Maximum Allowable Design Size
5MW Building Blocks
The advertised maximum system size for a layout in HelioScope is 5MW. Most utility scale HelioScope users will design a representative building block of 2 - 3 MW and multiply the results up to the total size.
HelioScope models the performance of every single module for every hour of the day, while traditional modeling software only simulate a single module or inverter and multiply up to the total system size. As a result, a 2MW design in HelioScope multiplied up to 50 MW still has significantly more granularity than traditional modeling software.
Pushing the Limits
In some cases, HelioScope users will try to push the limits of the software and design larger than 5MW. It is technically possible to exceed a 5MW layout, and HelioScope will simulate the production of arrays up to 15MW in total size. However, systems this large can run into difficulties such as slow simulation speed, CAD exports failing, and layout images not rendering among others. Unless designing very simple arrays, it is best to break designs down into easily manageable blocks to retain HelioScope's full functionality.
Please note, HelioScope has not been tested for use on systems larger than 5MW so designs above that range may not allow CAD exporting. In addition, the HelioScope support team will not be able to provide guidance on designs above 5MW.
