PKV Energie GmbH & Co. KG has assigned ADLER Solar to facilitate a Repowering project. In a first step, our PV experts check and analyse the performance of a roof-mounted PV system for the Frisia-based company, then locate and document the cause of error as well as the technical defect. Next – in coordination with the distribution system operator – all PV modules will be dismantled and new ones installed. Part of the assignment is a STC performance measurement of these 8,300 installed PV modules. The Repowering project is currently well underway and expected to be concluded by July. The PV plant is located on the roof of the affiliate company Papier- und Kartonfabrik Varel GmbH & Co. KG.

The ADLER Solar Repowering Programme aims to optimise all crucial technical as well as commercial aspects of a PV system so that the performance drop is almost entirely being compensated. The added value for customers is a significant increase in yield, protection of investment and quick ROI.

Has your PV plant dropped in performance?

It happens again and again that PV modules have a significantly lower efficiency rate than promised or that incorrectly installed respectively damaged components cause a creeping minder performance. Plus, many modules show problems because manufacturers have not tested long-term performance thoroughly and introduced them prematurely to the market. In this case it makes sense to exchange solar modules ahead of time.

Your advantage: as an operator, you continue to receive the earlier agreed upon feed-in tariff.

We will be happy to conduct a performance analysis for you and consult you on how to bring the performance up to speed again.

Now available as a factsheet: the ADLER Solar „RES-Project Japan“

The end of 2015, ADLER Solar received the award to build a PV system as part of a PV training centre in Japan by Deutschen Energie-Agentur (dena), embedded in the dena-renewable-Energy-Solution-Programme (RES).

In May last year, the training centre in Yokohama was inaugurated with a festive opening ceremony accompanied by high-ranking representatives from the Japanese world of politics and business. The objective of the training centre is to pass the long-standing experience and expertise „Made in Germany” on to the Japanese market.

A summary of all data and facts concerning this project is available in a factsheet (in German) by dena and offered as a free download on their website.

We look forward to hearing from you!

Our Sales Director, Claas Oltmann, and his team are waiting to answer your inquiries.
