Photovoltaic (PV) technologies – more commonly known as solar panels – generate power using devices that absorb energy from sunlight and convert it into electrical energy through semiconducting materials. These devices, known as solar cells, are then connected to form larger power-generating units known as modules or panels.
Best solar panels for efficiency. Another important solar panel feature is efficiency rating, or how much sunlight a panel converts into electricity.. The most efficient solar cell of any kind has an efficiency of 39.5%, but is designed for space applications, not an ordinary roof.. Residential solar panels typically range between 15% and 20%, with the industry-leading panels pushing 23%.
