Photovoltaic System

PV systems need long-term funding and have a service life of several decades; therefore it is necessary to make sure that the photovoltaic system generates the desired income. Often, however, PV systems owners are not aware of decreased profits. An expert for photovoltaic systems can verify that a photovoltaic system was installed without fault on the roof and whether the PV modules will last as long as the warranty. A photovoltaic system consists of these main components PV modules, inverters, mounting system and electrical installation. With proper planning, proper installation and ongoing control, the lifetime of a photovoltaic system is three to four decades.

TÜV certified appraiser for photovoltaic

Photovoltaic appraisals from a graduated engineer & TÜV – expert

As a recognized expert in photovoltaic systems with certified qualifications from TÜV Rheinland I create reports for photovoltaic systems. I evaluate completed systems, accompany and support projects that are still in planning, this can be for photovoltaic systems of all kinds.


TÜV

Why is this an important seal of approval?

The TÜV is well known in Germany and also worldwide. TÜV, is for many people synonymous with an impartial tested quality seal of the highest standards and certitude, and rightly so. The TÜV Rheinland Group thus reviews and documents as an international service company, the quality of expert knowledge.

Official Expert

An expert checks with special measuring instruments and Know-How, the compliance with DIN standards, VDE regulations, structural or corrosion of metals. An appraiser will check the PV system before the inspection, before the warranty period ends or if needed when suspicion of decreased output arises.

  • Subject matter and content of a PV-Report

  • As part of an expert report all relevant details of a photovoltaic system are recorded and evaluated. Usually, the overall structure of the photovoltaic system is also tested, as to the condition of all the components, the wiring and the electrical installation. The specified documentation of the system is also examined and compared with the actual condition of the system. All components are also separate selectable.

     

  • Site Analysis and Revenue Forecasting

    • Photovoltaic systems for generating electricity are not only a contribution to the energy revolution. For the most system operators, both private and commercial, they are also a medium-to long-term investment, using public subsidies thus being co-financed investment. To have a predictable Revenue Forecasting is mandatory.

    • Profitable PV systems require careful planning using highly efficient and durable components and also the optimal workmanship. We support you in the dimensioning of your photovoltaic projects. A detailed profitability and earnings forecast is the ideal foundation for long-term financing.

     

  • Profitability calculation in advance

  • Profitable PV systems require careful planning using highly efficient and durable components and also the optimal workmanship. We support our partners and customers in the dimensioning of their photovoltaic projects. A detailed profitability and earnings forecast is the ideal foundation for long-term financing.

     

  • Yield assessments, performance assessment and analysis of defects

  • Will the earnings stay constant like they meant to be or will the "Electricity Harvest" of your PV-system remain well below desired or predicted values? This can result for various reasons.

     

  • Function and installation testing

  • As a TÜV-certified appraiser, we check all components of your system, detect and describe damage as well as installation and / or material we also check that your PV system has been competently planned and designed properly, adequately sized and has been professionally installed.

  • Defective workmanship, supporting structure and cabling

     

    • Your modules can be measured by us. Quick and easy performance testing of installed solar modules by using the Trika - device http://www.tri-ka.com/de/

 

  • Objective performance assessment

  • Objective economic calculations and independent fault analysis can not only be helpful in resolving performance deficits quickly, cheaply and effectively. They often clarify who is responsible for necessary repairs or renovation works and their costs, the client, designers, craftsmen or the component manufacturers, as the case may be.

     

  • Expertise and objectivity

  • Photovoltaic systems for generating electricity are not only a contribution to the energy revolution. For the most system operators, both private and commercial, they are also a medium-to long-term investment, using public subsidies thus being co-financed investment.

     

  • Other services offered

  • Before activation of your system:

    • You have purchased a photovoltaic system and want an independent person to control all aspects of the plant before the final inspection and handover? Ask us to be there by the final inspection as an independent party!
    • Have all the components been delivered, exactly as you bought it? We can test the modules on the existing site, and can then see if the modules installed on the roof, are exactly what you paid for.
    Poor product quality, micro-cracks, should be claimed

After the system has been handed over to you:

  • Your system is already in operation and you notice errors - what now? We can help you! Your modules can be measured by us. Quick and easy performance testing of installed solar modules by using a characteristic curve measurement device.
Verify whether the power of the delivered module
corresponds to the values in the data sheet

I will gladly stand by you and use my expertise as an engineer and Authorised Expert for Photovoltaic Equipment (TÜV) to help in every way possible.

You can depend on us! We would be pleased if you contact us and we can help you!
