Solar Energy Yield Studies

What are solar energy yield studies?

Yield studies assess the potential of your solar power plant by studying possible installations for optimal performance and calculating its performance ratio. A solar energy yield assessment covers parameters such as performance ratio, energy yield value (annual summary as well as details for specific months) and expected energy losses of the system. An independent site visit can evaluate the overall suitability of the location and the chosen technology.

Solar power plant yield studies are essential for evaluating the financial viability of a solar project, helping project developers and investors to assess the expected energy output, operating costs, and potential revenue. These studies can also help optimise the design of the solar energy system to maximise energy production and efficiency.

Why are yield studies important?

Solar power plant yield studies give stakeholders an overall view of the project’s energy output and future cash flow. Solar yield analysis is one of the crucial documents for all owners/operators, EPCs and financers involved in the project.

WHAT DO I NEED TO PREPARE FOR A SOLAR ENERGY YIELD STUDY?

To prepare for a solar energy yield or solar power plant yield study, and to ensure that the study data is reliable, you need to provide basic technical parameters (type/model of applied modules and invertors, inclination, type of mounting structures and GPS co-ordinates.  

TÜV SÜD provides a reliable, transparent and unbiased view of your project’s risks and potential

TÜV SÜD’s experts have longstanding international hands-on experience in yield studies services and implications thereof. We provide you with a fully independent overview of the solar power plant during the design, construction and operation stages of a project.

OUR SOLAR ENERGY YIELD ASSESSMENT STUDIES INCLUDE:

• SITE ASSESSMENT

TÜV SÜD experts perform a site visit to assess potential obstacles (trees, mountains, buildings) that can negatively impact plant operation and its future solar power net energy yield.

• METEOROLOGICAL DATA

We confirm the completeness and adequacy of meteorological and climatic data used as inputs to the solar energy yield calculation. We use the most accurate meteorological data sources from ground stations or satellites and compare them with other independent sources available for the location (e.g., Meteonorm, NASA, SolarGIS).

• ENERGY LOSSES

Our experts provide a summary and a detailed quantification of the volume and types of system losses.

WHY CHOOSE TÜV SÜD?

With more than 500 solar power plants completed globally, TÜV SÜD‘s established solar power hubs and skilled teams worldwide help manage your projects independently and impartially.
