**SunSolve Bifacial Parameters** — In collaboration with [PV Lighthouse](https://www.pvlighthouse.com.au/) and **[SunSolve](https://www.sunsolve.com/)**, PlantPredict can import SunSolve-derived bifacial inputs to improve agreement between detailed ray-tracing and PlantPredict’s bifacial rear-irradiance model. On the DC Field **Losses** tab, enable **SunSolve Bifacial Parameters Import** to supply **SunSolve Structure Shading**, **SunSolve Combined Front + Back Mismatch**, and **SunSolve Transmission Gain**, and read how these terms feed the model on the [Rear (bifacial) plane-of-array irradiance](/models/poa-irradiance/rear_irradiance) documentation.

### **Wind Stow: Stow Dwell Time**

**Stow Dwell Time** is now available for the PlantPredict **Wind Stow** model (DC Field **Table** tab). It sets how long wind gust must stay at or below the **Wind Gust Threshold** before normal tracking resumes after a stow event, reducing unrealistic rapid cycling. See [Wind Stow](/models/tracking/wind_stow) for behavior and defaults.

### **3D Shade Scene: Map Builder and PVC Download**

**Create shade scene from Map Builder** — You can create a 3D shade scene directly from the Map Builder header, without exporting a PVC from Map Builder and uploading it to the prediction. After a scene exists, you can also push updates from Map Builder, avoiding a manual download-and-upload loop.

**Download edited 3D scenes** — On **3D Scene Overview**, **Download Data** exports the current PVC, including custom 3D objects that were added or edited in the 3D shade scene.

## **Improvements and Bug Fixes**

* **License checkout (Stripe)** — New self-checkout flow to purchase licenses, including add-on extensions.
* **Free tier trial** — New self-service path for Free tier users to start a full-featured trial.
* **Irradiance optimization (V13 beta)** — Movement penalty in the built-in irradiance optimization now matches the documented use of **Rotation Speed**; see [Irradiance Optimization](/models/tracking/irradiance_optimization). (V13 beta prediction logic.)
* **Multi-year predictions and 3D losses (V13 beta)** — Out-years (year 2 and later) in multi-year predictions now apply 3D shade-scene losses consistently with year 1. (V13 beta prediction logic.)
* **Report downloads** — Access to report downloads (except Plant Summary) is limited to paid subscriptions.
* **3D object move** — Improved behavior when moving objects in the 3D shade scene.
