I posted just now on a significant solar project at Palau International Airport, but it was just one of many featured in Cleantechnica’s latest weekly roundup of big solar news. From 200MW in Rajastan to 60MW projects in France and Germany, the future of solar is looking decidedly global if this week’s list is anything to go by. Given all the doom-and-gloom over solar that was spouted in the last few months of 2011, it’s good to see that capacity keeps building and interest keeps building. No wonder Warren Buffet is buying up large solar farms and Google continues its solar surge.

Solar Panels Creating Electricity for Much Longer than 20 Years

As indicated in a study Josh wrote on just a couple weeks ago, the lifespan of a solar power system is far longer than the 20 years most analysts use to calculate solar power costs. Last November, Susan featured one that was going strong at 30 years. A Facebook fan notes that solar panels at the Technical University of Berlin have been in operation for 31 years. Similarly, Kyocera, one of the oldest solar panel manufacturers in the world, recently posted on the fact that a number of its early installations continue to generate electricity reliably nearly 30 years after installation.

Tiny Island Nation Switches on Solar at its International Airport

From taking high-polluting nations to task for climate change to setting up a Mongolia-sized sanctuary for marine mammals, the tiny island nation of Palau, located roughly 500 miles east of the Philippines, has long been punching above its weight when it comes to environmental issues.

It’s latest venture is sending a clear message to the world—working with solar panel manufacturer Kyocera, Palau International Airport has just installed the nation’s largest solar array. Sure, its size (226.8kW) is not huge compared to the multi-hundred megawatt solar projects we see appearing around the world with increasing frequency, but it is still an important step forward.

India’s Tata Power to Divorce BP Solar

India's Tata Power to Divorce BP Solar

Email, RSS Follow

BP Solar is suffering a slow death that is hard to watch and reflects the cutthroat competition that marks an industry that used to be a lot more Pollyanna. The company is closing down and on Tuesday its joint venture partner, Tata Power, said it will buy out BP’s share in their enterprise.

Tata said it will purchase the 51 percent BP had in their Tata BP Solar joint venture, which was formed in 1989 and makes silicon solar panels and offers solar system design services. Tata didn’t disclose the purchase price. The joint venture is among the top three solar cell and panel makers in India, according to GTM Research.

The deal gives Tata total control of an operation that could benefit from India’s emergence as a sizable solar market. India’s central government wants to see 20 gigawatts of grid-tied solar energy and 2 gigawatts of off-grid uses by 2022, and it launched an incentive program in January 2010 that has auctioned off projects. A few states in India also run solar incentive programs. All these efforts are recent, so whether India can hit its goals still remains a big question.

The Good, the bad and the ugly Solar thermal energy

Email, RSS Follow

The technology for harnessing solar energy to generate heat or thermal energy is called solar thermal energy (STE). The US Energy Information Administration has classified the solar thermal collectors as low, medium, or high temperature collectors. Low-temperature collectors are used to heat swimming pools, while medium-temperature collectors can be used to heat water or air for private or commercial purposes.

Stunning Origami Solarcell Lamps Are Made From Folded Photovoltaic Panels!

Email, RSS Follow

Korea-born, Eindhoven-based Joon & Jung‘s Origami Solarcell is a polygonal low-energy LED lamp that is completely powered by the sun’s energy. The pendant lights are made from a flexible photovoltaic material that is folded into a 3D lamp using origami techniques. The flat-pack multi-faceted lights are still in the prototype stage, but we hope to see these innovative, energy-efficient designs hit store shelves in the near future.

Please forgive us the journalistic conceit of collecting these year-end trends — it’s a necessary evil we all put ourselves through. In solar, this year is a bit more nerve-wracking than last. Here are ten trends in a particularly dynamic and pivotal year that will echo into 2012.

Apple Files Patent for MacBooks Powered by Fuel Cells

Email, RSS Follow

If you’ve ever owned a laptop or a netbook, you know that their batteries come with a finite lifespan. But what about a longer lasting alternative to powering up your computer? Fuel cells, namely hydrogen fuel cells, not only boast a longer useful life, but they are also capable of running for weeks without requiring a recharge. Not surprisingly, it is reported that Apple is looking into using this technology, recently filing two patents incorporating the cells.

Sony demos paper-fueled battery

Email, RSS Follow

We’ve heard of gadgets being powered by some pretty crazy stuff, but how about paper? Sony recently showed off a new bio-cell battery that breaks down paper in order to create power. A paper battery sounds a little bit far-fetched, but the technology works, and could potentially change how we power devices in the future.

A solar hot water collector that makes electricity, too

Email, RSS Follow

The company today announced it raised $14 million in series C funding to commercialize a product that will draw electricity from solar hot water collectors. It will also make small chips able to convert heat from car exhaust pipes and industrial machines into electricity.

GMZ Energy, which was spun out of the Massachusetts Institute of Technology and Boston College in 2008, has created an improved material for converting the energy in heat into electric power. The process works in reverse so an electric current will produce heat.

Thermoelectric materials have been used for years in a few applications, such as heated seats in cars and portable coolers. Now a number of companies are trying to make them less expensive and more efficient at the heat-to-electric power conversion.
