Short summary
We tested solar regulators to find their suitability for use in powering instruments in the polar regions. We found that some models waste a lot of power and may result in instruments failing during the wintertime. We developed a model to illustrate this effect, and use it to show that a good choice of solar regulator means a greater chance of successful winter data collection and allows the use of a smaller, lighter, cheaper battery.
