25 MW Supply Contract Signed: ADLER Solar and Hanwha Q CELLS Repower Older PV Systems

  • Hanwha Q CELLS supplies 25 MW Q.PLUS solar modules with Q.ANTUM technology for repowering projects to ADLER Solar; with the option to upgrade to 30 MW
  • ADLER Solar offers comprehensive repowering solutions from one source,
    Hanwha Q CELLS provides highly efficient solar modules with Q.ANTUM technology
  • For older PV systems suffering from yield loss, repowering measures with quality­ components are economically attractive for system operators, banks and investors

Hanwha Q CELLS GmbH and ADLER Solar Services GmbH have concluded a supply contract for 25 MW high efficiency Q.PLUS solar modules of the Q CELLS brand with integrated Q.ANTUM technology, with the option to upgrade to an additional 5 MW. The German subsidiary of the world’s largest solar cell manufacturer Hanwha Q CELLS Co. Ltd (NASDAQ: HQCL), and the leading full service provider for the solar industry, ADLER Solar, are entering a long-term partnership with the goal to repower older PV systems. This business model is profitable for commercial/industrial PV system operators and banks or investors alike, whose solar systems are falling short of economic expectations due to an increasing drop in performance. Repowering measures restore the original nominal power of ground mounted and roof top installations, compensate profit loss and maximise feed-in tariffs. In order to avoid future recurrences, high efficient solar modules of the Q CELLS brand are installed.

Repowering means faster return on investment

“The repowering method is an extremely attractive solution for PV system operators, banks or investors alike, whose solar system show a progressive degradation“, says Michael Reck, Head of Repowering at ADLER Solar. “Repowering clients expect continuous high quality standards: Starting with the concept, through the components used, all the way to the implementation of the appropriate measures”, Recks states further. “Quality and high performance are top priorities of ADLER Solar for each repowering project and this is why we are thrilled to have found a competent module partner in Hanwha Q CELLS, internationally recognized for the extraordinary performance and reliability of their solar modules.“

“The large number of solar systems for which repowering measures would pay off are impressive evidence that it is worthwhile to invest in quality modules when it comes to photovoltaic­ systems“, Marko Schweitzer, Key Account Manager at Hanwha Q CELLS GmbH comments. “ADLER Solar’s decision as the most experienced full service provider of photovoltaic systems to install Q CELLS modules in their repowering projects is indicative of the high quality of our products.“

This is how the repowering process works

The process of repowering is designed to restore the original nominal power of photovoltaic systems with decreasing yield and as a result to maximise profits for the rest of the life cycle, thus ensuring the investor´s ROI. This method is worth considering for agricultural, commercial or industrial ground mounted and roof top installations alike. At first, the system must undergo an intensive appraisal. The project then is carried out on the basis of an individual strategy concept including a profitability analysis and possible financing options, and handed over together with the appropriate documentation after a test run. The professional execution as well as the use of quality components is a decisive factor for the success of the repowering measures.


”Being able to introduce Brazil to the infinite opportunities of a solar industry is a privilege for J.v.G. Thoma GmbH, and one that we are extremely grateful for. At the same time, this placed the ball squarely in our court, and the pressure to get the ball rolling quickly was high. Now that the lengthy initial formalities are out of the way, we can focus on making this project a success.“

The first DESERT solar module production in BRAZIL! Lets go ....
J.v.G. Thoma GmbH is delivering a DESERT turnkey production line to Brazil, the first of its kind and hopefully the first in many breakthroughs to leave the factory floor on their way to the largest country in South America. With a capacity of 30 MW, this is a small semi-automatic DESERT production line, but still a flagship in terms of DESERT solar module production and electricity generation in the country, now fully functional and ready to start with operation.

The machinery consists of DESERT production machines for high-efficiency DESERT solar modules built specifically for extreme hot climate, such as can be seen in deserts or in tropical areas. Made solely in Germany and built using the latest in DESERT and TROPIC module production, the systems inlcudes all cutting-edge technology.

Certified DESERT solar modules, DESERT containers, DESERT power plants and DESERT manufacturing machinery built using pioneering DESERT and TROPICS technology are now fully set up, and ready to perform. But powering on the machinery has been a long time coming. Up until recently, this advanced piece of equipment had been waiting for clearance at a port in Brazil. Now that the formalities have been dealt with, both J.v.G. Thoma and its customer in Brazil can get production under way.

J.v.G. Thoma GmbH is a company whose vision has always been to harness the infinite power of the sun and convert it into an inexhaustible supply of energy. But a vision such as this requires global reach, and this project has opened new doors. Brazil is not only a gateway to South American cooperation, but also the launchpad to international reach and expansion.

Following the delivery of this initial order, J.v.G. Thoma GmbH will be looking forward to an ongoing collaboration with the Brazilian company. From setup and initial training to setting the scene for a ramp up, J.v.G. Thoma will be there to provide expertise and assistance. Moreover, the company will be jointly responsible, along with the client, for the successful integration of the DESERT solar module factory.

In the future, bigger DESERT power plants will be set up on Brazilian soil, and together with existing turnkey production systems, they intend to take up a large share of the products and assets this sector will possess locally. J.v.G. Thoma plans to build up a local network of sales agents that can extend a premium offering to neighbouring countries in South America. Eventually, the company hopes to be able to expand its customer base to clients in North America.

Hans Thoma, general manager from the Thoma-group, is eager to acquire a substantial market share in Brazil, a growing country with tremendous potential for solar energy output. Having complied with local official procedures (Inmetro, TÜV, Fraunhofer CSP) and cleared the way for future business collaboration, he expresses his hope that the solar industry will henceforth expand quickly.

”Being able to introduce Brazil to the infinite opportunities of a solar industry is a privilege for J.v.G. Thoma GmbH, and one that we are extremely grateful for. At the same time, this placed the ball squarely in our court, and the pressure to get the ball rolling quickly was high. Now that the lengthy initial formalities are out of the way, we can focus on making this project a success.“
