-The rover is powered by a battery. The battery is charged by three solar panels: one on the left, one on the right and on at the back of the rover. The panels are tilted sideways to face the sun which is low on the horizon when close to the moon south pole. Total power of the solar panel is 450W [[source]](https://science.nasa.gov/mission/viper/in-depth/) and therefor each panel was estimated to produce 150W at full capacity (sun hitting horizontally). The solar panels are simulated using a specifically developed plugin, detailed later in the document.
+The rover is powered by a battery. The battery capacity is estimated to be around 28,800Wh(960 Ah) assuming 300 w average consumption over 96 hours, the intended timeline of the mission.

 #### Sensor suit <a name="sensor_suit"></a>
 It features a similar sensor suit of the real VIPER rover. Detailed characteristics were obtained from [359199649_VIPER_Visible_Imaging_System](https://www.researchgate.net/publication/359199649_VIPER_Visible_Imaging_System) and [20210015009 - Colaprete-VIPER PIP final.pdf](https://ntrs.nasa.gov/api/citations/20210015009/downloads/20210015009%20-%20Colaprete-VIPER%20PIP%20final.pdf) and [viper-moon-rover-head-neck-mast-installed](https://www.space.com/viper-moon-rover-head-neck-mast-installed).
