For many years scientists and engineers have been trying to provide low-cost solar energy by developing a cheap solar cell that is both highly efficient and at the same time simple to build, enabling it to be mass produced. Now, the team led by Empa researcher Ayodhya N. Tiwari has made a major leap forward: the researchers are presenting a new manufacturing technique for CIGS solar cells, in which tiny
Producing hot water using solar panels is standard practice. However, researchers from Madrid Universities Carlos III and Politecnica hypothesize that solar panels may be capable of providing large offices with both heat and air conditioning. The researchers intend to incorporate solar collectors into a gas-based cogeneration system with an absorption machine. This method will reduce energy expenditure and CO2 emissions if the project succeeds. This idea isn't wholly new.
Texas Parks and Wildlife Department Conservation of Natural Resources To conserve the usage of natural Texas resources, the Texas Parks and Wildlife Department (TWPD) recently installed 18 solar photovoltaic panel array systems across Texas. They range from a 5kW array thru 92kW array on the Austin Headquarters (Texas Solar Power Parks). The energy generated by these arrays typically supplies about 20% of facility power needs and supplements the Texas grid,
Costs presented to consumers are all relative to who is presenting them. Some contractors get a better price and install multiple units over higher effective units and some installers sell on the price but forgets to inform the consumer what they are really getting. Lets review the TRUE COST of the presented low-cost products over the SR1800 Solar Attic Fan. It has been reported to us and we have seen
One of the concerns that many people have about installing solar panels or solar attic fans is whether they will ever need to clean them. A recently released study by engineers at the University of California at San Diego, that can be found here, shows that even in the harshest, dusty climates with minimal rain, dust will only create a minimal effect on solar efficiency, and in almost all cases,
U.S. Secretary of the Interior Sally Jewell announced Tuesday the approval of three major renewable energy projects in Arizona and Nevada delivering up to 520 MW of renewable energy. What Are the Renewable Energy Projects? The three projects are the 350 MW Midland Solar Energy Project near Boulder City, Nevada, the 70 MW New York Canyon Geothermal Project, near Lovelock, Nevada, and the 100 MW Quartzsite Solar Energy Project, located

Electricity from Windows, more solar ventilation Cool studies showing more and more ways to implement solar to create energy. This would work by applying a thin layer of luminescent material windows. This layer would generate electricity by capture sunlight and guiding it to solar cells at the edges of the window. The film could generate 20 watts per square meter. About 4 square meters could power your computer as studies
Germany saves more on Solar Energy with their residential solar systems According to the Lawrence Berkeley National Laboratory, it costs about 62 cents a watt to build residential solar systems in Germany. In the U.S. that figure is $3.32 a watt, which is more than five times greater. SunPower Corp tells us the reason for this is installation time and more permitting requirements. Germany has about 32 gigawatts of installed
Each day the suns sends over 1,000 watts per square yard to the Earth's surface, but even as our technology continues to improve, current solar technology can only convert 20% of that to electrical power. Solar Energy improvements Physicists at the California Institute of Technology are working on designs that could raise that number to 50%. They hope to do this by absorbing more of the spectrum of light. These
