an online information section. They also may have forms that can be downloaded to
your computer. You may be able to download the process and paperwork informa-
tion before you call. The local building department will offer the hard-copy permit
application as well as guidance about the process, if requested. City or county permits
are required prior to installation. Structural and electrical permits often are issued
separately when applicable, and many jurisdictions have differing requirements.
The individual responsible for obtaining the permits—whether from the
PV design firm or the installer’s organization—gathers all necessary documenta-
tion for the permits.
Most permitting jurisdictions have different fee structures for permitting
PV or any other electrical system. Sometimes it is a flat fee. Sometimes it is a plans
review and permitting fee. During the design phase, check the permitting costs.
Find out how the fees in your area are calculated.
Permit costs often are based on the entire PV project cost, but not always.
Permit costs can go up in price. The increase in price usually occurs when permits
need to be expedited, or if you have to make changes to the system or site loca-
tion. Every AHJ will have different approaches to permit fees. Many communities
are developing alternative scales for permit fees. The alternative scales are based
on policies that support and encourage PV systems.
The permitting process usually requires:
1. A permit application
2. Supporting documentation
3. Payment
4. Plans review
5. A call to schedule an inspection
6. Inspection
7. If changes are required by the inspectors, submission of an updated set of
plans, called as-built drawings
Securing a Permit
After selecting the size and design of the PV system, gather all the necessary
paperwork and documentation. You need this information to secure the building
permits necessary to install the PV system. No PV system can be installed without
permits. Otherwise, there will be fines and other costs. These permitting costs are
in addition to the PV equipment costs.
Contact the local building safety department. It is responsible for permitting
PV systems. It is also responsible for inspecting permits and construction work in
a city or county. Work closely with local AHJs and other building officials.
AHJs enforce building codes. They also specify the materials and equipment
to be used. The AHJs may also specify wiring and safety measures. They inspect
NOTE
Do not begin installation of a PV system
without purchasing a permit.
