Quick Verdict
Our Verdict
PVsyst and PV*SOL are both solid desktop simulation tools, but they serve different markets. PVsyst is the choice for international bankable reports and utility-scale projects. PV*SOL is stronger for European residential and small commercial projects with battery, EV, and heat pump integration. Both are desktop-only and lack design, proposal, and engineering capabilities. SurgePV offers a cloud-based alternative that combines simulation with the full project workflow.

Simulation Depth
Both PVsyst and PV*SOL are serious simulation tools, but they emphasize different aspects of energy system modeling.
PVsyst: Bankable by Default
PVsyst’s simulation engine has been the reference standard for project financing for over 30 years. Its detailed loss chain models every component from irradiance transposition to AC grid injection. The software’s P50/P75/P90 probability distributions are the format that most international banks and investment funds require.
PVsyst connects to 15+ meteorological databases and supports complex array configurations including trackers, bifacial modules, and heterogeneous orientations. For multi-MW projects where simulation accuracy directly affects financing terms, PVsyst is the default choice.
PV*SOL: Energy System Integration
PV*SOL takes a broader view of the energy system. While its PV simulation is comparable to PVsyst for residential and small commercial projects, PV*SOL’s real strength is in modeling integrated energy systems. The software includes built-in modules for battery storage optimization, EV charger load profiles, and heat pump coupling.
For a German installer designing a residential system with solar panels, a battery, an EV wallbox, and a heat pump, PV*SOL models the complete energy flow between all four components. PVsyst treats the PV system in isolation and cannot model these interactions.
PV*SOL’s 3D visualization is also more developed than PVsyst’s basic 3D scene editor. You can build detailed roof models, place obstructions, and run 3D ray-tracing shade analysis directly in the software.
Where PV*SOL falls short is in international bankability. Outside Europe, most lenders do not accept PV*SOL reports for financing purposes. For utility-scale projects, PV*SOL’s simulation capabilities are less developed than PVsyst’s.
3D Design & Visualization
PVsyst 3D Modeling
PVsyst includes a basic 3D scene editor for modeling near-shading objects. You can place simplified building structures, trees, and fences to calculate shade impact on the array. This is functional for shade analysis purposes but is not a design tool. You cannot create detailed roof models or perform visual panel placement in PVsyst.
PV*SOL 3D Design
PV*SOL Premium includes a proper 3D design environment where you can model roof structures, dormers, chimneys, and surrounding obstacles in three dimensions. Panel placement happens directly on the 3D roof model, with real-time shade visualization showing how nearby objects affect each module throughout the year.
For residential installers who want to visualize the system before installation and show customers what the array will look like, PV*SOL’s 3D capabilities are a clear advantage over PVsyst.

Best Alternative: SurgePV
Both PVsyst and PV*SOL are respected simulation tools, but they share the same fundamental limitation: they’re desktop-only software that only handles simulation. Neither produces proposals, SLDs, three-line diagrams, or permit packages. Teams using either tool still need additional software for the rest of their project workflow.
SurgePV takes a different approach by combining everything in one cloud-based platform:
- Design: AI-powered cloud-based design on satellite imagery, accessible from any browser on any operating system
- Simulation: 8760-hour energy yield analysis with P50/P75/P90 confidence levels and detailed loss modeling
- Proposals: Professional web and PDF proposals with global financial modeling, multi-currency support, and flexible financing structures
- Engineering: Native SLD generation, three-line diagrams, automatic wire sizing, BOM, and permit package export
- Scale: Handles residential through 5 MW commercial projects without separate tool configurations
At $1,499/yr for 3 users, SurgePV replaces the entire toolchain that PVsyst or PV*SOL users typically need: simulation software + design tool + proposal software + AutoCAD for engineering. There’s no Windows dependency and no desktop installation.

Frequently Asked Questions
Is PVsyst more accurate than PV*SOL?
Both are respected simulation tools. PVsyst is more widely accepted for bankable reports by international lenders. PV*SOL is well-regarded in the European market, particularly Germany, and offers comparable accuracy for residential and small commercial systems.
Does PV*SOL have 3D design capabilities?
Yes. PV*SOL Premium includes full 3D visualization with shade analysis, allowing you to model roof structures, nearby buildings, and vegetation. PVsyst has basic 3D scene modeling but is not a design tool.
Which is better for battery storage modeling?
PV*SOL has stronger battery storage modeling with support for EV chargers and heat pumps in addition to batteries. PVsyst models battery systems but focuses primarily on grid-connected PV simulation.
Is PV*SOL cheaper than PVsyst?
PV*SOL Premium costs approximately $1,410 as a one-time purchase plus annual maintenance. PVsyst costs $800-1,400/yr as an annual subscription. Over 3+ years, PV*SOL’s one-time model is typically cheaper.
What’s a better alternative to both PVsyst and PV*SOL?
SurgePV offers cloud-based design, simulation, proposals, and engineering in one platform at $1,499/yr. Unlike both PVsyst and PV*SOL, it runs in the browser, generates proposals, and includes native SLD generation.
Can PV*SOL produce bankable reports?
PV*SOL produces detailed simulation reports that are accepted by many European banks and utilities. However, for international project financing, especially in North America and Asia-Pacific, PVsyst reports carry more weight with lenders.
