Solar Panel Wattage

Solar panel wattage represents a solar panel's theoretical power production under ideal sunlight and temperature conditions.

The amount of electricity a solar panel produces depends on three important factors:

  • Size of the panel.
  • Efficiency of the solar cells inside.
  • Amount of sunlight the panel gets.

For Example:

A 20 Watt Solar Street Light has a battery capacity of 60 AH and 3.2 Volts, that is 190 Watt Hours. Normal sunlight should be sufficient to charge the battery as it needs to generate 3.2 volts power.
