McHenry Area Public Library Facilities Manager David Harding walks between the 40 solar panels pointed south, and tilted at an angle of 33 degrees atop the flat roof of the facility on Front Street. Library officials project the panels will save three to 10 percent on the library's electricity bill, depending on how sunny it is.
