A Power Authority rooftop solar system, one of the world's
largest, atop the Gun Hill Road Bus Depot. |
The Solar Electric Power Association (SEPA), a
non-profit association promoting solar power, has presented us with its
Platinum Award for our pioneering work in demonstrating the practicality
of generating electricity from sunlight. In fact, with 27 photovoltaic
(PV) projects under our belt thus far, and a combined capacity of 662 kw, we have the third largest solar demonstration project in the
country, including one of the world’s largest rooftop PV systems (300 kw
at New York City Transit’s Gun Hill Bus Depot in the Bronx. We are
responsible for 40 percent of the solar installations in New York City.
First developed in the mid-1950s, photovoltaic cells
have become popular for a wide variety of applications where no other
electricity source is available. In developing countries, they’re used
for water pumping and irrigation, communications and village power.
Other uses include marine navigation signals and security lighting in
remote areas. The worldwide market for photovoltaic systems has
increased by 15 to 20 percent a year in the last decade, as their cost
has become more competitive with traditional, grid-connected electricity
supplies. The data on photovoltaics we’re compiling today will help
expand the use of this technology tomorrow.
Photovoltaic systems convert sunlight directly into
electricity, using panels made of wafers or thin films of semiconductor
materials such as silicon. These systems are totally non-polluting and
silent, have no moving parts and are highly reliable. Since they consume
no fuel and are nearly maintenance-free, their operating costs are
negligible. In addition, they produce the greatest amount of power on
long, hot summer days, when demand and the cost of power are highest.
Besides offering energy-efficiency and environmental advantages, solar
electric systems help local economies by creating jobs as development
and manufacturing opportunities increase.

Solar photovoltaic system at NYPA's White Plains headquarters
building. |
Sitting atop NYPA’s White Plains office building, this demonstration project consists
of 20 solar panels measuring 26 square feet apiece, for a total size of
520 square feet. The system delivers 5.5 kw to the office building.
In addition to installing solar-power facilities at our White Plains office
and the Gun Hill bus depot, we’ve installed
PV systems at other public facilities from Long Island to Buffalo. (List
