The product will provide continuous service year-round. The materials that we use in the construction of the product will hold up well against ice and snow, so you can keep the product outside year-round. The light automatically recharges itself in sunlight and will keep its charge for up to 6 days without sunlight. While not necessary, some may choose to bring the units in for the winter, especially in northern regions where geese migrate to the south. If removed, be sure to turn off the unit while storing inside for the winter. Continue protecting the water by turning the unit back on when returning the unit outside in the very early spring. The unit will deter geese that are present and also prevent geese from settling.
