That sounds like it could be actually helpful in a way. During winter, the solar panels are expected to generate a lower voltage, which means that they couldn't help in recharging full batteries for instance. But since the temperature drops, so does the apparent voltage from the batteries, allowing the electricity from the solar panels to flow even if they generate a lower voltage. I believe the batteries' charging efficiency also decreases, though, but at least it could allow them to "stay put" through the harsh winter.
