As PV plants come out of warranty from the installer, an understanding of what needs repair, when, and how to do it is just as important as what equipment was selected and how it was installed.
Regenedyne has invented a magnetic levitation system, that when combined with the advanced aeronautics, eliminates the wobble issue and allows for a smooth, near frictionless, rotation.
Here are some of the more popular articles so far this year --- a wide range of alternative energy topics.
The PV pioneers and solar veterans made the future possible, but we couldn't imagine what it would look like. The young now own it, and they have no doubts about where it is going, and what they have to do to get it there.
Sun tracking is accomplished through azimuth and elevation (screw jack) drives that require a high degree of accuracy and durability.
The expected recovery in China, which accounts for more than 60 percent of global solar panel output, offers an early sign that manufacturers are succeeding in soaking up supply by building their own projects. The government’s push to promote developments closer to regions where electricity is needed most -- so-called distributed solar projects -- may also spur orders. Panel prices in China declined about 10 percent in the first six months of the year compared with the second half of last year, according to Bloomberg New Energy Finance. Higher tariffs imposed in the U.S. have had the opposite affect to what’s happened in China. Panel prices have increased about 15 percent since early June when the U.S. decided to apply preliminary duties on Chinese solar equipment imports, according to a global measure of panel prices. The U.S. Commerce Department acted again on July 25, proposing expanded penalties on some Chinese solar-energy imports in a victory for the U.S. unit of SolarWorld AG, which accused China of shifting production to Taiwan after it lost an earlier case.
China is the world’s largest producer of electricity, surpassing the United States in 2011, with demand increasing alongside its strong, sustained growth in GDP. Electricity generation in China has increased 9.6% annually, from 2005 to 2013, reaching 5,425.1TWh of electricity. Coal-fired plants currently make up over two-thirds of power generation, which is partly the result of an abundance of coal in China. Despite this growth, the country expects demand to continue to increase at a rapid pace, reaching 7.295TWh of demand in 2020 and 11,595TWh in 2040. However, the growth in electricity production from coal-fired plants has resulted in an increase in air pollution and general lack of efficiency. China is now moving aggressively to curb pollution and increase the supply of renewable power. The central government has prohibited new coal-fired plants to be built around Shanghai, Guangzhou and Beijing, which is currently in the midst of having all of its coal plants being converted to natural gas. Its 12th Five Year Plan, running through 2015, targeted non-fossil fuel energy to account for 15% of total energy consumption. One of the key industries expected to help meet these goals is wind power.
WASHINGTON, D.C. – In a significant ruling handed down today, a panel of judges at the World Trade Organization (WTO) accused the United States of violating global trade rules when it imposed punitive import duties in 2012 on many Chinese products, including solar panels. After the decision was announced, Rhone Resch, president and CEO of the Solar Energy Industries Association (SEIA), issued the following statement: "We are continuing to follow developments closely, but today's WTO decision is not expected to impact either the 2012 U.S. solar countervailing duty (CVD) order against China or any new CVD tied to the ongoing investigation until 2016, at the earliest. It's also important to remember that this decision is subject to an appeals process, which could take approximately 120 days. Assuming the decision is upheld on appeal, the United States would then have approximately one year to implement the decision. But even then, it's not clear whether the decision will result in any substantive modification of a solar CVD order against China."
Nokero's Next Generation Solar Light Bulb (the N182), Doubles Light Output, Decreases Costs and Lights the Way to Ending Extreme Energy Poverty
The three products we offer are the PowerChip, a silicon based fuel cell product targeted for defense and commercial customers, the second product is the BuzzBar Suite that is targeted at consumers for cell phone and tablet charging, and the final product is the Formira product, which is an air based fuel cell technology that generates hydrogen for formic acid and that can be used for larger power ranges.
Biomass is an important material for the sustainable source of energy. It can generate solid, liquid and gaseous products under different thermochemical conversion technologies. In this study, Melia dubia - a fastest growing energy crop was subjected to pyrolysis. Two products namely, biooil and char were produced and their characteristics were analyzed.
The equipment's power requirements can be met by the fuel cell system for 17 to 19 days without being refueled, and that window could be pushed to 21 days if a storm prevented access during the normal refueling window.
As a drop-in solution with Jet A/A-1 commercial aviation turbine fuel, this new Amyris-Total fuel can be seamlessly included in commercial aviation following the ASTM validation and amendment of the global standard.
Texas has more wind power generation than any other state, so it’s only fitting that Texas regulators are starting to ask some tough questions about wind power subsidies. The head of the state’s Public Utility Commission, Donna Nelson, is calling for a study to consider whether wind generators should start paying their share of transmission costs. Texas already invested $7 billion in high-capacity power lines that the state built to connect West Texas wind farms with the more populous cities in the east — such as Dallas and Houston. But wind power, as an intermittent resource, can create additional transmission costs, and those costs are borne by all the electricity customers in the deregulated market, which is about 85 percent of the state. Part of the study will determine the amount of the extra transmission costs and what, if any, remedy is needed, a PUC spokesman said. Wind power developers warn that making wind companies pay the same transmission rates as other generators will destroy Texas’ lead in wind power and undermine the economics of wind generation. Nelson, however, claims that giving wind companies a pass is no longer necessary because the industry has been around long enough to figure out its economics.
The Intersolar AWARD ceremony honored true innovators whose projects displayed the latest design and technology advancements in the solar industry. Three winners were named in the Solar Projects in North America category in front of a large crowd at the Innovation & Application Stage. They were judged on pioneering character, uniqueness, economic benefits, benefits for the environment and society, degree of technical innovation and proof of innovation. An independent committee of industry experts chose the Agua Caliente Solar Project by First Solar; the Whole Foods Solar Carport by Solaire Generation and the Alcatraz Island Micro-Grid by Princeton Power Systems. As a media partner AltEnergyMag.com will be covering Intersolar and bringing all the industry news and exciting new products to our eMagazine to help our readers make sense of the massive event.
