How are we going to achieve?
• Focus on:
– Planning & Zoning
– Finance
– Outreach
– Permitting
Big Focus Area- Permitting
•
•
•
•
•
•
One permitting solution across municipalities
Online Permitting Application
Pre-engineered design plans
Permit issued in minutes
Net metering collaboration with FPL
Training for stakeholders

What Does FSEC Do?
• FSEC is the energy R&D institute for the State of
Florida
• Required by Section 377.705 of the Florida Statutes to
develop standards and certify all solar energy
equipment manufactured or sold in Florida
• 140 highly qualified staff members
– Largest and most active state energy research institute of
its kind in the U.S.
– 32-year history of research, education, testing and
certification excellence

Rooftop Arrays
•PV arrays are generally
mounted in the same or
parallel plane to the roof
♦ Aesthetics
♦ Wind Loading
♦ Energy production
variation is not significant
for typical roof slopes

Two general categories for roof mounted PV arrays
1) Above and parallel to the
roof plane
2) At a tilt relative to the
roof plane

Design Loads
• UL 1703 describes the
structural loading tests for
PV modules
• Minimum design load
30 psf* 1.5 = 45 psf
• The Design Load can be
greater if specified by the
manufacturer
Figure from UL 1703 Test Standard

Current Codes and Standards
• Sample design
calculations have been
developed for parallel
arrays
• Work has begun on a
method for more
complex geometries
27

Guidance is Lacking
Frustration,
uncertainty,
inconsistency, and
gross negligence will
result from the current
lack of guidance.
Particularly in high
wind regions.

Truss Attachments
• Pilot holes should be
drilled (correct diameter)
• Centered on truss
33
FLORIDA SOLAR ENERGY CENTER — A Research Institute of the University of Central Florida
Attachment to Trusses
• High-quality, roof-compatible caulk should be applied
before attaching the mounts to roof
34

Attaching the Array Rack
• Additional piece provides a point of attachment for the
aluminum rack
• Aluminum rack is then placed over the bolts protruding from
the mounting hardware.
35
FLORIDA SOLAR ENERGY CENTER — A Research Institute of the University of Central Florida
Securing Rack in Place
• Once the rack distance has been determined, the rack
can be fastened to the roof attachments.
36
FLORIDA SOLAR ENERGY CENTER — A Research Institute of the University of Central Florida
Module Fasteners
• Special assemblies are then
used to attach the modules
to the rack.
 These assemblies slide in the
groove at the top and bottom of
the rack and clamp the
aluminum frame of the module in
place.
37
FLORIDA SOLAR ENERGY CENTER — A Research Institute of the University of Central Florida
Attaching the Modules
• The aluminum frame of the modules then slips under
the clamps and are secured with a bolt and socket
wrench.
38

Wiring Modules Together
• Once the array is installed, the modules can then be
wired in series using the quick connects provided
with each module.

Goals
• Fast and efficient permitting
• Code compliant electrical designs
• Strong and safe structural designs
• A Growing Solar Industry in Florida

Agenda
• Net Metering – definition and requirements.
• FPL’S Net Metering Customers.
• FPL’s leadership in renewable energy.
• FPL’s PV rebate program.
• Sources of information.
49
Net Metering provides a means for FPL Customers to earn a
payback from connecting approved renewable energy
systems – such as solar panels - to the electric grid.
Net Metering
• All applicants must submit:
– An Interconnection Application
– An Interconnection Agreement
– A completed Building Permit
• Systems larger than 10 kW AC must also:
– Pay an application fee and provide proof of insurance.
Note: Fee and insurance amount depends on size of system.
– Install a visual manual load break disconnect switch.
• All inverters must be listed to U.L. 1741.
All FPL paperwork and instructions for interconnecting are available online, by mail, or fax.
50
Net Metering measure both energy used from the grid, and
excess energy produced that is sent to the grid
FPL’s meter only measures the “excess energy” sent to the grid, not the
total energy produced by the PV system.
51
FPL has renewable energy customers throughout its service
area.
