NOCT (TONC): what it is and how it affects photovoltaic performance

Detalle de una célula solar en un módulo fotovoltaico para representar el parámetro NOCT

The NOCT, or TONC in Spanish, indicates the nominal operating temperature of a photovoltaic cell under reference conditions. This parameter provides a better understanding of the module’s thermal behaviour and its impact on the power output and actual performance of a solar installation.

Albedo in the photovoltaic sector: what it is and how it affects performance

Albedo in a photovoltaic plant with solar radiation reflected onto the modules

Albedo is the ability of a surface to reflect solar radiation. In the photovoltaic sector, this parameter is particularly relevant for bifacial modules, as the radiation reflected by the ground can increase the irradiance reaching their rear side.
