Polysun 6: With its new PV Rooftop Planner, the optimal<br />
solar system is just a few clicks away<br />
San Francisco, February 20 th , 2013 – Software provider <strong>Vela</strong> <strong>Solaris</strong> launched<br />
version 6 of the simulation software Polysun. Not only did Polysun 6 get a<br />
facelift; it comes with new features that ease the daily work of solar system<br />
planners. The new PV Rooftop Planner, the insightful Simulation Analysis tool<br />
and more user friendly innovations are included in Polysun 6.<br />
PV rooftop planner including automatic or manual stringing<br />
In addition to yield predictions and inverter setup, the new version of Polysun enables the<br />
optimal PV module layout on the roof surface. Developed by <strong>Vela</strong> <strong>Solaris</strong> in close<br />
cooperation with SolarGeo3D, this new feature allows the user to place PV modules both<br />
automatically and manually. In a typical operation sequence, after the roof shape has been<br />
determined, modules are placed in an optimal way to either cover the available roof<br />
surface completely or with the given number of modules. For inverter setup, string<br />
allocation is also calculated and displayed. Module placement and string allocation can be<br />
easily edited manually at any time. As a result, you will get an optimized roof plan and<br />
obtain accurate yield predictions generated by Polysun. Several roof surfaces with different<br />
orientations can be combined easily on one system calculation.<br />
Figure 1: With Polysun 6 PV Rooftop Planner, the string allocation is optimized based on roof<br />
geometry and inverter allocation.<br />

Simulation analysis<br />
A guaranteed “wow“ effect for experienced Polysun Designer users: Polysun 6 allows them<br />
to carry out a graphically-aided simulation analysis, i.e. for each calculated time step, pipe<br />
flow rates and temperatures as well as other interesting values are displayed on the design<br />
area. When the simulation is completed, a slider control enables the user to analyse the<br />
whole year.<br />
Figure 2: Graphically-aided simulation analysis in the latest release of Polysun: temperatures and<br />
flow rates are displayed for each calculated time step.<br />
Programmable controllers<br />
The new version 6 of Polysun includes important new features also in the field of solar<br />
thermal energy. It is now possible for the user to employ programmable controllers,<br />
enabling the definition of operating statuses according to controller inputs as well as to<br />
describe controller output values for each operating status. The control logic is defined by<br />
means of formulas that are comparable to the calculation formulas used in spreadsheets<br />
such as Excel.<br />

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