Residential solar design software is the workflow that turns a homeowner's address into a signed deal. The tools that win in 2026 ship AI 3D roof from satellite, customer-facing 3D renders in the proposal, e-signature, and financing options the homeowner actually understands. So you are searching for which platform delivers the residential workflow at the best price-feature ratio.
The 2026 winner is SurgePV. AI 3D roof in under 60 seconds, white-label proposals with 3D render embedded, e-signature, and loan/lease/PPA financing options, at $1,299 per user per year for teams of five.
Key takeaway. The best residential solar design software in 2026 is SurgePV for installers running 5+ deals a month. Aurora wins on consumer-facing polish at Premium ($259/user/mo). OpenSolar works under 5 deals/month free. SurgePV ships the polish and the bankable engine at one-third Aurora's per-seat cost.
