Yield Assessment
A PV yield analysis is an elementary component of PV plant planning.
The starting point and elementary component of PV plant planning.
The most reliable basis on which to plan your project
greentech will prepare a substantiated yield assessment, taking all relevant factors into account, resulting in a detailed and realistic forecast for your PV farm, so you can be sure of the exact potential of your actual or planned photovoltaic installation.
In estimating the most realistic maximum yields and performances of PV systems, we have the particular benefit of our many years of experience in operational management. We can reliably assess and justify why forecasts may have been too optimistic or too conservative.
When does a Yield Assessment make sense?
A PV yield assessment enables a precise prognosis of the profitability of a future PV project and serves to provide investors or banks with justification in terms of the profitability of your project.
The yield assessment serves as an argument during purchase or sales negotiations. It provides objective, specialist justification of the proposed purchase or selling price. It is not uncommon for the various parties to commission their own yield assessments, and the results and estimates thereof are subsequently discussed and debated during the course of the negotiations.
A yield assessment offers potential investors transparency regarding the projected income of the photovoltaic plant. This makes it possible for them to calculate directly, whether or not it will pay them to participate in the project in question.
If there are to be any technical changes to the plant, the yield evaluation provides information as to whether the conversion will result in significant improvement or even deterioration in terms of yield. For example, replacing old inverters with new models could result in significantly increased yields, due to the higher efficiency levels of the new components.
Different focuses in terms of design also result in differences in yield potential for the plant. Do you already have a design? We would be happy to check whether the yield could be optimized even further by making specific changes to the plant design. If you have several proposed designs, we will gladly identify the proposal with the highest yield prospects or advise you on what else you should take into account when making your decision.
As owner’s engineer, we provide you with substantiated analyses and evaluations of external yield surveys.
This gives you, as the project planner or operator, an independent view of the potential earning power of your PV plant.

Benefits
Reliable yield forecasts through practical experience and the latest yield simulations
Our analyses and evaluations are based on our technical expertise and our comprehensive experience in the field of operation and maintenance (O&M). After a holistic consideration of all the parameters and sources that are significant for a yield assessment, we will provide you with the information you need. We do not sugarcoat anything – instead, we provide a realistic, objective assessment of the expected yields, that can be used by all parties involved.
Over 100 successful bankable yield assessments
As owner’s engineer, besides preparing our own yield reports, we also regularly analyse and evaluate externally prepared documents. We are happy to present the results to you and explain our assumptions and conclusions, giving you a second opinion and the opportunity to compare them with the initial report. We have prepared or reviewed more than 100 yield reports over the last few years.
White listed by banks, potential buyers and technical consultants
With our extensive experience as photovoltaic specialists, we are well established in the market. We are one of the largest independent operators of solar power plants worldwide, with a steadily growing portfolio. The quality and reliability of our yield assessments are highly regarded by financial institutions, investors, technical consultants and customers alike.
A comprehensive consulting approach & ongoing support
We will gladly continue to support you after the planning and start-up phase: we support you during the construction phase, and thereafter, we ensure the best possible performance from your plant throughout its entire life cycle. This means that you have a long-term partner standing by, who not only knows your plant, but also understands it.

FAQ
greentech offers detailed yield assessments that take all relevant aspects into consideration and offer objective results. Our solar yield assessments are accepted by all banks and technical consultants, which makes them “bankable”. Furthermore, greentech is “whitelisted” at many financing banks as a professional provider of yield assessments. These whitelists are made available to project developers and investors, as a recommendation of bankable service providers. To secure the financing of a project, it is critical that the yield assessment is accepted by the financing party.
Yes we can. Part of our role as owner’s-engineer is to analyze and evaluate existing yield assessments, which we do regularly. This gives you an independent view of the potential production of the PV plant and a good basis for negotiations. This is also common for larger projects, as the financing bank will require more than one independent photovoltaic yield assessment, in order to increase the reliability of the results of the prognosis.
As soon as we have received the relevant project documentation, such as .pan files, topography, layout and component datasheets, we will need 1-2 weeks to work through the project and finalize the report.
The production simulation alone starts at EUR 950 for one iteration, while the full yield assessment starts at EUR 1,990. Both prices are dependant on the complexity and size of the project.
A simulation is the file (PDF) exported from the simulation software we use, PVsyst, which includes all the results from the actual simulation. A full yield assessment takes these results into account, but goes further by explaining the results in detail, including an analysis of the choice of components, the layout of the project and the DC/AC ratio. All these additional parameters are carefully checked and examined with regard to optimisation potential. The results of this analysis are collected and presented in a comprehensive report.
