And this is assuming that somebody offers a rail layer on top of another rail layer solution. This will of course cost more money, not to mention having the panels placed a bit higher than normal. The bottom layer of rails is perpendicular to the trusses, and the top layer of rail can sit on the bottom rails and be parallel to the trusses and still be placed for correct spacing. The only way to solve this is to have 2 layers of rails. If you run the rails parallel to the trusses, your rails must be right on the trusses or else there's no mounting point, and this doesn't allow flexibility on where the spacing between the rails can be. The first part that makes sense is that if you have the rail perpendicular to the trusses, you can control the exact spacing of the rails from each other. I asked why can't you mount the rails perpendicular to the trusses and also mount the panels in landscape and they said that voids the warranty from the manufacturer (SunPower in this case) as the rails have to be mounted parallel with the short side (perpendicular to the panel).Īny truth to this or are these guys full of crap?Actually what they said makes a lot of sense to me. The correct way to do it is run the rails perpendicular to the trusses which means the panels have to be mounted portrait.' 'Installing panels in landscape mode means you have to run the rails parallel to the trusses which is not good for the roof. You'll probably want this header on pages placed in your notebook, but not on graphs submitted for publication.I spoke with this company again and here is their claim.

Print the sheet name as header - Print the sheet name, file name, and date on each page as a header.

Print row and column labels - When printing data tables, print the row numbers on the left of every page and the column letters on top of every page.

Print grid lines on tables - Check this box to include the horizontal and vertical lines on data and results tables.

These options on the File & Printer tab of the Preferences dialog affect printing of tables. Reduce column widths by positioning the cursor between column headings, and dragging to squeeze more onto each printed page. While you can change graphs and layouts from portrait to landscape orientation, you cannot o so on data or results tables. A single setting applies to all data tables, results sheets, and info pages in the entire project. Go to File… Printer Setup for Windows (File… Page Setup for Mac).

Save paper, with some tables, by changing the Landscape/Portrait orientation when printing data tables, results, and info sheets. When working with a graph or layout, these buttons simply zoom what you see on screen, but do not change the actual size of the graph or layout when printed.

When you are working with a table, the zoom buttons change the actual size of the font used, which will then change the size of the printed table. Note these buttons work differently in data and results tables than they do in graphs and layouts. Or use the keyboard shortcuts: Use Smaller Font (Ctrl-J), Use Larger Font (Ctrl-M) Change the font size to control the size of the print on the page, and thus the number of pages needed to print a table.
