AI Solar Sales & Design Software Compared 2026: Faster Proposals Without Site Visits
A deep dive into AI-powered solar design, quoting, and sales software. Compare Aurora Solar, OpenSolar, Solargraf, and Demand IQ — tools that auto-design from aerial imagery and dramatically speed up proposals.
In the solar industry, every proposal demands a site visit, roof measurement, shading analysis, and quote — and the lead time to close heavily influences win rates. In 2026, AI is fundamentally reshaping this design-and-sales process. Tools now recognize roof geometry from aerial or satellite imagery and compute optimal panel layouts and annual energy production in minutes. This article compares the leading AI solar design and sales platforms.
How AI Solar Design Works
These tools analyze high-resolution aerial imagery, satellite photos, and LiDAR data with computer vision to automatically extract roof area, pitch, orientation, and obstructions. They then simulate shading from surrounding buildings and trees in 3D and calculate irradiance by time of day and season. Combined with weather data, they accurately predict annual production and electricity-bill savings. Because design and quoting happen from the office without a site visit, proposals per rep increase substantially.
Tool Comparison
Aurora Solar
A high-accuracy design platform widely considered the industry standard. Its LiDAR-based 3D modeling and shading analysis are highly precise, and it's broadly used for large residential and commercial projects. It covers everything from design to proposals, quotes, and financing options.
OpenSolar
Growing fast on a disruptive pricing model that offers core features for free. You can design, build 3D proposals, quote, and e-sign at no cost, with monetization via hardware sales commissions — a low barrier for small installers.
Solargraf
An easy-to-use design and quoting tool under Enphase. Its strengths are automatic permit-package generation and remote roof design, making it a fit for speed-focused sales teams.
Demand IQ
Specializes in customer-facing instant quotes. Prospects enter an address and get a rough self-serve estimate, automating lead capture and inbound sales.
Scanifly
Focuses on automating site surveys and design using drone capture data, valued for precise design of complex roofs and commercial facilities.
Benefits
- Shorter proposal lead times: Design and quoting that took days now takes minutes.
- Higher close rates: Visual 3D proposals and savings simulations boost customer confidence.
- Lower survey costs: Eliminate first visits; only send crews to promising deals.
- Fewer design errors: Automatic measurement and code checks prevent post-install issues.
Considerations Outside North America
Most of these tools assume North American electricity rates, incentives, and weather data, so support for local feed-in tariffs, utility-specific buyback terms, and regional irradiance data can be a gap. In many markets, pairing them with locally focused simulation tools or manufacturer-provided design software is the practical path. Currency swings and imported-equipment price volatility also need to be built into quotes.
Conclusion
AI solar design software is a powerful lever that lifts both proposal speed and close rate at once. Build a workflow where self-serve quoting tools generate leads, AI design produces fast proposals for promising deals, and site visits are reserved for final verification — and even a lean team can maximize proposal volume.
