To Meet New U.S.-China Climate Change Agreement, Solar Needs Level Playing Field

$

The agreement between President Obama and China President Xi Jinping to reduce greenhouse gas emissions has been hailed as an important advance in the long history of international climate negotiations.

Under the agreement, the United States has committed to achieving an economy-wide target of reducing emissions by 26 to 28% below 2005 levels by 2025. China has agreed to a peak emissions level in 2030, with levels then remaining steady or beginning to decline.

As a clean, renewable source of power, solar can be expected to play a big part in helping the United States achieve this goal. However, while solar has entered the mainstream — it accounted for more than half of new electric generating capacity added in the first half of 2014, according to SEIA (the Solar Energy Industries Association) — it still makes up only a miniscule portion of the U.S. energy supply — 0.23% in 2013.

Which raises the question: what can policymakers do to speed the adoption of solar and thus help the nation meet its commitment under the agreement?

While the costs of solar have declined dramatically in recent years, in order for solar to truly compete with electricity produced from fossil fuels, we need to level the playing field. Critics of clean energy claim that it is only economically viable due to government subsidies, however, fossil fuels are supported by an array of valuable subsidies that dwarf those received by renewables.

According to the 2014 World Energy Outlook from the International Energy Agency, worldwide fossil-fuel consumption subsidies were $548 billion in 2013 — more than four times the value of subsidies for renewable energy. “Fossil fuel subsidies rig the game against renewables and act as a drag on the transition to a more sustainable energy system,” the IEA said. In the United States, the average annual subsidy is $4.8 billion for oil and gas, compared to only $370 million for renewables — or about 13 times more.

These numbers don’t account for the externalities of the health and environmental burden of burning coal and other fossil fuels, which costs an additional $500 billion, according to Harvard Medical School.

In a truly free market there would be no subsidies, but as long as fossil fuels benefit from direct and indirect incentives — including tax incentives for exploration, drilling and leasing equipment, as well as retail price support through strategic oil reserves and below-market costs for drilling and mining rights — the solar industry will also need incentives if we are ever to make the transition to a low-carbon economy.

The most effective way to level the playing field would be through a national cap and trade program under which large emitters would be penalized for releasing greenhouse gas emissions. But the 111th Congress, dominated by the Democrats, failed to adopt such legislation in 2009 and it’s highly unlikely that a new Congress dominated by Republicans will succeed in this political environment.

Which brings us to the Environmental Protection Agency’s Carbon Pollution Standards for Existing Power Plants, proposed on June 2, 2014. The Clean Power Plan is projected to achieve an overall 30% cut by 2030 from 2005 emission levels through the establishment of target emission rates for each of the states based on regional variations in generation mix and electricity consumption.

Since renewable energy is one of the options included for cutting carbon emissions, the plan should help level the playing field between fossil fuels and solar. But there is more that can be done, specifically an extension of the federal Investment Tax Credit (ITC), a solar incentive that offers a tax credit for 30% of the upfront cost of installing solar. The ITC is currently slated to be reduced from 30% to 10% at the end of 2016.

Though solar saves money on electricity costs over the long run, a major barrier to increased adoption is its high upfront cost. The ITC has helped overcome that barrier by incentivizing tax equity investors to fund solar projects. SEIA, the leading solar trade organization, has called the ITC one of the most important federal policy mechanisms to support the deployment of solar.

Since the ITC went into effect in 2006, investment in solar has exploded. Solar installations in 2014 will be 70 times higher than they were in 2006 and by the end of this year there will be nearly 30 times more installed solar capacity, according to SEIA, which is pushing hard for an extension of the ITC past 2016. In addition, more than 143,000 Americans are currently employed by the industry.

Critics of the agreement with China are charging that the U.S. has been hoodwinked — that the U.S. economy will be hamstrung by the new emissions goals, giving China an unfair advantage in the global economy. Nothing could be further from the truth.

Solar is now a big business in the United States, creating new high wage jobs, spurring economic growth, lowering energy bills and reducing harmful greenhouse gas emissions.

But it could be a lot bigger. Indeed, the new agreement can serve as the stimulus for the United States to take the lead in the transition to a low-carbon future, with all that implies in terms of a competitive advantage in the global economy.

In other words, rather than hamstringing us, the agreement serves our national interest by allowing us to draw on our technological prowess and can-do spirit to usher in a new energy age. But in order to support the development of clean, renewable energy we need to protect the incentives we have, such as the ITC and the Clean Power Plan, and develop new ones to give solar a fighting chance against fossil fuel technologies.

Winter Storage and Maintenance Tips for Flooded Lead-Acid Batteries on Solar Installations

$

Golf CarFlooded lead-acid batteries have charge and discharge rates that depend highly upon temperature. While warmer climates tend to speed-up charging and discharging rates, cold winter months can slow down the rate of charge/discharge. Because most flooded lead-acid batteries used in renewable energy applications are stored indoors, they’re not always subjected to freezing temperatures. Nevertheless, the cold can still increase the resistance in the battery’s chemistry and cause a reduction in capacity and charge acceptance. Therefore, it’s important that your bank of batteries remain in a location where the temperatures can remain preferably between 50-85°F degrees (10-29°C).

A general rule of thumb: A battery loses 10% of its capacity for every 15 to 20 degrees below 80°F (27°C). With this in mind, you can calculate your power needs and add more battery banks to compensate. Much of this greatly depends on the conditions in which your batteries are stored. While it may sound better to keep your battery packs closer to boilers and other sources of radiant heat, problems can arise when some batteries are warmer than others, particularly if the battery charger is connected to the batteries and to AC power for maintenance charging. Battery manufacturers recommend keeping your batteries in a room that has a consistent temperature. They also recommend that your storage area should have plenty of space between the batteries and between the walls of the enclosure so that air can circulate and help provide some insulation. Also ensure that there’s ventilation in the room and that your batteries are away from any other electrical components that can cause a spark.

With the proper conditions, you can also determine the state of charge of your batteries by simply checking each one with a hydrometer. The ability to check specific gravity readings in flooded lead-acid batteries is an advantage in cold weather operation. It allows the operator to fully understand the effects of cold temperature on the batteries and allows them to be properly maintained. As a rule of thumb, subtract four points (.004) from your hydrometer reading for every 10 degrees below 80°F (5.6 degrees below 27°C). For example, if the temperature of the electrolyte is 50°F and your battery’s specific gravity reading is 1.200, you must subtract .012 from your reading. In this case .004 for every 10 degrees equals .012. Subtract this from 1.200 and your corrected specific gravity reading is 1.188. In this example, the battery cell is less than 50% charged.

Knowing how your batteries operate in cold weather conditions can greatly help you keep track of your battery packs’ health and, more importantly, allow you to maintain your power needs when you need it most.

innovative-solar-systemsInnovative Solar Systems (ISS),  based in Asheville, N.C., has developed about 1 GW of solar farm projects in the state prior to expanding operations across the entire U.S. The latest group of solar farm projects approved in the state are a combination of 2-MW and 5-MW projects. Small to medium size investors prefer small projects, according to ISS CEO John Green, due to the smaller capital outlay, faster commissioning time and returns that range from 10% to 20% over the life of project.

North Carolina has been a leader in solar development for many reasons, including above-average tax credits and incentives that are offered in the state. It is quite common for the tax equity investor to fund a large portion of a solar farm cost making the returns quite attractive for the debt equity investor involved in each deal, according to Green.

“We have seen a whole new type of investor sucking up these solar farm projects due to the fact that a person or entity is able to structure deals in such a fashion where the purchase power agreements are offering the pure equity investor long term income streams, while the tax equity investor funds a large portion of the construction finance,” says Green.

JA Solar has shipped 100MW of modules to the first large-scale solar farm in Pakistan.

Occupying 500 acres of land, the solar farm is located within the Quaid-e-Azam Solar Park in Bahawalpur, Pakistan. The Solar Park will serve to address the country’s energy shortage and is a key project of the China–Pakistan Economic Corridor, an under-construction development program for energy and infrastructure projects to connect China to southern Pakistan and develop a new gateway for trade. Energy demand in Pakistan has grown approximately 8 percent annually, leaving the country with an estimated deficit in energy production of 6 GW.

Punjab, the province in which the project is located, enjoys some of the highest solar irradiance in the world. With approximately 3000 hours of sunlight each year, the region is highly suitable for PV power generation. This project is located in an arid region where temperatures reach up to 50 degrees celcius during the summer. The extremely hot and dry climate demands the highest quality modules.

JA Solar supplied its modules under the supervision of PV Lab Germany GmbH, an authoritative third-party accredited laboratory which sets strict standards for raw material selection, manufacturing processes and quality inspection. JA Solar proved its reliability, high conversion efficiency and high power output by passing strict testing and shipping product on time. Tests included Electroluminescence Inspection and the 3×IEC Standard Thresher Test.

Mr. Yong Liu, Chief Operation Officer of JA Solar, commented, “The harsh and arid climate in Pakistan is a great challenge for our solar modules. Successfully shipping 100MW of our modules is a testament to the high quality and reliability of our products.”

Mr. Jian Xie, President of JA Solar, added, “The establishment of the Quaid-e-Azam Solar Park is an important means to attract foreign investment for Pakistan’s energy industry. By completing 100MW of shipments to Pakistan, JA has achieved a new milestone in its effort to expand globally into new markets. As a module supplier for the first large-scale solar farm in Pakistan, we proved that our cost-effective products will add significant value for our down-stream customers by increasing power generation and reducing installation costs.”

The Punjab Government announced its initial intention to establish a 700 MW solar park, but later increased its target to 1 GW.

New Technique from University of Toronto Offers Spray-On Solar Power

Pretty soon, powering your tablet could be as simple as wrapping it in cling wrap.

U of T researcher Illan Kramer

U of T researcher Illan Kramer

That’s Illan Kramer’s hope. Kramer and colleagues have just invented a new way to spray solar cells onto flexible surfaces using miniscule light-sensitive materials known as colloidal quantum dots (CQDs)—a major step toward making spray-on solar cells easy and cheap to manufacture.

“My dream is that one day you’ll have two technicians with Ghostbusters backpacks come to your house and spray your roof,” says Kramer, a post-doctoral fellow with The Edward S. Rogers Sr. Department of Electrical & Computer Engineering at the University of Toronto and IBM Canada’s Research and Development Centre.

Solar-sensitive CQDs printed onto a flexible film could be used to coat all kinds of weirdly shaped surfaces, from patio furniture to an airplane’s wing. A surface the size of your car’s roof wrapped with CQD-coated film would produce enough energy to power three 100-Watt light bulbs—or 24 compact fluorescents.

He calls his system sprayLD, a play on the manufacturing process called ALD, short for atomic layer deposition, in which materials are laid down on a surface one atom-thickness at a time.

Until now, it was only possible to incorporate light-sensitive CQDs onto surfaces through batch processing—an inefficient, slow and expensive assembly-line approach to chemical coating. SprayLD blasts a liquid containing CQDs directly onto flexible surfaces, such as film or plastic, like printing a newspaper by applying ink onto a roll of paper. This roll-to-roll coating method makes incorporating solar cells into existing manufacturing processes much simpler. In two recent papers in the journals Advanced Materials and Applied Physics Letters, Kramer showed that the sprayLD method can be used on flexible materials without any major loss in solar-cell efficiency.

Kramer built his sprayLD device using parts that are readily available and rather affordable—he sourced a spray nozzle used in steel mills to cool steel with a fine mist of water, and a few regular air brushes from an art store.

“This is something you can build in a Junkyard Wars fashion, which is basically how we did it,” says Kramer. “We think of this as a no-compromise solution for shifting from batch processing to roll-to-roll.”

“As quantum dot solar technology advances rapidly in performance, it’s important to determine how to scale them and make this new class of solar technologies manufacturable,” said Professor Ted Sargent, vice dean, research in the Faculty of Applied Science & Engineering at University of Toronto and Kramer’s supervisor. “We were thrilled when this attractively manufacturable spray-coating process also led to superior performance devices showing improved control and purity.

In a third paper in the journal ACS Nano, Kramer and his colleagues used IBM’s BlueGeneQ supercomputer to model how and why the sprayed CQDs perform just as well as—and in some cases better than—their batch-processed counterparts. This work was supported by the IBM Canada Research and Development Centre, and by King Abdullah University of Science and Technology.

Installing a solar hot water system presents its own unique set of challenges, and those inexperienced to SHW can get into trouble quickly by not following a few simple best practices.

Throughout recorded history humans used either fire or the sun to heat water. Some communities now have solar water in over 90% of their homes. SHW is often the “forgotten solar” among many professionals nowadays, as PV prices continue to fall and more people are drawn toward the appeal of generating their own electricity. Nonetheless, SHW represents the largest solar market on Earth, and is an affordable alternative to PV that is reliable, environmentally friendly and saves people money.

The average SHW system is the equivalent of a 2-kW PV system. Consumers qualify for the 30% tax credit and many utilities offer additional incentives on top of that. Utilities are traditionally friendlier toward SHW than its PV cousin, partially because SHW’s built-in storage helps reduce morning peak loads (especially in the winter months). SHW is generally viewed as the least costly way to reduce an electric bill. Depending on whether a family lives in a warmer or colder climate, systems range from $5,000 to $7,500, with full payback averaging four years.

Installing a SHW system presents its own unique set of challenges. Those inexperienced to SHW can get into trouble quickly by not following a few simple best practices. Some simple tips for quality installations are as follows:

  • You will need a well-rounded crew that is familiar with roofing, plumbing and light electrical work.
  • Whenever possible, mount the collectors in portrait orientation, not landscape. Most are designed with the risers inside running lengthwise allowing for easy draining and eliminating riser sag that can cause freeze damage. This is a critical mistake often made by new installers.
  • Do not mount too low down into the eaves area of the roof. This area is very difficult to reach from inside the attic space and can cause the installer to have to run plumbing lines outside of the house.
  • The tendency is to think of lowering the high limit on the differential controller. In reality, this is the opposite of what should be done, especially in warmer climates. SHW works very well, so the water coming out of the collector can be extremely hot. Raising the high limit keeps the water circulating, which reduces the chances of melting freeze valves or blowing pressure relief valves. A mixing valve or anti-scald valve should also be installed in these situations.
  • Install the appropriate kind of system for the region. There are several different kinds of SHW systems. Become familiar with words like active, passive, drain back and evacuated tube. Sometimes companies get caught up in using a single product for every application. This is completely wrong and can cause problems later. Always check with the local utility to see if they require a certain type of installation in to qualify for rebates.

The average residential system can be installed by two workers in about one day. Many contractors like these jobs because they are easier to finance, quick to install and can generally get paid the same day. Typically, your phone rings and the customer on the end states they “want to go solar.” Most of the time, this can be translated to “I want to save money.” SHW gives homeowners a less expensive alternative to PV. It reduces the homeowner’s utility bill by saving electricity versus creating it.

As solar has become more mainstream, new advances in technology are revolutionizing the industry. For instance, there are newer polymer collectors that prevent corrosion. Currently, there is movement toward PV-to-tank hot water systems that completely eliminate the SHW collector, something a solar electric contractor should find very appealing. If you’re strategizing new ways to grow your solar business and add to your existing product line, SHW may be the answer you’ve been seeking. SHW will not only help you gain new customers, it gives you another reliable product to go back and sell to your existing customers, helping them save even more money and further reduce carbon emissions. SPW

Equipment distributor Western Nevada Supply has added the APS microinverter line to its solar product offerings.

Known as “the Blue Team,” Western Nevada marked 50 years of local family ownership in 2014, and serves customers throughout the Nevada and California markets with an extensive line of solar, HVAC, irrigation, plumbing and industrial supplies.

“We’ve added the APS microinverter line to our solar offerings to expand our already strong lineup of solar products, and to offer our customers microinverter options in our northern Nevada and Eastern Sierra markets,” said Russ Cartwright, Solar Sales team member for Western Nevada.

Paul Barlock, APS America senior vice president, said the industry-leading APS microinverter brand is proud to be distributed by a company with such a strong history of family ownership and business success.

“Western Nevada is a great company and a great partner for APS,” Barlock said. “Given their geographic coverage, offering APS microinverters will give them a distinct competitive advantage in the Nevada solar market.”

Founded by Jack Reviglio and Bill Higgin, Western Nevada Supply opened shop in a rented 1,200 square-foot warehouse in Sparks, Nev., in 1964. From a modest beginning as a wholesale plumbing house, the business quickly grew, and in 1967 Jack’s brother, Tom Reviglio, joined the firm as marketer.

The company soon expanded with the addition of a waterworks sales department and relocated to a 7,000 square-foot facility. In 1973, strong growth again prompted a move, this time to a 10-acre site, which now has expanded to 20 acres with 40,000 square feet of inventory under one roof.

Today, a second generation of Reviglios run the family business. To better serve outlying areas, the company has opened branches in Elko, Carson City, and Winnemucca, Nev., and South Lake Tahoe, Bishop, Susanville and Truckee, Calif.

APS was founded in Silicon Valley in 2009, and is now a global leader in the development, manufacturing and marketing of microinverters based on their own proprietary, leading-edge solar technology. APS America, representing APS in the US market, is based near Seattle.

Recent major distribution deals have brought the APS line to the American Southwest, central California, mountain and mid-Atlantic solar markets.

United States Installs 1,354 MW of Solar in Q3 2014

$

Continuing its strong growth, the United States installed 1,354 megawatts (MW)  of solar photovoltaics (PV) in Q3 2014, up 41 percent over the same period last year. The numbers come from the latest edition of GTM Research and the Solar Energy Industries Association’s (SEIA) U.S. Solar Market Insight Report, released today. According to the report, Q3 was the nation’s second largest quarter ever for PV installations and brings the country’s cumulative solar PV capacity to 16.1 gigawatts (GW), with another 1.4 GW of concentrating solar power (CSP) capacity.

Solar is proving to be an important and growing source of new generating capacity for the United States. Through the first three quarters of the year, solar represents 36 percent of new capacity to come on-line, up from 29 percent in 2013 and 9.6 percent in 2012.

“Solar’s continued, impressive growth is due, in large part, to smart and effective public policies, such as the solar Investment Tax Credit (ITC), Net Energy Metering (NEM) and Renewable Portfolio Standards (RPS),” said Rhone Resch, SEIA president and CEO. “By any measurement, these policies are paying huge dividends for America. Every three minutes of every single day, the U.S. solar industry is flipping the switch on another completed solar project, benefitting both our economy and the environment.”

The report tracks installations across three market segments: utility-scale, residential and non-residential which includes commercial, government and non-profit installations.

type-of-installation

Historically, the U.S. utility-scale market segment has accounted for the majority of PV installations, and this past quarter continued the trend. The U.S. installed 825 MW of utility-scale projects, up from 540 MW in Q3 2013. This marks the sixth straight quarter in which utility-scale PV has accounted for more than 50 percent of the national total.

The U.S. residential market exceeded 300 MW in a quarter for the first time in history. Impressively, more than half of this total came online without any state incentive. Residential continues to be the most reliable market segment, now growing 18 out of the past 19 quarters. GTM Research forecasts it to exceed the non-residential segment in annual installations for the first time in more than a decade.

number-of-installations

“Residential solar has become a remarkably consistent, growing market” said Shayle Kann, Senior Vice President at GTM Research. “By the end of this year there will be more than 600,000 homes outfitted with solar, and we see no signs of a slowdown next year. By 2017, we expect the residential sector to be the largest in the U.S. solar market.”

The non-residential market continues its struggles of late, due in part to incentive depletion in California and Arizona. Installations in the segment were down 3 percent over Q3 2013. However, GTM Research and SEIA do expect year-over-year growth for the non-residential market.
The report forecasts the U.S. to install 6.5 GW of PV in 2014, a 36 percent increase over the historic 2013.

Key findings from the report:

•    The U.S. installed 1,354 MW  of solar PV in Q3 2014, up 41 percent over Q3 2013, making it the second-largest quarter for solar installations in the history of the market.
•    Cumulative operating PV capacity has now eclipsed the 16 GW mark, thanks to four consecutive quarters of more than 1 GW installed.
•    For the first time ever, more than 300 MW of residential PV came on-line in a single quarter and more than 50 percent of residential PV came online without any state incentive.
•    36 percent of all new electric generating capacity in the U.S. through the first three quarters of 2014 came from solar.
•    Growth remains driven primarily by the utility solar PV market, which installed 825 MW in Q3 2014, up from 540 MW in Q3 2013.
•    The report forecasts that PV installations will reach 6.5 GW in 2014, up 36 percent over 2013 and more than three times the market size of just three years ago.
•    Q1 2014 was the largest quarter ever for concentrating solar power (CSP), due to the completion of the 392 MW Ivanpah project and Genesis Solar project’s second 125 MWac phase. While no CSP plants came on-line in Q3 2014, Abengoa’s Mojave Solar (250 MW) achieved commercial operation in December 2014, making 2014 the biggest year ever for CSP.

The solar array will save Wildlife Associates enough to fund their programs to teach an additional 5,000 kids each year about wildlife and science.

Everybody Solar has announced that Mounting Systems, a leading manufacturer of solar racking systems, has donated a complete Alpha on-roof mounting system to the Wildlife Associates project in Half Moon Bay. The new racking system will help lower the cost of the 29 kW solar installation and brings the ‘Bring Solar to Wildlife’ crowdfunding campaign to 30% of the target.

Everybody Solar kickstarted a crowdsourcing campaign in September to raise funds for fellow nonprofit Wildlife Associates. Everybody Solar was seeking supply chain partners for material donations and Mounting Systems stepped forward to fill the gap and expedite the completion of the project. Previously, Enphase Energy came forward to donate inverters.

“We take community responsibility very seriously and are pleased to partner with nonprofits like Everybody Solar and Wildlife Associates who are doing valuable work,” said Don Massa, Product Manager at Mounting Systems. “Even though our Alpha racking system is quite easy and quick to install, it is a rugged, highly durable system that will provide years of trouble-free, reliable service for the Wildlife Associates Half Moon Bay Project,” said Massa.

“We’re honored to partner with Mounting Systems on the Wildlife Associates installation,” says Youness Scally, Executive Director of Everybody Solar. “Wildlife Associates spends thousands of dollars annually on energy bills to care for over 50 wild animals or ‘teachers’ at the Half Moon Bay sanctuary. These wild animals and staff travel to over 300 local schools each year to teach kids about wildlife conservation and environmental awareness. With Mounting Systems’ support, we can defray 90% of the sanctuary’s electricity costs and enable Wildlife Associates to care for three additional wild animals.”

The solar array will save Wildlife Associates enough to fund their programs to teach an additional 5,000 kids each year about wildlife and science.

Parker Offers “Smart Cylinders” Integrate with Position Sensor for Solar Tracking

$

Parker Intellinder ImageParker Hannifin, motion and control technology specialist, is bringing new “smart cylinders” to the power generation market, featuring its “absolute position” Intellinder actuation sensor. Intellinder is a combination of a positional bar code pattern, etched on the cylinder’s piston rod, and a highly engineered optic reader. With resolution of up to 0.001” (0.03 mm) and speeds to 40 inches/sec, (1 meter/sec) integral health monitoring and the ease to incorporate true redundancy, Intellinder provides Power Gen engineers a superior alternative to their position monitoring needs. Intellinder-enabled cylinders include hydraulic, pneumatic and electro-mechanical designs that are rugged, and engineered to sustain performance in solar panel tracking.

By integrating a highly engineered sensor directly into the hydraulic, pneumatic or electromechanical actuator, this Parker innovation eliminates the time and cost associated with gun drilling, as well as unprotected external sensors with complex linkages. Cylinder feedback installation is virtually plug-and-play.

“The Intellinder sensor brings a unique competitive advantage to all of Parker’s cylinders,” said Bruce Besch, Advanced Motion Products Manager for Parker’s Industrial Cylinder Division. Besch explains, “ Standard positioning technologies rely on magnetostrictive sensors, variable resistance sensors (string pots) and laser gauges. These all have limitations, including short strokes, dead zones, calibration needs, water ingression, temperature range restrictions, interference from contaminants, annoying electrical noise and time-consuming removal and repair. These problems all add inefficiencies to power gen operations, which increases operational cost. Parker Intellinder-enabled cylinders eliminate these issues and streamline operations.”

The Intellinder Sensor signals absolute positioning, rather than position relative to the starting location of the rod. A position identifying bar code pattern is etched directly onto standard rods, with no alterations required to the cylinder’s piston, head or cap. The optic reader bolts to the cylinder head, and the position is communicated continually and directly to the controller. Position reporting occurs at power-on and does not require calibration. Parker’s design allows for full utilization of even double-rod cylinder applications, allowing customer utilization of both rod ends.
– More –

Intellinder feedback devices utilize serial bus connectivity, so multiple Intellinder cylinders can be networked together with a single cable back to the host controller. True redundancy is achieved by simply adding multiple, non-contacting reader sensors to the cylinder. Long cables up to 300 feet (90 meters) from the farthest cylinder to the output module, may be used. Analog output modules are protected to IP67 and do not need to be mounted in enclosures.
Intellinder-enabled cylinders include hydraulic, pneumatic and electro-mechanical designs that are rugged, and engineered to sustain performance in harsh environment power gen actuation applications, including hydroelectric plant and dams, gas turbines, wind turbine rotors and solar panel tracking. Intellinder-enabled cylinder and actuation system features and benefits include:
• Environmental:
o Extreme operating temperature rating (-40o to 221o F, 40 to 105 C)
o Sustains performance in applications exposed to vibration, dust, gravel, corrosives, chemicals, axial load, side load, and immersion
o Remains impervious to electronic noise and has been tested to ensure signal strength in the most rigorous applications.
• Construction:
o Steel and stainless construction available as NFPA tie rod or round line design
o Universal across a wide range of cylinder bore and rod diameters, with stroke lengths up to 20 feet (6 meters)
o Multiple Intellinder-enabled cylinders can be connected to a single bus, offering reduced installation and commissioning costs — Installation is virtually plug-and-play
• Intellinder sensor : Exterior mount, non-pressurized, non-contacting sensor that is easy to replace
• CAN communication to signal conditioning electronics allow long cable runs
