Bear in mind too in winter the days are shorter, sunlight is weaker, and you're using *aaaaaaall* of the electrical goodies. Even down south here at 56°N there's about five hours of sunlight in winter and as you get further north it just gets shorter. That's about enough charge to get the length of a supermarket car park.
