How to install photovoltaic panels at high altitude
The thought of installing solar panels in isolated, snow-bound regions with harsh weather conditions may seem far-fetched but doing so offers an important avenue for reducing pollution and mitigating climate change.

In high-altitude environments, installing solar photovoltaic panels involves unique challenges and techniques that differ significantly from installations performed in flat terrains. 1. Site assessment is crucial, as evaluating the topography and accessibility determines the feasibility of installation.
The basic idea is to use high-altitude platforms to significantly improve the performance of photovoltaic (PV) modules, as solar irradiance increases significantly at high altitudes. Suitable locations for installing solar panels at high altitude are:.
The workaround to undulating topography is non-intrusive mounting options made for slopes, grades and hills. The common solution is extended post length, but installers can make custom brackets or install panels in smaller rows or single-bay tables. GameChange Solar has a history of working in the hilly terrain of the Northeastern United States.
Finally, at a high altitude, a ground-mounted PV installation clearly outperforms the FPV installation. Next to the lower impacts from the mounting system, the open-ground installation has a higher yield than the FPV installation.
6 FAQs about [How to install photovoltaic panels at high altitude]
Why do solar panels generate more electricity at higher altitudes?
Photovoltaic panels at a higher altitude are receiving more solar radiation compared to the sea level, resulting in more generation of electricity.
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.
What makes high-altitude solar panels successful?
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.
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.
Can a solar array be installed on a hill?
No matter where you’re at there’s going to be some sort of undulation,” said Rob Stoll, photovoltaic tracker design manager at RBI Solar. A ground-mounted solar array ascends up a hill. While it’s simpler to install solar on flatter terrain, hills and undulating ground are feasible solar sites. RBI Solar
What temperature should solar PV modules be tested at?
The efficiency of solar PV modules is tested at 25 °C, which is the cell temperature of the Standard Test Conditions (STC). There will be a power loss of about 0.5% for each degree Celsius above 25 °C. Heat is generated in the air by molecules colliding and creating friction.
