Your solar PV panels are made to withstand year-round climates and conditions. Solar panels produce power based on the amount of sunlight the panels are exposed to, so they are unaffected by temperature. Those sunny, yet cold days in winter could generate comparable amounts of solar energy to a hot, summer day. Although you won’t be producing as much solar power in the winter as you do during the summer months, your system is designed so that you can draw on the electricity credits you generated during the summer.
