Solar PV design done right

Designing customized solar systems is a complicated task that requires solar engineers to take into account a multitude of factors, such as size and orientation of the system, number and usage time of electrical appliances, general climate and sun radiation of the system, local grid distribution and capacity and much more.

PV*SOL helps you do all that and more so you can focus on designing efficient and economic rentable photovoltaic systems. All from within a practical and user-friendly interface.

Top Features

Shading

3D Shading Analysis

A real-world representation of the shading from surrounding objects is extremely important for precisely calculating yields.

With PV*SOL premium you can visualize all roof-integrated or mounted systems - even on the ground - with up to 5,000 modules in 3D and calculate shading on the basis of 3D objects.

Feature available only in PV*SOL premium

Battery Storage

Battery Storage Systems

Plan your own battery storage system by quickly and easily selecting the batteries used and defining the battery inverter and charging strategy.

Alternatively, you can load complete battery storage systems from leading manufacturers. Due to the reliable and validated simulation models, you can make even more precise statements about the self-consumption and self-sufficiency rates.

maps

Maps Import

Buildings and objects can be created quickly and easily by using floor plan drawings and satellite maps. It must be drawn only the respective contours and then the building can be extruded by entering the height.

Thus, for example, any building shapes with a flat roof can be produced.

electric vehicles

Electric Vehicles

In PV*SOL premium you can select an electric car from the database. Then, after entering the corresponding daily mileage for the car, PV*SOL premium calculates how much solar energy needs to be used in order to charge the car.

The software also calculates the cost per 100 kilometers driving distance, with and without the use of photovoltaics.
