Asce 7 10 solar panels.
The provisions contained within asce 7 10 for determining the wind loads on rooftop equipment on buildings is limited to buildings with a mean roof height h 60 feet.
This paper will show how to calculate for wind and snow loads using both design principles.
Drawing from published case studies and their own extensive experience with solar panels o rourke and isyumov present recommendations that are compatible with snow load procedures in minimum design loads and associated criteria for buildings and other structures including the asce 7 load factors thermal slope and exposure and asce 7 load.
Required 10 inch minimum distance from roof edge or ridge height above roof between 2 inches and 10 inches minimum gap of 0 25 inch between adjacent rows of panels in earlier version of ac 428 minimum gap was 0 75 inch.

The design is in accordance with seaoc pv2 wind design for low profile solar photovoltaic arrays on flat roofs by structural engineers association of california and with asce 7 10 for solar photovoltaic arrays on pitched roofs like gable and hipped roof.
Section 29 4 4 covers the other roof slopes.
Model building codes have used asce 7 05 as the basis for several years which largely follows the design principles of allowable stress design.
Recently asce 7 10 was published and has become the basis for the 2012 series of the international codes i codes.
For example asce 7 16 now clearly states that the weight of solar panels and their support are to be considered as dead loads 1 roof live loads need not be applied to areas covered by solar panels under a certain spacing or height 2 and seismic design is based on already established principles in section 13 3 for non structural component.
