    Ingeteam has revamped the equipment of the solar PV plant of Campillos, Málaga. Specifically nine aged units have been replaced with Ingeteam’s INGECON SUN 100TL inverters in order to avoid losses due to equipment availability, while extending the useful life of the plant.

    This activity is in line with Sonnedix’s strategy as a long-term asset owner, managing and investing in guaranteeing the operational excellence of its plants. The new inverter model will improve the availability of the equipment, and thus the solar PV plant, and ensure the plant performs to its expected level.

    This PV plant was inaugurated in 2008, the first one set up in the province of Málaga and owned by Sonnedix, occupying an area of 6.8 hectares, equivalent to approximately 7 football fields, and generating energy for some 3,000 homes per year.

    The operation lasted 4 weeks and consisted in deploying nine INGECON SUN inverters of 100kWac. The main characteristic of this equipment is that they can deliver the nominal power up to 50ºC of ambient temperature. In addition, its high MPP voltage range (maximum power point), from 513 to 850 V, allows it to extract the expected performance of solar panels. Furthermore, these inverters integrate Wi-Fi communication as standard, facilitating and speeding up the work of local and remote monitoring.

    The replacement of inverters has also included the reconfiguration of the strings of the photovoltaic plant in order to accommodate for the new MPPT operating window of the inverters while maintaining the original installed peak power.

    At present, Ingeteam has several projects to improve and optimize photovoltaic plants that, due to the lack of performance, the disappearance of the manufacturers or the lack of after-sales service in Spain, has resulted in owners trusting the service and the consolidated product line of Ingeteam.

    The global solar market is booming, and the Chinese inverter exports reach a record level in 2019 H1. According to the data of China Customs, Huawei exported 113,086 inverters in the first half of the year and ranked No.1 among the Chinese inverter manufacturers.

    Growatt came after Huawei in the second place with 86,153 inverter exports, and Ginlong Solis in the third place with 78,114 inverter exports. GoodWe, Sungrow, SofarSolar and SolaX follow in the inverter export ranking. As shown in below chart, Huawei, Growatt, Solis and GoodWe are among the Tier 1 inverter manufacturers that have exported over 70,000 inverters.

    Strong exports to Europe

    The strong growth of Netherlands PV market has absorbed a large number of the Chinese inverter exports. Growatt shipped 43,487 inverters to Netherlands in the first half of 2019 and Huawei shipped 34,230, GoodWe 29,233, Solis 6,228, Sungrow 3,550 and SofarSolar 8,849, respectively.


    The renewable energy sector in UK is observed with growth momentum, which benefits Solis and SolarX. Overall, the Chinese inverter manufacturers exported to key European solar markets, Netherlands, Italy, UK, Belgium and Poland; all of them are markets with good potential.

    Impressive growth in Australia and Americas

    Apart from Europe, Chinese inverter manufacturers had their eyes on Australia. In Australia, Solis, Growatt, GoodWe and SolaX have taken a good pie of the market, all exporting over 10,000 inverters to the region.

    Australia started encouraging the development of solar energy back in 2001, the same time when China stepped in to promote the growth of the industry. In 2009, Australia put forward with the feed-in tariffs policy and by the end of 2018, the country had installed a total capacity of over 11 GW. Its residential sector is expected to reach installed capacity of over 10 GW. Besides abundant solar resources, Australian market has many favorable conditions for the development of distributed PV generation with most Australian households living in independent houses or villas and a great number of independent public and commercial facilities.

    In Americas, Argentina, Brazil and Mexico are the main destination of Chinese inverter exports. The growing Mexican solar market has imported a good number of inverters from Growatt, GoodWe and Solis. Brazil has also seen strong competition of the Chinese inverter brands. The US tariff on Chinese modules has affected the Chinese exports, but the Chinese manufacturers have quickly adjusted to the impact and turned to Latin America for growth.

    ABB and the Italian company Fimer S.p.A announced today that they have signed an agreement for Fimer to acquire ABB’s solar inverter business. The transaction will enhance the future prospects of the solar inverter business and will enable ABB to focus its business portfolio on other growth markets.


    ABB’s solar inverter business has approximately 800 employees in more than 30 countries, with manufacturing and R&D sites located in Italy, India and Finland. It includes the solar inverter business from Power-One which was acquired by ABB’s Discrete Automation and Motion division in 2013.

    The business offers a comprehensive portfolio of products, systems, and services for different types of solar installations. It is currently within ABB’s Electrification business and achieved revenues of approximately $290 M$ in 2018.

    Both companies will ensure a smooth transition for customers and employees. FIMER will honor all existing warranties and ABB will compensate Fimer for taking the business and its liabilities over. As a result, ABB expects to take an after-tax non-operational charge of approximately 430 M$ in the second quarter of 2019 with the half-year results of 2019 being impacted accordingly. Around 75 percent of this charge is represented by cash outflows ABB will pay to Fimer from the deal closing date through 2025. In addition, ABB expects up to 40 M$ of carve-out related separation costs starting in the second half of 2019.

    After closing of the transaction, ABB expects the operational EBITA margin for the Electrification business to be impacted positively by slightly more than 50 basis points, supporting the business’ progress towards its target margin corridor of 15-19%.

    Completion is expected in the first quarter of 2020 and will be subject to certain conditions, including the completion of the carve-out and prior consultation with employee representative bodies.

    The GoodWe inverters have been installed this year on a large 1MW project in the city of Buenos Aires, the capital of Argentina. The purpose of this project is to provide clean electricity from solar to an approximate of 1000 new house units, involving as well thermal and water pumping. This installation is part of a large urban improvement project in one historical neighborhood of low income of the Argentinian capital.

    Due to a proved record of successful installations all over the world, the GoodWe proposal, consistent on more than 100 pieces of DT inverters of 10kW (suitable for use on commercial) were selected as the best choice in a fierce competition by one of the most reputed Argentinian EPC companies. This project is now owned by the city government and it was partly funded by large international organizations that typically have an extremely demanding criteria for the selection of suppliers. According to Wood Mackenzie, last year GoodWe became the 7th largest PV inverter supplier in the world, making the company a powerful candidate for this kind of projects.

    GoodWe has accumulated a rich experience in projects aimed at alleviating poverty in isolated communities of China, in which the company inverters help local dwellers generate the electricity they consume and have additional income from the sale of surplus to the grid. This Argentinian project is technically different but it has the common element that solar is also a practical tool for raising the living standards of the population and in the process, making urban spaces more livable.

    The area of the installation is located at a historical part of Buenos Aires where the population used to live in crowded spaces. It was not rare to see in this region illegal plugging into the grid, creating a significant burden for the local government. Thanks to the better housing that is being constructed along with these brand new GoodWe solar installations, the situation is starting to improve, allowing the inhabitants of that neighborhood to generate a large portion of the electricity they need. This project is a sort of pilot program that has the potential to be replicated in other countries.

    The GoodWe DT model is an inverter specially designed for use on commercial and industrial rooftops but it is deployable in residential projects. The majority of the DT models installed on this project are of 10kWs capacity and the reasons behind their selection in Argentina have to do with their low weight, which is 30% lighter than equivalent products from competitors, and the high efficiency they can reach. The customer has also reported been impressed by the GoodWe’s SEMS monitoring system that allows operators to see in an accurate manner the power generated by the system.

    Another happy aspect of this project is the fact that it is based in Argentina, a country that has experienced a remarkable growth in the demand for solar energy over the past years, consolidating its ranking as the fourth largest PV market in Latin America. The energy industry of Argentina has undergone profound adjustments which have encompassed the approval of new regulations that incentivize the expansion of solar. For GoodWe, Argentina has become a strategic market and the company remains committed to preserve the trust gained and to keep expanding the brand across the vast Latin American region.

    Fronius has carried out a very special project in Zwentendorf, Austria: a photovoltaic system has been installed on the site of a former nuclear power plant (NPP)

    Where once nuclear energy was to be produced, today clean, safe energy is generated from natural resources over an area of 3,700 square metres. The project reflects the Fronius vision of 24 hours of sun; a world in which all our energy needs are satisfied through renewable sources.

    In April 1972 the ground-breaking ceremony for Austria’s first nuclear power plant took place in Zwentendorf an der Donau. Six years later however, a referendum prevented the completed and ready-for-use nuclear power plant from being put into operation. Since 2005 the land has been owned by the energy supplier EVN, who in 2012 built a photovoltaic system on the site.


    Fronius provides the right solar technology

    The available space and existing infrastructure of the nuclear power station provided the perfect conditions for building a photovoltaic system. A total of 1,000 photovoltaic panels affixed to the façade, roof and the surrounding area of the old power plant constitute an area of 3,700 square metres of clean energy. Fronius Solar Energy provided the necessary solar technology for this. The direct current generated by the solar panels is converted into alternating current by 43 Fronius IG Plus inverters and fed into the public grid.
