Being able to generate your own electricity from the comfort of your own home is something that is hitting the United States by Storm.

Back in March, Shelley Cohen and Mike Gala sent out a request to contractors to submit proposals on their project: to have solar panels installed on the roof of their colonial home in the District. Four companies responded, but one stood out: Astrum Solar.
“We were looking for the most comprehensive proposal and that’s what we found with Astrum,” said Cohen, a renewable energy project developer at Ameresco. “Astrum offered a full turnkey [approach]. They do the interconnection, the install and take care of the energy credits.”
Last week, Astrum Solar, which is based in Annapolis Junction, completed the installation of an 11.96 kilowatt system on the 1,100-square-foot roof of the couple’s home — the largest residential system in D.C. The company says the 52 photovoltaic panels should generate 13,754 kilowatt hours of electricity a year, meeting 75 to 85 percent of the home’s electricity needs.
The Cohen and Gala project is one of 500 installations Astrum has slated for completion this year, according to the company’s president, Vadim Polikov. “The solar market is incredibly vibrant and exciting,” he said. “The market, especially in the U.S., has probably tripled in size just about every year.”
About 72,939 photovoltaic systems have been installed in the United States in the past decade, according to the federal government’s Open PV Project. The Solar Energy Industries Association, a trade group, recorded a 37 percent increase in installations in 2009. Much of that expansion was attributed to an uptick in residential projects.
Since its inception in 2007, Astrum has primarily installed residential and small commercial solar panel systems. To meet demand, Astrum has in the past year doubled its office and warehouse space in Maryland and upped its employee roster to include more than 75 engineers, project managers, sales consultants and installers. Polikov declined to divulge the company’s earnings but said they have grown substantially year-over-year.
“It behooves installers, like Astrum Solar, to add value by being involved in all aspects of the sale,” said Eric Wesoff, an alternative energy analyst at GTM Research. “Next to purchasing the house, buying solar could be one of the largest expenditures for homeowners.”
Trading the value of their credits upfront shaved 25 percent off of Cohen and Gala’s installation bill. That deduction, coupled with a 30 percent federal tax credit and a District grant that covered another 35 percent, left the family with just 10 percent of the $65,000 bill.
All of the eight mid-Atlantic markets that Astrum operates in offer some form of tax incentives or rebates. Polikov said the District has the most generous incentives on the East Coast. With the cost of solar installation averaging $20,000 to $40,000 depending on roof size, inducements are crucial to expanding the domestic solar industry.
Stimulus funding, providing more than $271 million for solar energy investment, made it more cost-effective for homeowners to tap into the energy of the sun. Polikov credits the federal grants with the increase in business Astrum is seeing in states like Pennsylvania and Virginia. “We have ramped up a lot because of incentives,” Polikov said, noting that prior to the flow of federal dollars, the company was averaging a few hundred installations a year.
While the United States has become an important player in the global solar industry, it pales in comparison to European countries with markets that have extensive government incentives. Analysts estimate that the United States accounts for about a 15 percent market share, while Germany, the largest consumer of solar technology, averages 50 percent.
Wesoff expects those percentages to change as the cost of supplies declines and more U.S. state governments adopt programs like the enticement-laden California Solar Initiative. “It comes down to incentives and policy, or in some cases, renewable portfolio standards” that utilities must meet, he said.
Beyond government initiatives, Polikov believes customer referrals will help drive the solar market. Shelley Cohen certainly plans to advertise her solar roof. “You can live an urban eco-lifestyle and be as green as you want to be. The resources are there; the services are there,” she said. “We hope to set the example for people who are interested in” solar energy.
Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar energy technologies include solar heating, solar photovoltaics, solar thermal electricity and solar architecture, which can make considerable contributions to solving some of the most urgent problems the world now faces.
Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
In 2011, the International Energy Agency said that “the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countriesâ?T energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating climate change, and keep fossil fuel prices lower than otherwise. These advantages are global. Hence the additional costs of the incentives for early deployment should be considered learning investments; they must be wisely spent and need to be widely shared”.
A Gum Removal Buggy Makes It Easy.
Streets everywhere are full of chewing gum, cigarette butts, leaves, etc. However, most cities do not have a souped up golf cart that will not only take care of these items, it does it with a battery powered machine that utilizes solar energy that is harvested by a roof top mounted solar panel that will heat up the water to 170c before shooting the street with water, detergent and a vacuum.
This buggy removes the gum spots within 3 seconds and uses less than three liters of water an hour. Now, that could be utilized in many cities in America. Imagine how clean the streets could be with this little guy running around.
The buggy utilizes gasoline to run the generator and the steam unit. It only costs $30 per week. It would normally cost $35 per day to run the machine. Right now they only use the vehicle for four hours per day but sometimes more depending on how much gum is on the streets.
It is the brain child of Tennant, the Gum Removal Vehicle was sold to the Gold Coast City Council as well as councils in Brisbane, Mackay and Liverpool. It has recently exported one to Northern Ireland.
The GRV can:
vacuum up cigarette butts
sanitize water fountains
clean bins and street furniture
clean and sanitize toilet blocks
clean BBQ plates
clean glass windows
I think this is a great idea for any city in the world. It should certainly cut down on city maintenence cost.
