Latest heterojunction c-Si ‘record breaker’ among Japan’s space and time-saving solar gadgets

weijing3333 4 years ago 0

A heterojunction c-Si solar cell with a conversion efficiency of 25.1% has been showcased by its maker at an event hosted by the Japanese government to exhibit technological innovations in “new energy”.

The government’s New Energy and Industrial Technology Development Organisation (NEDO) this week held a three-day “debriefing” where companies brought innovative products developed during Japan’s 2015 fiscal year, which ended in April. In Japan, clean energy is often referred to as “new” as well as by the term “renewable”. Products were shown off in the areas of solar, renewable or energy efficient heating, biomass, system interconnection and in marine energy, although solar dominated the numbers by some distance.
Solar industry products shown at the event, which took place from Wednesday until Friday, for the most part appeared to follow a common theme of space optimisation, especially in the ground mount and rooftop sectors, according to a summary of the event on the NEDO website.
In addition to the presentation of the 25.1%-efficient cell, which was created by a branch of Japanese chemicals manufacturer Kaneka Corporation in collaboration with NEDO, the products demonstrated included low cost tracking systems for installations on agricultural land, lightweight mounting systems for weak rooftops and specially designed modules for floating PV installations.
Kaneka’s 25.1% c-Si cell
News of Kaneka’s ‘record-breaking’ cell follows recent announcements by Japanese rival Panasonic and US installer SolarCity of record efficiencies measured for PV modules. Kaneka’s new device is a double-sided crystalline silicon cell, with the conversion efficiency verified by Germany’s Fraunhofer ISE.
The company announced in a press release (in Japanese) that it is targeting pilot production for the cells. Kaneka also said that it and NEDO were targeting cost reductions that could take the cost of energy down to Y14 per kWh by 2020 and then halve that to Y7 per kWh by 2030.
Finlay Colville, analyst with Solar Intelligence, said the new cell proved Kaneka had moved quickly in the crystalline silicon PV space, but that the jump to full commercialisation of the heterojunction cell would be the next challenge for the company.
“Previously Kaneka had been one of the early pioneers of amorphous silicon thin-film panels, and it was somewhat surprising a few years back when they announced having R&D activities in the crystalline silicon field. Until now, only Japanese rival solar company Panasonic has been able to commercialise the heterojunction, or HIT, type cell,” Colville said.
“The key question however now is whether Kaneka is simply looking to licence out its know-how, or look for partners to fund volume manufacturing plans across Southeast Asia.”
Innovating towards a grid parity-driven market future
The event took place amid rumours that the country is considering an auction process for future large-scale solar developments. Japan’s utility-scale PV industry, booming in the immediate wake of the feed-in tariff (FiT) being introduced in the summer of 2012, has more or less slowed to a crawl.
Following high profile issues over grid connection and political wrangles over the cost of renewable energy support, it is thought that with a few exceptions, such as projects on water or on otherwise unusable space such as landfill sites, unless projects can be executed at grid parity the utility-scale sector will be severely limited to some 57GW of already FiT-approved projects that have been submitted to Japan’s regional power companies and are forming a queue.
For this reason, the immediate future for PV in what is still one of the world’s top markets looks increasingly likely to focus on rooftops, both commercial and residential, but with an emphasis expected on the latter. As with other markets targeting near-term grid parity, the imminent departure of the FiT by 2020 at the very latest – if not before then – many of those selling into the Japanese market are seeing self-consumption of PV-generated power by households and businesses as the answer to keeping solar economically viable.
Another big change imminent that could alter the landscape is the expected deregulation of the electricity industry next year, with more than 700 new would-be providers already registering an interest in entering a field currently restricted to just 10 players, Japan’s regional power companies, which at present are also responsible for the grid in their own service areas.
At the PV Expo show held towards the beginning of 2015, many industry sources PV Tech spoke to said they expected this deregulation or “unbundling” process to make a significant change and in the case of Canadian Solar CEO Shawn Qu, a significant boost, to the PV industry.

Meanwhile in a recent interview, Japanese thin-film maker and developer Solar Frontier expressed the opinion that grid parity is not far away for Japan’s residential PV market and even including battery storage in system kits, expects unsubsidised solar to be viable within a “couple of years”.

Thai Stock Exchange cautions Superblock shareholders over acquisition of solar companies

weijing3333 4 years ago 0

The Stock Exchange of Thailand (SET) has warned shareholders of Thai utility Superblock about possible issues with a US$407 million investment in five solar energy companies, after independent financial advisor Sage Capital expressed concern about the acquisitions.


Earlier this month, Super Solar Energy Group, a wholly-owned subsidiary of Superblock, announced in a filing on the SET that it would acquire five companies with a combined capacity of 290MW of solar projects for THB14.45 billion (US$407.3 billion).

However, Sage Capital has cited issues with the acquisition of two out of the five companies, namely Energy Serve (ESERVE) and Power Technology International (PTI). Sage said their fair value is lower than the acquisition price.

Moreover, three solar projects from ESERVE have not yet been awarded PPAs from the Provincial Electricity Authority (PEA).

A new filing on the SET, which cited Sage, said: “There is still risk from these projects failing to obtain the PPA.”

Sage was also reported to hold the following opinion: “The condition for the five transactions requiring the company to make a huge payment in advance to the counterparties in each transaction is inappropriate and not consistent with the usual condition for sale and purchase agreements in general, which is considered unfair to the company and leads to an opportunity cost on the funds prepaid by the company to the counterparties.”

As a consequence, SET recommended Superblock’s shareholders to “carefully study” the Sage Capital report and attend an extraordinary meeting to be held on 30 October in Bangkok in order to vote on the deal.

Sage Capital did list some pros of entering into the five transactions, including strengthening income stability, boosting profits, increasing dividend payment ability of the Company and helping to create economies of scale.

Nevertheless it added the company would bear higher debt and interest burden from all the transactions. It also cited potential issues with delayed project completion, the subsequent loss of PPAs, followed by the loss of funds invested in land acquisition.

The SET filing concluded: “Considering all 5 transactions, IFA have an opinion that shareholders should not approve the investment in PTI and ESERVE.”

The Board of Directors and Audit Committee, however, still considers the transaction to be “reasonable” for the business with its strengthening of operations and revenue generation and therefore recommends that the shareholders approve the transaction.

China Sunergy restructuring manufacturing footprint

weijing3333 4 years ago 0

Struggling PV manufacturer China Sunergy (CSUN) is planning to relocate its manufacturing operations in China and expand its manufacturing footprint overseas in a major new move.


CSUN said that the actions were intended to improve its cost competitiveness and counter anti-dumping actions in the US, EU and potentially in other regions in the future.

Tingxiu Lu, chairman and CEO of China Sunergy said: "Since the inception of our first oversea[s] plant - Turkey plant, our efforts to diversify CSUN's manufacturing base [has] never stop [sic]. The move helps to enhance our global supply chain, gain access to local customers and minimise potential negative impacts from anti-dumping cases in the US, EU, or elsewhere. Looking ahead, we will continue to improve our cost competitiveness and strengthen our global footprint by the combination of moving our existing facilities in mainland China and building new facilities in the countries which have cost and geographic advantages."

The company announced the plans in a press release celebrating the formal volume production ramp at its new 200MW solar cell plant in Incheon, South Korea.

CSUN noted that trial production had successfully started in May 2015 and said the company would consider expanding production to 500MW with additional production lines once the facility has reached around 50% utilisation rates.

CSUN-branded solar modules would be produced by local Korean module assembly firms, according to the company.

The company was one of the first Chinese producers to establish an overseas plant, located in Turkey, to supply primarily customers in Europe.

CSUN had report revenue of US$91.5 million in the first quarter of 2015, compared to US$126.7 million in the prior quarter due to lower shipments to customers in China and Europe that generated a loss of US$12.2 million.

CSUN exited the first quarter of 2015 with cash and cash equivalents of US$32.4 million and restricted cash of US$147.4 million but has approximately $377.2 million in borrowings that fall due within 2015. The company raised going concern issues in its 2014 annual report.

It remains unclear at this time what the company meant by 'moving existing facilities' and calls to the company in China were not answered at time of posting.

building adopting GE Lighting’s Lumination™ ET Series Recessed LED Troffer

ofweekled 6 years ago 0
The modular headquarters of the Organizing Committee for the 2016 Rio de Janeiro Olympic and Paralympic Games is the first commercial building in Brazil to adopt GE Lighting’s Lumination™ ET Series Recessed LED Troffer, an ultra-thin fixture as thin as the width of a finger that brings modern styling to traditionally uninspired commercial ceiling spaces.

LED fixtures at Rio de Janeiro site will save half a million dollars in energy costs compared to fluorescent technology.
Approximately 3,000 Lumination ET Series Troffers offer an indoor lighting solution with lower energy consumption, longer life and lower greenhouse emissions resulting from power consumption compared with other options available in the market. The technology will help make the headquarters of 2,000 employees a benchmark in the search for more efficient solutions in the sports field and also will create an important legacy in infrastructure and technology for Rio de Janeiro and Brazil.
"LED technology plays a fundamental role in the model that sustains the environmentally conscious construction of the new headquarters for Rio 2016,” says Alexandre Ferrari, general manager of GE Lighting in Brazil. “We worked in partnership with Rio 2016 and the International Olympic Committee to create and enable a solution that combines energy efficiency, innovation and long-term, tangible benefits.”
By opting for the GE LED solution, Rio 2016 will save nearly half a million dollars on its energy bills over the four years the building will be used by the Organizing Committee. During this period, maintenance costs will be marginal, as the fixtures have an 11-year lifespan, approximately 120 percent longer than conventional fluorescent fixtures that last about five years.
"The headquarters of the Organizing Committee for the Olympic and Paralympic Games Rio 2016 is a project that seeks to use best practices in the adoption of energy-efficient technologies and solutions, creating an important and lasting legacy for the Brazilian society,” says Leonardo Gryner, operations general director for Rio 2016, “GE is certainly a strategic partner that contributed directly to achieving the goals of this initiative.”
The innovative design of the Lumination Luminaires allows greater lighting uniformity with fewer lighting points. When illuminated, the Lumination ET Series Recessed LED Troffers produce a perfectly even glow, delivering exceptionally uniform light to fill the space. While off, they appear free of a light source, while fluorescent fixtures are typically visible. The ultra-thin panels (0.5 inches) fit seamlessly in most common T-bar ceiling grids and feature a built-in dimmable LED driver to help make installation less complex and time consuming compared to traditional fixtures. As the Rio 2016 headquarters is a modular construction, the LED solutions will be available for future use after the closing of the Rio 2016 Olympic Games.
The lighting design for this building was completed by Peter Gasper, a well-known lighting designer for several major Brazilian landmarks.
LED technology is part of a range of energy-efficient and lower-environmental-impact solutions provided by GE for the Rio 2016™ headquarters. The company also is responsible for state-of-the-art technologies used in energy security and electrical distribution. The building also uses 25 Uninterruptible Power Supply units supplied by GE Digital Energy, which continue the energy supply for 10 minutes in the event of a failure while the generators are turned on, preventing the interruption of work. Electrical distribution components also have been installed in the building, including circuit breakers, relays, plugs and other equipment from GE Industrial Solutions.

Both the LED Lumination Luminaires and the UPSs are part of GE’s ecomagination℠ initiative, which helps customers improve operational efficiencies while allowing a significant improvement in their environmental impact.
GE has been an official sponsor of the International Olympic Committee (IOC) since 2006. Its commitment to contributing to the quality of the Games led the company to announce, in August 2011, the extension of its sponsorship agreement until the 2020 Games. Since the beginning of this partnership, GE has done more than $1 billion in Olympic-related business.

TCL made New Pioneer LED TV

ofweekled 6 years ago 0
ofweek  news - Pioneer’s long-awaited comeback in the television market has finally been confirmed with the announcement of three full HD LED TVs available in 40″, 46″ and 55″ sizes, scheduled to arrive in the Nordic countries this month before they land on UK shores early next year.

New Pioneer LED TV is rebadged Thomson made by China's TCL
No doubt this news will have many former devotees of the Japanese brand, which was known for producing awesome plasmas back in the day, drooling with anticipation – but wait! For things aren’t quite what they seem.

The “Pioneer” brand may well be slapped on the front of its new HDTVs, but these latest models are an altogether different proposition to its legendary Kuro plasma range. While we’ve yet to get our hands on a set, our research has led us to believe that the new Pioneer flat-screen TVs are in fact rebadged and rebranded Thomson tellies manufactured by Chinese consumer electronics giant TCL.

It doesn’t take a genius to work out how we’ve arrived at this conclusion. When Pioneer’s comeback was reported last month, we noted that the company would only be lending its name to ‘third-party’ television manufacturers in an exclusive deal with Dixons Retail Group. And now, with the launch of Pioneer’s new LED TVs, it’s not difficult to work out who those third parties are – none other than China’s TCL who sells televisions under its Thomson brand in European markets.

The new Pioneer LED LCD HDTVs – as seen on various Nordic ecommerce sites operated by Dixons Retail such as Lefdal in Norway and Elgiganten in Denmark – is a spitting image of the Thomson W6 series, as a quick comparison of the two models demonstrates. Many aspects on the Pioneer – the shape and size of the TVs, the discreet stand, the 6mm slim bezel, and even the royalty-free image of the little girl on screen – are identical to those of the Thomson.

Upon further investigation, we discovered that the two television models share many of the same features as well, including built-in DVB-T and DVB-C tuners, Smart TV functionalities like a web browser and Netflix app, DLNA streaming capabilities, active-shutter glasses (ASG) 3D, and USB recording.

It’s not a real surprise that someone like TCL would choose to license the Pioneer brand – after all, Chinese TV manufacturers are rapidly closing in on their Korean and Japanese counterparts, aggressively pushing products like their keenly priced 4K Ultra HD TVs into Western markets. The Pioneer name gives TCL an instantly recognisable brand that’s far more appealing than their own – even if it is just a repackaged Chinese display.

Pioneer’s new LED TV lineup is available in 3 screen sizes, namely the 40-inch L40S3D13N, the 46-inch L46S3D13N and the 55-inch L55S3D13N. In Norway, they retail for 6995, 8995 and 11995 Norwegian Krone respectively, which converts to around £700, £900 and £1200.

Keyence is excited to introduce the all new LR-T Series multi-purpose laser sensor. The LR-T is a perfect complement to the already solid Keyence sensor lineup with its superior detection stability, ease of operation, and unmatched versatility. Potentially limiting factors like target characteristics do not affect the LR-T’s detection ability allowing it to be utilized in a broad range of applications. It is also very durable and extremely user friendly making it suitable for virtually any sensing situation in any environment.
Keyence Releases A New Multi-Purpose Laser Sensor

Superior Detection Ability
The LR-T’s high level of detection ability is due to its Time of Flight (TOF) technology and custom integrated circuit. When paired together, the LR-T provides consistently stable detection over long or short distances, regardless of target surface type, color, or finish. Even environmental factors like ambient light, mist, or excessive dust will not affect the LR-T’s detection ability.

Ease of Operation

Setup and operation have never been easier. The crisp and precise OLED display screen clearly shows the operator all of the important values needed for setup, calibration, and operation. Intuitive menus make navigation through functions and settings fast and simple. A large, bright indicator light that can be seen from any angle specifies the status of the sensor to the operator. Wasted time and added frustration caused by complicated menus and ambiguous buttons are now a thing of the past. With the LR-T, troubleshooting and calibration couldn’t be easier!

Unmatched Versatility
Advanced features like an adjustable beam spot and application specific detection modes allow the LR-T to be configured and tuned to maximize performance in any situation, while its long-distance capability allows the sensor to be mounted out of the way and still deliver superior performance. Additionally, the LR-T’s compact and durable metal housing boasts an IP65/IP67 enclosure rating, making it suitable for both wash-down and other harsh environments.

Where sensors often fall short, the Keyence LR-T simply excels with its superior detection capability, ease of operation, and unmatched versatility, making it The New Standard in all-purpose sensors!
