From: habshi on 1 May 2010 13:14 excerpt In 2000, 19,838 solar modules were shipped domestically. That number increased to 134,465 in 2005, and to 524,252 in 2008, the last year of available data. "People are eliminating their bills," deadpanned Minnick, who hosts tour groups at his father's eco-friendly home in Laurel every Saturday. "They're using the same money they spend every month on electric bills to install solar panels on their houses. And we're really going into the busy season, with installation of solar panels on houses." Sizes of solar energy systems (usually called pv systems, for photovoltaic) can vary; a residential system ranging from 3 kW to 8 kW can power a household, depending on the size of the house and how much power the house uses. Commercial systems, sometimes as big as the 40 kW system Green Logic is designing for Peconic Bay Wineries, are required to power larger operations

"The potential for this region is huge, with each square kilometre of land receiving every year an amount of solar energy that is equivalent to 1.5 million barrels of crude oil ."

Oil has little to nothing to do with electricity. You are still an idiot. -- Jim Pennino Remove .spam.sux to reply.

Now is the time to install solar panels. Pump the surplus power underground to be used later excerpt 1. Increased efficiency, production and lower cost. Solar panels are being produced quicker and cheaper than ever before. The cost of a photovoltaic panel has fallen from more than $6 a watt 30 years ago. Heck, prices even halved between mid-2008 and 2009. According to the Solar Energy Industries Association�s US Solar Industry Year in Review 2009, in 2009 photovoltaic module prices fell to �$1.85-$2.25 per watt from $3.50-$4.00 per watt in mid-2008.� Photovoltaic panels and other forms of solar power have also seen substantial gains in efficiency recently. While the average silicone-based photovoltaic cell converts about 12% of the sun�s energy into electricity, some silicone-based photovoltaic panels can now achieve 40% efficiency and their lightweight, relatively inexpensive counterparts, thin-film photovoltaics, aren�t far behind the average silicone photovoltaics. Solar installations for your home or business are smaller and more powerful and cheaper than ever before. The only thing that will make them more expensive is when demand outpaces production, something to think about as Solar Power demand ramps up in the next few years (Solarbuzz). After any financing is paid back you get free electricity! And if your system is set up for net metering, you can actually make money by feeding any extra electricity produced by your system back into the grid. Increase building value. Whether it�s a home or business, solar installations increase a building�s value.CNN Money reported in 2006 that zeroing out a home�s electric bill with a solar installation could increase the value of a home by up to $20,000. This might not appear to be as much as you first paid for the system, but when considering how much you saved in electricity bills while using the solar system and how much it added value to your home at sales time, it�s a sound investment. And the DOE in its publication, A Homebuilder�s Guide to Going Solar, says that �Solar homes sell at up to twice the rate of their conventional counterparts.� |
