ADLER Solar has been providing services within the German and European photovoltaics industry since April 2008. Over 4.5 million modules have been processed over the past 8.5 years and more than 1.800 system assessment reports have been produced. During this time, around 100 PV experts working at the company headquarters in Bremen have been continuously enhancing their breadth of experience and their technical knowledge, enabling them to make positive strides within the industry:
over this period, ADLER Solar has implemented each of the seven large recall campaigns for each respective module manufacturer and on each occasion it has taken ownership of the complete project execution process: from project management and customer communication to on-site troubleshooting across Europe through to logistics services, product preparation and test and repair services in the ADLER Solar Service Centre. Thanks to our extensive experience and specialisation, we are able to carry out these services in a particularly effective and efficient manner.

Since its inception, ADLER Solar has been developing customised solutions and services for its customers with constant attention to keeping current requirements and the benefits for the target group in mind:

In March 2013, ADLER Solar was indeed one of the first service providers to implement the electroluminescence method of quality assurance also for PV modules which had already been installed. This has now become an established measure within the industry to save customers costs and time. We have always counted our own technical developments and process optimisation measures amongst our core competencies. Amongst other things, these also include what is referred to as the crack-age-test, an inspection method which has been developed by ADLER Solar to distinguish between older micro-cracks in crystalline PV modules and those which have just appeared – this offers added value for insurers in particular when assessing claims.

Our selected strategic partnerships are just one of the ways in which we fulfil our claim that we offer a one-stop-shop for our customers. For example, as a result of the cooperation with pvXchange, one of the largest trading platforms for PV modules and components in the world, ADLER Solar is able to offer its customers replacement modules and inverters for existing systems at any time and with minimal notice.

With this combination of specialist knowledge and experience, an orientation towards solutions and technical development work, selected cooperations and a motivated team, ADLER Solar has succeeded in adapting to the changed customer requirements even once the boom years of the German PV market from 2009 to 2012 were over, offering an optimised portfolio.

Currently, as demonstrated by this year’s Intersolar Europe held in Munich, the industry is being driven by three particular factors: repowering, claims management and inverters. The trend, which is currently referred to using the buzzword “Repowering” is being strongly fostered at ADLER Solar: for years, ADLER Solar has been further developing the core competencies relevant to repowering, meaning that it is now the first port of call for banks, insurers and system operators whenever it is a question of the full exploitation of the potential of PV plants.

Where claims management is concerned, ADLER Solar has been working in partnership with Germany’s leading insurers for many years. These insurers are convinced of our tried and tested process from claim notification through to repair, which significantly reduces both repair times and costs. A firm diary date for insurers is now the ADLER Solar Insurance Day, which takes place twice a year. Here, PV and insurance experts come together for discussion and speakers provide insights into current topics relevant to insurance – it’s the ideal platform to exchange ideas and to make contacts.

For six months now, ADLER Solar has also been offering its customers inverter services. Figures demonstrate that a defective inverter can lead to significant losses in income (see below). Our inverter team possesses many years of experience in this area as well as impressive levels of expertise and turnaround times.
“For more than eight years, we have been supporting our customers with the experience and expertise that we have accumulated. As a result of our individual solutions and diverse service offering as a one-stop-shop, we are able to meet high expectations where quality is concerned and therefore offer our customers real added value”, said Gerhard Cunze, Executive Partner at ADLER Solar.

 

Inverter repair and performance optimisation: Make the most of the quieter winter months

In the specially equipped ADLER Solar Service Centre, inverters are tested for their efficiency and repaired – this takes place during the winter months in which only 10% of the yield is generated

Inverters are a key element of every PV system and are no longer simple current transducers and voltage transformers. They are actually rather complex data or energy interfaces in the context of the Smart Home with monitoring, control and storage functions. Faultlessly running inverters form the basis for a high solar yield and reliable supply safety. Inverters are exposed to climatic conditions and potential component damage caused by fire, surge voltage or rodents all year round. What’s more, device electronics are designed for an average service life of 6 – 10 years, after which parts of the power electronics may fail and the solar energy can no longer be fed.

Make the most of the low-yield winter season to have your defective inverters expertly repaired, ensuring that your devices run perfectly again in the coming spring and summer and that your solar yield is in safe hands. The complete offer from a single source at the ADLER Solar Service Centre comprises:

  • Functional testing
  • Fault diagnosis / cause analysis
  • Repairs
  • Refurbishing (replacement of performance-related components) / general overhaul
  • Transport service and provision of packaging materials

 
„In the winter months from November to February, only approx. 10% of the total annual yield is generated due to low solar radiation. Take advantage of this period to repair or refurbish your inverters, in order to avoid a significant loss of revenue in the summer months. As a sample calculation for a summer month in northern Germany: for a 15 kW device installed in 2009, in a defective inverter this means a daily yield deficiency of 15 kW * 43.01 cent * 8 = € 51.61″, explains Gerhard Cunze, Executive Partner of ADLER Solar.
