Solar panel efficiency refers to the percentage of sunlight that a panel can convert into usable electricity. For example, a panel with 20% efficiency will turn 20% of the sunlight it captures into power, while the remaining 80% is lost due to heat or reflection. Higher efficiency means: How Is Efficiency Measured?
This process is constant. Over 500 million tons of hydrogen atoms are converted into helium every second, resulting in photons that generate solar energy here on Earth. In a nutshell, solar panels generate electricity when photons (those particles of sunlight we discussed before) hit solar cells. The process is called the photovoltaic effect.
The conversion efficiency of a photovoltaic (PV) cell, or solar cell, is the percentage of the solar energy shining on a PV device that is converted into usable electricity. Improving this conversion efficiency is a key goal of research and helps make PV technologies cost-competitive with conventional sources of energy.
The process of converting sunlight into usable electricity involves six key steps: When sunlight hits a solar panel, photons penetrate the anti-reflective coating and enter the silicon photovoltaic cells. Not all photons are absorbed—some reflect off the surface or pass through the material.
