Despite the media’s attention to photovoltaic solar panels, there are many types of solar panels,
each of which produce energy in different ways. Different technologies, including traditional
photovoltaic cells, thin
-
film photovoltaic technology, solar the
rmal energy,
and concentrated solar
power technology,

can be used to create heat or electricity
but are dependent

on the community that
they ser
ve due to the footprint of the installation. In order to
introduce solar power

effectively
, the
efficiency must
be up to par
.
Photovoltaic cells are used traditionally on solar panel farms as well as
decentralized installations such as roofs of residential areas and on top of tall buildings

(Roberts)
.
The
problem with these cells is that “efficiency is still only 20
+%, resulting in large land areas needed for
significant electricity output” (Roberts). Thin Film Photovoltaic cells act similarly to traditional
cells and
benefit because they can be applied to more places such as windows, and complete rooftop application
s
meaning greater surface area coverage, but because they are th
in, they are inefficient and expensive

to
produce making their cost outweigh their benefit. In order to increase the efficiency of solar power, a
recent technology has been developed to increa
se photovoltaic concentrations in panels

by using
concave glass to concentrate light onto the superconductors
. This technology increases efficien
cy to as
much as 43% making it much more viable for power production in urban areas where a smaller footprint
i
s needed (Roberts).

Lastly, a

new type of solar energy has been in development
f
or centralized power
called solar thermal energy. The plant works by reflecting light instead of absorbing it and heats up
water to spin a turbine. This design has proven to be

expensive and maintenance

intensive on a larger
scale and even though it is

easier to manage on a smaller scale
, not enough heat is
produced

to create
steam
.

In order to implement a solar infr
astructure in an urban setting effectively, the solution needs
to
have high efficiency and a small footprint. Of all of these solutions,
powers from concentrated
photovoltaic cells or concentrated solar thermal energy seem to be the most practical. The Condensed
Photovoltaic solar panel (CPV) can be easily implemented

in retrofitting existing buildings by
constructing them on the roofs of residential areas and flat roofed buildings. ”The CPV advantage over
these other systems involves a smaller footprint because the solar panels are made of multi
-
junction
solar cells w
ith concentrating lenses, rather than flat silicon cells”

(Roberts)

meaning that with the same
number of installations as traditional solar panels, they produce over twice as much power.
T
he benefits
of understanding different

types of solar technology inf
luence the success of
appling

solar technology to
an urban area and the cost of the project.

The key to an effective fundraiser

is to convince the group you are targeting that their donation
will contribute to the community they belong to. In order to do so
, the externalities affected by the
campaign must be thoroughly communicated,
brochures and other media must be created, and lastly,
budgeting to avoid spending raised funds on marketing. When communicating to the community the
contribution, the project mu
st make their mission clear by addressing “
the organization’s unique ability
to fill the demonstrated need of an identified constituency, affirm the efficiency of campaign planning,
instill a feeling of intrinsic personal reward to the donor, and, very imp
ortantly, convey a sense of
urgency” (Poderis). The campaign should connect the targeted individuals

by illustrating what they will
receive or help others receive by donating
. Secondly, campaign media must
incorporate the case
presented and go the extra st
ep to show how people can contribute (Poderis). The media created will
also help in the next step, budgeting and publicizing. One of the
most important steps

“if left
unaddressed, could result in a disregard for what is actually a key fundraising tool” (
Poderis). When
working on a fundraising project, there is a tendency to forget about the fundraiser and focus on
advertising if so when the fundraiser comes, there is no fundraiser, or it is unsuccessful. The article is
critical for the project to ensure
that the fundraiser has the right balance of advertising and budgeting.
For our project, we will be minimizing as many costs for the fundraiser to benefit the purchase of solar
panels for the
lampposts
.

For advertising, we will most likely need to market t
he fundraiser to the
community by illustrating the benefits of the solar panels we are working to purchase. When attached
to the grid, these solar panel lampposts will be sustainable in the city by producing energy for the
people during the day and illumin
ating the city from the created power at night. Our brochures will be
homemade but professional in order to save money rather than hire a campaign manager for the
project. It will also help to present various things such as food for the people who contribu
te to give
them not only the promise of a more sustainable city, but also give immediate gratitude to eat while at
the fundraiser. Lastly, our hope is that the model of our fundraiser can be implemented and Troy can
become a model city for sustainability.

The model for the project is based loosely on the recent construction of ‘supertrees’ in
Singapore.
To promote
flora and fauna, Singapore funded a project to construct solar powered trees.
The trees

were designed “
operate as temperature moderators, absorbing and dispersing heat, as well as
providing shelter from the hot temperatures of Singapore's climate to visitors walking beneath”
(Moorhouse).

The structures were constructed on reclaimed land near

the water.

One of the major
features of the trees is that they act as city gardens clearing some of the air
. The design incorporates
water cooling systems and sustainable solar energy production
.


The horticultural oasis will be a
contrast to the
country's extremely dense urban environment, forming part of the government's overall
strategy to transform Singapore into a ‘city in a garden’” (Moorehouse).

The goal of the solar power
biomes is to promote sustainability in an urban setting, the same thi
ng this project will accomplish by
installing solar powered light posts
.


The man
-
made mechanical forest consists of 18 supertrees that act
as vertical gardens, generating solar power, acting as air venting ducts for nearby conservatories, and
collecting r
ainwater. To generate electricity, 11 of the supertrees are fitted with solar photovoltaic
systems that convert sunlight into energy, which provides lighting and aids water technology
within the
conservatories below” (Moorehouse).

The design is similar to
ours in that we are both looking for a way
to implement a sustainable green solution that has a small footprint
.
While the Singapore model was
much more extensive, our model for sustainable urban modernization similarly follows their model
.
Both our model
and their model will be implemented as part of the electrical grid so energy produced
will not only be used to sustain itself but the city when they over produce power
. One major difference
is where we are receiving money. Our goal is to fundraise for the
purchase of the panels and raise
awareness about being green in the process

where Singapore received government funds to construct
the large sustainable trees. To keep our project in perspective, the solar panels on the street lamps
should be much cheaper
to implement since we do not need to construct a
structure that large
.

Our
plan will hopefully extend to multiple cities and we could possibly place a small ‘solar tree’ in the Troy
park to contribut
e

to the energy generated by the solar lampposts.
