Inspections

Metrological inspections

In order to prevent yield losses, metrological inspections can help to identify defects at an early stage.

Due diligence

Do you want to take over a solar plant or an entire portfolio? We check the technical aspects right through to the system documentation. We recognize defects for you and assess technical risks.

Construction progress control

We provide consulting during the construction phase and check the construction progress. In this way, defects and contractual deviations can be detected at an early stage and countermeasures can be taken.

Acceptance and commissioning inspection

Extensive testing is essential so that no defects are overlooked during the acceptance/commissioning phase.

Warranty end check

Until the end of the warranty, hidden defects may be displayed and repairs or replacements can be demanded. We help you to make hidden defects visible and advise you on the next steps.

Technical asset management (TAM)

In order to obtain an unadulterated status report for your plant(s), it makes sense to have it checked from time to time by an independent party.

Assessments

We create reports for:

Yield reports and simulations

We create yield assessments and simulations for planned and existing PV systems. For simulations, we use established software such as PVsyst. Our reports comply with the state of the art and are accepted by banks. A yield assessment includes the following points:

Evaluation of location-specific irradiation values
Simulation of the system yield
Determination of the performance ratio (PR)
Detailed loss analysis
Evaluation of the results

Damage report

Damage reports are required for insurance and legal disputes. A damage report includes the following points:

Identification, analysis and categorization of the damage
Determination of the cause of the damage
Quantifying the repair costs
Evaluation of damage-related yield losses or reductions

Defect assessments

Defect assessments are equired for warranty and complaint applications as well as for the takeover or assignment of a PV system. A deficiency assessment includes the following points:

Identification, analysis and categorization of the defects
Analysis of the effects and risks
Quantifying the repair costs
Determination of possible warranty claims
Recommendations for action

Glare assessments

Glare assessments evaluate the glare effects of planned or already erected photovoltaic plants as well as the resulting risks for road users (also for air traffic in the case of near aerodromes). In addition, glare assessments can be used to determine the immission loads caused by reflections on zones requiring protection, such as residential areas.

Simulation-based determination of glare effects
Risk determination for traffic (road and air traffic)
Quantitative and qualitative analysis of immissions
Recommendations for countermeasures

Evaluation of existing reports

We check existing reports for completeness and correctness of the content and summarize the results in a separate report.

Engineering and Consulting

Support with all technical project planning steps or complete takeover of the planning.

In particular, grid connection planning, support during planning/implementation
in accordance with the specifications of the grid operator.
