Westport architect works to bring solar power
into mainstream
THE HOUR

Imagine what it would be like not to pay a big electric
bill each month, or how comforting it would be to know
that if the power goes off, you will not lose heat,
water and other vital services in your home.
John Rountree, a Westport-based architect and solar
design consultant for Solar Works of Montpelier, Vt,
has been interested in solar electricity and how best
to use this clean, pollution free energy effectively
in every day life for years.
Rountree's quest is now being realized. As of last week,
one-third of the electricity needed to power his South
Compo Road home and office is being supplied by the
sun, converted to home use by photovoltaic cells. "I
have just installed the 'grid-tied' photovoltaic system
made by Solar Works which makes my house the first house
in Fairfield Country to be partially powered (in this
way) by the sun," Rountree said.
Rountree mounted 12 cell panels on the south side of
the roof which will produce about 1200 watts AC for
his house during sunlight hours. Any excess power made
by the cells is sold back to the utility company. The
house is powered by the utility company at night.
The Solar Works system Rountree chose is supplying one-third
of the electricity used in his 1,200 square foot house
and is saving him one-third of his electric bill while
also providing a back-up energy source in the event
of a power-failure. "Critical loads" such
as the refrigerator, furnace, water pump and a couple
of plugs will stay on.
Rountree, a registered architect since 1986, said he
first became intrigued with solar electricity while
a student at Syracuse University in the early 1980s.
"Solar electricity was first developed in the '50s
to power satellites and space ships," he explained.
"You can't have a gas engine up there, or coal,
or oil — you can't run power lines out there.
Solar cells do it all."
Solar cells are made of melted down silicon with metallic
fingers applied to it. When the sun hits the cell, a
positive charge is created on one side and a negative
charge on the other. Electrons are released which flow
from one side to the other creating a circuit of electricity,
a current, which runs through these metallic fingers.
"I also store power in eight batteries in the basement,"
Rountree said. "When the power goes down, they
automatically provide emergency power for about two
days."
Another advantage of solar power, besides saving money
and having an easy source of emergency power, according
to Rountree, is that no harmful emissions or pollution
are produced. But the solar system is expensive to install,
around 10 cents a watt, meaning a partial system like
Rountree's would cost about $10,000; a complete system
to power an average-sized house would cost about $40,000.
"There is a house in Maine that is completely off
the grid. It can be done. That is what I would like
to see for all houses eventually — that they are
electrically self-sufficient."
Rountree and Solar Works have started an initiative
called "Solar for Connecticut Schools," a
non-profit group that works with the Department of Environment
Protection, United Illuminating and the state Board
of Education. Its mission is to raise private funds
to install photovoltaic systems on 10 public schools
throughout the state.
"It would be an educational tool to help teach
the children and the community about solar energy,"
he said. "We hope to have this accomplished by
the spring of 2000."
