“The Great Unknown”

‘2012 looks to be a year of healthy PV growth in North America, but many questions remain’

Photon magazine has predicted the outlook for PV capacity growth and decline for all U.S. states in a recent published article.

Tennessee appears to be one of the largest growth states for the year of 2012, with a predicted capacity of 55.0 MW to be added. In 2011, there was an estimated 18.0 MW installed in the state of Tennessee.

Most sections of the U.S. are showing steady growth for this year, except for most Midwestern states.

Refer to the January 2012 Photon magazine for more detailed information.

Solar panels to be installed at 11 Hawkins schools

The installation of energy efficient lighting at all Hawkins County schools, which was completed last month, is already beginning to show significant energy savings including more than $65,000 at three schools alone between May and December of last year.

But two more projects discussed by the Hawkins County Board of Education Thursday evening will drive down the system’s energy costs even further.

Those projects include the installation of solar panels at 11 Hawkins County schools by Morristown-based TerraShares, which will sell electricity back to the Tennessee Valley Authority.

Installation will be at no cost to the county, and the school system will receive a projected $70,000 per year in revenue from the electricity generated during the 10-year life of the contract.

Those 11 schools are Bulls Gap, Church Hill Elementary, Church Hill Intermediate, Hawkins Elementary, Joseph Rogers Primary, Keplar, McPheeters Bend, Mooresburg, Rogersville Middle, St. Clair and Surgoinsville Elementary.

DIY Solar Panels Made Out Of Grass Clippings

After years of tweaking by other scientists, researchers at MIT have figured out how to chemically stabilize plant-derived photosystem-I (PS-I), the structures inside plant cells that perform photosynthesis, on a substrate that creates electric current when exposed to light–all using readily available materials.
