Energy yield assessment
Energy yield assessments are used to determine the energy potentially produced by a planned PV power station and have a direct impact on its projected bottom.
In today’s world, calculating the expected average energy yield (P50) is insufficient, so we instead calculate P90 probability values (or P75 / P80 if required) so that organizations bankrolling solar projects can accurately determine the level of risk.
Our expertise ensures the highest level of accuracy at every stage in the calculation process:
Solar resources: Our Engineers have more than 15 years working on this particular topic, and we select our weather data sources according to their relevance for each location. Choosing the right weather data is especially important when calculating P90 probability values.
Production calculation: TDSI engineers are experts in photovoltaic modeling, including parameter settings and laws of variability. We avoid assumptions in Loss parameters such as LID, Soiling, IAM, mismatch loss, Quality loss and incorporate theoretical results while analysis. Such expertise is essential when calculating a realistic P90 probability value.
