SolarCity claims highest efficiency solar panel

Tristan Edist for the Business Spectator:  SolarCity, the largest retailer of solar systems in the US (over 30% market share) and partly owned by Tesla’s Elon Musk, has announced it will produce the most efficient solar module available on the market at 22.04% conversion efficiency. SolarCity is claiming it has therefore managed to pip SunPower who have been the longstanding holder of the most efficient conventional silicon solar module on the market. However in a subsequent discussion with Greentech Media, Peter Rive’s Chief Technology Officer conceded the majority of the panels coming off its pilot 100MW manufacturing line were hitting 21.8%.  In 2017 the company will be then moving production to a new 1 gigawatt per annum capacity plant in Buffalo which can sometimes encounter challenges with achieving stable quality levels during production start-up. SunPower claims 21.5% efficiency for its X-Series panel although often manufacturers will  have some variance in performance of panels and make claims based on conservative estimates of performance. Greentech Media quotes an anonymous Sunpower source saying that 22% efficient panels are already coming off its production lines.  In addition the company is targeting achieving 23% conversion efficiency from panels it will manufacture from its fifth fabrication line, scheduled for start-up in 2017.     Cont'd...

Renewable Energy Surpasses Coal in the UK

Written by Keith Kohl for Energy & Capital:  For the first time ever, more energy in the UK was supplied by renewable sources than coal. For an entire quarter. Wind, solar, and bioenergy checked in at 25% of the energy supplied. All of this was possible due to the fact that more wind turbines and solar panels were installed, which must be a good amount if you want to compare it to the same period last year, for which these energy options only accounted for 16.4% of electricity. Recently, the UK has been working to close aging coal and nuclear power plants. Of course, this will lead to its own issues... [Solar Panels] Conservative ministers collectively believe that the subsidies given to renewable energy were too numerous, going so far as to suggest plans for an 87% reduction of solar power, and to cut support for onshore wind farms. With that kind of spending cut, it's not surprising to hear that industry execs believe these actions would unjustly put an end to renewable energy just as it was gaining traction.   Cont'd...

Can the U.S. Jump-Start Offshore Wind Power?

By Camille von Kaenel and ClimateWire:  The Department of Energy has awarded around a half-million dollars to New York, Maine, Rhode Island and Massachusetts state organizations to cooperate on scaling up the offshore wind industry in the region.  Under the leadership of the New York State Energy Research and Development Authority (NYSERDA), the group will lay out a collaborative road map by the end of the year on how to build up the new industry. The project largely aims to reduce the cost of offshore wind projects, which has been a barrier to development, and establish a regional supply chain.  Industry and state representatives learned about the federal grant at the first-ever offshore wind summit hosted by the White House yesterday.  Offshore wind has struggled to take off in the United States. Europe, meanwhile, has more than 80 offshore wind farms with more than 10,000 megawatts of capacity. The White House summit marks a renewed effort to get the industry going in the United States, said various attendees.   Cont'd...

Balls of DNA Could Fix Geothermal Energy's Biggest Problem

Shara Tonn for Wired.com:  Geothermal Power has the potential to be cheap, reliable, and abundant—running off the heat of the Earth 24 hours a day, seven days a week. That’s especially true thanks to a new generation of home-grown geothermal plants, which don’t run off the steam of natural hot springs and geysers. No need to find those hydrothermal gems; today, geothermal engineers are making their own reservoirs by drilling down into hot rock and pumping in water. The catch? Engineers can’t see what’s happening underground. Drilling wells in just the right spot can be like playing golf blindfolded: Even if someone faces you in the right direction, you could still hit the ball way off the green. But tiny fragments of DNA dropped into the wells could soon help engineers follow the path of water underground, helping them sink their putts every time. In a basic geothermal plant set-up, engineers actually have to drill two types of wells. The first kind, which goes down two or three miles, carries cold water down deep, where it fractures the hot rock and creates new paths for water to move. It’s kind of like fracking, but without the chemicals.  Cont'd...

Researchers develop cool way to improve solar cell efficiency

By Kelly Hodgkins for Digital Trends:    A team of engineers from Stanford University have invented a cool way to improve the performance of solar panel arrays. A new material that the team produced literally will lower the temperature of solar cells even while they are operating in full-strength sunlight. As the solar cells cool, their efficiency will rise, leading to significant gains in the amount of energy harvested from the sun. Solar panel technology has improved by leaps and bounds, but the technology has a flaw that limits the efficiency of the system. The panels must face the sun to operate, but the heat from this exposure diminishes their ability to convert light into energy. The hotter they get, the less efficient they become. This issue has perplexed the industry for years, but the Stanford team may have discovered a material that can help dissipate this excess heat without affecting the operation of the solar array. The solution, proposed by Stanford electrical engineering professor Shanhui Fan, research associate Aaswath P. Raman, and doctoral candidate Linxiao Zhu, uses a material that is able to capture and emit thermal radiation (heat) away from the solar call. While deterring heat buildup, the thin, patterned silica material does not block sunlight, allowing the photons to enter the solar panel where they are converted to energy. It’s a win-win situation, allowing the free flow of sunlight and the removal of excess heat from the system.   Cont'd...
