Are photovoltaic power plants feasible at high altitude?

The rising demand for sustainable energy requires to identify the sites for photovoltaic systems with the best performance. This paper tackles the question of feasibility of photovoltaic power plants at high altitude. A direct comparison between an alpine and an urban area site is conducted in the south of Austria.

Can solar energy be used at higher altitudes?

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.

How does high altitude affect solar energy harvesting?

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.

Why do solar panels get hotter at higher altitudes?

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.

How does a photovoltaic power measurement system work?

Two low-cost automatic photovoltaic power measurement devices with dual-axis sun tracking and maximum power point tracking are deployed at two test sites. The system periodically performs a scan over the southern semihemisphere and executes maximum power point adjustment in order to assess the performance for a given direction.

How can high-altitude floating solar improve site profitability?

Combining high-altitude floating solar with storage technology would also increase site profitability by enabling the sale of generated power at higher prices. This may be achieved through integration with associated hydro pumped-storage facilities.
