Some How to do it:

Photovoltaic systems present several hazards that are reduced or eliminated by following applicable Codes & Standards.  In Arizona there are no State enforced building and safety codes, this is a local responsibility. Electrical safety is covered by the National Electrical Code that is updated on a 3-year cycle (...2008/2011/2014/2017...).  The photovoltaic specific requirements are in Articles 690 and 705.  Various Arizona jurisdictions have adopted different versions, check with the local building permit to determine which version will apply.

There are also building code and fire code requirements.  Again, various Arizona jurisdictions have adopted different versions, check with the local building permit to determine which version will apply.  California has statewide requirements that have been developed by the Solar America Board for Codes and Standards
(www.solarabcs.org).  The following documents are very helpful in understand how to lay out photovoltaic arrays for safety and fire personnel access:
