How Solar Works
The sun provides free energy to your solar panels which use it to create DC current.
You are always connected to the electric grid so you have power at night when your panels aren’t producing.
Power travels through the inverter which converts DC to a usable AC current.
AC power travels through to your electrical box which directs the current to all the appliances in the home.
Your utility meter measures production. Any over-production will spin your meter backwards, credit you for the output current, and send unused energy back to the grid.
Solar Panels in the Winter
Glass coating on top of panels allows snow to slide right off.
Panels are angled at about 14 degrees, also allowing anything to slide off.
Because of the electronic components, although not a lot, the panels heat up a few degrees. This is just enough to melt the snow on top.
Rain and snow on panels actually help because they clear off any dust and debris on top.
UV (ultra violet) rays are still able to penetrate through clouds in the winter.
