What is GeoT*SOL
GeoT*SOL is a solar design and simulation application focused on planning photovoltaic systems with an emphasis on 3D site modeling and shading analysis. It is used by PV designers and engineers to evaluate system layout options and estimate energy yield based on location-specific conditions. The product is positioned as a design workflow that combines CAD-style modeling with PV performance calculations, supporting early-stage feasibility through detailed design.
3D terrain and shading modeling
GeoT*SOL centers on building a 3D representation of the site to evaluate horizon effects, near-field shading, and terrain influences. This supports more defensible layout decisions than workflows that rely primarily on simplified obstruction inputs. It is particularly relevant for complex sites where shading and topography materially affect yield estimates.
Integrated design-to-yield workflow
The product combines layout-oriented design steps with PV performance simulation in one environment. This reduces the need to export between separate CAD tools and yield calculators for common iterations. It can help teams keep assumptions (geometry, shading, orientation) aligned with the energy model during revisions.
CAD-style drafting for PV layouts
GeoT*SOL includes CAD-like capabilities for placing and arranging PV components within a modeled site context. This supports producing design artifacts that are closer to construction-ready layouts than purely analytical tools. It can be useful for teams that want a single tool for both geometric planning and performance evaluation.
Less standardized than dominant tools
Many organizations standardize on a small set of widely adopted PV design and simulation platforms, which can affect collaboration and handoffs. If partners or clients expect deliverables in specific formats or from specific tools, GeoT*SOL may require additional translation steps. This can add friction in multi-party projects.
Learning curve for 3D workflows
Building accurate 3D site models and configuring shading scenarios typically requires more user training than 2D or template-driven approaches. Teams may need defined modeling standards to keep results consistent across designers. Without that, outputs can vary based on user technique and input quality.
Integration and export constraints
Solar design teams often depend on integrations with CAD/BIM, CRM, proposal, and project documentation systems. If GeoT*SOL’s import/export options do not match an organization’s existing toolchain, users may rely on manual re-entry or intermediate file conversions. This can slow iteration cycles and increase the risk of versioning errors.
