Coverage includes Aurora Solar, Sunnova Solar Design, SolarEdge Designer, OpenSolar, PVWatts, HOMER Energy, SAM, SolarGIS, Solargraf, and Aurora Go. Each section maps specific tool strengths to concrete buying criteria for solar estimating teams.
What Is Solar Estimate Software?
Solar estimate software turns site and design inputs into proposal-ready outputs, including energy production figures, system configurations, and customer documents. It solves the time cost of manual spreadsheet estimating and the accuracy risk created by inconsistent assumptions across sales and design. Many teams use browser-based design and proposal generation like Aurora Solar to produce visuals directly from a modeled roof. Contractors using standardized residential workflows can also rely on OpenSolar to convert sizing assumptions into structured customer proposals.
Key Features to Look For
The right feature set depends on whether the workflow needs customer visuals, standardized residential quotes, or engineering-grade simulation results.
Browser-based 3D roof modeling with proposal generation
Aurora Solar supports browser-based 3D solar design and proposal generation from a modeled roof, which speeds customer-ready visual presentations. This workflow also ties shading and design constraints to estimate outputs so proposals reflect real site limits instead of generic assumptions.

Sunnova Solar Design focuses on customer-facing solar design and proposal output generation for residential estimates. Solargraf complements this need with fast, consistent client-ready proposal report generation from estimate inputs.
Hardware-compatible system configuration driven estimating
SolarEdge Designer generates estimates using SolarEdge component data and layout inputs, which keeps proposals aligned with compatible inverters and module selections. This reduces ambiguity in procurement documentation when teams standardize on SolarEdge hardware.
Structured estimate builder for consistent deal-to-deal quoting
OpenSolar provides an estimate builder that converts sizing inputs into structured customer proposals while maintaining project and document handling. This supports consistent estimation across multiple residential deals using configurable estimate options.
Location-based PV energy estimation with monthly breakdown
PVWatts calculates PV energy estimates using NREL location inputs and system assumptions, including tilt and azimuth. It delivers monthly and annual generation outputs so feasibility screening and quick proposal back-of-napkin work stay fast.
Time-series or dispatch and lifecycle techno-economic simulation
SAM delivers time-series PV performance plus dispatch and bankability-oriented techno-economic reporting for rigorous scenario feasibility studies. HOMER Energy extends that capability into microgrid simulation with dispatch behavior and lifecycle cost outcomes across PV and storage scenarios.
How to Choose the Right Solar Estimate Software
The fastest path to the right tool is choosing outputs that match the workflow stage where estimates must become customer-ready or bankability-ready.
Match the tool to the exact output stage needed
If customer presentations require visuals built from roof geometry, Aurora Solar is designed for browser-based 3D roof modeling and proposal generation. If the sales team needs customer-facing residential documents aligned to Sunnova’s process, Sunnova Solar Design emphasizes proposal outputs over deep spreadsheet customization.
Decide whether estimating is standardized or engineering-configured
If quoting relies on standardized residential scenarios, OpenSolar focuses on configurable estimate options that turn sizing inputs into structured proposals quickly. If the business standardizes on a specific hardware ecosystem, SolarEdge Designer uses SolarEdge system configuration documentation so electrical design details stay consistent.
Select the modeling depth based on project complexity
For quick feasibility screening and rapid production assumptions, PVWatts provides location-based energy estimates with monthly and annual outputs. For microgrid or storage-including designs that require dispatch and lifecycle outcomes, HOMER Energy produces simulation-driven energy balance, costs, and operating schedules.
Use simulation tools when scenario feasibility must stand up to scrutiny
For time-series PV performance with degradation and dispatch and integrated techno-economic analysis, SAM targets engineering-grade system estimation across many scenarios. For multi-location developer workflows driven by geography and mapping, SolarGIS uses GIS-driven solar resource modeling to produce yield estimates tied to site mapping.
Confirm field efficiency with the input collection workflow
If quoting starts in the field and must generate consistent proposal outputs quickly, Aurora Go emphasizes mobile and field workflows with scenario-based options from the same project inputs. This reduces the time spent hunting for estimate fields by guiding quote turnaround through focused workflow steps.
Who Needs Solar Estimate Software?
Solar estimate software benefits teams that turn design inputs into repeatable proposals, from sales document generation to scenario-grade engineering outputs.
Solar installers and sales teams producing customer-ready visuals at scale

Engineering teams running rigorous system feasibility studies or microgrid scenarios
SAM supports deep time-series PV performance plus dispatch and degradation modeling and integrated techno-economic reporting for scenario feasibility work. HOMER Energy expands that requirement into PV and storage microgrid simulation with dispatch and lifecycle techno-economic results suitable for engineering-grade comparison.
Common Mistakes to Avoid
Several predictable buying mistakes appear across solar estimate workflows built around the reviewed tools.
Choosing a simulation tool for simple quoting speed
SAM and HOMER Energy both require modeling discipline and parameterization, which slows down estimate-first teams that only need monthly energy numbers and proposal documents. PVWatts provides fast location-based estimates with monthly and annual breakdown that avoids unnecessary setup when shading and string-level effects are not modeled.
Ignoring hardware standardization requirements for electrical consistency
SolarEdge Designer produces estimates tied to SolarEdge component compatibility, so mixed vendor estimating creates workflow complexity when designs deviate from common SolarEdge reference configurations. Teams that need vendor-agnostic flexibility should evaluate tools like OpenSolar and Aurora Solar, which are not limited to a single hardware ecosystem.
Over-relying on generic energy assumptions when layout and shading drive results
PVWatts uses assumptions that do not directly model shading, array layout effects, or string-level impacts, which can produce misleading production expectations for complex sites. Aurora Solar includes shading and design constraints in its modeled workflow so proposals reflect real site limits and improve accuracy.
Underestimating the input-quality dependency of 3D proposal workflows
Aurora Solar’s 3D design and proposal outcomes depend on accurate roof measurements and photos, so poor inputs lead to weaker estimate visuals and constraint handling. Aurora Go also benefits from consistent project inputs because scenario-based options work best when the same site details populate the quote fields cleanly.
How We Selected and Ranked These Tools
we evaluated each tool on three sub-dimensions: features with a weight of 0.4, ease of use with a weight of 0.3, and value with a weight of 0.3. The overall rating for each tool is the weighted average using overall = 0.40 × features + 0.30 × ease of use + 0.30 × value.
