Yes, our solar lights are designed to be used outside all year in various weather conditions so it's ok in the rain. However, if it’s in an area on the ground where the water will pool up then you may need to move it as a precaution so it’s not submerged in water. It can also be left outside in the winter with snow and ice. However, if you know it’s about to be buried under snow for a while you may want to move it as a precaution then put it back outside when the snow clears. If not, you’ll need to clear the snow off the solar panel so that it’s able to recharge. Also, you may want to adjust the direction of the solar panel seasonally to get the most amount of sun possible since the sun can be at a different angle in the winter.
