This is good as cold weather usually means shorter days, fewer hours of sunshine. That won;t make up for the greater number of hours os summer sunshine, but it helps. However, along with cold weather and the higher output voltages comes a danger. All electronics have a design range for input voltages; a lower limit and a higher limit. Drop below the lower limit and the unit may just stop functioning until the voltage rises. Exceed the upper limit and the unit may stop functioning permanently. Toast.
