However, technological advances have made it possible to use solar energy at higher altitudes and latitudes using higher-efficiency panels, also referred to as high-altitude photovoltaics. CLOU is participating in a large scare research project in the Sichuan province, 3900 m to 4500 m above sea level.
One point that comes out clearly is that, when you embark on the challenge of high-altitude solar panels, the key to success is a holistic approach that accounts for local climatic and topographic variables, while bringing tested engineering solutions to the fore.
With rising height, solar UV radiation increases while the amount of air molecules, ozone, particles, and clouds above the surface decreases. Previous research has shown that solar energy harvesting at high altitudes is more effective than at sea level. There is less dispersed radiation and more direct radiation.
At the same time, air ventilation will cool down the panels, which are getting hotter by generating more power than on lower ground. PV panels at a higher altitude are receiving more solar radiation compared to the sea level, resulting in more generation of electricity. CLOU is very proud to be part of the research base.
There are many high-altitude developing countries across the world with solar potential, Armenia and Serbia to name a couple. Yet, despite the clear skies and low temperatures in snowbound, hilly regions that may be conducive to solar photovoltaics, installation in these areas is no easy task.
Overall, our results suggest that high-altitude floating solar technology should be on the global radar for alternative utility-scale solar electricity technologies. The prospect of utility-scale production and homogeneous spaces presents the technology as a solid option for large-scale expansions in mountainous regions.
