Sanyo's new 2-sided solar panels deliver 50% more energy

Sanyo's HIT Bifacial solar panels raise the bar in the solar industry

Sanyo has introduced their newest solar panel – the HIT Double Bifacial, a new type of photovoltaic that raises the bar for the solar panel industry.

This revolutionary system lets solar panels generate power from both sides simultaneously, using Sanyo’s HIT (Heterojunction with Intrinsic Thin-layer) proprietary bifacial technology Its two glass layers increase the amount of energy produced by up to 30% compared to a single-sided HIT solar panel – delivering 50 percent more power per square inch than the average solar panel.

DuROCK Alfacing International Inc., a Canadian company specializing in innovative interior and exterior coatings, has combined these new solar panels with its  Tio-Coating reflective white roof membrane, which reflects up to 89% of the solar radiation. This lets the double-sided solar panels do double work, said Gary Campacci, President of DuRock.

Sanyo HIT Bifacial solar panels 2Sanyo officials said the company’s products have the world’s highest solar-light-to-electric-energy conversion efficiency per installed square foot.

According to the Statesman Journal, a Salem, Oregon factory that produces silicon for Sanyo HIT panels has just entered production.

And so another step forward for the solar industry. Stay tuned to see where it goes next!

Environmentalists outraged at prospect of mining in Bristol Bay, Alaska

Bristol Bay, Alaska 1The proposed Pebble Open Pit Mine  – which would be the largest North American copper and gold mine – has outraged environmentalists who see Bristol Bay, Alaska as a “vital ecosystem” for salmon and other species.

The threat puts the headwaters of the two most famous salmon producing river drainages in Alaska –the Mulchatna/ Nushagak River drainage and the Newhalen / Kvichak River drainage, both of which feed into the renowned Bristol Bay – at risk. Anticipated to be the first of many, the mine would also include the largest dam in the world – larger than Three Gorges Dam in China – and would be made of earth, not concrete, to hold back the toxic waste created in the mining process.

Alaska's wildlife and salmon habitat would be at risk with the proposed Pebble Mine

Bristol Bay – home to the world’s largest sockeye salmon fishery – is a pristine premier fishing and wildlife area. Its waters are the source of the most productive commercial and sport salmon fisheries in the world. Many native groups and commercial fishermen are opposed to the proposed Pebble Mine.

 

According to the National Resource Defense Council:

 

“The only way to extract the low-grade ore from the region would be to use a brutal and pollution-prone technique known as hard-rock mining, which includes powerful explosives and massive drilling equipment. At one of the proposed mines in Pebble, a remote, roadless area sandwiched between two national parks, spongy, lake-studded tundra would be scraped away, leaving a yawning two-mile-wide, 2,000-foot-deep pit in its place. This would be the largest open-pit mine in the world — wide enough to line up nine of the world’s longest cruise ships end to end and deep enough to swallow the Empire State Building. At a second mine, explosives would be used to create a series of underground cave-ins to extract ore.”

Bristol Bay, Alaska 3While posing a potentially terrible risk to the environment, this project would actually provide little economic benefit to Alaskans.

According to the EPA, the hardrock mining industry is the single largest source of toxic releases in the U.S.  According to Lance Trasky, former ADF&G Habitat Regional Division Supervisor for Bristol Bay for 26 years:

 “If mine permitting is allowed to proceed under current state and federal standards and permitting processes, the very large scale mining of sulfide based copper ore in the Nushagak and Kvichak drainages will physically destroy thousands of acres of very high quality spawning and rearing habitat and over time will almost certainly seriously degrade fisheries habitat and fisheries production in downstream portions of these drainages.”

As former Governor Jay Hammond said “I can’t imagine a worse location for a mine of this type unless it was in my kitchen”.
