Performance ratio (PR) assessment effectively assesses the health of a PV power plant with the most cost effective solution.
As an owner, investor, lender and developer looking into solar projects you can rely on Performance ratio (PR) assessment to verify the overall quality of new and already operational PV power plants.
Performance ratio assessment measures the partial (PV modules, inverters, strings, arrays) or complete PV power plant efficiency.
By means of a self-powered system which is easily installed on site, data is collected, stored and sent for post-processing.
Thereupon, experts analyze the data determining not only differences between the actual and contractually specified energy generation but also the impact of any deviation from the project specifications which might result in low performance.
Performance Ratio Assessment provides stakeholders the security of getting accurate and independent information for an evaluation of the return on investment.
TÜV Rheinland PR Assessment is an independent assessment which provides first-hand PV power plant performance information to project stakeholders and brings confidence to decision makers about the investment.
