Solar Panel Voltage Calculator Formula

The required voltage for your solar panel system is calculated using the following formula:

Required Voltage = Ceil[1000 / (Panel Area * 15)]

This formula takes into account the power consumption, operating hours, system efficiency, autonomy days, battery voltage, solar panel efficiency, and solar panel temperature. It calculates the panel area and uses it to determine the required voltage for the system.

Illustrative Example

Let's consider an example to illustrate the use of the "Solar Panel Voltage Calculator." Suppose we have the following parameters for a solar panel system:

  • Power Consumption: 1500 Watts
  • Daily Operating Hours: 6 hours
  • System Efficiency: 90%
  • Autonomy Days: 2 days
  • Battery Voltage: 24V
  • Solar Panel Efficiency: 18%
  • Solar Panel Temperature: 35°C

By inputting these values into the calculator, we can determine the required voltage for the system. After performing the calculation, we find that the required voltage is approximately 51.8V.
