Técnico de CENER en una instalación de Soltec / CENER technician in a solar plant of Soltec

The Photovoltaic Components Testing Laboratory of CENER (National Renewable Energy Centre of Spain), has obtained the ENAC accreditation for carrying out the tests on solar trackers according to the IEC 62817: 2014 standard. This milestone makes CENER the first and only one laboratory in Spain to be accredited by the spanish national accreditation entity ENAC to carry out this activity.

Solar trackers are a key element when trying to obtain the maximum level of electric generation in photovoltaic solar energy installations, and they are a critical component in concentrating photovoltaic technology systems. Solar trackers can provide an optimal orientation for photovoltaic modules, increasing the level of power generation for flat technology modules between 20% and 45% with respect to fixed tilted PV installations, depending on the type of tracking.

For this purpose, the international standard IEC 62817:2014 contains procedures to measure and verify the parameters indicated in the technical data sheet of the solar tracker. This standard establishes the acceptance and rejection criteria for the results of the tests to be carried out, and subsequently according to these results, it is possible to qualify the product. The IEC 62817:2014 standard contains, among others, climatic tests (thermal cycling tests, humidity-freeze cycles, etc.); operating tests (accelerated cycles, operation with the presence of dust, etc.); mechanical tests (wind loading, backlash, deflection, etc.); characterization of the consumption of the tracker and the precision of the tracking system, and, finally, specific testing of the tracker electronic component.

The application of the IEC standard offers the guarantee that parameters presented in the solar tracker data sheet are measured and verified by consistent and reliable procedures. At the same time this information can be used to compare the characteristics of different solar trackers.

Researchers from the Department of Photovoltaic Solar Energy of CENER have developed their own methodology based on the IEC 62817:2014 standard, implementing the test sequences and grouping them, with the aim of reducing the number of samples needed, as well as the movements of the heaviest pieces, to optimize in this way the total duration of the tests. The methodology developed has been disseminated in technical publications and international congresses, having finally obtained accreditation from ENAC.

On Tuesday 11 December, Aremur, the Renewable Energy and Energy Saving Business Association of Murcia held the first seminars in the Region of Murcia on large PV projects with the collaboration of the Regional Federation of Metal Companies of Murcia (FREMM) and Soltec, Europe’s largest solar tracker manufacturer. Entitled “Solar Plants in the Region of Murcia”, the leading players in the PV sector came together in the FREMM conference hall. The event was inaugurated by Javier Celdrán, Minister for Employment and the Environment, José Marín, Chairman of Aremur and Raúl Morales, CEO of Soltec, and involved three round table discussions which addressed the most important aspects of the implementation process of a PV plant.

After the opening introduction, Esther Marín, General Manager of Energía y Actividad Industrial y Minera, gave a presentation on the future of PV energy.

Iberdrola and REE, the Spanish electrical grid, gave their perspective on the new regulation on access and electricity connection. There was also a round table discussion on administrative matters regarding the authorisation for implementing PV plants in the Autonomous Community of Murcia.
Lastly, the event addressed the technical aspects of designing a utility-scale solar plant, as well as the advances and innovations on the subject, with contributions from JinkoSolar, Power Electronics and Soltec.

Soltec is currently constructing a 84.7 MW solar plant in the Region of Murcia. As part of the project’s corporate social responsibility actions, the company has signed a collaboration agreement with the Totana Town Hall through which they have undertaken to employ people with intellectual disabilities. In this way, users of the “Princess Letizia” Day Centre for People with Mental Illness and the “José Moyá” Day Centre for People with Intellectual Disability will be responsible for the pre-assembly of the screws destined for this PV plant.

The agreement, signed by the mayor of Totana, Andrés García Cánovas, the regional manager of Soltec in Spain, Luis Hernández, and by Ana García Vera, director of the José Moyá Centre, will provide the users of this centre with technical training in the pre-assembly of the screws, thereby fostering their personal and professional development.

In total, 2,900 units of the SF7 single-axis solar tracker will be installed in this plant that will make use of the region’s high level of solar irradiation. Once operational, the plant will avoid the emission into the atmosphere of 63,000 tonnes of CO2 a year, the equivalent to that produced by 15,000 vehicles.

Soltec’s global operations and a workforce of over 750 people bring together experience and innovation. The company has manufacturing centres in Brazil, China and Spain; and offices in Australia, Denmark, Chile, Egypt, the US, India, Israel, Italy, Mexico and Peru. Firmly committed to renewable energies and the environment, Soltec supports product standardisation and the success of its clients.

European multinational PVH (PVHardware), manufacturer of solar trackers and structures for PV plants, has focused its efforts during the last years in developing its technology to adapt it to extreme weather conditions. After its latest projects in Jordan, Egypt and the United Arab Emirates, the company has specialized in desert projects, where strong wind can be an adversity. Because of this, it was important to reduce the stow position time of the trackers as far as possible, to better protect the panels from this type of weather and to prevent possible damage.

The time to stow position is decisive to prevent harm on the structures and to avoid aeroelastic instability incidents known as fluttering. The importance of this is even higher in projects located in desert areas, where wind speed suddenly changes in a matter of minutes. In addition, during the last two years PVH’s R&D department has focused on wind tunnel tests, which allow to strengthen even further the protection against climate factors. While the trackers by other providers usually take around twenty minutes to adopt stow position, Monoline is able to make it in fifty seconds.

The value of a clever alarm system

One of the main factors to achieve this progress is the alarm system designed by the company, which includes four pre-configured levels in relation to wind speed. Thanks to this clever system, the tracker is always as close as possible to the stow position, and is able to reduce Monoline‘s standard five minutes to fifty seconds. The other key element is the motor used by this solar tracker, which is notable because of its superior power and quality, and allows for a high-level performance with a minimal number of actuators.

The Monoline technology was first launched in 2015 in El Salvador, and is currently present in thirteen photovoltaic plants in Central America, United States, Mexico and Australia. It has also been successfully used at the Benban PV project in Egypt, where PVH is installing 800 MW with different versions of Monoline.

PVH is a provider of innovative solar tracking solutions for the global utility-scale solar market, including trackers, fixed structures and SCADA system. The company has an annual production capacity of 3.5 GW.

The company supplies solar trackers to two PV plants in the Brazilian state of Minas Gerais

Soltec has started to supply its trackers to two PV plants in the state of Minas Gerais, in south-east Brazil.

The municipality of Guimarânia will be home to approximately 2,800 SF7 Single-Axis Trackers that will be installed at one of the two solar plants. Soltec’s trackers will move nearly 250,000 PV modules to track the sun’s position in the sky for increased annual energy capture.

Project developer, Canadian Solar, EPC company Biosar and utility Global Power Generation (GPG) have teamed up with Soltec for this 82.5 MW project in Guimarânia. The plant is currently under construction and is scheduled to be operational by the end of December 2018.

At the same time, Soltec is also supplying its SF7 self-powered trackers to one of the largest distributed generation solar power plants in Brazil. Located in the municipality of Uberlândia, this plant will enter into operation this month.

Alsol Energias Renováveis, whose activity comprise developing renewable energy projects for companies and private individuals, chose Soltec’s trackers and the reliability of its supply for this 5 MW PV plant.

“Customers know that our experience and leading position as solar tracker supplier in Brazil make Soltec a safe bet”, says Raúl Morales, CEO of Soltec. “Soltec’s market leadership in the country has already been clearly demonstrated and is largely due to our ability to supply equipment at an astonishing rate”.

In order to cover the costs of the company’s commercial expansion that started in 2014, the year in which it launched its international trajectory by signing its first supply contract for a utility-scale solar plant, Soltec has agreed a loan for 100 million Euros in order to continue with an internationalisation process that has enabled the company to undertake projects and open subsidiaries on the five continents.

The financing has been headed up by Banco Santander, with consultation from PwC, and has involved Spain’s leading financial entities: Bankia, Bankinter, BBVA, Caixabank, Cajamar CajaRural, Ibercaja, Liberbank, Sadabell, Banco Cooperativo Español and Banco Pichincha España. Throughout the entire process Soltec has benefitted from the collaboration of Garrigues on legal matters.

Syndicated loans are a special financing method, defined by the joint intervention of several credit institutions that agree to authorise a loan which, due to its high amount, requires the cooperation of several financial institutions.

“We are grateful for the confidence that these financial entities have placed in us,” comments Morales. “This loan will allow us to continue supplying solar trackers to the increasing number of PV projects in which Soltec is involved in countries as diverse as Brazil, Egypt and Spain”.

Soltec’s global operations and a workforce of over 750 people bring together experience and innovation. Soltec has manufacturing centres in Brazil, China and Spain; and offices in Australia, Denmark, Chile, Egypt, the US, India, Israel, Italy, Mexico and Peru.

With a firm commitment to renewable energies and the environment, Soltec supports product standardisation and the success of its clients.

Soltec has started supplying and installing its equipment at an 84.7 MW solar PV power plant in Spain. Other such projects are on the near horizon. The European Union’s clean energy directive sets a binding target of 20 percent final power consumption from renewable sources by 2020, and Spain will comply or exceed.

Located in the Region of Murcia in Southeast Spain, the PV power plant will benefit from high solar irradiation and optimal climate conditions. Adding value to the project are Soltec’s headquarters and the Solhub logistics center within a few miles of the construction site. Around 2,900 units of Soltec’s SF7 seventh generation horizontal single-axis solar tracker will be supplied.

Corporate Social Responsibility is having an important role in this project. Soltec is training local people for employment in construction, and disabled persons will carry out appropriate tasks. Underground offtake cabling and a wildlife corridor are incorporated to reduce environmental impact in addition to standard SF7 features that reduce earth grading, earth penetrations, and emissions during construction.

CEO of Soltec Raúl Morales explains: “Our standard tracker features reduce material and installation time compared to others. SF7 has fewer piles-per-MW, a lower parts count, fewer installation operations, and greater tolerance of construction variables among other advantages. The combined result of higher yield performance and robust design is what customers rely on when choosing us.”

PVH structures and trackers have proven strong enough to resist against a natural disaster such as Hurricane Florence, which caused many fatalities in September in the Carolina states (USA). The IS31 PV plant, located in North Carolina, has a capacity of 43.2 MWp and uses Monoline single axis solar trackers by PVH. Hurricane Florence reached Category 4 strength in the same area, with estimated maximum sustained winds of 140 mph, causing the tragic death of at least 45 persons and $38 billion in damage. Under these circumstances, an incident at the IS31 plant could have also been very dangerous and disastrous, but thanks to the solid structure of PVH’s trackers it turned out to be the opposite: all workers in the plant are safe, and energy production has not been interrupted.

PVH has always taken safety and reliability very seriously for its products, and has performed strict wind tunnel testings in universities in Ontario and Madrid for years. As a result, PVH structures are prepared for minimizing aeroelastic instability incidents known as “fluttering”, which are more likely to occur when the wind is strong, and to withstand natural phenomena such as this one.

In addition, PVH’s engineers always analyze the terrain and climatology of each area in depth, in order to adapt the foundations and materials to the needs of each solar plant. Taking all this into account, and despite the inevitable concern caused by a natural disaster like this, PVH’s personnel always had full confidence in the resistance of the IS31 plant and its structure, and knew that the energy production would not be affected. Furthermore, the maintenance costs caused by this event have been minimal, and workers have safely resumed activity.

A typhoon in the Philippines

In the Philippines, the Typhoon Mangkhut (also known as Typhoon Ompong) has been even more devastating this same month. It caused its main damage in the northern part of the country, but it could also be felt at the Leyte photovoltaic plant, where PVH provided fixed tilt structure. Everybody working in this plant is also safe, and the solar structure has not suffered any damage. It is not the first time that the Leyte plant has faced this kind of adversities, because the typhoon season takes place every year in the Philippines around this time, to a greater or lesser extent.

Structures and trackers by PVH are capable of adapting to the most complicated locations and overcoming extreme conditions, offering efficient and profitable long-term solutions for every situation. From strong winds, and damp and saline environments, to the sand, dust and high temperatures of the desert.

Soltec, a leading manufacturer and supplier of single-axis solar trackers and related services in large ground-mount PV projects, presents Dy-WIND, an innovative method for comprehensive dynamic analysis in tracker wind-design. Soltec has decided to undertake this project after several studies have shown that certain wind-design code standards applied to solar trackers are insufficient to design these structures reliably, as they do not consider the second order effects produced by the action of wind on the tracker.

Conventional wind tunnels use rigid models that do not consider fluid-structure interaction effects such as the aeroelastic response of the structure. These phenomena cause instabilities (torsional galloping/flutter) that can produce the collapse of the trackers. The structure and its components must be designed stiffer and more robust than only applying the unsafe and incomplete current wind regulations and standards.

Only Soltec applies Dy-WIND analysis to tracker wind-design for accurate modeling that leads to precise manufacturing processes,” declared Raúl Morales, CEO of Soltec. “This is essential to making economic calculations regarding the profitability and robustness of a solar tracker plant.

With Dy-WIND, two types of wind tunnel tests are carried out to obtain the necessary aerodynamic parameters of scale models and precious results for the implementation of calculation methods that provide a realistic response of the behavior of solar trackers under the action of the wind.

  • Wind tunnel pressure tests: Static Wind Loading Coefficients are combined with Dynamic Amplification Factors (DAF) to cover the design wind speed ranges, considering the airflow wake behind each row.
  • Wind tunnel dynamic tests: Aerodynamic derivatives obtained allow accurate knowledge of the tracker’s response to wind action. Such parameters are combined with numerical models to obtain Fluttering and Buffeting Analysis Methods.

To develop Dy-WIND, Soltec has teamed up with the renowned engineering consultancy Rowan Williams Davies & Irwin Inc (RWDI), which specializes in wind engineering projects. Matthew T. L. Browne, Technical Director at RWDI, said: “the hybrid experimental-numerical approach developed through working with Soltec accurately estimates tracker behavior under the action of wind in multi-row arrays and allows flexibility in the design process that is generally not practical through full aeroelastic model testing.”

RWDI already has the expertise and wind tunnels that use stereolithography technology, integrated data acquisition, storage and processing systems, computer-aided drafting and a broad base of specialized instrumentation. Some of the most notable projects in which the firm has participated are the Petronas Towers in Malaysia, the Burj Khalifa skyscraper in Dubai or the Messina Strait Bridge in Italy.

Soltec’s global operations and workforce of over 750 people blend experience with innovation. The company has manufacturing facilities in Argentina, Brazil, China, and Spain, as well as offices in Australia, Chile, Denmark, Egypt, India, Israel, Italy, Mexico, Peru, and the United States. With a strong commitment to renewable energy and the environment, the company is dedicated to innovation, product standardization, and customer success.

Dy-WIND takes its place in the extensive list of Soltec historic innovations made standard features that have resulted in the next-generation-now SF7 solar PV tracker whose mission is to find lower cost electricity for customers within their challenging tracker projects.
