Largest Manhattan Solar Array Completed

January 24th, 2012 | by Joshua S Hill

Deutsche Bank announced Monday the completion and operation of it new 122.4kW solar photovoltaic system installed atop its Americas headquarters at 60 Wall Street, New York. The array is expected to decrease carbon emissions by 100 metric tonnes per year

Chicago Skyscraper to Generate Solar Electricity

March 24th, 2011 | by Glenn Meyers

In an experimental program, Chicago’s tallest building, Willis Tower (previously the Sears Tower) will soon feature high power density photovoltaic glass units (PVGUs) on the south side of the 56th floor

No Money Down Solar

August 6th, 2007 | by Philip Proefrock

That's an intriguing lede to an article. Many of you may be suspicious that I'm going to be talking about CitizenRE and their alleged "free solar energy" offer, but this isn't about that program. (And if you aren't familiar with CitizenRE, I recommend that you take a look at the three-part series from Mike Taylor that discusses the program starting here.) Instead, I'm refering to an intriguing point that is made in an article titled "10 MORE Things to Know Before Buying a Solar Electric System" by Bruce Karney from It's not a get-rich-quick scheme, but rather a simple fact of finance for people in regions where they are currently paying high rates for their electricity. If you are paying more than 20 cents per kilowatt hour, this may be applicable to you.

The article skips many of the basic things that many people considering solar are already well aware of, such as that a solar PV system needs to be installed on a south or southwest facing (for installations in the northern hemisphere); those are covered in his preceeding article. Both articles provide good information, and are highly recommended reading, especially if you are seriously considering buying a solar PV system.

However, the most intriguing item to me in the article was the line "You can buy a solar system for no money down." For many homeowners with concerns about the costs and cash flow, PV panels are seen as a pricey addition that they just can't afford to pay for right now. But that's not necessarily the case. As Karney explains,

Weekend Review: The Renewable Energy Handbook and Smart Power

May 19th, 2007 | by Philip Proefrock

William H. Kemp, The Renewable Energy Handbook (2005) and $mart Power (2004): Aztext Press

Wiliam Kemp has written two books on renewable power and off-grid systems for homes, $mart Power (2004) and The Renewable Energy Handbook (2005). (Smart Power actually uses a dollar sign for the S in the title.) These two books are largely a first and second edition of the same text, with the second edition being expanded with several new chapters and additional information.

Both of Kemp's books are comprehensive volumes. He addresses a range of alternate power generating options. There are chapters on photovoltaic (PV), wind, biomass, and micro hydro. More than just discussing the technical aspects of the generating systems, he also covers efficiency, interconection, "Heating and Cooling with Renewable Energy," "Living with Renewable Energy," and the other issues surrounding having a home with renewable systems. He also has a section about making biodiesel and another section about eco-pools (naturally-, rather than chemically-filtered swimming pool systems) and solar heated pools and hot tubs.

The Renewable Energy Handbook and $mart Power both go into some depth about renewable energy systems. Kemp shows all aspects of the various systems, dealing with hardware installation, electrical connection, and the range of what is necessary to install any of the systems he discusses. While I would not rely solely on these books for direction about installing a PV system or a wind turbine, it does provide a greater depth of information. A homeowner can get a better sense of the scope of work required for installing a renewable system, and have a better idea about what is involved, and whether or not it is something they want to take on.
