✦ Lumen Take
HelioScope and OpenSolar provide two distinct operational approaches in the Design / Finance space. While HelioScope excels as a Physics-Based Simulation solution, OpenSolar is specialized as a Zero-Cost OS Model platform.
Switching from HelioScope to OpenSolar requires adjusting CAD-level shading accuracy tolerances and recalibrating NBT ROI modeling for NEM 3.0 compliance.
