“Sweden may seem an unlikely location for a solar revolution, but the lack of light during the winter months was one of the reasons for Exeger co-founder Giovanni Fili to look beyond the Sun as the sole source of power for a photovoltaic cell.

It can even generate a charge from moonlight, though it would take a while for it to be of much use.”
