The photovoltaic conversion efficiency, which can be determined from the current versus voltage (I-V) characteristic curves of an illuminated photovoltaic cell (or panel) is an important factor in identifying its quality, performance and efficiency under varying environmental conditions.
Solar Panel Efficiency explained. Solar panel efficiency is the amount of sunlight (solar irradiance) that falls on the surface of a solar panel and is converted into electricity. Due to the many advances in photovoltaic technology over the last decade, the average panel conversion efficiency has increased from 15% to over 24%.
Conversion efficiency, expressed as a percentage (%), depends mainly on the intensity of the incident sunlight hitting its surface and the temperature of the solar cell. Then the efficiency of a PV cell is defined as being:
Then the efficiency of a PV cell is defined as being: Where efficiency, η (eta) is the solar panel efficiency, P MAX is the maximum electrical power, divided by the sum of the panel area (A) in m 2, to the irradiance intensity (E) measured in watts-per-metre-squared (W/m2).
For example, LONGi’s Hi-MO X10 commercial-size module reaches up to 24.8% efficiency and 670W output, while several 700W+ utility-scale modules from Trina Solar, Risen, TW Solar, and Huasun now exceed 24.2–24.8% efficiency, highlighting how innovation at the large-format level continues to raise the bar for the entire industry.
Increasing the panel size can improve efficiency by creating a larger surface area to capture sunlight, with the most powerful solar panels now achieving power ratings of over 700W. What makes the most efficient solar panels? At present, silicon-based monocrystalline panels are the most efficient type available.
