For portfolio managers

You don’t yet have your own WIRSOL system but manage wind and solar systems? You have renewable energy systems in your portfolio? Then benefit from the know-how we have gained from over 8 500 installed photovoltaic and wind systems. We offer a broad range of services for portfolio managers in particular:

  • Comprehensive advice

    We do everything we can to optimize your systems. Our offering thus includes the examination of additional commercial potential. We can advise you direct marketing; system services for network operators; flexibility marketing; integration into own-consumption models; close proximity consumption concepts and on the combining of your systems with storage solutions.

  • Technical and commercial operational management

    We can offer you comprehensive experience gained in the management of over 550 megawatts of installed capacity. Our range of services thus also includes the winding up of operational business activities – from the management of mail and receipts through on-going accounting to the monitoring of compliance with all on-going contracts and archiving obligations. We can handle all your correspondence with energy suppliers, contractual authorities and the authorities as well as ensuring compliance with all the requirements made by licencing law and the authorities and verifying timely compliance with all contractual obligations.

  • Repowering

    We are your strong partner, particularly following the expiry of feed-in tariffs. Our experts can identify solar systems with high optimization potential; examine all technical and operational aspects and calculate the potential for repowering. Our strategy is to only select systems which can deliver solid returns, independent of how financial markets develop.

  • Solution of legal issues

    We can provide you with support concerning legal issues. Our experts can examine all relevant documents for you; select the corresponding expert assessors and develop corresponding recommendations for an optimum outcome.

  • Technical controlling

    We focus on a comprehensive system concept and regular reporting, enabling us to ensure that your solar and wind power systems deliver optimum performance. In addition to the implementation of technical specifications for legally compliant operations, we can also take care of the technically practical configuration of your systems. Our goal? The long-term, disruption-free, high-yield operation of your systems.
