The Future of Solar Has Never Been Brighter
By Donna Avedon
Solar is definitely a strong buzzword these days, especially in the building and construction industry. As energy costs continue to rise, more homeowners are seeking alternative means to power their homes. Utilizing the sun's energy is one of the easiest ways to help save on energy costs while protecting the environment. Renewable energy from the sun offers a simple and productive method for producing power while lowering your utility costs.
In the past, the lack of aesthetics and high cost of installation had squelched solar conversions in many neighborhoods. Solar panels were perceived as an eyesore, both bulky and obvious. Until recently, the solar industry focused only on function not form. Now the industry is beginning to recognize aesthetics as an important factor in the residential market.
The roof's appearance was a non-issue for the Nature Conservancy's project in East Hampton. The architect hired the solar design professionals, Go Solar Inc., located in Riverhead, to install the hottest product in solar technology - Building Integrated Photovoltaic (BIPV). Go Solar, Inc. owner, Gary Minnick said, "A solar roof with this beautiful system blends well with most architectural styles."
BIPV is a system of photovoltaic laminates that are bonded to a metal roofing system with a wiring connection that sends direct electrical current to an inverter. The inverter converts this alternating electrical current to satisfy the structure's utility loads. The laminate used is a flexible, extremely lightweight self-adhesive material that is less than a quarter-inch thick and attaches easily to standing seam roof panels. This thin photovoltaic laminate captures energy from the sun and converts it to electricity throughout the day. In the average home - around 1,200 sq. ft. - the photovoltaic film usually generates all the energy the home requires. If the system supplies more electricity than the structure requires, solar energy will turn the utility meter backwards and reduce or eliminate the utility bill.
Minnick pointed out that the emergence of this attractive roof integrated product "has encouraged many more high-end home builders to incorporate solar systems into their projects." He said "solar cells are available in different colors, so there is no limitation for the architect or the designer." These modules have various degrees of translucency and can be used as filtered daylight sources, which works especially well for skylights and clerestory windows.
Another new emerging product is solar shingles, which resemble traditional asphalt roofing shingles, but are, in fact, photovoltaic in nature. If aesthetics are a big issue, solar shingles are for you. Available in a variety of styles and colors, they protect your home from the elements and converting sunlight into electricity. In addition, they're made of thin, flexible material, so they blend well with the architectural detail of your roof. Solar Shingles make a very attractive choice for new construction because they can be incorporated into the design right from the beginning.
Minnick pointed out that sales of all types of solar energy systems are on the rise due to dropping production costs and incredible rebate incentives. Here on Long Island, homeowners who invest in solar equipment can expect a pay-off in seven to nine years, depending on initial cost and installation techniques. Installing just a solar water heating system can save a family of four more than $670 a year on oil-gas bills.
Bill Anderson, a contractor from Center Moriches, considered solar powering his home in 2003, but at the time found the cost "prohibitive." When he looked into the installation again in the fall of 2006 he was pleasantly surprised. Anderson was sold on solar electricity when he realized rebates and tax incentives would reduce the cost of his 9.7-kilowatt system from $67,000 to $28,250. New York State offers tax credit up to 25% on installations, with the federal government kicking in up to 30%. Both New York State and Suffolk County wave any sales tax. Anderson received a rebate check for $39,000 from LIPA for his solar roof. With electrical rates certain to climb, he and his wife decided it was a wise investment.
"If enough people install solar panels it will have a tremendous impact on the environment," Anderson said. "You don't look at this only in terms of dollars and cents. We're trying to generate renewable power so we're not just burning fossil fuels." He added that selecting solar "is a no-brainer."
