Why not sunslates?

Sunslates are the most aesthetically pleasing way to do PV. The advantages are that it is almost unnoticeable as PV (no attractive nuisance), it uses the same Sharp cells as our panels (very efficient technology), It is a little more expensive as you are getting a 50 year roofing material as well. Sunslates work best on clean, open, rectangular surfaces with no vent pipes, chimneys or dormers.

Sunlight falling on the solar shingles produces direct-current electricity. Under the best conditions of temperature and humidity, each shingle produces 17 watts on a clear afternoon.

Photovoltaic panels have been used on satellites and space stations over the past decades. The roof shingles are their new brothers, manufactured flexible film, rather than hard plates, and made into shingles. Engineers call it "thin-film technology."

In building the garage, the contractor coordinated with a solar engineer, Bryan Walsh of Solar Connexion in Blacksburg, Virginia. The contractor installed the regular shingles to precise measurements, leaving room for the solar section. Later, the engineer fastened the photovoltaic shingles in place atop the black felt that is the successor to the tarpaper of days gone by.

Walsh then ran the electric wires through the roof. Such shingles are manufactured by several companies. The ones he used on roof are Unisolar products and are guaranteed for 20 years.

The small wires are connected along the garage ceiling, and run to an inverter, which turns direct current into alternating current for household use. The wire from the inverter goes to the ordinary circuit-breaker box (at right) before going on to our house.
Using photovoltaic panels to generate some of the electricity the house consumes reduces the need for power delivered from the grid of the local power company—in this case, the Rappahannock Electric Cooperative. Homeowners can install a bank of batteries to store electricity during the day for use at night. However, in this project, we chose to, in effect, use the power grid as our batteries.

"A recent survey conducted by the Davis Energy Group found that 67 percent of recent homebuyers likely would have paid $8,000 more for their new house if it generated 40 percent of its own electricity. Another 26 percent said they would have considered it."

The fifty shingles on our garage are rated at 850 watts. That is, with the right temperature and humidity, the garage roof produces that many watts. With greater humidity, production can drop to 60 percent. On a cool, crisp day, the production figure might rise to 130 percent.

What does this cost? Roughly, about $15 per watt for an installation of this (small) size. Ouch! That’s nearly $13,000! Well, yes. But in 17 to 30 years that money will have come back to us. Such large numbers startle and frighten people until one figures the long-term savings in dollars for electric power. Further, as fuel costs rise, electricity prices will rise with them. As those increases bite, the payback time will be reduced considerably.

Photovoltaic power also has many agricultural applications:

  • Drying crops.
  • Heating space and water in livestock barns.
  • Heating greenhouses.
  • Remote applications, such as electric fencing, lighting, and water pumping, where such systems may be much cheaper than installing power lines and step-down transformers.

What will this installation do? At our house, we expect it to reduce the monthly electric bill somewhat. Since we are using the air conditioning a great deal at the same time that the solar shingles are being connected, the change in the bill might not be terribly obvious—but it is there. Were this group of shingles and the expensive inverter installed in a remote cabin, with no grid connection available, it could pump water out of a well, run a few lights, and keep a television and VCR running.

Finally, there is another gain: from the moment these shingles were connected, the air was a little bit cleaner. Not a change you would notice. But there is a tiny bit less pollution around because of this installation. We put up the shingles for the same reason someone drives a Prius: the mileage is good, but making the air cleaner is paramount.

Sunslates® : A Beautiful Way to Generate Electricity

Sunslates® are an advanced photovoltaic product. Sunslates® allow the roof of your home to serve as both a roof and a power plant simultaneously. A typical installation of 216 Sunslates® (about 300 square feet / 28 square meters) will cover from 60 to 80% of your power needs.

Alternate Energy Inc, as a stocking distributor of Sunslates, is qualified to install and service Sunslate brand Photoelectric products.

Frequently Asked Questions About SunSlates:
Q. Do I need to cover my entire roof with SUNSLATES?

A. It is not necessary to cover your entire roof with SUNSLATES. For a "standard" system of 216 SUNSLATES you will use about 300 square feet of space on your roof. The number of SUNSLATES that you will want to use depends on several factors that you can discuss with one of our employees.

Q. Does my roof need to be oriented in a certain direction?

A. As you may know, the best orientation for a SUNSLATES roof is due south. However a southwest or southeast roof will have a negligible reduction in power production (2-4%) and a due east or due west roof will see from 10 to 15% less power compared with a due south roof. Roof pitch is also a factor in power production, but it is not crucial. The difference in production between an ideally sloped roof and a regular 4/12 or 5/12 roof is usually no more than 5%.

Q. How does the system shed water?

A. The Sunslates use an overlapping system, much like a shake roof where there are two layers at any point on the roof. This is the way the system sheds water. Sunslates need at least a 4/12 (18 degree) roof pitch in order to shed water properly. Sunslates are based on a Swiss company known as Eternit. They produce the fiber cement slate that Sunslates are based on. The Swiss Eternit system is well known in Europe and has been used for around 60 years with great success. In Europe, this type of roofing is popular.

The New Alchemy Institute

From 1971 to 1991, the New Alchemy Institute conducted research and education on behalf of the planet :

"Among our major tasks is the creation of ecologically derived human support systems - renewable energy, agriculture aquaculture, housing and landscapes. The strategies we research emphasize a minimal reliance on fossil fuels and operate on a scale accessible to individuals, families and small groups. It is our belief that ecological and social transformations must take place at the lowest functional levels of society if humankind is to direct its course towards a greener, saner world."

"Our programs are geared to produce not riches, but rich and stable lives, independent of world fashion and the vagaries of international economics. The New Alchemists work at the lowest functional level of society on the premise that society, like the planet itself, can be no healthier than the components of which it is constructed. The urgency of our efforts is based on our belief that the industrial societies which now dominate the world are in the process of destroying it."

In the late sixties, as the world was waking to a need for Earth Day, a pioneering group founded a small non-profit research and education organization they called the New Alchemy Institute. Their aim was to explore the ways a safer and more sustainable world could be created. In the ensuing years, along with scientists, agriculturists, and a host of enthusiastic amateurs and friends, they set out to discover new ways that basic human needs--in the form of food, shelter, and energy--could be met. A Safe and Sustainable World is the story of that journey, as it was and as it continues to be.
The dynamics and the resilience of the living world were the Institute's model and the inspiration for their research. Central to their efforts then and now is, along with science, a spiritual quest for a more harmonious human role in our planet's future. The results of this work have now entered mainstream science through the emerging discipline of ecological design.
Nancy Jack Todd not only relates a fascinating journey from lofty ideals through the hard realities encountered in learning how to actually grow food, harness the energy of the sun and wind, and design green architecture. She also introduces us to some of the heroes and mentors who played a vital role in those efforts as well, from Buckminster Fuller to Margaret Mead. The early work of the Institute culminated in the design and building of two bioshelters--large greenhouse-like independent structures called Arks, that provided the setting for much of the research to follow.
Successfully proving through the Institute's designs and investigations that basic land sustainability is achievable, John Todd and the author founded a second non-profit research group, Ocean Arks International. Here they applied the New Alchemy's natural systems thinking to restoring polluted waters with the invention and implementation of biologically based living technologies called Ecomachines and Pond and Lake Restorers. A Safe and Sustainable World demonstrates what has and can be done--it also looks to what must be done to integrate human ingenuity and the four billion or so years of evolutionary intelligence of the natural world into healthy, decentralized, locally dreams hard won--and hope.
The Author NANCY JACK TODD is a writer and editor based on Cape Cod, where she gardens and swims and publishes the environmental journal Annals of Earth. Her other books, with John Todd, include Tomorrow is Our Permanent Address and From Eco-Cities to Living Machines. Her writings have also appeared in a number of publications and anthologies. She and John Todd have received the Bioneers Award, the Charles and Ann Morrow Lindbergh Award the Daimler/Chrysler award for design, the United Nations (FUNEP) Award, and the Swiss Threshold Award for contributions to human knowledge.

Stephanie Mills, author of Epicurean Simplicity:
Nancy jack Todd tells a marvelous story. This first-hand account of New Alchemy’s visionary, rigorous, and phenomenal projects to sustain life gives us all hope. This is a book that I’d like to share with local famers, sprawl fighters, and conscientious citizens. Here we have grounds for the hope of living simply, meeting our basic needs, and restoring health to the world, and on a shoestring budget.
Donald Watson, Architect:
a clear, inspirational story that shows the nitty-gritty of how talent coalesces around important issuses and how creative minds work together. This book is a necessary read for any idealist who aspires to change the world through architecture, design, the environment, and science.

Arizonal Sun Festival

Arizona Sun Festival

Can sponsor a heat wave event here in Harwich, showing the diversity of alternative energy by sponsoring a Solar weeklong summer seminar and festival?

HEATWAVE IN HARWICH

Sell little SUN badges like 1st Night in Chatham and have folks donate the $10, or $25. to replenish the Caleb Chase Fund for those seeking fuel relief this winter from our town. Teach-ins on how to convert from oil, gas, & electric to solar, passive solar, and other alternative energy and energy conservation modes. Connect the dots between war and oil. Conserve energy and save are children from a war for oil. Really support our troops, by keeping them home!

Get together with other folks and community of faiths, councils of churchs etc, and do Heat Wave 2006. This would be a bit like this idea from Arizona we perhaps could grow into if we found someone to head this up? Any ideas for anyone?

MILLSTONE, NJ — Imagine being able to see your meter running backward because you are generating your own power.







Jerry Sorgento believes the time has come for everyone to give solar energy a try.

The technology Sorgento uses allows for the sun to generate power during the daytime, when the meter will often run backward, and for the storage of that power so that it can be used during other times.

Though his company, New Age Solar, does sell solar panels, Sorgento is most proud of a newer generation product made by Sacramento-based Atlantis Energy Systems called Sunslates, which resemble ordinary slate roofing.

Solar energy roofing shines in Millstone
Businessman vows to save the planet through saving consumers money


Sorgento’s home in Millstone is the first in the state to use Sunslates.

“Nobody knows about Sunslates,” Sorgento said. “A lot of homeowners will not put solar panels on their roof because of aesthetics. Sunslates are for people who are more discerning about the look of their roof.”

Sorgento spent several years in the aerospace industry before leaving his job at Boeing in Seattle to take over his ill father’s horse farm in Manalapan. He worked on the farm for 12 years, he said, and is still a licensed Standardbred horse trainer.

When he tried to reenter his old industry in New Jersey, Sorgento discovered that “the aerospace industry left the area.”

In his mid 60s, he also felt that he was too old to be hired.

“When I sent in résumés saying I’d worked on the lunar landing program, they knew how old I was,” Sorgento said.

Sorgento started his company after taking a course about two years ago in solar energy.

“I got into it because I wanted to save the planet,” he said.

Sorgento believes that renewable energy sources are the wave of the future, and that relying on solar energy has a profoundly positive impact on the world.

“It’s cutting back on pollution, cutting back on our dependence on foreign oil, and cutting back on the oil barons taking so much money out of our economy,” he said.

According to the Department of Environmental Protection (DEP) Web site, about 82 percent of greenhouse gas emissions are from the burning fossil fuels that generate electricity and power our cars. The United States tops the charts at 6.6 tons of emissions per person per year.

The Web site further states that each person can affect about 32 percent of those pollutants “by the choices you make in three areas of your life.” The three areas are the waste that we produce, our personal transportation and “the electricity we use in our homes.”

The pollutants associated with burning fossil fuels, according to the site, have been shown to adversely affect our health, alter our ecosystems and change the climate.

We have known this for years, Sorgento said, but most people have not gone to solar or other alternative sources.

“I found that the public generally doesn’t seem to care about saving the planet, but what they were really interested in is saving money,” Sorgento said. “So in order for me to save the planet, I had to find a way to save them money.”

It’s an investment, he added, that is more affordable than ever thanks to state initiatives as part of the Clean Energy Program.

“What’s important to me is what this state is doing for the environment and [what it’s doing] to make [solar energy] affordable to the public,” Sorgento said. “New Jersey has the largest rebate program in the country.”

The state offers a flat rate rebate per DC watts of the system, which can save the consumer up to 70 percent, he said.

The buyer also qualifies for “green tags” that can be sold as a commodity to the utility companies.

Some companies that sell solar panels keep the green tags themselves, which is shortchanging the buyer, according to Sorgento.

“People need to understand the value of those green tags,” he stated. “You’re not just getting rid of your electric bill — you’re getting paid to do it. This is part of the payoff.”

The efficiency of the system depends partly on the pitch of the roof, and on how much of it is directly exposed to the sun.

Sorgento said that though in the thousands of dollars, the initial investment can be recouped in as little as five years, depending on other available incentives.

Having a home or business with little or no electric bill also adds value to the property.

Sorgento said businesses have the added advantage of getting an additional 10-percent, federal-tax rebate, and an accelerated depreciation on the product that will, in effect, give them all their money back within about five years.

This was enough to sell Tim Hundertpfund, the manager of Gaitway Farms in Manalapan, on the idea.

A few weeks ago, Sorgento installed solar panels on two of Hundertpfund’s barns, and there are plans in the works to do so for the remaining ones.

Hundertpfund said that he was skeptical at first because he knew little about solar power, but that he has known Sorgento through the horse business and trusted him enough to try it.

“I see a drastic change already,” Hundertpfund said. “During our peak hours, the meter would normally be running wild, but since it’s been installed, it slowed it right down to a crawl. And quite often, I go to it and it’s running backward.

“It looks as though it is producing as much or more than we’d anticipated,” he added.

Lance Miller, chief of staff for the New Jersey Board of Public Utilities (BPU), said that the state’s initiatives have produced great results in the areas of renewable energy.

“We’ve had a number of projects, and more and more are being constructed every day,” Miller said. “A lot of schools are looking at putting solar power on existing or new buildings.”

While the state is making strides, Sorgento is among those who fear the federal government is going in the wrong direction.

“Whether you are a Republican or a Democrat, you have to take notice that this state is a front runner,” he said. “We’re doing what the federal government should be doing.”

Miller agreed.

“We are pursuing energy efficiency standards for a variety of appliances,” Miller said, referring to the BPU. “The federal government has not developed these standards on a national level, so the states are stepping in to do that.

“The federal government has talked about weakening standards, and, for example, has lowered the energy efficiency requirement for air conditioners,” Miller continued. “It’s going in the wrong direction,”

Miller stressed the far-reaching effects of having regulations that make sense.

“Establishing the right energy policy can create jobs [and] provide for a thriving economy, and [it] also allows for a foreign policy that is liberated from energy dependence and provides increased security and a cleaner environment,” he said.

Sorgento said he hopes the state will continue its commitment by requiring a certain percentage of homes and businesses to use renewable energy sources. California has such a law, according to Sorgento.

“I’d like to see that here,” Sorgento said.

If we want a happy new year, then we must learn from Katrina lessons. We must be our own first responders. Their is an energy crisis and we can solve it together by getting it into our heads that the experts are us. We need not wait until corporations or governments see the light (solar light)! So here is my commitment for 2006. Find out about what it will take to Solaize and socialize the town of Harwich. Educate folks about the benefits of moving to solar for working folks.

Here is how we go about it!

Become An MSR Partner Want to become a Million Solar Roofs State or Local Partnership? Just send a letter to Glenn Strahs, DOE's MSR Coordinator, expressing your organization's commitment to MSRI objectives.

Be sure and describe the general nature of the partnership, its membership, and indicate its goal for the specific number of qualified solar energy systems to be installed on buildings within a specific community. At a minimum, partnerships must commit to installing 500 solar energy systems by 2010.

In addition, Partnerships are asked to develop a draft plan for meeting their installation goals under the Initiative. Partnerships are encouraged to base their plans for deployment on local values in relation to the technologies' unique applications and operational attributes.

Examples of activities the Partnerships may undertake as part of their plan include:

* Committing state and local government actions to overcome barriers to solar energy and energy efficiency applications in buildings;
