Aurora Solar holds a deserved reputation as the premium AI-powered solar design platform for US residential installers. It’s also priced at an estimated $2,640–$6,000+/user/year (sales-quoted, not publicly listed), US-centric, requires AutoCAD for commercial SLD work, and lacks native support for carport, tracker, and East-West racking. For teams outside the pure-US-residential profile, the right alternative depends on which gap matters most.
This guide compares 6 Aurora Solar alternatives ranked by pricing transparency, international coverage, racking type support, and workflow integration.
When You Need an Aurora Solar Alternative
Aurora’s fit profile is specific: US residential installer with budget for premium tooling and no commercial/international/non-standard-racking pipeline. If you’re outside that profile:
- Operating internationally → SurgePV (9 languages, native multi-currency), OpenSolar (185 countries free)
- Commercial work needing SLDs → SurgePV (native NEC SLDs, no AutoCAD)
- Carport, tracker, or East-West projects → SurgePV, PVCase, HelioScope (Enterprise)
- Want pricing transparency → SurgePV, OpenSolar, HelioScope (all publicly priced)
- Mid-market budget ($1,500–$3,000/yr) → SurgePV, HelioScope, PVCase
- Free option → OpenSolar
The 6 Best Aurora Solar Alternatives
1. SurgePV — Best All-in-One Aurora Replacement
Best for: EPCs needing Aurora’s design quality without the premium price, US-centric limits, or AutoCAD dependency for commercial work.
SurgePV uses LiDAR-grade satellite data and AI-assisted roof detection comparable to Aurora’s industry-leading approach, with the additional capabilities Aurora lacks: native US SLD generation (no AutoCAD), full international workflow (9 languages, multi-currency proposals, regional grid codes), and all major racking types (carport, single-axis tracker, dual-axis tracker, East-West, ground-mount, rooftop). Pricing is custom per organization with transparent published tiers.
Pros: Comparable design quality + LiDAR roof modeling, native SLD, international coverage, all racking types, transparent pricing. Cons: Different CRM integration model — SurgePV uses standard API connections rather than Aurora’s Salesforce/HubSpot two-way sync. Pricing: Custom + transparent tiers, typically 30–50% lower than Aurora premium.

2. HelioScope — Best for C&I Simulation-First Workflow
Best for: Commercial & industrial designers prioritizing DNV GL-validated simulation accuracy.
HelioScope is browser-based with simulation accuracy within 1% of PVsyst (DNV GL validated). Strong for C&I work. Limits: 10-project monthly cap on Basic/Pro, 15 MW system size hard limit, no native BESS modeling, weak financial analysis (G2 5.2/10).
Pros: DNV GL validated accuracy, web-based, fast iterations, 8.9/10 G2 ease of use. Cons: 10 projects/month cap, 15 MW limit, no native BESS, no SLD without AutoCAD, separate proposal tool needed. Pricing: $159/month Basic, $259/month Pro, Enterprise custom.
3. OpenSolar — Best Free Alternative
Best for: Residential installers without budget for premium tooling.
OpenSolar is genuinely free for the core platform with integrated design, proposals, e-signatures, and CRM. The catch: 500 kW system cap, no US SLD without AutoCAD, photogrammetry roof modeling (less accurate than Aurora’s LiDAR), and partner-funded business model.
Pros: Free forever, integrated proposals, 28,000+ users in 185 countries, multi-currency. Cons: 500 kW cap, photogrammetry not LiDAR, partner data model, no US SLD without AutoCAD. Pricing: Free for core platform.
4. PVCase — Best for Utility-Scale Ground-Mount
Best for: Utility-scale developers needing fastest ground-mount layout.
PVCase delivers 80-90% design time reduction for ground-mount in AutoCAD-based workflows. Strong bifacial modeling (Imec/EnergyVille validated). Aurora doesn’t compete here — Aurora is residential-focused. If your pipeline includes utility-scale ground-mount, PVCase is the layout specialist; SurgePV is the integrated all-rounder.
Pros: Best-in-class utility-scale layout, bifacial validated, 4 TW designed annually. Cons: Requires AutoCAD ($2,000/yr extra), Windows-only no VMs, no SLD/financial/proposal, 6-8 week learning curve. Pricing: ~$990/year + $2,000/year AutoCAD = ~$2,990/year per seat.
5. PVsyst — Best for Lender-Required Bankability
Best for: Utility-scale developers where lenders require PVsyst output for debt.
PVsyst is the bankability gold standard for utility-scale solar yield simulation. Aurora doesn’t compete here — Aurora is design-and-proposal focused, PVsyst is yield-validation focused. For projects requiring lender-mandated PVsyst output, you’ll want PVsyst regardless of which design tool you use.
Pros: Lender default for utility-scale debt, deepest simulation methodology. Cons: Windows-only, 4-6 week learning curve, simulation-only, single-user, no design/proposal/financial workflow. Pricing: CHF 700/year (~$775).
6. Solo by EagleView — Best for Aurora-Adjacent Sales Workflow
Best for: US residential sales teams wanting fast proposals without the full design tool spend.
Solo (acquired by EagleView) focuses on the sales/proposal end of the workflow rather than deep design. Strong for installers using a separate design tool but wanting an upgrade on the customer-facing proposal experience. Less integrated than Aurora but more focused.
Pros: Strong proposal UX, EagleView roof reports integrated, sales-team friendly. Cons: Limited design depth, US-focused, requires pairing with separate design tool. Pricing: Sales-quoted.

How to Choose: Decision Framework
Step 1 — Filter by Aurora gap that matters most:
- Pricing too high? → SurgePV, HelioScope, OpenSolar
- US-centric blocking international work? → SurgePV (9 languages), OpenSolar (185 countries)
- Need carport/tracker/East-West? → SurgePV, PVCase, HelioScope Enterprise
- Need native SLD? → SurgePV (only platform with native NEC SLD without AutoCAD)
Step 2 — Filter by primary use case:
- US residential premium? → Aurora is genuinely strong; alternatives compete on price
- Commercial with storage? → SurgePV (integrated BESS) or HelioScope + Energy Toolbase stack
- International EPC? → SurgePV or OpenSolar (both have global coverage)
- Utility-scale developer? → SurgePV + (optional) PVsyst for lender output
Step 3 — Filter by team workflow:
- Mac-based engineers? Aurora works (web-based), SurgePV/HelioScope/OpenSolar all work
- Need real-time collaboration? SurgePV (built for it), Aurora (limited)
- Need transparent pricing for budget approval? SurgePV, HelioScope, OpenSolar (all publicly priced)
