Reliable assessments of your PV power plant investments
Engineering, procurement and construction (EPC) contractors, owners/operators and financers of photovoltaic (PV) power plants need a reliable overview of the energy yield of their projects. During the planning stage, stakeholders of new PV power plants require an assessment of the potential yield in a given location.
Sellers and buyers of existing PV power plants need to consider the real performance data and expected energy yield of the plant. When a power plant project does not perform according to project design, stakeholders need an independent recalculation to determine the real level of energy losses compared with the initial expectation.
TÜV SÜD provides you with a fully independent overview of the PV power plant during the design, construction and operation stages of a project.
TÜV SÜD experts perform a site visit to assess potential obstacles (trees, mountains, buildings) that can negatively impact plant operation and its future yield.
TÜV SÜD confirms the completeness and adequacy of meteorological and climatic data that are used as inputs to the yield study calculation.
We use the most accurate meteorological data sources, whether from ground stations or satellite, and compare with other independent sources available for the location (e.g. METEONORM, NASA, PVGIS classic and PVGIS-SAF)
Our experts provide not just a summary but also a detailed quantification of the volume and types of system losses, such as ohmic losses, module quality and mismatch losses, cable losses, reflection losses, losses resulting from temperature effects and dirt on the module surface, etc.
We also take into account the uncertainty arising form variable factors and base our reports on P50 and P90 probabilities.
