National Energy partner selection Chint Power Systems 20kW three-phase string inverter type for the ten school supply.

October 2013 , Chint power and intention to reach customers , will provide more than 300 units of 20kW pure sine wave inverter solar projects in New Jersey . These projects included in a variety of applications, string inverters with the flexibility to adapt the structure of the advantages : the same inverter designed to meet the needs of the roof , garage or even tens of thousands of ground kW power plant .

Chint 20kW platform PHOTON Lab through independent testing in November 2011 and in other competing brands were rated as " one of the top ten inverters ." The product is 600V DC Input, Dual MPPT design , and with integrated fuse, DC and AC switch junction box . 2013 , Chint Power Systems has developed a new generation of 14kW and inverter 23/28kW1000V DC input , the products have passed UL certification, and has been into the market .

National Energy Partners LLC , said COO LouSabec said: " Chint is a superb company , which provides the most cost-effective solution for our inverter http://www.gridtiepowerinverteronline.com/ Chint these projects through the flexible application and lowest installed cost. improve the economics of our projects . "

Sales and Marketing General Manager , Americas market Chint Power Systems , said: " We are very pleased NEP chose Chint Power Systems America branch, and we are looking forward to have maintained cooperative relations throughout the project life cycle , including design , transportation, installation and on-site service . "

 Advanced Energy (AE) reports , Solar Energy ( photovoltaic inverter ) sector in 2013 third- quarter sales of $ 67.5 million , flat with the previous quarter , but before the introduction of a new flagship product , helps its order backlog increased to $ 45 million .

The company reported third quarter total sales of $ 142.9 million , while the 2013 second quarter was $ 139.7 million . Income from continuing operations was $ 687,000 , while the second-quarter loss from continuing operations was $ 9.8 million , income from continuing operations was $ 5.7 million .

AE Solar Division President Gordon Tredger said: "I am pleased to report that we returned to profitability , and our break-even point will be reduced to about $ sixty-five million due to be finalized next year our various restructuring and integration efforts , we expected to be further improved. because we are ready to ship in the fourth quarter of 1MW of AE 1000NX, we also see the construction of our backlog is satisfactory . "

After several years of restructuring, including outsourcing to China PV grid tie power inverter assembly , AE has positioned itself as a growing series of new products , and in 2014 on a wider geographical footprint of the rapid development of commercial rooftop and utility-scale market.

Tredger discuss quarterly financial results in a conference call , added: "cost reduction is very important for us , but we also focus on growth initiatives as part of our global expansion strategy , we see that in the next few years, promising regions such as India, Japan, Canada , the UK and the potential opportunities in South America .

We have already started in these countries optimized three-phase string type products , other products in our portfolio may be very appropriate. With us for roofs, garage and large ground- mounted applications, wide range of products , we believe that AE is quickly becoming a one-stop shop business applications . "

 Week view: PV: National Energy Board issued "on the solicitation of photovoltaic power construction scale 2013,2014 opinion letter", requiring limited power light does not appear abandoned the case in 2014 the scale of construction of photovoltaic power generation increased two percent, reach 12GW. Among them, Distributed PV 8GW, photovoltaic power plants 4GW. We recommend policies to promote sustained attention and performance in the industry to bring change for the better investment opportunities;

Focuses on both ends of the polysilicon and power stations, as well as the dc ac converter investment opportunities. Battery: four ministries in Shanghai reported to the State to promote the application of new energy vehicles explicit embodiment, the city will be the new layout 6000 charging pile, and new or updated public transport, logistics and sanitation and other vehicles, new energy vehicles not less than 30%. Recommendations concern the upstream lithium battery materials related business investment opportunities; remediation of lead-acid battery industry has brought increased concentration and long-term recommendations leading automotive starter battery camel shares.

Polysilicon fell slightly last week. According PVInsights sample statistics, PV grade polysilicon edged down 0.06% last week, two polysilicon price stabilization; polycrystalline silicon prices unchanged; solar cells decline of 0.52%; crystalline silicon module price fell 0.42 percent last week. For silicon, the battery fell 0.19%, the average price fell 0.76 percent silicon.

Shandong Province tariff provisions photovoltaic power dc ac inverter plant 1.2 yuan per kilowatt-hour. Shandong Province Price Bureau has recently issued "on the use of price policy to promote renewable energy and energy-saving environmental protection and healthy development of power projects notice." 2013-2015 grid photovoltaic power plant tariff determined as 1.2 yuan per kilowatt-hour (including tax), higher than the national benchmark price in part by the provincial commitment. We think: Shandong Province in the third category of the National Solar PV resource area, photovoltaic benchmark price of 1 yuan / kWh, the province will increase 20 percent subsidy, we plant internal rate of return is expected to be increased by 10 percentage points, to improve the investment enthusiasm of photovoltaic power plants .

 August 19 , Beijing Certification Center 's " micro-inverter technical requirements and test methods" through the National Certification and Accreditation Administration of expert review . Review Conference of the National Energy Foundation and managed by the Technical Committee of Standardization of new energy and renewable energy sub-technical committee chaired by the national commission Technology and Standards Management Department, China Renewable Energy Society photovoltaic special committee , the National Quality Supervision and Inspection of solar photovoltaic products Center , China Three Gorges New Energy Company , China Merchants new Energy Holdings Limited , Rheinland testing and certification services ( China ) Co., Ltd. , Baoding Tianwei Electric Automation Co., Ltd. and other units of the North more than 20 experts attended the meeting.

Expert review concluded Certification Center 's " micro-photovoltaic inverter technical requirements and test methods" in line with national Certification and Accreditation Administration of authentication technology management practices required to provide the definition of micro inverters , structure, mechanical properties, electrical performance and safety and other aspects of technical requirements and test methods, content of scientific and reasonable , in line with the use of micro-inverter requirements .

Review Group agreed that the certification by reviewing technical specifications , while giving a higher rating, that the certification specifications to fill the gap and improve the micro-inverter product quality , standardize the market, the development of China's photovoltaic industry provides technical support.

The shadow of the solar cell module locally , for different tilt angle and orientation , dirt , different aging , small cracks as well as different temperature and different photovoltaic panels easily cause mismatches in the output system, the drawbacks of reduced efficiency , leading to overall output power greatly reduced. This is the focus of the inverter difficult problem to solve .

To solve this problem , in recent years, a " micro grid tie inverter" new structure , i.e. each solar module is equipped with micro- inverter, the output of each module through the power optimization , the overall maximum output power , even if some solar panels by shadows , dust cover , etc. impact of micro-inverter power optimizer can still track the optimal local MPP ( maximum power point ) , salvageable significant loss of generating capacity. Meanwhile , micro power optimizer input voltage / current is converted to a different output voltage / current to maximize energy transfer system .
