A 36 inch pathway must be available spanning from the bottom roof edge to the ridge. Aurora lets you add your jurisdictions setback requirements into your solar panning database (see this article for step-by-step instructions), and these setbacks will be displayed as your employees design individual projects. Use design guidelines that minimizes the total amount of conduit used on the roof by taking the shortest path from the array to the DC combiner box. In the event of a fire and if roof top operations are employed a fire fighter needs to be able to traverse on the roof quickly hence the needs for the breaks.
