Though hopefully winter weather is over for
now, one question we hear often in winter is “how does the snowfall affect my
solar system panels?” Many homeowners who are considering solar installation
may also think of this question, given the sometimes heavy snowfall we receive
here in New Jersey and Pennsylvania . Don’t worry, even when snow prevents us from doing much
outdoors, it really doesn’t hinder your solar system panels from generating
electricity for your home.
With roof mounted solar system panels,
generally the easiest (and often safest) option is to do nothing. Don’t risk
injury or a fall while climbing the roof to clear your solar panels, because
it’s really not necessary. Your solar system panels will clear themselves in
just a short time. During a light snow, it’s ok to brush off your panels if
conditions are safe to access your panels.
Even with a thick layer of snow piled up on
top, your solar system panels are still absorbing the sun’s ultraviolet rays.
As the panels are collecting solar energy, they naturally heat up, which melts
the snow and ice which may be sitting atop them. Solar system panels which are
darker in color stay warmer for longer periods of time, continually melting the
snow. Usually, the panels will have melted all the snow and ice cover in about
a day.
Snowfall doesn’t necessarily hinder your
solar system panels from producing energy during the winter months. In fact,
the snow surrounding the panels and your home may cause your panels to generate
extra energy. Have you ever noticed how bright a sunny day can be with a snowy
landscape? The sun’s rays reflected off the snow can direct more energy towards
your solar panels for absorption.
