Software provider Vela Solaris launched version 6 of the simulation software Polysun. Not only did Polysun 6 get a facelift; it comes with new features that ease the daily work of solar system planners. The new PV Rooftop Planner, the insightful Simulation Analysis tool and more innovations.

PV rooftop planner including automatic or manual stringing

In addition to yield predictions and inverter setup, the new version of Polysun enables the optimal PV module layout on the roof surface. Developed by Vela Solaris in close cooperation with SolarGeo3D, this new feature allows the user to place PV modules both automatically and manually. In a typical operation sequence, after the roof shape has been determined, modules are placed in an optimal way to either cover the available roof surface completely or with the given number of modules. For inverter setup, string allocation is also calculated and displayed. Module placement and string allocation can be easily edited manually at any time. As a result, you will get an optimized roof plan and obtain accurate yield predictions generated by Polysun. Several roof surfaces with different orientations can be combined easily on one system calculation.

Simulation analysis
A guaranteed "wow" effect for experienced Polysun Designer users: Polysun 6 allows them to carry out a graphically-aided simulation analysis, i.e. for each calculated time step, pipe flow rates and temperatures as well as other interesting values are displayed on the design area. When the simulation is completed, a slider control enables the user to analyse the whole year.

Programmable controllers
The new version 6 of Polysun includes important new features also in the field of solar thermal energy. It is now possible for the user to employ programmable controllers, enabling the definition of operating statuses according to controller inputs as well as to describe controller output values for each operating status. The control logic is defined by means of formulas that are comparable to the calculation formulas used in spreadsheets such as Excel.

Rechargeable batteries for PV self-consumption optimization
With the goal of optimizing PV self-consumption Polysun is now equipped with a new calculation model for rechargeable batteries: the battery is charged when the amount of power produced exceeds that used. Therefore, if required, the solar energy produced on your roof can be used at a later time.
