New parameters to improve prediction models for snow cover

Canadian scientists have developed a way to improve the short-term models used to forecast the impact of snow on PV arrays. The parameters include the warming effect of irradiance on the backs of panels, thermal capacity, and irradiance through snow.

Spanish PV struggling with snowfalls caused by Storm Filomena

While Spain is struggling with the largest snowfall since 1971, pv magazine editor Alejandro Diego Rosell has asked two Spanish experts what the consequences of the massive snow loads produced by Storm Filomena will be on solar installations. According to them, some PV systems may stop working completely and component failures may not be excluded.

Heating solar panels to clear snow

A Norwegian company has developed a way to melt snow on modules to avoid excess weight on roofs and panels, especially on large commercial and industrial arrays. A control system measuring snow density is linked to DC power supply units to warm the panels.
