Solar panels are designed to shed snow.

Snow melt for solar panels. When snow accumulates on panels owners are advised to let it melt. Use solar radiation for snow melt systems. Solar panels can cause snow to slide off your roof in sheets. Most solar panels are installed at an angle and face the sun which helps the panels to.

What can i do about the snow. In worst cases snow can weigh over 200 kg m. Solar panels continue to work well in the winter as long as they don t stay covered in snow. Many industry experts recommend you do not attempt to remove snow from solar panels.

Snow has anti soiling properties and hence when it melts it takes with it any dirt on the panels. Photovoltaic units installed in heavy snowfall regions are generally facing two areas of concern.

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. In this month s column we ll begin looking at solar thermal energy as an alternative to conventionally heated systems.
