The dynamic simulation program with 3D visualisation and detailed shade analysis for PV systems.
With the new PV*SOL Expert, you can position and size 3D objects to accurately determine the effects of shading from nearby objects on photovoltaic performance. |

PV*SOL Expert is a high-end design tool which provides the most exact level of analysis when optimising and configuring PV module coverage. It is squarely aimed at those who want the best.
With both PV*SOL Pro and Expert you can:
- Choose between Gridcon (for grid-connected systems) and the Set (for both grid-connected and off-grid systems)
- Calculate multi-string inverters with the corresponding number of MPP trackers and various series/string configurations.
- Design grid-connected PV systems quickly and easily while the program checks all physical criteria and threshold values (e.g. output, voltage and current)
- Determine the number of modules for each sub-array with the roof layout facility
- Produce professional client reports with precise graphics and data.
What can PV*SOL Expert do that PV*SOL Pro can't?
- Calculate shade frequency distribution for each individual module.
- Optimise PV module coverage using this information.
- Define the extent to which roof objects could cause shading.
- Precisely customise surrounding objects with far greater speed and accuracy.
- Produce a 3D animation of shading over a day or a year.
- Create images for customers of what their property and its surrounds will look like with integrated modules.
- Take screenshots of the visualised environment to import into your reports.
Shading is simulated in 10 minute intervals. With the new Photoplan option you can create a photorealistic plan of your roof areas. With just a photo of the roof and a few reference dimensions you can create a representation of the property with integrated modules.

Automatic and manual roof coverage options visualise annual irradiation reduction for any part of the PV area and for each individual PV module. This helps the user to decide which modules to remove or relocate.
The modules are configured with the inverters and individual strings are calculated automatically. The user is then able to optimise allocation depending on shading.
The 3D ground and roof objects are fully customisable, taking into account restricted areas, and objects in the distance can also be modelled as a horizon line. Several buildings or dormers can now be covered with PV modules. Coverable objects include buildings, walls, bay and dormer windows, sheds and projecting roofs. These objects can all be covered with PV modules and shading objects.
