Optimise your solar power conversion efficiency
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.
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.
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’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.
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.
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).
Our experts provide a summary and a detailed quantification of the volume and types of system losses.
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.
An energy yield assessment is a process of estimating the amount of energy that a renewable energy project, such as a solar power plant, is expected to generate over a specified period, usually a year. It involves analysing various factors such as solar irradiance, temperature, wind speed, equipment specifications, and site conditions to calculate the project's expected energy output.
The assessment is typically done using software tools and validated through on-site measurements or inspections. The energy yield assessment helps project owners, investors, and lenders understand the project's expected performance, identify potential risks, and optimise the plant's design and operation to maximise its energy output and financial returns.
The energy yield of solar energy refers to the amount of electrical energy that can be generated from a given amount of solar radiation that falls on a solar panel over a specific time, typically a year. It is measured in kilowatt-hours (kWh) per kilowatt-peak (kWp) installed solar capacity.
Several factors, such as the efficiency and orientation of the solar panels, shading, temperature, and weather conditions, influence solar energy yield. The energy yield can be estimated through energy yield assessments that take into account these factors and use solar irradiance data and simulation tools to calculate the expected energy output of a solar power plant. The energy yield of solar energy is an important consideration for investors, developers, and operators of solar power plants as it affects the project's financial returns and overall viability.
At a time when our thirst for energy is greater than ever, managing our future energy needs is an increasingly delicate task.
