Disclosure jerry phenomenon of Golden Sun PV projects

How to ensure the quality of products ? For example, look at solar photovoltaic modules, listed here from 2009 to 2012 for all PV modules Golden Sun project requirements . 2009 made ​​of monocrystalline silicon , polycrystalline silicon of the combined efficiency from 14% to 15% of early 2012 , the frame containing the 15% requirement . Certification standards from the earliest time due to the PV module testing capabilities are still inadequate , that time can only do testing and certification in accordance with the national standard 9535 , Golden Sun now requires that all components required to complete the project to test selected .

In addition, the requirements with Chinese characteristics , that is, the enterprise also has an additional qualification requirements . That Golden Sun Demonstration Project in the implementation process, I hope that some large-scale enterprises or service, quality assurance companies have joined , or the quality system more perfect business relationship , so in 2009-2010 from the registered capital of the enterprise for the component to production testing capabilities, and sales , as well as test equipment products , to provide complete enterprise 2011-2012 device proved to be used in Golden Sun demonstration project which , if not satisfied enterprises, the state requires these requirements very clear removable .

The inverter is also the maximum conversion rate of 94% from 2009 to 2012 97 %, with 95% of the transformer . There is mention that we are in the implementation of certification bodies accredited AQSIQ give us three choices , a national standard , one -line standard, one is certified technical specifications , so early in the implementation of photovoltaic , CGC is because the development of the certification standard, so does notappear in the PV inverter industry sectors much quality chaos , and now the technical specifications not only Chinese companies with foreign companies are certified to comply with the technical specifications .

In 2012 we were outlined pure sine wave power inverter companies , require companies to have a retention member , power analyzers, oscilloscopes , power quality analyzers, insulation tester and so on. Must constantly upgrade the product from the requirements of the technical requirements and production technology capabilities.

How to ensure project quality? CGC has developed a technical certification standards , and now all the Golden Sun Demonstration Project certification test must be carried out in accordance with the technical specifications. It contains some idea of ​​the future will be entered into the revised IEC standards among .

On how to verify the effective implementation stage , the National Energy Board to delegate Jianheng solely responsible for the audit and fund liquidation Golden Sun project. We often put together review and acceptance , and here I talk about the concept of acceptance is the acceptance of the owners themselves , the audit is equivalent to the liquidation of funds , we have to verify that you are the effective implementation of this project could lead behind 30 percent of the project is not all allocated to you, or in front of 70% of the funds to recover , we offer this advice to the National energy Board finances.

The audit team is led by CGC , but the key technical performance is recognized by the domestic industry to participate in the best laboratories . Investment accounting firms will be invited to participate in the audit project investment. Golden Sun demonstration project so any audit work is participatory , comprehensive consideration , so the Golden Sun project because of the above managed under strict conditions , there was no schedule, no lie subsidies phenomenon , it is precisely because of this measures to ensure the timely implementation of the Golden Sun Demonstration Project .

PV is difficult for SMEs to benefit

Although the " Golden Sun Demonstration Project" has been implemented across the country , and three-year total of about 700 megawatts ( According to the " 2010 China Wind Power Report " ) , the average annual installed capacity of nearly 250 megawatts , but some of photovoltaic products Manufacturers believe that companies did not enjoy the corresponding benefits.

To do a PV module sales in Beijing , said to reporters who , in 2010 the successful bidder of crystalline silicon photovoltaic modules only three , namely, Yingli China , Shanghai Solar Energy Technology , Jiangyin Hairun solar electricity. " We, as small and medium enterprises , is more difficult to enter the bid list , because our strength is still somewhat lacking ."

According to the relevant provisions of this year , the component companies need registered capital of 1 billion yuan, with more than 3 years the ability of independent production and supply of products and after-sales service . In addition, the production of crystalline silicon module testing capacity should not be less than 500MWp, without the three years 2008 to 2010 major complaints about the quality or contractual breach.

2011 's "Golden Sun" project implementation process, the Government of critical equipment " inverter" also provides suppliers need to Ministry of Finance, Ministry of Science, the National Energy Board in 2010 by winning enterprise unified tender determined .

The reporter learned that , in October last year and grid-connected photovoltaic invertersuccessful enterprises only eight other companies in 2011 will miss this round of Golden Sun projects.

One in Wenzhou enterprises engaged in the production of high-level inverter told reporters estimated there will be a new round of Golden Sun Project key equipment bidding by the end of July . By then there may be 20-30 inverter companies are expected to be added to the list in the bid . He mentioned that , after all, China has more than 300 off grid inverter manufacturer, and the quality is improving .

Ohm Nick's first "0" risk of solar PV inverter solutions for insurance products

Recently, from the world's leading news from an insurance company , Suzhou New Energy Technology Co., Ltd. ohm Nick ( hereinafter referred to as Ohm Nick ) solar PV inverter products, production systems and asset quality system has passed the scrutiny of insurance companies , successfully included in a list of companies can be insured . In the future, as long as the user selects ohm Nick insure that users install the power plant in the world , all environmental hazards by the product quality and other factors led to lower than expected earnings , insurance companies will provide compensation to the contract terms . It is reported that the move in the domestic solar PV dc to ac inverter industry, it is the first case .

        With the rising cost of electronic components , as well as rising labor costs , exacerbated by the inverter price competition among manufacturers , which for the inverter business is a challenge . Inverter products not raising theirprices , will reduce the profits of the enterprise itself ; forcibly if regardless of market prices , EPC providers and power plant owners will not be accepted. In this dilemma dilemma , the part does not focus on brand inverter companies will cut corners taken to replace components means to reduce costs . Such behavior had seriously disrupted the market order and good inverter directly on the power plant owners gain a tremendous impact .

        But insurance products enabled , the user within the scope of the contract , no matter the hardware , such as a short circuit due to equipment caused by the input power is halved ; or software problems caused by various types of outages , power output is zero ; longer or because severe cold, extreme heat while under the influence of the electricity generated by drop. Even products in the packaging, logistics and losses that occur during the insurance claims can enjoy , making the user's plant -income investments more protection.

        Ohm Nick Mr. Liu Anjia vice president of global marketing , said: "We are very proud to be the first to launch this innovative insurance solutions inverter companies , I believe we have designed is the best way to protect the interests of users ." He said as an enterprise set up not long , ohm nick has focused on less than 20 kW household-type machine development and manufacturing , and its firm " rely on the quality and development " concept among the well-known international brands. Steady development, Ohm Nick aware of the quality and credibility of the corporate brand for the importance of follow-up work will focus on spare no effort to promote product development and upgrades.

Ohm Nick: blue ocean in the Red Sea earn money

Latest research report shows that from 2013 to 2017, the global market for micro-inverter is expected to scale with the continued growth in demand in overseas markets grow more than four times. In the report came out before, there are many who see the PV industry micro-inverter great development potential, ohmic Nick Zhao Lei, general manager of New Energy Co., Ltd. is one of a.

It is reported that in January 2009, Zhao Lei and investors returning from Germany founded the Suzhou Esso, later, investors would like to get involved in the field of large-scale inverters, Zhao Lei, however, want adhere to the development of small and medium systems, and ultimately because of conceptual differences and parted ways . In 2011, Zhao Lei leave Esso, founded ohm Nick. Currently, Ohm Nick micro-inverter in theinternational PV market fast, and has received a number of national patent certification, which also verified in the choice of development path Zhao Lei foresight. November 1, 2013, the ohmic Nick China (Nanjing) International distributed energy and new urbanization Forum held a new conference, launched its blockbuster new - micro-inverters.

"With the advances in photovoltaic technology, photovoltaic power generation costs will continue to cost approach desulfurization coal price is expected that by 2016, China's photovoltaic power generation cost will be close to desulfurization coal prices, when China's photovoltaic industry will usher in the explosive growth in the future for distributed PV inverter market share in the future will account for about 70%. "Ohm Nick New Energy Co., Ltd., general manager Zhao Lei told reporters.

Simple, reliable, low cost, which is Zhao Lei to Ohm Nick formulate development strategies. "The future must be under the premise of guaranteeing quality spell costs." Zhao said, "Since missed the blue ocean, then we must consider how to survive and profit in the Red Sea." To achieve this goal, Ohm Nick has been the innovation as the main event.

It is reported that Nick ohms each inverter is equipped with WIFI built-in card, through a wireless router running status of the micro grid tie inverter is sent to the remote server, while also supporting peer to peer communications, which can be directly in the LAN on the inverse transformer monitoring, GPRS built-in card with mobile network automatically transmitted signal can be realized on a remote server without real-time fast network monitoring station area, more Ohm Nick from major hair GPRSKIT, WIFIKIT to provide users with convenient wireless control function, through Ohm Nick highly reliable inverter control device PMB enables remote management of the inverter active / reactive power regulation.

Compared to other brands of inverters, Ohm Nick's products can only be regarded as quite satisfactory in appearance, but the selection of components is very cautious, 95% of the company's inverter components are imported brands, This has to a certain extent, increased the difficulty of reducing costs. Since its inception ohm Nick, Zhao Lei continue to lead the technical team in the design optimization, value-added products is increasing at the same time seeks to maximize the reduction of costs.

According to reports, Nick ohm than conventional micro-inverter PV inverter has a generating capacity, high reliability, fine intelligence, installation and safety advantage, and relying on the company's strong after-sales service system to provide users with 24 hours worry-free service. Such products are very suitable for the user's home station, in the protection of resources and the environment, conserve electricity user input, generate additional power gains, real inverter monitoring, safety and other aspects have a strong advantage.

To 2017 micro-inverter market demand will grow more than 4 times

IHS latest research report shows that from 2013 to 2017 , the global market for micro-inverter is expected to scale with the continued growth in demand in overseas markets grow more than four times .

Compared with the traditionalmicro-inverter inverter , it has increased in many ways , such as functionality and efficiency . Because of this, micro-inverters are increasingly favored by the new market . Also been more and more non-US customers recognized and accepted . IHS recently released 2013 PV micro-inverter market analysis report shows that the global PV micro-inverter shipments will grow from 2017 to 2.1GW, 500MW , compared with 2013 increased by 306% .

Solar Micro-inverter solar modules is converted from a single DC to AC of a device. Compared to conventional inverters , micro inverters more expensive , but its output than conventional energy production or central inverters inverter device is much higher . Micro-inverter is now largely dependent on the demand for the U.S. housing market , but demand is slowly turning the focus of commercial solar systems department and other areas.

PV market analyst at IHS CormacGilligan said: " Micro-inverter is currently very popular in the U.S. market , the housing market has even more than 40% penetration rate , however, grid tie power inverter suppliers are trying to expand into new regions to increase or maintain its market share at the same time , micro-inverter many advantages , such as higher energy production , security, and component-level detection function , etc., for residential systems , especially small projects are still very attractive . "

2013 , micro-inverter shipments is likely to first break 500MW, however, competition and prices, suppliers will face many challenges. The face of the enormous potential of the emerging markets , many suppliers have introduced new products , SMA and Power-One is one of the two large-scale PV inverter manufacturer. 2013 , the inverter will be very fierce competition in the market , micro-inverter prices are likely to fall 16%.

Although the 2013 micro-inverter to achieve double-digit percentage price decline , but shipments grew rapidly, and its total income gains may still be more than 250 million U.S. dollars . However, the micro-inverter prices in the coming years will continue to decline. IHS predicts that the global micro- inverter market 's total revenue in 2017 will reach $ 700 million .

EnphaseEnergy as the world 's leading micro-inverter supplier in the United States last year, the largest share of residential PV market . However, as other micro-inverter increasing number of suppliers , the enterprises are facing increasingly fierce competition . Therefore , Enphase and other suppliers have Dingzhun new markets , and actively in the commercial sector to promote micro-inverter system development , in order to further expand its market share.

Enphase implementation strategy now has a growing signs of success . Recently, the company announced in Canada installed 2.3 MW solar project supply micro- inverter. Third of the world 's micro-inverter shipments will be included in commercial systems division in 2017 , while in 2012 this figure was only 9%. In addition, in 2017 , most of the micro-inverter will be used to scale the 10-100kW system .

Xi'an people achieve electricity self-sufficiency in the roof construction of power plants

" When you see the green light on the inverter indicator light , I knew would be ! " Recalled the scene when the successful generation , Lao Gao could not hide the look of pride , and even do the dishes that night Lao Gao , a small discretion about it, but he did not get too excited, he soon found that the electricity is not enough, sometimes a few hours of light to open no electricity .

"No, ah , television, computers also tens of watts, how it does not move with it ? " Then Lao Gao found reason : installed capacity of 175 watts of power generation equipment , home six lights add up to more than 100 watts, then coupled with PC TV , electric , of course not enough . At this point, Lao Gao decided to continue the transformation, he will be the first original tens of watts per bulb replaced only 3 watt LED lights , to reduce the electricalenergy generated by the inverter losses, Lao Gao will be home to six lamps circuit is directly connected to the solar power generation equipment , the formation of the rest of the plug circuit other way connected to the inverter circuit .

After transformation greatly, home power outages almost did not happen , "is that not all appliances used simultaneously, to avoid it to use , just normal use of electricity , like the other ! " Lao Gao said that encounter rainy weather can also be used because Xi'an long sunshine hours, usually excess electricity can be stored , rain no more than three days, so do not worry about the weather because no access to electricity .

October 10 afternoon, the Lao Gao a laptop at home flapper plug in the power cord , and then start the laptop, each electrical appliances after use, he unplug the power cord , is to be able to save energy. On the past , such a move will certainly not happen to him , " I would have is careless man, never pull the electrical plug before , sometimes asleep at night , television also opened a night, and now the use of solar power , the force get rid of these bad habits , because every 1 kWh of electricity hair is not easy ! "

Place on the 7th floor roof solar photovoltaic pure sine wave inverter panels where Lao Gao should go take a look at almost every few days , wipe the dust above , check for damage. Lao Gao just T account : His solar power generation equipment can send a kWh of electricity per day , one year is 365 kWh , according to 0.6 yuan per kilowatt basis, 219 yuan a year to save electricity despite investing more than 3000 yuan , need 10 years after to recover the costs , but Lao Gao that makes sense , "Now the community has been advocating low-carbon environment , but many are flow in the verbal , only for everyone to action , in order to truly green ."

Change in the situation brewing domestic solar market

Chinese solar energy industry has long been a high degree of dependence on international markets , enterprises are mostly taken by domestic production, foreign sales of the model . The future will be expected to completely change this situation , excellent solar energy companies will be the first to supply the domestic market with quality products .

"The solar industry is one of the few to maintain synchronization with the international competitiveness of the industry. Before us many companies regard the best product to get abroad , for the international market, in fact, we should leave the best products domestic users ." recently, the Shenzhen Changcheng electrical energy Co., Ltd. ( referred to as the Great Wall of energy ) responsible person said this.

Great Energy is a Fortune 500 company China Electronic Information Industry Group ( referred to as China Electronics ) 's solar industry backbone enterprises , mainly the production of solar inverter products , with products of independent research and development, production and sales , technical consulting, engineering turnkey , engineering design, installation and technical services such as a complete industrial chain, inverter products are exported to Europe , Asia and other countries or regions, cumulative production and sales of more than 2GW. In 2013 , the Great Wall received Satcon's quality assets , and further across the development, global installed capacity broke through 3GW.

"Satcon was originally founded by some MIT professors company with 30 years of history, once the world 's second-largest in North America 's largest utility-scale inverter manufacturers, strong technical strength . Wall Energy has received Satcon's trademarks, patents, proprietary technology , software , global certification qualification, production and development equipment, products , materials and other high quality assets, including tangible assets, intangible assets .

The original part of the technical backbone and sell Satcon will also join the elite Wall . We will these technologies , patents and the Great Wall itself deep accumulation of energy integration , our domestic and overseas design team design team full cooperation , the best solar power inverter products to domestic users .

The inverter will usher in a huge development opportunities

Optimistic about the long-term development of the photovoltaic industry . Although the global economic crisis has affected the process of development of new energy sources , but whether it is in order to achieve a low-carbon economy or to seek alternative sources of energy , photovoltaic will be the future focus on the development of the fields.

Gao Yuan Kun : With the cost of technological advances led declining subsidies for photovoltaic power generation will be less and less, after the PV grid parity will be great development . We expect 2012 global new capacity will be roughly flat with 2011 , but the Chinese market more than 75% growth.

Inverter companies will benefit from more domestic market growth. Currently, China's PV module production capacity has reached more than 70% of the world , the domestic PV market overcapacity and start on the global market in the range of cells and modules factory limited significance . The sine wave inverter industry contrast, China inverter enterprises in the global market share of about 3% , about 50% in China , China 's rapid growth in photovoltaic applications as the main market for the domestic enterprises is a new inverter added a lot of demands.

We projected 2011 global market capacity inverter industry is up to about 36 billion yuan , of which the domestic market up to about 2 billion yuan in 2012 to 2015 , the cumulative global inverter market up to 1600 billion yuan , of which domestic accumulated up to 160 yuan. Domestic enterprises will usher in a huge inverter development opportunities .

Gao Yuan Kun : competitive advantage is reflected in the cost, technology , brands and services. Through analysis, we believe that cost, technology , brands and services are photovoltaic dc to ac power inverter elements of the competitiveness of enterprises , domestic enterprises have advantages in terms of cost . With the inverter rapid increase in production capacity , prices will also lead to a decline in gross margin this year Inverter average of 30 % of the position where both the technology, brand and service business is expected to receive a larger share .

Access to the distribution network of distributed photovoltaic system to produce the eight affected

Centralized power distribution network generally radially . Steady state of operation , the voltage gradually decreases along the direction of the trend feeders . Connected photovoltaic power , due to the reduced transmission power feeder , so that the load node along the feeder voltage is raised , it may cause some load bus voltage excursion is exceeded, the voltage is raised to the access number of photovoltaic power location and size of the total capacity is closely related .

Under normal circumstances , can be in the low voltage distribution network settings OLTC transformers and voltage regulators and other pressure control equipment , the load node voltage offset control in compliance range. For the distribution network voltage regulation , a reasonable set of photovoltaic power mode of operation is very important. Sunny in the afternoon , the photovoltaic power output is usually large , if the line light loads , photovoltaic power will significantly raise the voltage of the access point .

If the access point is at the end of the feed line , the voltage of the access point is likely to cross the limit , then you must set a reasonable photovoltaic power operating mode , such as the provisions regulating photovoltaic power must be involved in the absorption lines in excess of reactive . Heavy-duty during the night time period , usually without photovoltaic power output , but still provide reactive power , improve the quality of the line voltage . Influence on the voltage photovoltaic power is also reflected in may cause voltage fluctuations and flicker .

Since the power output of photovoltaic solar irradiance with incident and change , it may cause local distribution line voltage fluctuations and flicker, if added together with the load change will cause a greater voltage fluctuation and flicker . Although the actual operation of photovoltaic power did not cause significant voltage fluctuations and flicker, but a large number of grid-connected photovoltaic power access when the access location and capacity for rational planning is still very important.

Usually considered a short circuit in the power distribution network side , the access to the distribution network, the power of the short-circuit current of photovoltaic contribute little , steady-state short-circuit current is generally higher than the rated output current of photovoltaic power is 10% to 20%, short circuit instantaneous current peak PV power inverter with its own storage elements and output control performance related . In the distribution network , plus short-circuit protection fuse overcurrent protection commonly used . For high penetration of photovoltaic power feeder road to short circuit fault occurs , probably due to the vast majority of photovoltaic power supply short-circuit current caused by the feed line can not detect short-circuit fault .

In 1999 , IEA-PVPS-Task-5 ( IEA Technical Working Group in PV ) in Japan, manufacturers have used four different injection control current inverter is connected to a power distribution line of the column adapter, then the transformer other side of the short-circuit tests. Tests showed that the short circuit current did not rise above 2 times before failure , 1 to 2 cycles to isolate a fault . In addition, Japan also a 200kWp photovoltaic power system short-circuit tests , the study found : short-circuit current through the transformer , the current becomes smaller , the transformer overcurrent protection does not operate.

In 2003, the United States NERL ( U.S. National Renewable Energy Laboratory ) has done on distributed power generation and distribution networks of interactions between . Adopt inverter http://www.gridtiepowerinverteronline.com/ way to access the distributed power , simulation prototype based on the 13.2kV ​​medium voltage distribution networks, distributed power capacity is 5MW, research is focused on fusing characteristics . The results show that when the single-phase and three-phase fault in the inverter way to access the distributed power to the small contribution of short circuit current , short-circuit current is mainly from the main network, or even more than 5MW induction motor to provide short-circuit current but also much smaller. Therefore, in order to control the current drawn into the photovoltaic power inverter not contribute to the short-circuit current conclusions.

PV inverters SMA thin breakthrough rapid price declines

Recently, SMA PV inverters giant lowered 2013 earnings data sparked widespread concern in the industry - 2013 annual sales of 900 million euros from -13 one hundred million euros down to 900 million euros -10 million euros, 80 million loss this year is expected to to 90 million euros .

SMASolar CEO Pierre-PascalUrbon to poor performance due to cost pressures and declining demand in Europe . He said , "As the world market leader , SMA particularly affected by changes in the global PV market impact , the market is characterized by high global price pressures . Moreover, the European demand for our core markets have fallen sharply, while the new Asian and U.S. markets is not able to make up . "

The past two years by the European debt crisis led to shrinking demand in Europe cut solar subsidies , overcapacity and other multiple factors , the global PV market landscape has been significantly change . European Photovoltaic Industry Association EPIA mid-year release of " 2013-2017 Global PV market outlook ," the report said, 2012 years ago, the European market, accounting for the global installed capacity of PV systems add more than 70% , in 2012 this proportion to 55%. This year, the vast majority of the world's new PV systems are installed in markets outside Europe .

On specific figures, in 2011 the European photovoltaic installed capacity reached 22.4GW, 2012 . Grid installed capacity reached 17.2GW. 2013 , Europe is expected to decline photovoltaic installed capacity will exceed 6GW. " Europe is the result of falling demand sales frustrated SMA main reason ." Inverter has been concerned about the development ofthe industry and is engaged in the industry for nearly 10 years, veteran Zhan- wide , said in an interview with reporters .

"This year, the focus has been China solar market , the USA, Japan , Australia and other countries transfer . Industry chain manufacturers should follow the pace of the market , to the transfer of these regions in the new market environment to make adjustments and respond . "In fact, this year, in March , SMA to 160 million yuan to buy MeV energy 72.5% stake in the new , just want a prosperous future in the Chinese market . However, the domestic inverter with charger market competition , coupled with the trend of sharp decline in prices , so that Big Brother SMA somewhat acclimatized.

However, the SMA Zhan- wide post more optimistic that next year will force SMA . He said , "Emerging markets will continue to grow in the coming years , the market is still many opportunities . SMA acquired after MeV love Faso internal integration and standardization takes time. Once SMA prepare future there will be a good performance ."

SMA to next year 's market is full of expectations. The company said in a statement for the performance down , " new products on the Japanese market in 2014 will help them to increase their market penetration in Japan , while the recombinant MVA new energy will increase next year 's sales in China . These developments , enable the company to return to profitability in 2014 and sales growth . "

PV manufacturing side or sustainable increase in earnings

Listed companies downstream part ( cells, modules , systems integration ) income continues to shrink, but the margin back to 10-20 % in the vicinity ; in upstream ( polysilicon , wafers ) annual revenue and gross margin compared to 12 were picked up , especially focused on the preparation of silicon wafer -scale enterprises in Central and Lungi shares shares revenue and gross margin ; materials ( glass, anti-reflection coated glass , edge material ) income scale stopped falling , but the gross margin continued to decline ;

Equipment sectors continue to maintain high gross margins , but continue to maintain revenues and order size 12 Annual Report of the trough ; amorphous component revenues and earnings are poor , many listed companies have stopped operations ; inverter link corporate revenueand earnings seriously divided , KSTAR gross profit margin than 12 annual rise, sun power even after years of net income scale power plants also have some impact on growth .

We believe that as technology advances and investor diversification , the future of the entire PV industry will continue to up the income scale , where photovoltaic manufacturing downstream side of the photovoltaic system side income and revenue in proportion to the manufacturing side tilt, a change since 2008 system side gradually inclined trend. Double reverse and the global manufacturing industry is changing opportunity to return . Therefore , we believe that the future profitability of PV manufacturing side or sustainable rise.

Corporate financial leverage and the proportion of current assets to total assets unchanged apart from participating in the overall operation of the power plant construction companies , other companies within the industry 's financial leverage and the proportion of current assets to total assets generally flat. We believe that the major components of the industry began to improve and enhance enterprise shipment target , does not mean that the device needs soon. Outsourcing and other light components of enterprise asset approach is the main way to enhance the production capacity .

on grid inverter, pure battery , component business turnover rate change for the better , in the upstream product , other downstream products, materials, equipment companies , operating capacity decreased slightly compared with 12 Annual Report . Most businesses operating cycle becomes longer, the number of days inventory turnover and accounts receivable turnover days were longer, low turnover rate .
