A Study of the Hazardous Glare Potential to Aviators from Utility-Scale Flat-Plate Photovoltaic Systems

الملخص EN

The potential flash glare a pilot could experience from a proposed 25-degree fixed-tilt flat-plate polycrystalline PV system located outside of Las Vegas, Nevada, was modeled for the purpose of hazard quantification.

Hourly insolation data measured via satellite for the years 1998 to 2004 was used to perform the modeling.

The theoretical glare was estimated using published ocular safety metrics which quantify the potential for a postflash glare after-image.

This was then compared to the postflash glare after-image potential caused by smooth water.

The results show that the potential for hazardous glare from flat-plate PV systems is similar to that of smooth water and not expected to be a hazard to air navigation.
