Some of the coldest places on Earth, including the high altitudes of the southern Andes and the Himalaya, could also have the best potential for solar power using
photovoltaic technology, a new study finds. In a global assessment of photovoltaic potential, researchers found that high-altitude regions could generate high levels of solar power not just because they are sunny — and thus are exposed to high levels of solar irradiation — but also because the low temperatures actually improve the performance of some solar panel technologies. For example, developing solar plants within just 4 percent of the Himalaya’s high-potential region — or about 12,000 square kilometers — could provide enough power for all of China, according to the study. While the high cost of installing solar plants in these remote regions would currently make large-scale projects impractical, the results could provide an incentive for small-scale projects in remote, rural areas, said Kotaro Kawajiri of Japan’s National Institute of Advanced Industrial Science and Technology and lead author of the study published in Environmental Science & Technology.
