Solargraf
vertical specialistSolar sales software for system design, proposals, financing, and installation workflows.
Module-level placement feeding electrical string sizing and inverter matching in the same estimate workflow.
Solargraf is a solar estimate workflow tool that turns roof geometry inputs into module-level placements and ties those placements to string sizing and inverter matching decisions. Annual energy yield outputs can be generated in a repeatable way so sales teams can rerun scenarios when equipment selections or utility rate modeling inputs change. The equipment library and layout workflow reduce manual recalculation during iterative proposal revisions, and exports support PDF and CAD handoff needs for downstream permitting steps.
A key tradeoff is that deeper electric design artifacts like a detailed single-line diagram depend on how the project data and export bundle are set up in the workflow configuration. Solargraf fits best when teams need consistent proposal-to-export output for many sites and want to reduce variation between estimators without building custom calculation code.
A second tradeoff is that automation coverage can be limited for nonstandard permitting packages that require specific attachment structures beyond Solargraf exports. Solargraf works well when proposals follow a standard internal template and when operational governance focuses on repeatable configuration rather than heavy approval routing controls.
- +Module-level layout connects to electrical sizing decisions
- +Equipment library speeds consistent module and inverter selection
- +PDF and CAD export supports proposal and permit handoff
- +Scenario reruns keep production estimates aligned to inputs
- –Single-line diagram detail depends on workflow configuration
- –Nonstandard permit package attachments require extra process steps
- –Governance controls may be lighter than enterprise quote platforms
- –Custom edge-case calculations can require manual estimator time

Pylon
vertical specialistSolar sales software for proposals, project workflows, and installer operations.
Estimate configuration propagation keeps changes tied to the project, so revised quotes update without rebuilding prior assumptions.
Pylon fits teams that need estimate consistency across sales and engineering handoffs, because it keeps project assumptions tied to system configuration choices. It covers core estimating steps such as photovoltaic sizing inputs and output generation that teams can export for downstream proposal review. API access supports integration patterns for CRM handoffs and internal tooling that need to create or update estimates programmatically. A key differentiator is how configuration changes propagate through a project so sales iterations do not require rebuilding the estimate from scratch.
A tradeoff appears with advanced electrical detail and permitting set depth, since some workflows still rely on manual follow-up for interconnection application and permit plan packaging. Pylon is most useful when estimates must be revised frequently due to equipment availability, updated utility rate assumptions, or site data corrections between customer meetings.
- +API-based estimate creation supports CRM and workflow automation
- +Equipment library reduces repeat entry errors across jobs
- +Configuration propagation speeds quote revisions between revisions
- +Export outputs match sales review and customer presentation needs
- –Electrical and permitting documentation depth may need external tooling

How to Choose the Right solar estimate software
This guide covers solar estimate software tools used to generate proposal-ready designs, production estimates, and permit-style exports across Solargraf, Pylon, Solar Monkey, Aurora Solar, OpenSolar, PVcase, Scanifly, SolarEdge Designer, EasySolar, and PV*SOL.
The sections explain what each tool type does in real workflows, what capabilities to evaluate, and where implementations tend to fail for sales and design teams.
Solar estimate software that turns roof and equipment inputs into proposal-ready designs
Solar estimate software combines PV system sizing inputs, equipment library selections, and roof geometry inputs to produce proposal deliverables that tie design assumptions to production estimate outputs. Tools like Solargraf generate estimates from site inputs using an equipment library and also support module-level layout workflows that connect directly to electrical string sizing and inverter matching.
Teams use these tools to reduce rework between design and document output, to keep revisions consistent after assumption changes, and to package CAD or PDF deliverables for internal review and permitting handoff. Aurora Solar and OpenSolar show the same core pattern with geospatial or roof plane mapping that drives module layouts and performance assumptions into proposal outputs.
Evaluation checklist for solar estimate tools that drive engineering and proposal outputs
Solar estimates fail most often when tool outputs do not stay synchronized with the assumptions used to calculate them. The features below focus on where synchronization, traceability, and automation usually break in practice.
Each capability is mapped to concrete strengths seen in specific tools, like Solargraf’s module placement feeding string sizing or Pylon’s API-driven configuration propagation.
Module-level placement that feeds electrical string sizing and inverter matching
Solargraf connects module placement to electrical sizing decisions inside the same estimate workflow, so layout and inverter matching evolve together during revisions. PV*SOL also ties module layout and shading-aware production estimation to annual energy yield, including inverter matching and DC-to-AC context.
Equipment library controls for consistent module and inverter selections
Pylon and Solargraf reduce repeat entry errors by using an equipment library for module and inverter combinations across jobs. OpenSolar, PVcase, and SolarEdge Designer also rely on library-driven configuration so proposal outputs remain consistent after edits.
Geospatial or roof plane mapping that drives module layouts and synchronized visuals
Aurora Solar uses geospatial roof mapping to drive module-level layouts while keeping proposal visuals synchronized with production estimate inputs. OpenSolar and PVcase also anchor downstream outputs to roof plane mapping geometry from a single set of inputs.
Configuration revision propagation with API-driven estimate creation
Pylon keeps estimate configuration changes tied to the project so revised quotes update without rebuilding prior assumptions. Pylon also supports API-based estimate creation for CRM and workflow automation, while Solar Monkey focuses on regenerating proposal documents from reused prior assumptions.
Proposal-to-document exports aligned to permit-style packaging
Tools like Solargraf and OpenSolar export proposal artifacts in CAD and PDF formats to support permit-ready packaging and customer review. Scanifly outputs standardized CAD and PDF exports from roof mapping workflows and also tracks changes during proposal preparation.
Shading analysis and yield logic with traceable input quality dependencies
SolarEdge Designer combines roof-plane mapping with shading analysis to drive SolarEdge-specific annual yield outputs inside one flow. PVcase improves annual energy yield estimates for complex roof cases via shading analysis, while Aurora Solar’s shading and roof mapping accuracy depends on imagery quality.
Decision path for choosing the right solar estimate workflow tool
Tool selection should follow the workflow that needs the most synchronization. Some teams need API-first automation into CRM workflows, while other teams need a geometry-to-document pipeline that stays consistent across revisions.
The decision steps below branch based on the actual operational requirement so the selected tool matches the delivery pipeline.
Start with the output type and handoff format that the business needs
If permit-style packaging in CAD and PDF drives the workflow, Solargraf and OpenSolar provide CAD and PDF export outputs designed for proposal and permit handoff. If standardized CAD and PDF exports plus tracked change records are the priority, Scanifly drives roof mapping outputs into standardized export packages.
Choose the geometry input strategy that matches data collection in the field
If imagery-based geospatial mapping is available and needs to drive module layouts, Aurora Solar’s geospatial roof mapping drives module-level layouts and synchronized proposal visuals. If design teams rely on roof plane mapping with azimuth and tilt inputs, OpenSolar and PVcase centralize geometry inputs that feed downstream performance assumptions.
Pick the automation posture based on how estimates enter and update
If estimate creation must be automated from external systems, Pylon’s API-based estimate creation and configuration propagation are built for CRM and workflow automation. If internal users mainly need fast document regeneration after assumption edits, Solar Monkey’s proposal regeneration workflow reuses prior assumptions to update output documents.
Decide how much electrical modeling depth must be handled inside the tool
For workflows that require module placement to directly drive electrical string sizing and inverter matching, Solargraf provides that module-level linkage inside the estimate workflow. For teams that prefer detailed simulation and inverter matching with shading-aware yield calculations, PV*SOL includes string sizing and inverter matching and exports CAD and PDF deliverables.
Validate shading and yield performance requirements against site imagery and complexity
If SolarEdge hardware alignment is required and shading-aware annual yield must follow SolarEdge-specific logic, SolarEdge Designer ties roof-plane mapping and shading analysis to SolarEdge annual yield outputs. If obstruction complexity is common and shading depth must remain reliable, PVcase improves annual energy yield estimates using shading analysis, while OpenSolar’s shading analysis feels limited for complex obstruction modeling.
Which teams benefit from solar estimate software workflows
Different solar estimate tools map to different delivery models. Some tools prioritize repeatable proposal exports for large sales pipelines, while others prioritize API-driven estimate iteration or roof imagery-to-document automation.
The segments below match the stated best_for audiences from the tool set.
Sales and engineering teams needing repeatable proposal exports across many roof sites
Solargraf fits teams that need repeatable proposal exports tied to equipment library selections and module-level placement workflows that feed electrical sizing decisions. Its CAD and PDF exports support proposal and permit handoff at scale.
Sales engineering teams needing API-driven estimating with consistent configuration control
Pylon fits teams that want configuration propagation so revised quotes update without rebuilding prior assumptions. Its API-based estimate creation supports CRM and workflow automation where estimates originate outside the tool.
Teams that need proposal regeneration that keeps assumptions consistent across document revisions
Solar Monkey fits organizations that tie estimate inputs to proposal-ready document output and need fast regeneration after input changes. Its regeneration workflow reuses prior assumptions so revisions stay consistent.
Design-first teams that rely on geospatial or roof-plane mapping to drive layouts and visuals
Aurora Solar fits teams that use geospatial roof mapping to synchronize module-level layouts with proposal visuals and irradiance-driven production estimates. OpenSolar and PVcase fit teams that centralize roof plane mapping geometry to drive downstream outputs from a single geometry input.
Installers needing document exports driven directly from roof imagery with change tracking
Scanifly fits teams using roof imagery and wanting configurable proposal workflows that output standardized CAD and PDF exports. Its audit log style change tracking helps review assumptions over time.
Where solar estimate tool projects break in real deployments
Most failures come from mismatched expectations between what the tool models and what the business needs for electrical, permitting, or automation integration. Other issues come from setup choices that slow down edge-case work.
The pitfalls below map to concrete cons seen across the tool set and include corrective direction.
Assuming permit documentation depth is fully covered inside the estimate tool
Solargraf and Aurora Solar support CAD and PDF export workflows, but nonstandard permit package attachments can require extra process steps in Solargraf and complex permit set workflows may need external handling in Aurora Solar. For thin coverage of electrical and permitting documentation depth, Pylon also depends on external tooling when the inputs are incomplete.
Underestimating governance and change-control requirements for edge-case configurations
Scanifly and PVcase can require governance discipline for complex estimate configurations and advanced setup, which can slow repeatability if teams skip upfront configuration. Solargraf also notes lighter governance controls than enterprise quote platforms, so teams needing granular enterprise-style quote governance may need extra internal controls around configurations.
Treating shading and yield outputs as independent of imagery quality and workflow setup
Aurora Solar’s shading and roof plane mapping accuracy depends on imagery quality, and OpenSolar’s geospatial imagery imports require careful alignment before edits. Scanifly also ties shading analysis depth to captured imagery quality, so low-quality roof imagery creates unreliable shading inputs.
Choosing a tool for electrical complexity without verifying its modeling depth in the required workflow step
SolarEdge Designer is constrained to SolarEdge-centric design logic, and complex sites still require manual verification of electrical assumptions. OpenSolar’s shading depth feels limited for complex obstruction modeling, and PV*SOL’s module-level and string-level accuracy depends on upfront equipment and layout configuration.
Expecting developer-grade integration and automation coverage from tools not built for that posture
Pylon offers API-based estimate creation for automation, while PV*SOL and SolarEdge Designer limit API and automation surface for third-party systems. EasySolar’s workflow is focused on proposal calculation and PDF export for client delivery, so it does not expose interconnection application steps as a configurable workflow.
How We Selected and Ranked These Tools
We evaluated Solargraf, Pylon, Solar Monkey, Aurora Solar, OpenSolar, PVcase, Scanifly, SolarEdge Designer, EasySolar, and PV*SOL using a consistent criteria set tied to what teams actually need from a solar estimate workflow. Features carried the most weight at 40% because estimate correctness depends on how roof geometry, equipment library choices, electrical decisions, and export outputs are connected, while ease of use and value each accounted for 30% because day-to-day iteration time affects quote throughput. Each tool also received a score for the practical fit of its workflow automation and document exports to the named use cases in the provided descriptions.
Solargraf separated itself because its module-level placement feeds electrical string sizing and inverter matching in the same estimate workflow and it also pairs that linkage with CAD and PDF export for proposal and permit handoff, which raises both feature strength and day-to-day usability in estimate revisions.
