Today, the majority of commercially available solar panels have efficiency ratings between 20% and 22%, which means they can convert about one-fifth of the available sunlight into energy. Higher efficiency means: How Is. . Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. All currently available PV modules (such as solar panels) which convert sunlight into electricity use solar cells to achieve the. . Today, most panels are at least 20% efficient, but the best ones convert over 22% of the sun's energy into electricity.
