What is T*SOL
T*SOL is a solar PV design and simulation application used to model photovoltaic systems and estimate energy yield. It supports project workflows such as system layout, component configuration, and performance analysis for residential, commercial, and utility-scale scenarios. The product is typically used by solar designers, engineers, and EPC teams that need bankable-style modeling outputs and documentation for proposals and engineering review. It is positioned as a desktop-style engineering tool rather than a general-purpose CAD platform.
PV performance simulation focus
The product centers on PV system simulation and yield estimation rather than only drawing or layout. This makes it suitable for feasibility studies, design validation, and comparing design variants (e.g., orientation, tilt, inverter sizing). Outputs are oriented toward engineering review and energy modeling deliverables. In this segment, that emphasis aligns with tools used for detailed performance analysis.
Design-to-analysis workflow
T*SOL combines system configuration with analysis in a single environment, reducing the need to export to separate modeling tools for basic yield calculations. Users can iterate on design parameters and quickly see impacts on production and losses. This supports early-stage design decisions and proposal engineering. It fits teams that want an integrated workflow rather than assembling multiple point tools.
Engineering-oriented reporting outputs
The software provides project documentation and calculation outputs intended for technical stakeholders. This can help standardize internal review and client-facing deliverables. Compared with lighter-weight layout tools, the reporting is typically more aligned with engineering assumptions and loss breakdowns. That can reduce manual spreadsheet work for common analyses.
Limited general CAD breadth
Although it supports design tasks, it is not a full general-purpose CAD system for broader drafting needs. Teams that require extensive 2D/3D drafting, multi-discipline coordination, or complex drawing standards may still need dedicated CAD software. This can introduce handoffs between tools for construction drawing sets. The CAD capabilities are best viewed as solar-design-oriented rather than universal.
Desktop deployment constraints
As a desktop-style engineering tool, collaboration features may be less native than cloud-first platforms (e.g., multi-user real-time editing, centralized project governance, browser access). Organizations with distributed teams may need additional processes for version control and file sharing. IT policies (installation, updates, licensing) can also add overhead. This can be a consideration versus web-based design environments.
Learning curve for modeling
Detailed simulation tools typically require users to understand modeling assumptions, loss factors, and component configuration to avoid inconsistent results. New users may need training to produce repeatable, reviewable outputs. Organizations may also need internal standards for assumptions and templates. Without that governance, results can vary across designers.
