Future va
alue to the en
ngineering profession:
p
As engine
eers we are constantly
c
striving to design solutions to
o our clients’ problems in w
ways that are
e both
economic
cally practical and technica
ally efficient. We
W optimize designs to m
make systems more efficien
nt and
also look out for the public’s
p
healtth and safety
y. This proje
ect provides ffuture value tto the engine
eering
profession
n because it represents th
he integration
n of new tech
hnologies into
o existing stru
uctures. By a
adding
the PV pa
anels to an ex
xisting roof to
op we are ab
ble to increase
e and diversify the use off the structure
e. The
addition of
o the PV pan
nels provides shading for the
t existing ro
roof, thus reducing the dire
ect heat loading of
the rooftop.
Land
d is a valua
able commod
dity in
our state and for that re
eason
purcchasing of ssuch land willl add
costt to the botto
om line of thiss type
of p
project. By u
utilizing an exxisting
shopping centerr’s roof spacce our
clien
nts were able
e to not distu
urb an
exissting parcel of land forr this
project while incrreasing incom
me for
the building own
ner and usin
ng an
under-used spacce. As a rresult,
additional enviro
onmental im
mpacts
were
e avoided.
Phase II looking wes
st
nd economic consideratio
ons:
Social an
Given the
e increasing needs for morre power gene
eration to sup
pport our natio
on’s economyy and currentt push
to provide
e alternative, clean renew
wable energy
y sources, th
his project is positively co
ontributing to
o very
sensitive social and ec
conomic pres
ssures that our Nation facces today. Florida isn’t ca
alled the Sun
nshine
State by just
j
luck it is a fact of life,, particularly in Gainesville
e Florida whe
ere it average
es over 220 ssunny
days a ye
ear. As a result this projec
ct takes advantage of our natural clima
ate and adds to domestic p
power
generation and a reduc
ction of the de
ependence on
n foreign sou rces of oil and
d natural gas.
Complexity of the pro
oject:
The existting buildings used to sup
pport the PV system are metal framed flat roof sttructures. The
e roof
diaphragm
m is supported with meta
al bar joists covered witth metal deccking, rigid in
nsulation and
d roof
membrane. The roof su
urface is apprroximately 27
70,000 ft2 in a
area with a va
ariety of roof to
op equipment. The
panels were
w
placed around the equipment with
w
approprriate opening
gs for equipment accesss and
maintenan
nce.
The PV system
s
installe
ed for this ap
pplication is a roof mounte
ed self-ballassted system that did not re
equire
roof mem
mbrane penettrations. The
e PV system uses a raccking system that include
es ballast we
eights
designed to resist requ
uired wind up
plift loadings per the Florid
da Building C
Code (FBC). A
As part the d
design
services we
w conducted
d an analysis of the roof strructure to sup
pport the incre
eased loading
g due to the a
added
panel weight associate
ed ballast and
d wind loading

incorporatted existing buildings, parapet
walls, arc

solstice. Panel groups were then laid out to
optimize sunlight
s
expos
sure on each panel groupings.
The shad
ding analysis was essentia
al to the elec
ctrical wiring design of th
he project. E
Each panel “sstring”
consists of
o 14 panels connected
c
in series. If one
e panel is sha
aded the entirre string could be out of se
ervice
and thus rendering the
e other 13 pa
anels useless
s in power pro
oduction for tthat shade pe
eriod. This d
design
incorporatted such cons
straints on the
e wiring of the
ese panels to
o reduce the p
potential of su
uch problems.
This desig
gn also incorp
porated inverrting and phas
sing the direcct current (DC

by the solar p
panels
into the alternating currrent that was
s necessary to

n with
Gainesvillle Regional Utilities (GR

sential in ord
der to prope
