## Solesca v2 (October 17, 2026) (latest)

### Design on the ground as it is

Solesca v2 is live for every Solesca user. After more than two years of development, this release brings terrain tracking and a new 3D view to early-stage solar design. Terrain tracking is available as an add-on.

**Feature**

### Terrain tracking and 3D

- **Terrain tracking.** Lay out ground-mount arrays on the site's slope. Rows follow the ground, and layouts account for your racking limits. See [Terrain tracking](https://docs.solesca.com/editor/terrain/).
- **Full 3D.** Inspect rooftops, carports, and ground mounts from any angle. Change the sun's position through the day to review shadows. See [Map and views](https://docs.solesca.com/editor/map/).
- **Pile reveals.** View piles in 3D and color them by reveal height to find the tall ones. See [Pile reveals](https://docs.solesca.com/editor/terrain/#pile-reveals).

### Modeling and electrical design

- **Solesca Core and Solesca Pro.** Two new simulation models built by Solesca. Core is the default, Pro supports terrain and engineering designs, and NREL SAM remains available. See [Model energy](https://docs.solesca.com/editor/simulate/).
- **New shading model.** Updated shading assessment for your layouts.
- **Inverter groups.** Wiring zones are replaced by groups that account for inverter MPPT inputs and datasheet DC/AC limits. See [Inverter groups](https://docs.solesca.com/editor/inverter-groups/).
- **Energy modeling templates.** Reuse modeling assumptions across designs.
- **Module bifaciality.** Set bifaciality on the module instead of each field.

### Layout tools and deliverables

- Racking products are available as a library of [terrain products](https://docs.solesca.com/system/racking-products/).
- [Racking packages](https://docs.solesca.com/downloads/racking/), [PVsyst files](https://docs.solesca.com/downloads/pvsyst-and-solarfarmer/), and [3D DXF](https://docs.solesca.com/downloads/rendering-cad-google-earth/#cad) exports.
- An alignment point with a 3×3 alignment grid.
- Circle and rectangle obstruction tools.
- Fire walkways at the distance you specify.
- Choose when [template updates](https://docs.solesca.com/system/design-templates/#keep-a-field-in-sync) apply to a design.

### Projects, teams, and accounts

- Project status, priority, and lead person.
- Design locks to preserve a version of your work.
- Two-factor login, with organization-wide enforcement.
- `Ctrl+K` on Windows or `⌘K` on Mac to search projects, portfolios, designs, and people.
- Multiple named API keys, each revocable on its own.
