They use LPG for heating and cooling already. The battery isn’t needed for that, so a wood stove wouldn’t change anything. Their primary issue is that there just isn’t much sun light in the winter. Not only is the duration very short, maybe 7 hours total per day, but the angle of incident is extremely low (sun doesn’t rise very far), making shading a serious issue. Conversely electricity consumption will be higher because lights need to be on longer, due to the reduced daylight hours. To top it all of, be so far north also means the intensity of sunlight is lower, so the energy delivered by a each sq meter of solar panel is lower compared to a similar panel near the equator. Put that all together, and collecting enough energy for functional illumination, and pumping water can become a real challenge.
