRT-07845
