Solar photovoltaic output depends on orientation, tilt, and tracking
Tilt angles may reflect factors other than generator performance. Some installation sites may not be conducive to tilted arrays or specific orientations
Optimizing a Solar Array's Tilt and Module Spacing
System optimization is more than just good-looking charts - in this case, we are able to increase system profit by $40k, an increase of over 70% versus the 15º-tilt baseline design.
Q3 2014 Deal Volume Comparison
Acquisition activity in Q3 2014 was lower than most quarters in recent history. Activity was distributed relatively evenly across the solar markets in Europe, North America and Asia, with cross-continental deals accounting for the greatest number of transactions.
Solar cloth could stretch PV's applications
A British start-up has developed a way for parking lots and structures with roofs that can’t take much weight to harness the power of the sun.
The Cambridge, England-based Solar Cloth Company is beginning to run trials of its solar cloth, which uses lightweight photovoltaic fabric that can be stretched across parking lots or on buildings that can’t hold heavy loads, such as sports stadiums with lightweight, retractable roofs. Perry Carroll, Solar Cloth Company’s founder, told BusinessGreen that the company is working to close deals to install solar cloth on 27,000 parking lots.
“We have built a growing sales pipeline worth £4.2m [about $US6.57 million] for 2015, including park and ride projects, airport parking operators and retail park owners,” he said.
According to Solar Cloth Company, there are about 320 square miles of roof space and 135 square miles of parking space in the UK that could be covered by solar cloth, and if all of these spaces were covered, the solar power produced would be enough to power the UK’s grid three times.
Wind energy provides more than 2/3 of new US capacity in October
According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's (FERC) Office of Energy Projects, wind power provided over two-thirds (68.41%) of new U.S. electrical generating capacity in October 2014. Specifically, five wind farms in Colorado, Kansas, Michigan, Nebraska, and Texas came on line last month, accounting for 574MW of new capacity.
In addition, seven "units" of biomass (102MW) and five units of solar (31MW) came into service accounting for 12.16% and 3.69% of new capacity respectively. The balance came from three units of natural gas (132MW - 15.73%).
Moreover, for the eighth time in the past ten months, renewable energy sources (i.e., biomass, geothermal, hydropower, solar, wind) accounted for the majority of new U.S. electrical generation brought into service. Natural gas took the lead in the other two months (April and August).
Of the 9,903MW of new generating capacity from all sources installed since January 1, 2014, 34 units of wind accounted for 2,189MW (22.10%), followed by 208 units of solar - 1,801MW (18.19%), 45 units of biomass - 241MW (2.43%), 7 units of hydropower - 141MW (1.42%), and 5 units of geothermal - 32MW (0.32%). In total, renewables have provided 44.47% of new U.S. electrical generating capacity thus far in 2014.
SunEdison, TerraForm to buy First Wind for $2.4B
Solar company SunEdison and unit TerraForm Power said they would buy First Wind for $2.4 billion to enter the U.S. wind power market.
SunEdison's shares rose 6.6 percent to $17.70, while TerraForm shares rose 1.2 percent to $26.15 in after-market trading.
The deal comprises $1.9 billion in upfront payment and $510 million in earn-outs, the companies said.
Boston-based First Wind is operating or building renewable energy projects in the Northeast, the West and Hawaii, with a combined capacity of nearly 1,300 megawatts (MW) - enough to power more than 425,000 homes each year.
SunEdison raised its 2015 installation forecast to 2.1-2.3 gigawatts (GW) from 1.6-1.8 GW. TerraForm increased its 2015 dividend forecast to $1.30 per share from 90 cents.
TerraForm was created by SunEdison to own and operate its solar power plants. TerraForm went public in July.
The deal is expected to close during the first quarter of 2015, the companies said.

Utility of the Future
According to a new study by Berkeley Lab, distributed solar photovoltaics (PV) are the most immediate threat to investor-owned utilities and their shareholders, by depleting revenue from demand growth and need for capital investments in traditional power plants.
U.S.-China smackdown: America No. 1 in wind power
Climate-conscious Americans have long glanced enviously across the Pacific to China and its ever-growing number of often-gargantuan wind farms.
It turns out that they have less to be jealous about than previously thought: The United States has more wind energy powering its grid than any other country in the world, says a report by EDF Renewable Energy, the largest third-party provider of operations and maintenance for wind renewable-energy projects in the country.
Though China has more megawatts of wind turbines installed than the U.S—about 90,000 to America's 60,000—the U.S. actually produces more electricity that is delivered to the grid, which in turn reaches more businesses and homes. And while China's wind industry delivered less than 138 billion kilowatt-hours in 2013, the U.S.'s delivered more than 167 billion.
That's 20 percent more than China. And the U.S.'s generation has been growing steadily since 2008, when it first overtook Germany to become the world's No. 1 producer.
Why Google, Microsoft and Yahoo are buying up wind energy
Google, Yahoo and Microsoft are part of a growing number of tech and other major companies that are entering into long-term “power purchase” agreements (PPAs) with wind farms to ensure a steady stream of power, at a fixed cost, over a period as long as several decades. Most recently, last month Yahoo signed such a deal for wind power in the Great Plains with OwnEnergy, a wind energy developer.
Google -- which is already carbon neutral and now trying to power itself with “100 percent renewable energy” -- has the longest history here. It has three PPA deals in the U.S. wind sector (in Iowa, Oklahoma, and Texas), and two more in Sweden. Microsoft, meanwhile, currently has two PPA deals with wind installments located near its data centers in Texas and Illinois. The agreements provide 285 megawatts of power to help drive both Bing searches and also its other online platforms, according to Brian Janous, the company’s director of energy strategy.
What these deals have in common is that they involve purchasing clean energy in close proximity to the power hungry data centers that these companies operate -- data centers that in turn drive searches, apps like Gmail and much more. “These are very energy intensive operations that these companies are planning on running for years, and they know they need electricity,” says Emily Williams of the American Wind Energy Association.
Brazil gives go-ahead to 31 solar parks in push for new energy
Brazil finally entered the solar power sector on Friday, granting contracts for the construction of 31 solar parks as it tries to diversify its sources of generation amid an energy crisis caused by the worst drought in eight decades.
Brazil's energy regulator, Aneel, concluded its first exclusive solar power auction on Friday, clinching 20-year energy supply contracts with companies that will invest 4.14 billion reais ($1.67 billion) and start to feed the national grid in 2017.
The 31 solar parks, the first large-scale solar projects to be constructed in Brazil, will have a combined installed capacity of 1,048 megawatts (MW). Market expectations were for projected total awards of 500 MW.
"This auction is a mark, not only because it signals the entrance of solar power in the Brazilian energy mix, but because it was one of the most competitive to date," said Mauricio Tolmasquim, head of the government's energy research company, EPE.
The auction lasted more than eight hours. The final price for solar power came at around 220 reais ($89) per megawatt-hour, against an initial price of 262 reais ($106), an 18 percent discount.
"This is one of the lowest prices for solar energy in the world," Tolmasquim said.
Power storage group Alevo plan 1bn US battery plant
Could a long-vacant cigarette factory in North Carolina build the rechargeable battery that will unlock the future of the clean energy economy?
The Swiss-based Alevo Group launched the new battery technology on Tuesday. After spending $68.5m (£42.5m) for the factory, the group said it would spend up to $1bn to develop a system that would get rid of waste on the grid and expand the use of wind and solar power.
The project, a joint venture with state-owned China-ZK International Energy Investment Co, aims to ship its first GridBank, its patented battery array, to Guangdong Province this year, going into production on a commercial scale in mid-2015.
The container-sized arrays store 2MW and would be installed on-site at power plants.
Jostein Eikeland, Alevo’s chief executive, said in an interview that the company had an agreement with the Turkish state power authority, and was in discussions with US power companies.
“It’s a gamechanger,” he said.
“If we can take some of the massive energy that is wasted today by mismanagement of the grid and inject it where it is needed, everybody wins,” said Eikeland.
Eikeland said the company would create 2,500 jobs at the factory in Concord over the next three years.
The State of the Solar Industry in North America
The recent surge in storage activity has its roots in a general consensus being reached by stakeholders that the technologies are on a path that will enable them to achieve the cost, performance, and reliability targets that have been promised.
