How Does Solar Power Work in the Winter?

November 13, 2018

When you think about the winter, usually images of parkas, scarves, boots, and lots and lots of snow come to mind. The sun is not usually something that is associated with the winter weather that will greet us New Englanders in the coming months. So, how exactly does solar work in the winter? Are there special considerations that need to be taken if there are solar energy panels bringing power to your home or business? Let’s take a closer look at winter and solar power.

 

  • Solar panels are not dependent on heat to work, but rather sunlight and the sun’s rays (photons).
  • Solar panels perform very efficiently during the cold winter months since they have a tendency to work at a higher level under cooler temps than hotter temps.
  • Solar panels still work when it is cloudy or overcast.  As long as there is light, your system will convert it into clean energy.
  • Due to the shortage of light during the winter months, your home won’t produce energy for as long as you would during long sun-filled days of summer.
  • Since the sun comes in at a different angle during the winter months, you may be concerned about capturing the sun’s rays. The good news for SunPower by BlueSel customers is that we use high-quality anti-reflective glass that traps incoming light from all angles, capturing more sun than conventional panels.
  • Worried about snow on your solar energy system? Our installers know our panels well. Our panels are smooth and the angle at which they are installed means that snow generally slides or melts off during a typical snow storm. If there is a huge snowfall and your panels are not clearing fast enough we recommend that you hire a professional to clean of the system and your roof.
  • Winter can mean rapid changes in temperature that, for traditional panels, could mean problems. SunPower cells and panels are engineered differently. Our solar cells are designed with no metal on the front. The entire back surface is covered with a thick copper foundation plated with tin. Not only is there much less corrosion happening to the tin-plated copper compared with silver paste used on conventional panels, but it’s also far less likely that the cell will break due to fluctuations in temperature.
