Valentin PVSOL Expert v5.5.R5

A real-world representation of the shading from surrounding objects is extremely important for precisely calculating yields. You’re therefore looking for a program which takes shading into account as analytically as possible? PV*SOL® Expert does just that! You can visualize all roof-integrated or mounted systems – even in the ground – with up to 2,000 modules in 3D and calculate shading on the basis of 3D objects.

The user-friendly 3D menu navigation is divided into the five sections of terrain view, building view, module coverage, module mounting and module configuration. Simply select possible shading objects and position them on the terrain or the building. PV*SOL® Expert then calculates how often on average the modules are shadowed by the objects and displays the result in graphical form.

Your benefit: the visualization in 3D mode provides you with detailed information on shadows cast at various times of the day and year and consequently on likely reductions in yield.

Modeling of PV Area and Vicinity – The Terrain View

PV*SOL® Expert leads you in a few easy steps to your target. First, you select one or more PV array buildings from a collection of common building types and sizes as required. Dormers, bay windows, walls, saw tooth roofs, and projecting roofs can also be covered with PV modules. It is possible to model the available roof area with millimeter precision by entering measurements for the roof overhang and restricted areas. You then simply enter the objects that could cause shade – buildings, trees walls, masts, etc. – and size them. Objects in the distance can be taken account of as a horizon line.
Restricted Areas and Shading Objects on the Roof – The Building View

When the dimensioning of the PV array building is complete, in the next step you can position and scale restricted areas and other shading objects on the roof, such as windows, chimneys, dormers, fire walls, satellite dishes, etc.
Module Coverage

The coverage of roof area with the maximum possible number of modules is carried out automatically or manually by selecting the coverable areas. Where required, PV*SOL® Expert can promptly display the annual reduction in irradiation (direct and diffuse radiation) for every point on the PV area and every module. In this way, you can make a more informed decision as to whether a module is viable or not at this position.
Optimizing Module Configuration

The modules selected by the user are then configured together with the inverters. The program automatically configures the individual strings, but the user is able to optimize the allocation depending on the shading situation.
Configuration Tree

PV*SOL® Expert offers an excellent side menu with a tree structure showing inverter configuration and associated functions. By clicking on an element in the structure, the selected part of the system configuration is highlighted and the camera zooms in on it. The side menu can be hidden as required.
Shade Animation

A wide range of animation tools are available to the user when working with the software, so that each shade scenario can be visualized at any point in time.
Yield Simulation

A yield simulation is now run in PV*SOL® Expert’s technical dialog, taking into account the influence of bypass diodes and the partial hourly shading of each module.
