Plan to streamline solar development in West OK’d

By JASON DEAREN Associated Press

SAN FRANCISCO—Federal officials on Friday approved a plan that sets aside 445 square miles of public land for the development of large-scale solar power plants, cementing a new government approach to renewable energy development in the West after years of delays and false starts.

At a news conference in Las Vegas, Interior Secretary Ken Salazar called the new plan a “roadmap … that will lead to faster, smarter utility-scale solar development on public lands.”

The plan replaces the department’s previous first-come, first-served system of approving solar projects, which let developers choose where they wanted to build utility-scale solar sites and allowed for land speculation.

The department no longer will decide projects within the zones on a case-by-case basis as it had since 2005, when solar developers began filing applications. Instead, the department will direct development to land it has identified as having fewer wildlife and natural-resource obstacles.

The government is establishing 17 new “solar energy zones” on 285,000 acres in six states: California, Nevada, Arizona, Utah, Colorado and New Mexico. More than half of the land—153,627 acres—is in Southern California.

Solar Panels Go Plastic – Light weight and easy to mount, what’s not to like

Here is the MIT report.

New Solar Panel Designs Make Installation Cheaper

Companies in Germany and China have made simpler designs that make it easier and quicker to mount panels to roofs.

With solar panel prices falling more than 80 percent in the last few years, many solar companies are turning their attention to reducing the cost of installing them. Two leading solar companies, Solon Energy, based in Berlin, and Trina Solar, based in Changzhou, China, have announced new designs for mounting solar panels to roofs—the companies say these designs can reduce the installation time by more than half, greatly reducing labor costs. The new designs reduce or eliminate the tools and hardware needed to install solar panels, and standardize solar installations, which have largely been ad hoc, reducing the time needed to design them.

While solar panels themselves used to account for most of the cost of large solar installations on commercial rooftops, the modules now account for about 40 percent of the cost. The rest comes from things like the necessary hardware, power electronics, and labor—which alone accounts for about 30 percent of the total.

Mounting solar panels on the flat rooftops of commercial installations typically involves anchoring long metal racks to the roof to create a framework that will angle the panels toward the sun and hold them together. Installers bolt the panels to this frame, wire the panels together, and electrically ground the racks.

Solar energy is ready, the U.S. isn’t

By Ken Wells
Published 5:07 p.m., Sunday, October 28, 2012

Clean energy has become a dirty word in presidential politics.

In their second debate, Mitt Romney and Barack Obama each tried to outdo the other’s love of fossil fuels: Obama extolling his record on oil and natural gas production, Romney vowing to take “advantage of the oil and coal we have here.” The Republican candidate has ridiculed the administration’s $535 million loan guarantee to Solyndra, the bankrupt solar panel maker, and accused Obama of living “in an imaginary world where government-subsidized windmills and solar panels could power the economy.”

The candidates’ coolness to renewable energy comes at a time when the domestic supply of traditional energy sources, such as oil and natural gas, is at an all-time high. And yet this failure to make the promise of renewables a keynote in the debate is a huge missed opportunity. In particular, it ignores the dramatic reduction in the cost of photovoltaic solar power worldwide and the considerable benefits to U.S. consumers and the environment.

Political roadblocks

The untold story of this campaign is that what killed Solyndra may turn out to be a boon for the nation. “Economically and technologically, the game is over,” said Bill Powers, a San Diego engineer and board member of Solar Done Right, a group that proselytizes for rooftop solar power. “The hang-ups in the U.S. are strictly political.”

Over the past five years the price of photovoltaic panels has plummeted 75 percent, due largely to a glut of Chinese-made panels. The fall in prices rendered technically advanced photovoltaic panels, like those produced by Solyndra and other U.S. companies, too expensive to compete.

Solar Islands – This is a great concept

They say nothing about storms or ship traffic so I am not sure how this would work in the real world.

Floating solar islands designed to power crowded cities

By on 29 October 2012

Not to be confused with what could be the biggest storm ever to hit the United States, SUNdy – a large-scale offshore solar farm concept by global consultancy and certification firm DNV – was unveiled at Singapore International Energy Week on Thursday last week.

The core feature of the floating solar concept is a hexagonal array of 4,200 solar panels – roughly the size of a football pitch – which floats on the sea’s surface. The ‘solar island’ would be capable of generating 2MW of power, with multiple islands joined together to create an offshore solar field of 50MW or more, producing enough electricity for around 30,000 people.

“The island has been optimised for solar capability and cabling efficiency,” says Kevin Smith, Global Segment Director for DNV KEMA’s Renewable Energy Services. “The solar arrays are divided into electrical zones feeding electricity produced into two main switches collecting the power for voltage step up at a central transformer (2MVA 480/34.5kV). From the offshore solar farm’s central island, 30kV electrical transmission lines connect, tying other islands in series to form a close loop and continue to the electrical sub-station onshore for grid connection.”

Sanjay Kuttan, managing director of the DNV Clean Technology Centre in Singapore says SUNdy’s thin-film 560W solar panels are flexible and lighter most silicon-based modules, allowing them to undulate with the ocean’s surface. “The key to creating an ocean-based structure of this size is the use of a tension-only design. Rather like a spider’s web, this dynamic, compliant structure yields to the waves, yet is capable of withstanding considerable external loads acting upon it.”

I normally would not think of Colorado as a solar state

Colorado Solar Power

Despite Colorado’s fame as a skiing destination, Denver actually ranks 30th of 174 major U.S. cities in terms of sunshine potential, not far behind Honolulu and Miami. In fact, Colorado has the third highest installed solar PV generation capacity of any U.S. state (source: IREC US Solar Market Trends 2009). As a result of innovative policies and greater awareness of environmental issues, Colorado was an early adopter of solar energy systems. As of the end of 2009, the state had 59 megawatts of installed solar PV capacity, third highest among U.S. states despite the fact that the state ranks 22nd in terms of population. In addition, Colorado installed 53.6 megawatts of solar power in 2010, ranking Colorado fourth in the nation, which was double the output for 2009 (23.4 megawatts). Home to natural gas, oil and some of our nation’s best solar rebates, Colorado plays an important role in the United States’ energy industry. Colorado was the first state to create a Renewable Portfolio Standard (RPS), through a 2004 ballot initiative. Originally, the RPS mandated that all utilities with more than 40,000 customers provide at least 10% of their electricity from a renewable energy source. Through additional improvements, it is now mandated that by 2020 investor-owned utilities must provide 30% and cooperatives and municipal utilities with over 40,000 must provide 10% of their retail load from renewable energy sources. Investor-owned utilities also have a distributed generation requirement, which is good news for solar owners. By 2020, 3% of the retail load must come from customer solar electric systems, rather than huge solar farms. This means that investor-owned utilities will continue to offer fantastic solar incentives to consumers to increase the number of residential and commercial solar systems

How to Organize, Finance, and Launch Local Energy Projects

Is it possible to “relocalize” energy? This is a critical question that must be addressed if we are to achieve true global resilience.

In our brand new book (September 4, 2012), Power From the People, energy expert Greg Pahl decisively argues that the answer is YES.

Power From the People is the second book in our Community Resilience Guides series, The book illustrates how communities across the country are already generating their own energy at the local level. From citizen-owned wind turbines to co-op biofuel producers to community-wide initiatives combining multiple resources and technologies, Pahl outlines the steps necessary and plan, organize, finance and launch community energy projects.

The book showcases over 25 real-life examples of local energy projects, offering a range of challenges and solutions that can be adapted and reapplied.

Yes I know about the fire at the Chevron Plant in the Bay area and what that adds to the idea that the oil and gas industry is purposely taking gasoline processing capacity offline as demand for gasoline falls to keep prices high. But solar is so much more peaceful and zen like.

This type of progress is just stunning. We are on the way to becoming a renewable country. Now if the rest of the world will follow suit.

New Mexico’s largest solar plant opens in Carlsbad

Posted at: 09/22/2011 6:10 PM | Updated at: 09/22/2011 6:16 PM
By: Joe Bartels, KOB Eyewitness News 4

Carlsbad officials unveiled the largest solar power project in New Mexico on Thursday.

Three of the five solar power plants in Southeast New Mexico went online, feeding enough electricity over the next 20 years to power almost 200,000 homes.

Eddy and Lea counties added the additional energy source to their already impressive portfolio.

“We have, of course, nuclear, we have bio fuels being produced down here, a vibrant oil and gas industry that’s doing fantastic and now we have solar,” said John Waters of Eddy County Economic Development.

The 100 acres of photovoltaic panels will track the sun’s movement in the sky for the next 20 to 30 years.

It’s all part of a plan to create clean, renewable energy and jobs.

“What we have is a facility that employed people for a significant amount of time, and will continue to do so over the next 20 to 30 years,” said Robert Reichenberger, Sun Edison spokesperson. “These panels and this facility are expected to last that long so we will continue to need people on the jobsite to monitor the project.”

Out of the three power plants online, two of them are in Jal and one is in Carlsbad.

The two offline – in Eunice and Monument – are expected to be generating power by the end of 2011.

“It shows we’re ahead of the rest of the state in this type of energy production and we like to think of ourselves in Southeastern New Mexico, particularly Eddy County as being a major contributor to the energy industries across the country,” said Waters.

Because of the power of the coal industry and the oil industry, China is so far out in front of American that it is not even funny. It so pitiful that we let all of this happen under George Bush’s watch. He built the biggest wind farms in Texas and then dropped the ball at the Federal level. We never may actually be able to catch up.

About 2 years earlier there is evidence in the literature that the Botswana government let bids for a 200 megawatt facility. So why this one is for a little over a meg., I got no idea. And there are no pretty pictures either.

BG correspondent The P85 million 1.3MW Photovoltaic Power station in Phakalane will not only serve to diversify the country’s energy sources but also boost the country’s economic relations with Japan. The Japan-sponsored clean energy plant is expected to be complete in September this year. The plant is part of government’s investment in the energy sector. Speaking during a progress tour of the Power Station on Wednesday, Mineral and Water Affairs minister, Ponatshego Kedikilwe said: “This arrangement will not only boost our economic relations with Japan but will be beneficial in the diversification of energy sources,” as it will lessen the pressures of rampant energy shortage. Phillimon Dhafana, the Manager of the Planning and Projects in Rural business unit from Botswana Power Corporation, explained that the power plant would generate uncultivated solar power. Dhafana told the Botswana Guardian that, “our country experiences plenty of heat that these power plant will harness and convert to solar energy that will benefit the whole country.”

Dhafana said the difference between Morupule power station and this new project is that the solar power plant produces clean energy while the Morupule plant emits coal gases, which destroy the greenhouse. The power station is expected to be complete in September.

USA: 3.4 MW Conergy plants for largest carrot producer worldwide

31. July 2012 | By:  Conergy

Conergy is achieving additional successes in global solar growth markets. In the USA, the system supplier secured two major orders for three power plants with a first phase total capacity of 3.4 megawatts for the world’s largest carrot producer Grimmway Enterprises Inc.

Additional plants totaling 2.3 megawatts may follow at other Grimmway facilities in the future. In 2010, Conergy already helped Grimmway to produce ‘greener carrots’ by installing a 230 kilowatt plant in Arvin, California. At 3.4 megawatts, the new order is 14 times the size of the first Conergy power plant on the Grimmway farm.

30% of the power demand of the Grimmway farms covered by Conergy power plants

By the end of 2012, Conergy will have completed construction of the first three solar power plants with a total capacity of 3.4 megawatts on three carrot plantations in the Californian Central Valley, in Malaga, Bakersfield and Lamont. In a second phase, two other solar energy plants with a total capacity of 2.3 megawatts may follow at other Grimmway facilities. The 4,760 Conergy PM modules at the three power plants will be producing millions of kilowatt hours of clean power every year. This will allow the company to reduce its electricity costs, and it will cover 30% of the power demand at its carrot farms, including its 100% organic farm. In addition, the power plants will prevent the emission of more than 2,700 tonnes of damaging CO2. This makes for ‘greener carrots’ in two ways: through purely organic growing methods and through clean energy generation.
