Understanding Solar Panel Efficiency

Solar panel efficiency is a measure of how effectively a solar panel converts sunlight into electricity. It is expressed as a percentage and represents the ratio of the electrical power output to the total solar energy received by the panel.

A higher efficiency means that the solar panel can generate more electricity from the same amount of sunlight, making it more effective and cost-efficient.

Factors Affecting Solar Panel Efficiency

  • Solar Irradiance: The amount of sunlight reaching the panel. Higher irradiance generally results in higher efficiency.
  • Temperature: Solar panels typically become less efficient as temperature increases.
  • Panel Quality: Higher quality panels generally have higher efficiency.
  • Angle and Orientation: The angle and orientation of the panel relative to the sun can affect its efficiency.
