Vela Solaris has introduced ‘Polysun 6’ PV planner software that includes new features that ease the daily work of solar system planners as well as being enhanced to provide simulation analysis of battery storage requirements for self-consumption.
Both residential and commercial-scale rooftop PV systems are becoming increasingly complex to plan due to the need to fully maximise energy output as well as cater for the growing need to include analysis requirements dictated by battery storage systems.
In addition to yield predictions and inverter setup, the new version of Polysun 6 is claimed to provide 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 operational sequence, after the roof shape has been determined, modules are placed in a way to optimally cover the available roof surface either completely or with the given number of modules. For inverter setup, string allocation is thus calculated and displayed. Module placement and string allocation can be easily edited manually at any time, intended to provide an optimised roof plan and obtain accurate yield predictions.
Commercial and residential roof planning of PV systems.
Polysun 6 is now equipped with a new calculation model for rechargeable batteries: the battery is charged when the amount of power produced that exceeds that used. The solar energy produced on the roof can then be used at a later time.
February 2013 onwards.
