PV inverters

Ingeteam has recently signed a number of contracts for the supply of PV plants to Mexico, a country in which the company has a considerable market share in the wind and solar power sectors, and in the provision of operation and maintenance services for power generation plants.

The company, which has been present in this country since 1998, is to supply 555MW of solar PV inverters, mostly directed at large solar plants, although part of the supply is for commercial plants based on string inverters.

Most of the supply corresponds to the Skid series for Ingeteam’s Inverter Station, comprising a metal platform or skid holding all the low and medium voltage devices required (LV/MV transformer, MV cells, LV switchgear and auxiliary services transformer), in addition to the central inverters pertaining to the INGECON SUN PowerMax B series. This equipment has a total output power of 551MW and is to be supplied to four photovoltaic plants located in the states of Baja California, Durango, Sonora and San Luis Poltosí. The supply comprises a total of 343 central photovoltaic inverters, all with the very latest 1500Vdc technology.

One of these three projects represents the first PPA (Power Purchase Agreement) in Mexico between a private generator and the end user.

Moreover, Ingeteam has recently commissioned two solar plants with a total output power of more than 60MW in the state of Chihuahua. These plants have also been equipped with the Inverter Station solution with 1500Vdc photovoltaic inverters.

These new contracts serve to strengthen Ingeteam’s position in Mexico, where it is the leading company in the supply of power converters (with 2.5GW for wind and solar PV plants). It is also the leading provider of operation and maintenance services with 2.5GW of maintained renewable power, which means that the company is responsible for the maintenance of 49% of the total installed power in Mexico.
This leadership has been consolidated in the last year thanks to several important operation and maintenance contracts, like the one for the 35.5 MWp Camargo PV plant, located in the state of Chihuahua. Thanks to these contracts, Ingeteam maintains 55% of the total solar power installed in the country.

Furthermore, Ingeteam was recently awarded a supply contract for Latin America’s largest PV plant. Thanks to this contract, Villanueva solar park’s electric substations have been equipped with a highly advanced automation system, thanks to which Ingeteam has reached the figure of more than 2,000 MW of substations for renewable energy plants digitalized in Mexico. Thus, Ingeteam consolidates itself as a benchmark for grid digitalization in a double manner: first, through digital electronics in PC&M systems for substations automation; and second thanks to its reactive energy compensation systems (Statcom) for grid code compliance in renewable and industrial installations.

Several offices in the country

In Mexico, Ingeteam has several offices dedicated to different activities. In the country’s capital city –Mexico City- and in Juchitán de Zaragoza –Oaxaca-, two Ingeteam offices are dedicated to wind and solar O&M works, PV inverter commercialization, development of substations for renewable energy plants and distribution of equipment and execution of projects for the protection and automation of the electric grid.

Moreover, the Company develops an important social role in the regions where it is present. For example, Ingeteam implements some renewable energy diffusion projects in the region of the Tehuantepec isthmus, in order to spread the knowledge about renewable energies among the communities, contributing to a deeper understanding of these relatively new technologies.

The global solar PV inverters market will decline from $6.3bn in 2017 to $3.7bn in 2022, with Asia-Pacific (APAC) relinquishing its leading regional share to the Americas over the forecast period, according to GlobalData. The company’s report: ‘Solar PV Inverters – Update 2018’ states that solar PV inverters will hold an aggregate global market value of $22.2bn between 2018 and 2022, with an average annual value of $4.4bn during the same period.

In terms of solar PV additions, APAC eclipsed all other markets for the fourth consecutive year, accounting for about two-thirds of global additions in 2017. Consequently, the APAC region led the solar inverters market, with a value of $3.75bn. It was followed by Americas and EMEA (Europe, Middle East, and Africa) registering $1.71bn and $0.89bn, respectively.

However, APAC will see its share of the market fall from 59% in 2017 to 38% in 2022, while the solar PV inverter market share for the Americas will expand from 27% to 41% over the same period. EMEA’s share will increase from 14% to 21% between 2017 and 2022.

In terms of market value, China, the US, and Japan together held over 65% and led the global solar PV inverter market in the year 2017. The market developments in the top countries are largely due to economies of scale, emerging inverter technologies, and policy-based government and institutional industry.

Between 2017 and 2022, the global solar PV inverters market is expected to witness a negative compound annual growth rate (CAGR) of 10.15%, in terms of market value. The estimated fall in the market value is mainly attributed to the fall in inverter prices.

The solar inverter and module prices have declined for a variety of reasons, including but not limited to, persistent price pressure on equipment suppliers, the anti-dumping tariffs implemented by the US on Chinese modules, the euro and yen depreciation, and the downward adjustment of the minimum import prices. In the solar PV industry, buyers are price sensitive, creating persistent price pressure on equipment suppliers.

The global solar PV inverters market has several strong participants such as Huawei Technologies Co Ltd, Sungrow Power Supply Co Ltd, and SMA Solar Technology AG. The highly fragmented nature of the market has also led to the reduction in solar inverter prices. As a result of the falling prices, the total installed capacity between 2018 and 2022 is estimated to be close to 370.6 GW, whereas it stood at approximately 316.2 GW between 2012 and 2017.

According to GTM Research’s latest report, The Global PV Inverter and MLPE Landscape 2016, global shipments of solar PV inverters will reach 90 GW (AC) by 2020. This represents an average annual growth rate of 11 percent between 2016 and 2020.

Of the 59.7 GW shipped in 2015, 66 percent were in the Asia-Pacific region, led by China and Japan. With the impending decline of the Japanese market, the report notes that demand will shift to other regions including Latin America, India, the Middle East and Africa. By 2020, GTM Research forecasts the Asia-Pacific region to account for less than half of all inverter shipments.

In spite of the promising long-term outlook, growth will be flat in 2016. “Due to the U.S. utility solar ITC rush and strong demand in China, there was a buildup of shipments in 2015 to meet 2016 project demand” said report author and GTM Research analyst Scott Moskowitz. “Overall installation growth will slow in 2017, resulting in flat inverter shipments year-over-year.”

The report ranks and profiles leading PV inverter manufacturers. For the first time ever, Huawei took the top spot in terms of shipments according to 2015 figures. Sungrow, SMA, ABB and TMEIC rounded out the top five.

The report also highlights the fundamental shift in inverter technology preferences. In 2015, central inverters accounted for 57 percent of all inverter shipments, but with the continued rise of three-phase string inverters, central inverters will see its share fall to 43 percent by 2020. Module-level power electronics will additionally gain share as their prices fall and use expands to commercial markets. MLPE are expected to account for 10 percent of all inverter shipments by 2020.

Inverter pricing continues to steadily declining as the market grows and technology advancements enable lower costs. The report points to 1,500-volt inverter technology, higher power density string inverters and rapidly falling microinverter pricing as key drivers for the overall downward pricing trend. GTM Research forecasts inverter prices to decline 10 to 12 percent annually across most product segments through 2020.

By 2020, the global PV inverter market will value more than $7.1 billion.
