Solar Shingles Could Power Tomorrow's Homes

Posted June 21, 2007 10:13 AM

From LiveScience.com:

Tired of your roof just soaking up rays and not pulling its load? You're not alone. Increasing numbers of people are putting their roofs to work generating electricity. And that does not necessarily mean installing unsightly steel-and-glass solar energy modules. Today you can get photovoltaic shingles (or tile, or slate) that will do the job and still look like a roof. For instance, the National Institute of Standards and Technology has been testing various forms of photovoltaic roofing products for the past year on roofs in Maryland to calibrate their output. Brian Dougherty, project manager, said the test includes tile (popular in the Southwest), slate (popular in Europe) and shingle (popular everywhere). All of them have inactive areas where the roofer can drive nails and not short out any circuits.

By the time the building and electrical code developers have their say, you will have to run all of the connection wires in conduit and the cost will triple.

These shingles are actually very easy to install and, if you check with installers, you'll find the code isn't a barrier.

Also, contrary to the article, most solar electric systems being installed in California cover 70-80 percent of the homes electricity cost (not the other way around - ie, systems providing just 20-30 percent aren't the norm). Further, with the rebates and tax credits available, these systems provide a better return on investment than the historical stock market average over the past 30 years.

Cost-effective only because of tax-payer funding you say? The same can be said of conventional generation technologies and fuels which have also benefited from gigantic government assistance over the years and continue to run with government assistance even though they are "conventional, established" technologies.
