Selecting a tool that matches reporting speed but not the required modeling control depth
Aurora Solar delivers proposal-focused reporting, but deep custom modeling controls are less granular than desktop simulators, which can slow work when teams require advanced loss decomposition standards.
Assuming all tools validate complex shading setups equally fast
OpenSolar produces consistent scenario reports, but complex shading setups take longer to validate than simplified horizon inputs, which can extend engineering timelines when shading is intricate.
Overlooking how much the final fidelity depends on input data quality and modeling settings discipline
Solargis improves consistency through geospatial terrain and obstruction context, but fidelity depends on input data quality and modeling settings discipline, so inconsistent input preparation creates inconsistent yield outputs.
Building governance and automation expectations on a tool with limited automation depth
Solar Monkey supports configuration reuse and quick exports, but API depth for automation is limited compared with advanced modeling suites, which can block heavy multi-project governance.
Expecting broad interoperability when the workflow is strongly hardware-constrained
SolarEdge Designer and SMA Sunny Design enforce inverter and optimizer or inverter-centric design constraints, which can limit interoperability when non-matching component models drive the study.
