Foil resisters help measure DC and AC in solar projects

Foil resisters help measure DC and AC in solar projects

http://bit.ly/2nuxEPh

Regardless of size or location of a solar installation, the need for a good resistor remains. Resisters are used in solar PV applications for high-precision current measurements within the system.

Solar panels produce DC current, so it’s necessary to ensure accurate current measurements for the proper adjustments of the inverter to its correct working settings. On the inverter output side, resisters ensure current measurement accuracy. At the same time, measured current provides data as to the amount of AC energy output. 

The VPG Foil Resistors product group of Vishay Precision Group, manufacturers of precise and stable Bulk Metal Foil resistors, announced the global market launch of the Powertron PCS Series, a high-reliability power current sensor family, offering exceptional long-term stability, reliability and performance.

Design of the Powertron PCS Series incorporates VPG’s own proprietary Bulk Metal Foil technology, combining high-precision resistors with both high power and a low temperature coefficient of resistance (TCR). The result is a power current sensor which offers truly industry-exclusive, high-precision measurements, without the need for compensation for external temperature effects. Units are offered in 73 unique standard packages, with resistance ranges from 1 mOhm to 10 Ohms, a TCR down to 3 ppm, and load stability and resistance tolerances to ±0.01%. They are lead free and RoHS compliant. To meet 30 Watt power requirements, the PCS Series may be further mounted to an external heat sink. This allows them to provide three times more rated power than any other comparable industry model.

The Powertron brand of VPG Foil Resistors specializes in the design and manufacture of reliable high-precision resistors and power current sensors. Hundreds of standard model configurations are derived from one of the industry’s most extensive portfolios of customer-selectable housings, materials, substrates, and metal foil grade combinations. Depending upon selected model, individual resistor networks may be reconfigured prior to shipment, at customer request. High-precision Powertron resistors feature multiple metal foil grade options, including CuMnSN, CuNiMn and NiCr, which are integrated along with VPG’s own patented Bulk Metal Foil technology to create high-reliability finished product designs. For high-power applications, VPG designs and manufactures its own Powertron thick-film chips, featuring less demanding load stability, TCR and resistance tolerances. Custom packages, configurations, parameters, and specifications may be further produced in OEM volumes with competitive lead times. Please consult the factory for details.

For added customer convenience, all Powertron standard products are accompanied by full 3D support of individual part designs for the BOM, including PCB libraries for layout support. Typical applications for the Powertron PCS Series include medical instrumentation, high-end measuring equipment, high-precision power supplies, battery management, and power converters. They may also be used as effective drop-in replacements for legacy competitive models, in applications where extended performance and a low TCR are required.

Solar MLPE companies must innovate products to reduce prices, report says

Solar MLPE companies must innovate products to reduce prices, report says

http://bit.ly/2m2zee6

-SolarEdge

The module-level power electronics industry is witnessing an intense growth phase, according to global research and consulting organization Frost & Sullivan. Demand is driven by increasing solar PV installations across the globe and modernization of grid infrastructure capable of accommodating module-level power electronics (MLPE) technology within the system.

“With movement towards renewable power and distributed power sources, the MLPE market is expected to sustain further significant growth in all regions of the globe,” said energy and environment research analyst Manoj Shankar. “To gain a competitive advantage and increase market share in a highly consolidated and fiercely competitive market, MLPE companies must innovate their products to reduce prices, seek geographic expansion and invest in partnerships or merger and acquisition strategies.”

Global Module Power Electronics (MLPE) Market, a report that is part of Frost & Sullivan’s Power Generation Growth Partnership Service (GPS) program, found that the market is expected to grow from $648.7 million in 2016 to $1.16 billion in 2021 at a compound annual growth rate (CAGR) of 12.4%.

Other developments include:

  • Reduced MLPE costs will lead to a higher adoption in many developed and developing nations.
  • The total MW-level MLPE installations are expected to increase from 3.3 GW in 2016 to 10.7 GW in 2021 at a CAGR of 26.2%.
  • Enphase Energy and Solar Edge Technology are the two major players that dominate the market due to their early mover advantage.
  • Prices of microinverters and DC optimizers are expected to be on par in the near future with traditional inverters, leading to higher adoption by consumers.

“Renewable energy targets and regulations are set to play a major role in the development of the MLPE market as countries move towards more efficient and sustainable power generation,” noted Shankar.

Frost & Sullivan, the Growth Partnership Company, works in collaboration with clients to leverage visionary innovation that addresses the global challenges and related growth opportunities that will make or break today’s market participants. For more than 50 years, we have been developing growth strategies for the global 1000, emerging businesses, the public sector and the investment community.

4 consortia apply for Turkey’s largest solar power plant

4 consortia apply for Turkey’s largest solar power plant

http://bit.ly/2mQGUPv

A total of four consortium groups, along with their foreign partners, have applied for the tender for the Karapınar Renewable Energy Resource Area (YEKA) where the largest solar energy power plant in Turkey will be established.

According to Anadolu Agency’s (AA) reports based on Energy and Natural Resources Ministry sources, companies submitted their bids for the Karapınar YEKA. The application deadline ended on March 14. A total of four tenderers – the consortium of Limak – CMEC – Hareon Solar, the consortium of Kalyoncu – Hanwha Group, the consortium of Çalık Enerji – Solargiga and the consortium of AKC and Güneş – offered bids for the 1,000-megawatt Karapınar YEKA, which is to be built in the Karapınar Energy Specialized Industrial Area.

The tender will be held on March 20, 2017 with the participation of firms fulfilling technical and financial qualifications. A reverse auction model based on the electricity price, which has a purchase guarantee, will be pursued.

Within the scope of the tender, a plant with a production capacity of a minimum of 500 megawatts of photovoltaic modules per year will be built in Turkey and a capacity of 1,000 megawatts will be allocated to the Karapınar YEKA on condition of carrying out research and development (R&D) activities for the next 10 years.

The photovoltaic modules to be produced in the factory, which is to be built in the 21 months after the contract date, will be used in the field. Karapınar YEKA-1 Solar Power Plant tender will be the first practice in the energy sector to be based on the condition of localization and YEKA-based price determination.
