# RELEASE 08.15.0

April 29, 2021

* **Model LeTID on your Multi-Year Predictions**
  * Light and elevated Temperature Induced Degradation (LeTID) is an important degradation mechanism that appears in certain solar modules.
  * As more research emerges, solar modeling software needs to be able to simulate LeTID degradation to ensure that all risks are known and understood.
  * Within the Prediction Simulation Settings, PlantPredict users now have the ability to turn on LeTID when running a multi-year prediction and then define the LeTID rates on an annual basis.
  * [<u>More information can be found in our Models and Algorithms section of our website</u>](https://plantpredict.com/algorithm/dc-array-behavior/degradation-and-plant-construction-schedule/light-and-elevated-temperature-induced-degradation-letid/)

BUG FIXES

* Plant Predict: Arrays, Inverters and DC fields with numbers >1 inaccessible.
* Fix block navigation issue.
* Plant Predict: Default values for backside mismatch and structure shading for bifacial modules are missing.
* Saving a map prediction with a bifacial module should apply the module backside mismatch to the corresponding DCField.
* Error Message does not disappear after saving with correct info.
