PV*SOL is a global simulation program for photovoltaic systems, which puts the planning and design of PV systems on a secure basis and reliably calculates system profitability. The sector solutions for PV systems, PV*SOL and PV*SOL premium from Berlin-based Valentin Software, have been adapted to the latest technical developments for 2020 and expanded to include the latest applications.
With the new, revised versions, system designers and operators can design their PV systems according to the latest knowledge, simulate precise yield calculations under location-specific conditions and thus also carry out precise profitability calculations taking government subsidy measures into account. This applies both to the adoption or input of geometric data to represent a 3D model as the basis for positioning the modules, as well as the inclusion of complex parameters for detailed technical replication of the entire PV system.
The necessary databases such as climate data, PV modules or inverters are included and regularly updated. In the PV*SOL 2020 versions, access to the databases is supplemented by the very useful function of online access. On the one hand, the online databases contain the system data records, on the other hand, the data records created by users themselves are stored there. The automatically created user ID can be shared with other people, so that multiple users can access self-created data records. Self-created data records already produced in earlier versions can also be integrated into the new online database.
The function of recording electrical consumption or the consumption profile, which is so important for the profitability calculation, has also been fundamentally revised and expanded. Measured and imported load profiles, appliances with a load profile and individual appliances are now combined in one dialog. Due to the fundamental revision of the user interface and the adjustment of the functionalities, the relevant appliances can now be defined more easily and new appliances can be created more quickly. This also applies to the detailed entry of electric vehicles, which can be divided into several groups.
When inputting the installation of the module array, 3D models can be imported via an interface, for example using photos of drone flights. This enables floor plans, cadastral maps and screenshots from web-based satellite maps (e.g. Google Earth) to be directly imported into the 3D visualization and integrated into a project to scale. When configuring the modules with the automatically determined inverters, it is now possible to define more than one inverter group even on jointly configured module areas. This can be used for example at the first inverter to connect 20 modules of module area A and 10 modules of module area B, while at a second inverter only 14 modules of module area A and 12 modules of module area B are connected. (See screenshot.)
The detailed circuit diagram provides considerable support for construction work. Particularly in the case of complex systems, attention has been paid to a clear representation of the configuration of individual modules and strings right through to the inverter and the feed-in point.
