What are full, 3-line electrical solar system diagrams?

Description and examples of full electrical line drawings for Solar PV Systems

(Above example shows 3-line diagram for a dual inverter grid tied residential solar system)

A full, or 3-line electrical line drawing is often required to obtain a permit for grid tied solar system installation.  Required for permitting or not, 3-line diagrams are always highly valued during installation for their detail, showing wire sizing, routing, and precisely where each wire actually lands on each component.  Line drawings show all circuits and components, but not the actual location of those components, which will be directed by the needs of the local site.
Many permitting jurisdictions only require less informative single-line drawings, however we have found that single-line diagrams take only slightly less time to draw, and are much less helpful to your or your installer.  As a result, SimpleRay only offers the better 3-line full electrical drawings which provide a fast, easy understanding of the connections and use of components.
