The holes you drill today determine whether those panels will still be there after the next nor'easter. 5-1mm clearance around bolt shank (not threads!) Last summer, we watched a crew use clay tile bits on standing seam metal. The resulting Swiss cheese roof cost them. . When designing a PV system that is tilted or ground mounted, determining the appropriate spacing between each row can be troublesome or a downright migraine in the making. Even small amounts of shading can reduce your array's output and lower system efficiency. This includes factors such as light reception, heat dissipation, and ease of maintenance. Orientation Adjustments: In some cases,adjusting the orientation of the panels (from south-facing to east-west orientation,for example) can help in reducing the spacing ms on horizontal and non-horizontal planes. Formula: Spacing = Height / tan (Solar Altitude). Solar altitude depends on latitude, tilt, and solar declination for the selected date.
