There is a wide range of utility experiences, but about 70% of solar activity is concentrated in the top 10 utilities as measured by our annual survey (www.sepatop10.org). The top 50 utilities encompass greater than 95% of the solar.
Seven of the top 17 states with the most rapid growth in the clean tech sector are considered swing states for the 2012 presidential election. Numbers like these suggest we are entering an era in which politicians who unfairly criticize or otherwise ignore clean tech run the risk of alienating a bedrock constituency: job holders, most of whom vote. We all need to understand that green jobs and clean tech are not merely the idle dreaming of a small group of partisan activists and insiders, but a source of livelihood for millions of Americans, literally in all parts of the country. What's more, their numbers are growing every day.
Peak oil? coal? gas? tar sands? shale gas? or any such? New discoveries seem to outpace all fears of early shortages. CO2 and AGW worries groundless? The jury is still out on that. Does that mean we can live free of any worries and carry on without any further need for doomsayers and troglodytes? Well yes, based on such questions. But could it just be possible that these are not the right questions to ask as they might produce wrong answers and consequently lead to wrong policies and investments?
The ASES National Solar Tour is the world's largest grassroots solar event. More than 160,000 participants will visit some 5,500 buildings in 3,200 communities across the U.S.
Solar Power International (SPI) is North America’s premier business-to-business event for professionals in solar energy and related fields. Thousands of solar energy industry professionals from 100+ countries attend. One of five attendees comes from outside the United States. More than 900 exhibiting companies from all vertical markets in the solar power spectrum. AltEnergyMag.com has put together a special newspage devoted specifically to news and announcements coming out of this years show . We invite those exhibitors to post PR directly to this newspage here.
The significance of Solar Power International comes not from the number or diversity of its attendees. Rather, this year's conference matters because it comes at a time of rapid innovation and change in the industry. These changes affect so many aspects of the business that players need to constantly update their understanding; to be just a month behind puts you at a competitive disadvantage. What's changed since Dallas? SPI 2011 was held last October in Dallas, Texas. Since that time, the industry landscape has changed drastically, specifically with regard to how projects are getting financed. In any given month, DG Energy Partners sees dozens of MWs of projects seeking financial partners. Regardless of where these projects are located, the underlying trends remain the same; hardware prices have continued to fall, EPC margins have continued to shrink and projects have grown increasingly difficult to complete. And we haven't even mentioned what changes we can expect in 2013.
Chinese solar companies expect the European Commission to announce within days a formal investigation into their alleged dumping of solar panels in Europe, which could result in heavy tariffs being imposed on them next year. The expected move against the companies, whose share prices have tumbled and whose financial outlook is cloudy due to oversupply and falling solar-equipment prices, would come as they are already fighting clean-energy trade battles on several fronts. Also, China and the European Union are at loggerheads over several other trade rows, including a European plan to punish airlines if they don't comply with an emissions-control program—issues that could have the potential to sour China's readiness to help in financially underpinning Europe's debt-laden economies. European solar-panel makers filed a confidential complaint July 25 with the commission, the EU's executive arm, accusing Chinese solar-panel manufacturers of selling products at below-cost prices in Europe.
The QBotix Tracking System rethinks two-axis tracking in an effort to bring the cost down to what solar project developers pay for single-axis trackers. Instead of having the hardware to adjust the angle on every solar panel, QBotix engineers created a traveling robot equipped with the motor needed to change the angle. Like a small train, the robot drives along a track a few feet off the ground placed along the edge of solar panels and makes adjustments. It’s designed so that one robot can service 200 panels in 40 minutes, the time it takes the sun to move 10 degrees. The track can be a simple loop or navigate turns and hills, according to QBotix CEO and founder Wasiq Bokhari. A magnet on the robot allows it to locate a panel mount, where it can attach its motors to make the adjustments.
Current stretched porous film battery separators for lithium ion batteries are thin, strong, and provide a good barrier between electrodes, at the cost of having very high internal resistance and low ionic flow due to low porosity and high "dead space" that come from starting with a solid material and trying to impart porosity. This work uses an alternative approach, where linear nanofibers and microfibers are combined in wet laid nonwoven processes to give separators that are strong and thin, but have higher porosity (60-70%) and so have much higher ionic flow.
Standards-based solutions were instrumental in the exponential growth of the Internet. For the Smart City, public electrical infrastructure ecosystem to expand, development, application and worker training of interoperability standards is an important strategic foundation from which to grow. This convergence of intelligent transportation systems with the Smart Grid, is allowing the Smart City concept to gain hold in many areas of the US and around the world.
As the technology of renewables advances, and as their track records continue to show stable returns, pension funds will continue to increase their investment in renewables, either through direct investment, infrastructure funds or private equity funds.
The S.P.M. Mill operators initially tried using Oscillator and Vortex technology flow meters. They found that these flow technologies contain moving parts or orifices and were unable to measure flows accurately at the low flow rate demanded by this digester application.
On average, a California solar system will pay for itself within five to 10 years, depending on the size of the system. However, if the system is leased and homeowners put little down upfront, the solar system will begin paying for itself on day one, creating instant savings.
The iSolar Exchange online marketplace is designed to create a secure site that connects the entire supply, manufacture, and delivery channels for solar and renewable energy products and services - worldwide. That's all we do - that's all we focus on.
In current technology about 30% of the light is reflected back into space. We have created a 3-dimentional structure in the silicon that virtually eliminates reflection by causing the light to bounce around within the structure until it is fully absorbed.
