[The first in our 2-part series on vertical solar.] Upright solar innovations that are radically different from – and take up far less space than – garden-variety solar farms may well revolutionize the industry in the next few years. Some vertical panels can capture light far longer than horizontal ones, as they can continue to produce power even as the sun is low on the horizon. As with the image of humanoids learning to stand upright, vertical just might be the next step in the evolution of solar.
