Extreme Wind Loading on Flat-Roof-Mounted Solar Arrays with Consideration of Wind Directionality

Area-averaged Characteristics of Wind Loads on Roof-mounted Solar Arrays

With the increasing use of solar photovoltaics, wind-induced loads on rooftop solar arrays have become a problem. A series of wind tunnel experiments have been performed to evaluate wind loads on solar panels on flat roofs, mainly focusing on their area-averaged characteristics such as mean and negative peak force coefficients, and peak factors. Solar array models were fabricated with pressure ...

Rooftop Solar Arrays and Wind Loading

Head Mounted Wind

Within the context of tele-presence and immersion for piloting light aircraft, knowledge about the surrounding wind offers useful information for piloting purposes. Rendering wind in virtual simulation or telepresence application has been used still the early sixties [1] to enhance immersion. However since then it has been rather limited to use a fan in front of the user to produce an illusion ...

Lightning Protection of Roof-mounted Solar Cells

Working paper developed for a NASA-sponsored study of solar cells Significance Part 6: Tutorials, textbooks and reviews Lightning interception by an unprotected building 30 feet high x 45 feet long on flat land, in the Cleveland area, can be estimated at one strike per 200 years on the average. However, peculiar configuration can easily affect this estimate upward or downward. Means are availab...
