New Map Shows Solar Jobs Still Growing Faster Than the Economy
05/16/13, Chris Meehan, SolarReviews
Thanks to The Solar Foundation (TSF), individuals can now learn more about the solar industry in their backyard, their neighboring states and across the country. On April 18, TSF introduced a new interactive map that showcases the nearly 120,000 jobs in America’s booming solar industry in 2012. This is the first time that the public can easily access the data on a state-by-state basis, and explore what parts of the solar industry are biggest—including manufacturing, installing, sales, project development and associated jobs.
Wind Industry in the USA
05/16/13, Jukka-Pekka Mäkinen, The Switch
The debate of the PTC just took too long and put the players to uncertainty. Installations were pushed in 2012 to record level of almost 13 GW. This year will be a big dip to estimated 4 GW or so and midterm the installations should level on 7 GW level.
Case Study: Thomonde Hospital In The Central Region of Haiti

The Thomonde battery bank was designed for 40 percent depth of discharge and only one day of autonomy due to the large loads of some of the medical equipment and the availability of the diesel generator.
Making the Switch: From Fixed to Solar Tracker
05/16/13, Rich Nicol, AllEarth Renewables
I compared the cost per watt to install a standard pole mount, such as a DPW, and found it cost the same as putting up a standard tracker. And of course by tracking you get the additional power.
Interview with Sophie Parker of The Nature Conservancy

In areas of the Mojave that are ecologically intact, renewable energy development poses a major problem for plants, animals, and other species. Some major issues include: habitat destruction and fragmentation, water use, and bird mortality.

This Printer Spits Out 10 Meters of Solar Panel Every Minute
Submitted on: 05/23/13, 01:49 PM
The printer system was developed by VICOSC, the Victorian Organic Solar Cell Consortium—a collaboration between the University of Melbourne, CSIRO Molecular and Health Technologies, and Monash University—and utilizes only existing printer technology to embed polymer solar cells (also known as organic or plastic solar cells) in thin sheets of plastic or steel at a rate of ten meters per minute. "We're using the same techniques that you would use if you were screen printing an image on to a T-Shirt," project coordinator and University of Melbourne researcher Dr David Jones said in a press release.
Organic solar cells rely on organic electronics, hydrocarbon molecules specifically, to generate a photovoltaic effect and convert the Sun's rays into usable DC current. The primary benefit to using organic cells is that these sheets can be printed in bulk for very little and the optical absorption coefficient of of the hydrocarbon molecules is so high that even small amounts of material can suck up a lot of light. On the other hand, organic cells are less efficient than their inorganic alternatives and tend to break down faster due to the chemical changes occurring within.
Currently, these organic sheets are able to produce up to 80W in the lab and between 10 and 50W under real world conditions. These cells aren't meant to replace conventional, inorganic panels, quite the opposite in fact. "The different types of cells capture light from different parts of the solar spectrum. So rather than being competing technologies, they are actually very complementary," said CSIRO materials scientist Dr Scott Watkins.
This printing technique could soon lead to buildings with PV laminated windows and exteriors and homes covered in solar shingles.

The Obama administration and the European Union have each decided to negotiate settlements with China in the world’s largest antidumping and antisubsidy trade cases involving China’s roughly $30 billion a year in solar panel shipments to the West, officials
A Down-To-Earth Wind Turbine
Submitted on: 05/20/13, 05:59 AM
The wind is faster at higher altitudes and wind power is directly proportional to wind velocity cubed. But mounting a turbine up high makes it more expensive to install and maintain, and requires a stronger tower to support such a top-heavy structure. Engineers at Shee
