New Jersey’s proposed energy policy calls for 22.5 percent  of the state’s power to come from renewable sources within 10 years  a goal that was the subject of heavy debate at a legislative hearing  attended by nearly 100 people Thursday.

Environmentalists said they want a 30 percent target, but business  leaders said that would drive their costs up.

State Sen. Jennifer Beck, R-Monmouth, defended the goal proposed  in Gov. Chris Christie’s draft energy master plan, calling it fair  and an “aggressive standard.”

Only eight states have higher renewable portfolio standards  than 22.5 percent, according to the U.S. Department of Energy website.  The standards are state policies that require electricity providers  to obtain a minimum percentage of their power from renewable energy  resources, including the sun and wind, by a certain date.

After Jeff Tittel of the New Jersey Sierra Club made a case for  the higher benchmark, Beck said: “I’ve been told on many occasions  that’s a stretch for us. We know solar and wind are great sources,  but they’re not particularly reliable, and that’s a challenge.  There’s also a responsibility for us to be realistic to set goals  that can be met.”

New Jersey currently obtains less than 10 percent of its electricity  supply from renewable energy sources.

But Tittel noted that New Jersey has ramped up, with more than  10,000 solar arrays installed. Only California has more.

“We’re No. 2 in solar installations. We shouldn’t go back,”  said Tittel, who added that he fears Christie’s policy could jeopardize  funding for renewable energy projects for homeowners and small  businesses and affect more than 200 solar companies in New Jersey.

Corporate executives who testified said the current relative  high costs of solar energy should not be discounted.

Michael Egenton, senior vice president of government relations  for the New Jersey Chamber of Commerce, said the poor economy underscores  the need for an energy policy that loosens restrictions. He praised  Christie’s plan.

“I think you have to look at everything in context,” said Egenton,  who said money spent on higher energy costs by companies would lead  to less money spent on operations and investments. “You have to  look at the bigger picture.”

The joint legislative hearing took place at the Toms River town  hall and was co-chaired by Sen. Bob Smith and Assemblyman John McKeon,  both Democrats.

State energy regulators also are holding hearings this month  and will vote to adopt a final energy policy later this year.

The lawmakers on the panel received an admonishment from Janet  Tauro, an environmentalist who is co-chairwoman of Grandmothers,  Mothers and More for Energy Safety.

With the topic turned to energy conservation, Tauro made a common  sense suggestion:

“We can turn down the air conditioning and turn off lights,”  said Tauro, also of the New Jersey Environmental Federation.

Most of the panel members were in jackets or sweaters.

There was little reaction from the panel after Tauro, a Brick  resident, made her comment. Later the room became colder, and more  lights were turned on.

Solar makes sense

May 31, 2011

As reported in Philadelphia Inquire May 30, 2011
With Pennsylvania
boasting the nation’s second largest number of solar-industry jobs, state
officials would be foolish to let the sun set on such a nascent but promising
industry. But that could happen due to a temporary mismatch between solar-energy
financing and market demand.

The construction of more than 4,000 solar projects has been a roaring
success, responsible for generating several thousand jobs at 600 solar
businesses. Growing that industry from scratch, with state and federal aid, also
boosted the use of nonpolluting and renewable energy. That will be particularly
helpful in meeting summer’s peak demand.

Yet, the boom in solar projects has outpaced the amount of solar energy
utilities are required to buy under the state’s alternative-energy rules. That
has depressed the value of solar-energy credits needed to provide a return on
photovoltaic solar systems, which have a steep, up-front price tag.

The best way for state officials to spur solar to new heights would be to
boost the modest solar-energy standard – now far lower than neighboring states,
at only 0.5 percent – by 2021. But last year, that idea ran into strong
opposition from Exelon and other utilities, coal producers, and business groups
– and a certain Republican candidate for governor.

Fortunately, a fellow Republican, State Rep. Chris Ross from Chester County,
unveiled a legislative proposal Tuesday that should be more to Gov. Corbett’s
liking. Ross would accelerate the amount of solar energy utilities are required
to purchase for the next few years, but leave the overall standard at just 0.5
percent. He would also follow other states by barring out-of-state solar
producers contributing to the solar glut in Pennsylvania.

The Ross proposal amounts to a tweak, but one that could be critical to
maintaining the state’s foothold in solar energy. Corbett and Republican
legislative leaders could fall back on tea-party ideological antagonism toward
so-called government mandates – or they could prove themselves progressive
enough to embrace a modest plan that makes sense for the state’s 21st-century
economy.

The California-based solar leasing firm Sungevity announced a deal on Monday with home improvement giant Lowe’s that could make obtaining a personalized estimate for installing solar panels a push-button affair at Lowe’s outlets.

The deal gives Lowe’s just under a 20 percent stake in Sungevity, according to a solar industry source, though neither company would discuss specific dollar figures.

Under the agreement, scheduled to launch in 30 Lowe’s stores in California in July, customers will be able to access kiosks equipped with Sugevity’s iQuote system, a Web-based application that allows homeowners to simply enter their address and receive a firm installation estimate within 24 hours, eliminating the expense of an on-site visit.

The system combines aerial and satellite image analysis with research by Sungevity engineers at the company’s Oakland headquarters to assess the geometry of a home’s rooftop, its disposition to the sun at different times of day and year and any potential occlusions presented by nearby vegetation or built objects.

In addition to an installation estimate, customers can also get a visual rendering of their home with solar panels installed. And if interested parties provide information on typical power usage, such as an account number or past electric bills, the iQuote system can estimate potential savings expected from using the equipment.

The iQuote system can already be used online, and the company’s founder, Danny Kennedy, estimated that roughly 25,000 users had taken it for a test drive, though only about 1,500 of those had been converted to sales.

The deal with Lowe’s, Kennedy said, could help Sungevity — a petite player in the solar leasing market compared to bigger players like SolarCity of San Mateo, Calif., or San Francisco-based SunRun, which raised $200 million in financing earlier this month — significantly expand its reach.

“This will help us to get in front of thousands more customers, in front of middle America,” Kennedy told The Huffington Post. “We’ll be taking it to the ‘burbs, as it were.”

Despite tough economic times and often uncertain economic incentives, a number of analyses predict a boom year for solar power in 2011.

A report published in December by IDC Energy Insights, a market research firm based in Framingham, Mass., estimated following a healthy 2010, the solar market in North America could well see two gigawatts of solar power installations this year.

Jay Holman, the report’s lead analyst, told The Huffington Post that those numbers had been revised somewhat, but that 2011 was still expected to bring in 1.6 gigawatts of new solar installations, roughly double the 2010 total.

Part of the reason for America’s interest in solar energy may be a decline in the robust incentives the once drew a deluge of equipment and installations to the European market, particularly countries like Germany, the Czech Republic and Italy, Holman said. Those countries have begun to scale back their subsidies, forcing companies to look to other markets.

Meanwhile, federal tax incentives, including a 30 percent tax cash grant extended through the end of 2011, have helped keep solar alive. Several states have healthy incentives in place as well, including the eight states where the Sungevity/Lowes deal will eventually be rolled out: Arizona, California, Colorado, Delaware, Maryland, Massachusetts, New Jersey and New York.

Holman also said solar leasing companies like Sungevity, SunRun and Solar City, which retain ownership of the equipment while reducing or, in many cases, eliminating the up-front installation costs, also help drive the expansion of solar power.

“Obviously, we’re obsessed with being customer-focused,” said Kennedy. “We hope that this deal will make going solar as easy as shopping for light bulbs.”

SOUTH PHILADELPHIA – November 18, 2010 (WPVI) — When you think of the Eagles you think GREEN – and we’re not just talking about the

The Eagles organization has long been committed to the environment and energy sustainability. Well, today the Eagles will take a bold move when they make Lincoln Financial Field the first major sports stadium in the world to generate its own electricity.

In the coming months the Linc will be outfitted with approximately eighty 20-foot tall spiral shaped wind turbines on the top rim of the stadium and 2,500 solar panels on the façade. Along with the state of the art power system, energy will be generated on-site.

The project will cost an estimated $30-million, but the Eagles expect to save an estimated $60-million in energy costs in the coming years.

The stadium will generate enough electricity to power 26,000 homes – far more than needed to power the stadium. So, the Eagles will be selling excess electricity back to the local power grid.

Two hundred people are expected to be employed to design and install the system. Six hundred more jobs are expected to be created because the Eagles are committed to using people from the local community through contractors and vendors.

More information on the project is scheduled to be released later today at Lincoln Financial Field by Eagles owner Jeffrey Lurie, Philadelphia Mayor Michael Nutter and NFL Commissioner Roger Goodell.

Where’s The Bottom

November 12, 2010

Natural gas prices continue being very competitive. 

How low will they go? 

Hurricane season does not officially end until November 30th, however it is rare to see a tropical storm in the Gulf this late in the season. The 2010 Atlantic Hurricane season was very active this year, with 19 named storms. The last time I looked we were up to T for Toma. 

Here we are heading into the end of November and natural gas nymex prices are still under $4.00. 

Where is the bottom? 

Without a crystal ball, this ends up being a very difficult question to answer. 

When you look at the overall picture not much has changed, Storage levels are still at a 5-year high and holding. It has been like that for several years now.

 We do have the Marcellus gas in Western PA. Some geologists estimate that it could yield enough gas to supply the entire East Coast for 50 years.

 That must prove to be the major factor. It is the old supply demand scenario?

The bottom line states, that if your business is currently spending a minimum of $3000 a month and you are still with the local provider, you should be looking at buying natural gas from a 3rd party provider in the deregulated market.

Did you know that if you are a PSEG customer, you ended up paying 15% higher for natural gas over the last year?

How much savings would that have equated for your company?

With natural gas prices being so low we have also seen this translate into very competitive deregulated electric prices. We recently signed a client the other day and they will be saving 30% on their electric supply cost for the next 2 years.

I know that savings is a parity of how much you spend but let me ask again.

How much savings would that have equated for your company?

If you are currently spending over $3000 a month on electric and your company is still with the local provider, you should be looking at buying electric from a 3rd party provider in the deregulated market.

The Garden State’s status as a solar-energy leader will get a major boost Wednesday, when officials break ground on what will be the largest solar energy farm in the Northeast.

Con Edison Development, a subsidiary of Consolidated Edison Inc., and Texas-based Panda Power Funds plan to build a 20-megawatt solar farm on a 100-acre site in Pilesgrove. The installation, expected to go online in May 2011, will feature 71,400 solar panels and cost between $85 million and $90 million.

Con Edison Development and Panda announced their intent to partner on solar projects in April.

Steve Tessum, vice president of east region management at Panda and manager of the Pilesgrove project, said South Jersey was chosen as the site in part because of the state’s support of solar energy.

“We did look at other states,” Tessum said. “Quite frankly, the regulatory climate in New Jersey is friendly to somebody who wants to own and develop a solar-power utility.”

The farm will be connected directly to the electrical grid via the Atlantic City Electric distribution system, said Mark Noyes, vice president of Con Edison Development.

Noyes said the arrangement with Panda is a 50-50 partnership: Panda is taking the lead in development, Con Edison will take the lead in operations and energy management, and construction will be split.

“The reason it makes sense to partner with Panda is, much like our background, they’re developers and they know how to develop projects, whether natural gas and oil, wind, solar,” Noyes said. “The development expertise is really what drives the development.”

Noyes said the property had originally been slated for the development of 67 homes, each with its own septic tank.

“The town opposed that type of taxing, from an environmental and economic standpoint,” Noyes said. “The construction of those homes never got through the planning board, so we were able to go in and acquire that land from the local player for this solar farm.”

Tessum said the solar farm doesn’t require any municipal infrastructure development, as the housing plot would have.

Con Edison Development said the installation is expected to generate enough electricity to power 5,100 homes.

Obama Health Care

March 5, 2010

WASHINGTON — The end game at hand, President Barack Obama took command Wednesday of one final attempt by Democrats to enact bitterly contested health care legislation, calling for an “up or down vote” within weeks under rules denying Republicans the ability to kill the bill with mere talk. Appearing before a White House audience of invited guests, many of them wearing white medical coats, Obama firmly rejected calls from Republicans to draft new legislation from scratch. “I don’t see how another year of negotiations would help. Moreover, the insurance companies aren’t starting over,” the president said, referring to a recent round of announced premium increases affecting millions who purchase individual coverage.

While Obama said he wanted action within a few weeks, Senate Majority Leader Harry Reid, D-Nev., seemed to hint a final outcome could take far longer. “We remain committed to this effort and we’ll use every option available to deliver meaningful reform this year,” he said.

 The results will affect nearly every American, mandating major changes in the ways they receive and pay for health care or leaving in place current systems that leave tens of millions with no coverage and many others dissatisfied with what they do get.

With Republicans united in opposition, there is no certainty about the outcome in Congress – or even that Democrats will go along with changes Obama urged on Wednesday in what he described as a bipartisan gesture. With polls showing voters unhappy and Democrats worried about this fall’s elections, Obama also sought to cast the coming showdown in terms larger than health care, which is an enormously ambitious undertaking in its own right. “At stake right now is not just our ability to solve this problem, but our ability to solve any problem,” he said.

Republicans dug in for another struggle on an issue that they agreed would echo into the fall campaign. The Senate GOP leader, Mitch McConnell of Kentucky, said a decision by Democrats to invoke rules that bar filibusters would be “met with outrage” by the public. “This is really not an argument between Democrats and Republicans. It’s an argument between Democrats and the American people,” he said. At its core, the legislation under discussion still is largely along the lines Obama has long sought and GOP critics attack as a government takeover of health care. It would extend coverage care to tens of millions of uninsured Americans while cracking down on insurance company practices such as denying policies on the basis of a pre-existing medical conditions. A new “insurance exchange” would be created in which private companies could sell policies to consumers under terms fixed by the federal government.

Much of the cost of the legislation, nearly $1 trillion over a decade, would be financed by cuts in future Medicare payments to hospitals and other providers and higher payroll taxes on individuals earning more than $200,000 and couples over $250,000.

 Story continues below The president’s appearance marked a presumably final pivot point in a long, uphill effort by Obama and other Democrats to enact far-reaching changes to the health care system – and with his own administration at an important crossroads. Eager to turn attention to efforts to stimulate the economy and create jobs, the president is seeking a victory on health care that can also give him a boost on other priority legislation. At the same time, a defeat could damage Obama’s ability to help fellow Democrats heading into the fall campaign. Failure on health care could well lead to a shake-up of the president’s White House team, which has received criticism recently from Democratic lawmakers.

After nearly a year of struggle, the House and Senate passed separate bills late last year, and appeared on course for approving a final compromise version early in 2010. But those efforts were abruptly abandoned when Republicans unexpectedly won a special election in Massachusetts. Sen. Scott Brown’s victory gave the GOP an ability they had lacked, the strength to sustain a filibuster, a form of opposition that requires supporters of a bill to post 60 Senate votes in order to cut off debate and force a final decision.

 Democrats went into something of a political fetal position, and have begun to stir in recent days only as Obama asserted his determination with a bipartisan summit followed by a revised set of proposals.

Obama said the use of rules that deny the minority the right to a filibuster had been used numerous times in recent years, including on passage of welfare reform legislation in the 1990s and twice when President George W. Bush pushed tax cuts to passage. Health care “deserves the same kind of up or down vote” as those earlier measures, he said.

 Under the rather complicated approach under discussion, the House would be asked to approve the bill that passed the Senate late last year, despite objections by many members of the rank and file to several provisions. Simultaneously, both houses would also vote for a companion measure whose purpose would be to make changes in the first bill sought by either House Democrats or the White House.

Obama said he was exploring GOP proposals for cracking down on fraudulent medical charges, revamping ways to resolve malpractice disputes, boosting doctors’ Medicaid reimbursements and offering tax incentives to curb unnecessary patient visits to doctors. The ideas include an experiment that would establish special courts in which judges with medical expertise would decide malpractice allegations. The idea has been criticized by the Center for Justice & Democracy, a consumer group that prefers the current system of awarding damages. It said health courts would be “anti-patient.”

The White House and Democratic leaders said they hoped that Obama’s maneuvering would at least win the votes of wavering conservative and moderates in their own party, even if it didn’t entice Republicans. But there was no guarantee of success, despite Obama’s vow to do everything in his power to succeed – and a White House announcement that he would travel to Pennsylvania and Missouri next week to campaign for the legislation.

It’s a bird, it’s a plane — it’s a solar panel?
Residents of many local towns may have recently noticed panels being installed about 15 feet up on residential utility and street-light poles. The panels are five feet by two and half feet, and weigh about 60 pounds. By the end of 2013, 200,000 panels will have been installed throughout New Jersey.

PSE&G sources say that their “investment is the largest pole-attached solar installation in the world … New Jersey has more installed solar capacity than any state except California.” New Jersey estimates its solar power capacity at 40 megawatts of “pole-mounted solar.” Karen Johnson, media spokesperson for the company, estimates one megawatt as enough energy to power approximately 800 homes.
The work is part of a renewable energy program approved for PSE&G by federal regulators last July. It is called Solar 4 All, and is estimated to be a $515 million investment on the part of PSE&G in New Jersey over the next three years. The goal of the program is to move the state closer to meeting an energy master plan requirement of 4.4% (or 80 megawatts) of solar energy use in the electric grid by 2020.
PSE&G says, “The installations will be paid for by PSE&G electric customers. The first year bill impact for the average residential customer will be roughly 10 cents a month.”
Currently, panels are being placed on pre-selected PSE&G-owned utility and street light poles only. Negotiations to share space with Verizon-owned poles are planned.
According to the PSE&G fact sheet on the installation (available at http://www.PSEG.com), poles that qualify for the panel meet several criteria, besides being owned by the utility company. PSE&G is selecting poles that can support the units, face in a southerly direction and have no more than one transformer already on the pole.
The Retrospect caught up with two contracted installers from Riggs Distler and Company, Inc. this week, while they installed a new panel on a pole on Haddon Avenue. Derwin Booker said that the project is keeping his union, and the contractor he works for, busy. While he has been working on installs in Collingswood and Haddon Township, he also worked on the recent installs along Kings Highway in Cherry Hill.
All of the panels are equipped with GPS (Global Positioning Satellite receivers), and each faces exactly 193 degrees south-southwest in order to maximize solar power collection, explained Booker. He said that specific poles were selected from the millions of utility and street poles throughout New Jersey. The panels are equipped with what he called an aggregator, which communicates the collection rates of 10 to 15 panels at a time, back to a main data collection site, so that the rate of energy per cluster of panels can be measured and tracked.
All of the solar energy collected by the panels flows back into the electronic grid as power. Booker commented that the additional energy generated can help in heavy electrical use periods – like summertime, when air conditioners are running — when service is at risk of brown-outs.
Additionally, PSE&G explains, “The installations will generate Solar Renewable Energy Certificates (SRECs). PSE&G will sell any SRECs it generates to offset program costs. PSE&G will sell the power into the PJM (Pennsylvania-Jersey-Maryland) wholesale grid and will receive federal tax credits – which will also be used to offset the cost to customers.”

As reported in Courier Post

DURANGO, COLO. — The sun had just crested the distant ridge of the Rocky Mountains, but already it was producing enough power for the electric meter on the side of the Smiley Building to spin backward.

For the Shaw brothers, who converted the downtown arts building and community center into a miniature solar power plant two years ago, each reverse rotation subtracts from their monthly electric bill. It also means the building at that moment is producing more electricity from the sun than it needs.

 “Backward is good,” said John Shaw, who now runs Shaw Solar and Energy Conservation, a local solar installation company.

 Good for whom? 

As La Plata County in southwestern Colorado looks to shift to cleaner sources of energy, solar is becoming the power source of choice even though it still produces only a small fraction of the region’s electricity. It’s being nudged along by tax credits and rebates, a growing concern about the gases heating up the planet, and the region’s plentiful sunshine.

 The natural gas industry, which produces more gas here than nearly every other county in Colorado, has been relegated to the shadows.

 Tougher state environmental regulations and lower natural gas prices have slowed many new drilling permits. As a result, production — and the jobs that come with it — have leveled off.

With the county and city drawing up plans to reduce the emissions blamed for global warming and Congress weighing the first mandatory limits, the industry once again finds itself on the losing side of the debate.

 A recent greenhouse-gas inventory of La Plata County found that the thousands of natural gas pumps and processing plants dotting the landscape are the single largest source of heat-trapping pollution locally.

 That has the industry bracing for a hit on two fronts if federal legislation passes.

 First, it will have to reduce emissions from its production equipment to meet pollution limits, which will drive up costs. Second, as the county’s largest consumer of electricity, gas companies probably will see energy bills rise as the local power cooperative is forced to cut gases released from its coal-fired power plants or purchase credits from other companies that reduce emissions.

“Being able to put solar systems on homes is great, you take something off the grid, it is as good as conserving,” said Christi Zeller, the executive director of the La Plata Energy Council, a trade group representing about two dozen companies that produce the methane gas trapped within coal buried underground.

“But the reality is we still need natural gas, so embrace our industry like you are embracing wind, solar and the renewables,” she said.

It’s a refrain echoed on the national level, where the industry, displeased with the climate bill passed by the House this summer, is trying to raise its profile as the Senate works on its version of the legislation.

In March, about two dozen of the largest independent gas producers started America’s Natural Gas Alliance. In ads in major publications in 32 states, the group has pressed the case that natural gas is a cleaner-burning alternative to coal and can help bridge the transition from fossil fuels to pollution-free sources such as wind and solar.

 “Every industry thinks every other industry is getting all the breaks. All of us are concerned that we are not getting any consideration at all from people claiming they are trying to reduce the carbon footprint,” said Bob Zahradnik, the operating director for the Southern Ute tribe’s business arm, which includes the tribes’ gas and oil production companies. None is in the alliance.

 Politicians from energy-diverse states such as Colorado are trying to avoid getting caught in the middle. They’re working to make sure that the final bill doesn’t favor some types of energy produced back home over others.

 At a town hall meeting in Durango in late August, Sen. Mark Udall, who described himself as one of the biggest proponents of renewable energy, assured the crowd that natural gas wouldn’t be forgotten.

“Renewables are our future — but we also need to continue to invest in natural gas,” said Udall, D-Colo.

 Much more than energy is at stake. Local and state governments across the country also depend on taxes paid by natural gas companies to fund schools, repair roads and pay other bills.

In La Plata County alone, the industry is responsible for hundreds of jobs and pays for more than half of the property taxes. In addition, about 6,000 residents who own the mineral rights beneath their property get a monthly royalty check from the companies harvesting oil and gas.

 “Solar cannot do that. Wind cannot do that,” said Zeller, whose mother is one of the royalty recipients. In July, she received a check for $458.92, far less than the $1,787.30 she was paid the same month last year, when natural gas prices were much higher.

 Solar, by contrast, costs money.

Earlier this year, the city of Durango scaled back the amount of green power it was purchasing from the local electric cooperative because of the price. The additional $65,000 it was paying for power helped the cooperative, which is largely reliant on coal, to invest in solar power and other renewables.

 “It is a premium. It is an additional cost,” said Greg Caton, the assistant city manager.

Instead, the city decided to use the money to develop its own solar projects at its water treatment plant and public swimming pool. The effort will reduce the amount of power it gets from sources that contribute to global warming and make the city eligible for a $3,000 rebate from the La Plata Electric Association.

Yes, the power company will pay the city to use less of its power. That’s because the solar will count toward a state mandate to boost renewable energy production.

“In the typical business model, it doesn’t work,” said Greg Munro, the cooperative’s executive director. “Why would I give rebates to somebody buying someone else’s shoes?”

The same upfront costs have prevented homeowners from jumping on the solar bandwagon despite the tax credits, rebates and lower electricity bills.

 Most of Shaw’s customers can’t afford to install enough solar to cover 100 percent of their homes’ electricity needs, which is one reason why solar supplies just a fraction of the power the county needs.

 The higher fossil-fuel prices that could come with climate legislation would make it more competitive.

 “You can’t drive an industry on people doing the right thing. The best thing for this country is if gas were $10 a gallon,” said Shaw, as he watched two of his three full-time workers install the last solar panels on a barn outside town.

 The private residence, nestled in a remote canyon, probably will produce more power from the sun than it will use, causing its meter to spin in reverse like the Smiley Building’s. The cost, however, is steep: more than $500,000.

As reported in Green Inc.

The price of rooftop solar panels has fallen drastically, as I reported in The New York Times on Thursday. But for some homeowners, the upfront costs remain prohibitive.

Indeed, many readers have remarked on the article’s opening anecdote, about a homeowner in the Houston area who installed a 64-panel, $77,000 system (before the 30 percent federal tax credit) for his amply sized house and garage.

One way to bring the initial costs down would be to put smaller arrays on homes. After all, if financial constraints are a consideration, why put dozens of panels on your home when you could put just one or two?

One reason has long been the inverter — the piece of a solar-power system that converts the direct current voltage produced by the panels to accelerating alternating current, which runs through the home. Right now, according to Glenn Harris, the chief executive of the consulting firm SunCentric, it is hard to find an inverter small enough to handle just one solar panel.

But microinverters — which fit on a single panel — are on their way.

Enphase Energy, a company based in California, has shipped 50,000 microinverters since last August, according to Raghu Belur, one of the company’s founders. Each costs about $200, and can be paired with a single solar panel and popped on the roof.

(Single solar panels, producing on the order of 200 watts, can be had for less than $1,000 — though that won’t do much to augment most household power needs.)

 “It is the key to enabling what’s called do-it-yourself-ers,” said Mr. Belur, though he says that it is wise to hire a licensed electrician to make the final connection. (Enphase says that its microinverters do eliminate high-voltage direct current, so there is less danger of a nasty electric shock.)

 “We’re specifying Enphase microinverters in our residential designs more and more often,” said Ryan Hunter, of the Texas installer Meridian Solar, in an e-mail message. The Enphase systems allow for greater flexibility, he said, and are “more shade tolerant in limited spaces.”

 Enphase officials say that having an inverter on each panel increases the efficiency of the solar array. On traditional systems, lower output from one panel — because of dust or leaves accumulating, for example — can affect the performance of every panel in the set. But the microinverters preserve the independence of each panel, so that the panels do not revert to the lowest common denominator of output.

Right now, Enphase microinverters do not come attached to panels. But by the middle of next year, big-box stores, Mr. Harris of SuncCentric predicted, will be stocking solar panels with the microinverters strapped on.

“The real magic is you don’t have to spend $20,000 to $30,000 to get a solar system,” he said.
