Photovoltaic panel efficiency

The efficiency of a PV panel is an important indicator that reflects the ability of a PV panel to convert energy from sunlight into electricity. This parameter is crucial for assessing the performance and efficiency of PV systems. The efficiency of a PV panel is usually given as the percentage of solar energy that the panel is able to convert into electricity from the energy incident on the panel surface.

In the case of a panel with an efficiency of 18 %, this means that it can convert 18 % of the incident solar energy into electricity. PV panel efficiency is a key metric when comparing the performance of different types of solar panels.

Currently, the average efficiency of photovoltaic panels is around 20%. The efficiency of photovoltaic panels varies depending on the type and quality of the materials used to make them, the temperature, the intensity of the sunlight but also the orientation and tilt of the panel or the shading or dirt on the panels.
