The design and simulation software for photovoltaic systems

PV*SOL premium is a dynamic simulation program with 3D visualization and detailed shading analysis for the calculation of photovoltaic systems in combination with appliances, battery systems and electric vehicles.

PV*SOL® premium


With PV*SOL premium, the industry standard for photovoltaic design programs, you can design and simulate all types of modern PV systems. From the small rooftop system with a few modules to medium-sized systems on commercial roofs to large solar parks - PV*SOL premium supports you with numerous tools for design and simulation.

The unique 3D visualization is the highlight of PV*SOL premium. You can visualize all common types of systems in 3D, whether roof-integrated or roof-mounted, whether on small angled roofs, large industrial halls or open spaces - with up to 7,500 mounted modules or up to 10,000 roof-parallel modules, and calculate the shading based on 3D objects. This enables you to achieve the highest reliability for your earnings forecast - because for an accurate income calculation, a realistic representation of the shading from surrounding objects is essential.

All other design types from PV*SOL are of course also available to you in PV*SOL premium. Choose the type of design that best suits you and your PV project! The detailed results provide information about the performance of your system at all times.

Whether calculating self-consumption, designing battery storage or integrating electric vehicles - with PV*SOL you can implement and present all customer wishes in no time at all.

You can use our extensive product database at any time. It currently includes over 21,000 PV modules, 5,100 inverters, 1,900 battery systems and many other products such as electric vehicles and performance optimizers.

It is updated regularly by the product manufacturers themselves, so that you can always work with the latest data.

You can generate high-quality project reports for your customers that can be configured and edited as required. Circuit diagrams with the necessary safety devices can also be created, e.g. for submission to the relevant authorities.

The current feed-in tariffs are already available in our database for the calculation of economic efficiency. Supplemented with the information on the system costs, you will receive a detailed and meaningful economic analysis of the system over 20 years. In a few minutes you will receive an initial offer that you can refine afterwards if the customer is interested.

Our technical support team and our online help support you with open questions, and in our forum you can put more complex questions to our team and other users of PV*SOL premium and quickly receive an answer.

Product highlights

More program details

Import of 3D models

3D models of different file formats can be imported to enter object data. This adds another important tool to the existing option of reading floor plans, cadastral maps and screenshots from web-based satellite maps (e.g. Google Earth) directly into the 3D visualization.

Module assignment in 3D view

The roof areas are covered with the maximum possible number of modules automatically, or manually by tracing the areas to be covered by PV. If required, PV*SOL premium can show you the annual radiation reduction (direct and diffuse radiation) for every point of the PV area and for each module.

Polymorphic interconnection in combination with optimizers

Flexibility has been significantly increased when interconnecting the modules that are automatically placed on an object. The new option of polystring interconnection means that completely different strings can be connected in parallel or in series to an MPP tracker. Even different modules in one string, e.g. defective modules that are no longer available, can be replaced with similar ones.

Optimization of the module interconnection

You decide whether you want to connect several module areas to one inverter or choose a separate inverter for each module area, or combine both. The current status of the system check for the complete interconnection, the individual inverters and the MPP tracker is displayed at any time in the interconnection window.

Current online databases

In our extensive product databases you can currently find data records of over 21,000 PV modules, 5,100 inverters, 1,900 battery systems and many other products such as electric vehicles and performance optimizers, which are updated by the respective manufacturers. With our online databases, you can easily make your own products available to others.

Detailed project report

Create comprehensive project reports with simulation results and technical details in 22 languages and export them as Word or PDF documents. For a professional appearance, you can add your company logo to the title page and specify which content should be shown in the report.

Grid-connected systems with battery storage

Degign your own battery storage system by selecting the batteries used and defining the battery inverter and charging strategy. Alternatively, you can charge battery systems from leading manufacturers.

Electric vehicles

Select one or more electric vehicles that are simulated in combination with the photovoltaic system. By entering the daily mileage and the downtimes, PV*SOL calculates how much PV energy can be used to charge the electric vehicles.

Summary of results

The detailed results overview contains representations of the simulation results, the results of cost-effectiveness and a detailed tabular energy balance with all the gains and losses that occur. Carpetplots immediately provide you with an annual overview of individual results.

Circuit diagram

PV*SOL supports your system design with a freely configurable circuit diagram. Both the string cable losses and the AC and DC cable losses per inverter can be determined. Numerous safety devices such as fuses, switch disconnectors and surge protection can be easily added.

Thermal System

Use your solar energy to support the boiler in the thermal system as heating supply using a heating rod or a simplified model of a air-water heatpump.

Other features

Choose which models you want to use for diffuse radiation and radiation on the inclined surface. The U-I and U-P characteristics for each time step can be produced when required. Exchange your user ID to share self-created products within your company.
