Solar Panel Glare Analysis

Glare occurs when sunlight is reflected off of a flat shiny surface.

Testing shows that eclipse provides high quality engineering analysis faster than other comparable tools and we continually benchmark it against real world data. Photovoltaic panels actually cause less glare than standard home window glass. The important results of glare analysis are summarised in table 1. In an international comprehensive analysis of potential glare hazards pdf see section 7 in aviation from solar panels the uk s spaven consulting points out that a trawl of uk and us aviation incident databases between the years 2000 and 2010 for accidents in which glare was cited as a factor reveals that in the overwhelming majority of these cases the source of the glare was the sun itself.

Photovoltaic panels produce less glare than standard window glass. The potential ocular impact from the observed glare is also determined along with a prediction of the annual energy production. Fresh snow reflects 80 95 and black asphalt only 5 10. The duration of glare on atct from solar modules installed in a pv is 6778 min green and yellow glare.

Forgesolar is the premier toolset for evaluating photovoltaic glare. But for this location the flight path receptor is safe from any kind of glare impact that can be attributed to the selected location and panel orientation. In case of reflectivity of a pv array it will be a function of its albedo as in case of any other surface. It can be observed that solar panels installed in the area a pv cause glare and hence this location is not suitable for solar projects in the given system design.

Solar panels are flat and somewhat shiny but they are designed to capture light not reflect it. Our custom tool for simulating the sun called eclipse gives fast and accurate estimates of glare impacts and risk potential. Forgesolar tools are used throughout the world by industry academia and military to evaluate pv glare.
