What is the primary benefit of a PV array installed at a higher elevation?

The primary benefit of a PV array installed at a higher elevation is the reduction in shading. When solar panels are installed at higher elevations, they are less likely to be obstructed by surrounding structures, trees, or other objects that can cast shadows. This reduction in shading is crucial because any shading on the panels can significantly decrease their efficiency and overall energy output.

While elevation can have some impact on voltage due to variations in the altitude and atmospheric conditions, the most significant benefit directly associated with increased elevation is ensuring that the panels are exposed to maximum sunlight. By minimizing shading and maximizing direct sunlight exposure, the array can operate at its optimal capacity, ultimately increasing energy production.

This understanding underscores the importance of site selection and installation practices in solar energy systems to achieve maximum efficiency and energy yield.
