TL;DR — Best Aurora Solar Alternative
SurgePV is the best Aurora Solar alternative for EPCs in 2026. It matches Aurora’s LiDAR-grade roof modeling, removes the US-centric limits, adds native NEC SLD generation without AutoCAD, and supports all major racking types including carport, single-axis tracker, dual-axis tracker, and East-West. Pricing is transparent and typically 30–50% lower than Aurora’s premium tiers. For pure C&I simulation accuracy, HelioScope (Aurora’s sister platform) is the focused choice. For free residential work, OpenSolar is the strongest no-cost option.
When You Need an Aurora Solar Alternative
Aurora’s fit profile is specific: US residential installer with budget for premium tooling, no commercial pipeline requiring automated electrical documentation, and no need for carport, tracker, or international project coverage. If your business sits outside that box, you have already felt the friction.
Here is how to map your constraint to the right alternative:
| Your Constraint | Best Alternative | Why It Works |
|---|---|---|
| Pricing too high | SurgePV, HelioScope, OpenSolar | Transparent or lower pricing; no sales-quoted premium tiers |
| Operating internationally | SurgePV (9 languages), OpenSolar (185 countries) | Native multi-currency, regional grid codes, non-US utility data |
| Commercial work needing SLDs | SurgePV | Native NEC SLD generation in 5–10 minutes; no AutoCAD required |
| Carport, tracker, or East-West projects | SurgePV, PVCase, HelioScope Enterprise | Native racking support Aurora hard-walls on standard plans |
| Need integrated CRM | Arka360 | Only major platform with built-in native CRM |
| Free option | OpenSolar | $0 licensing cost; partner-funded model |
| Lender-grade utility-scale simulation | PVsyst | Contractually required by project finance lenders |
The Hidden Cost of Aurora Solar
Aurora’s estimated $2,640–$6,000+/year per user is only the starting point. Most commercial EPCs also need AutoCAD for permit SLDs ($2,000/year), and API access requires an Enterprise tier that pushes pricing higher still. The true stack cost for a commercial designer can exceed $6,000/year — before you add a separate proposal tool or CRM. Compare total stack cost, not just headline licensing fees.
The 7 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. The functional difference is everything Aurora leaves out.
Native NEC SLD generation produces code-compliant single-line diagrams in 5–10 minutes. Wire sizing, conduit fill calculations, and voltage drop analysis run natively — no AutoCAD export, no manual drafting, no 2–3 hours of post-design CAD work per project.
Racking support covers all major types: carport, single-axis tracker, dual-axis tracker, East-West, ground-mount, and rooftop. Aurora does not support carport or tracker racking on standard plans.
International coverage spans 9 languages, 50+ countries, and regional grid codes with multi-currency proposals. Aurora’s utility rate and incentive databases are US-centric.
Pricing is transparent with published tiers. No sales call required to learn what you will pay. Most teams see 30–50% lower total cost than Aurora’s premium stack.
Pros: Comparable LiDAR roof modeling, native SLD without AutoCAD, international coverage, all racking types, transparent pricing, integrated BESS modeling, built-in proposals and financial modeling. Cons: Different CRM integration model — SurgePV uses standard API connections rather than Aurora’s Salesforce/HubSpot two-way sync. Pricing: Custom per organization with transparent published 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 over integrated sales tools.
HelioScope is Aurora’s sister platform — Aurora acquired Folsom Labs (HelioScope’s parent) in August 2021. It is browser-based with simulation accuracy within 1% of PVsyst, validated by DNV GL. For pure C&I simulation without Aurora’s residential sales overhead, HelioScope is the more focused tool at a lower price.
The limits are real. HelioScope caps users at 10 projects per month on Basic and Pro plans. It has a 15 MW system size hard limit. There is no native BESS modeling. Financial analysis scores 5.2/10 on G2. And there is no SLD generation — you still need AutoCAD for electrical documentation.
Pros: DNV GL validated accuracy, web-based, fast design iterations, 8.9/10 G2 ease of use rating. 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, especially in international markets where SLD generation is not required.
OpenSolar is genuinely free for the core platform. Integrated design, proposals, e-signatures, and basic CRM — all included at no cost. Over 28,000 users across 185 countries use it daily.
The tradeoffs matter. The 500 kW system size cap rules out commercial work. Roof modeling uses photogrammetry rather than LiDAR, which is less accurate for complex roofs. There is no US SLD generation without AutoCAD. And the partner-funded business model means project data flows toward hardware and financing partners.
Pros: Free forever, integrated proposals, 28,000+ users in 185 countries, multi-currency support. Cons: 500 kW cap, photogrammetry not LiDAR, no US SLD without AutoCAD, partner-funded data model. Pricing: Free for core platform.
4. PVCase — Best for Utility-Scale Ground-Mount
Best for: Utility-scale developers needing fastest ground-mount layout speed in AutoCAD-based workflows.
PVCase is an AutoCAD plugin, not a standalone web platform. It delivers 80–90% design time reduction for ground-mount layout through automated terrain-following rack placement. Bifacial yield modeling is validated by Imec/EnergyVille. Aurora does not compete here — Aurora is residential-focused.
If your pipeline includes utility-scale ground-mount and your team is already AutoCAD-native, PVCase removes layout friction faster than any web-based tool. SurgePV is the integrated all-rounder if you also need proposals, financial modeling, and SLD generation in the same platform.
Pros: Best-in-class utility-scale layout, bifacial validated, 4 TW designed annually across 1,800+ customers. Cons: Requires AutoCAD ($2,000/yr extra), Windows-only no VMs, no SLD/financial/proposal output, 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 contractually require PVsyst output for debt underwriting.
PVsyst is the bankability gold standard for utility-scale project finance. If your debt provider writes “PVsyst report required” into term sheets, no alternative removes that requirement.
PVsyst itself is simulation-only. No design canvas. No proposals. No SLD generation. It runs on Windows only, uses single-user licensing, and carries a 4–6 week learning curve. Teams typically pair PVsyst with a design tool (SurgePV, HelioScope, or AutoCAD-based workflows) and a separate proposal platform.
Aurora does not compete here. Aurora is design-and-proposal focused. PVsyst is yield-validation focused.
Pros: Lender default for utility-scale debt, deepest simulation methodology, no project or size caps. Cons: Windows-only, 4–6 week learning curve, simulation-only, single-user, expensive when adding required AutoCAD ($2,000/year extra). Pricing: CHF 700/year (~$775) standard.
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 and proposal end of the workflow rather than deep design. It generates proposals in minutes using address-based data input and claims utility-grade production forecasts. EagleView roof reports are integrated for per-panel shading and imaging accuracy.
This is not a design tool replacement. Solo is best for installers using a separate design platform but wanting an upgrade on the customer-facing proposal experience. It is less integrated than Aurora but more focused on the sales-specific workflow.
Pros: Strong proposal UX, EagleView roof reports integrated, sales-team friendly, on-site mobile deal creation. Cons: Limited design depth, US-focused, requires pairing with separate design tool, pricing not publicly listed. Pricing: Sales-quoted.
7. Arka360 — Best for India-First Teams With Built-In CRM
Best for: India-based residential installers wanting a native CRM, transparent pricing, and regional compliance without Aurora’s US-centric focus.
Arka360 is the only major solar platform with a built-in native CRM. It combines lead management, design, and proposal generation in one platform — eliminating the need for separate Salesforce or HubSpot subscriptions. AI-assisted panel placement and integrated permit package generation (including PE stamps) speed up residential workflows.
It does not match Aurora’s LiDAR modeling speed or proposal polish. But at $199/month with transparent self-serve pricing, it is a direct alternative for cost-sensitive teams who do not need Aurora’s US residential features.
Pros: Native CRM built in, transparent self-serve pricing, India-specific compliance and PE stamp support, AI-assisted design. Cons: Less accurate than LiDAR for complex roofs, limited global usability outside India, smaller ecosystem than Aurora. Pricing: $199/month for standard tier.

Migration Notes for Aurora Solar Users
Switching solar design platforms is not trivial, but it is also not as disruptive as most teams expect. Here is what we have learned from watching EPCs move from Aurora to SurgePV:
Project files do not transfer directly. There is no industry-standard interchange format for solar designs. However, the underlying inputs — site address, module and inverter selections, target system size, layout strategy, and financial assumptions — all transfer in 15–30 minutes per project.
Accuracy validation is fast. Rebuild 2–3 representative projects in the new platform and compare yield estimates. Aurora-to-SurgePV differences typically sit under 2% for the same inputs, which is within normal weather data and assumption variance.
The learning curve is short. Aurora users reach productivity parity on SurgePV in 5–7 working days because the underlying paradigms — LiDAR roof modeling, string design, module-level simulation — translate directly. The new skills are discovering capabilities Aurora did not have: automated SLDs, carport and tracker design, and integrated BESS modeling.
Overlap is your friend. Run both platforms in parallel for 2–4 weeks. Send new project intake to the new tool. Complete active Aurora projects in Aurora. Cancel once the pipeline is clean.
Frequently Asked Questions
What is the best Aurora Solar alternative for commercial EPCs?
SurgePV is the best Aurora Solar alternative for commercial EPCs because it adds native NEC SLD generation, carport and tracker support, and integrated BESS modeling — all without AutoCAD. Aurora requires AutoCAD for commercial electrical documentation and does not support carport or tracker racking natively.
Is there a free alternative to Aurora Solar?
OpenSolar is the best free alternative to Aurora Solar, offering integrated design, proposals, e-signatures, and CRM at no cost. However, it has a 500 kW system size cap, uses photogrammetry instead of LiDAR for roof modeling, and lacks US SLD generation without AutoCAD.
How much does Aurora Solar actually cost?
Aurora Solar pricing is not publicly listed and requires contacting sales. Industry estimates place Aurora at $2,640–$6,000+ per user per year, with premium tiers running higher. Most commercial EPCs also need AutoCAD ($2,000/year) for permit SLDs, pushing true stack cost above $4,600/year per seat.
Which Aurora Solar alternative has the best simulation accuracy?
HelioScope — owned by Aurora — delivers DNV GL-validated simulation accuracy within 1% of PVsyst, the industry gold standard. SurgePV uses equivalent module-level methodology and matches HelioScope’s accuracy. For lender-required utility-scale reports, PVsyst remains the non-negotiable standard.
Can I use HelioScope instead of Aurora Solar?
HelioScope is a partial replacement. It shares Aurora’s parent company and delivers stronger C&I simulation accuracy, but it has no integrated proposals, no CRM, no native SLD generation, and caps users at 10 projects per month. Most teams find HelioScope alone too narrow for full workflow coverage.
Why do solar companies switch from Aurora Solar?
The top reasons solar companies leave Aurora Solar are: (1) premium pricing ($2,640–$6,000+/year) that does not fit mid-market budgets; (2) US-centric data that blocks international work; (3) no native support for carport, tracker, or East-West racking; (4) no automated SLD generation without AutoCAD; and (5) API access locked behind enterprise tiers.
How long does migration from Aurora Solar take?
Most teams complete an Aurora-to-SurgePV migration in 2–4 weeks. Week 1 involves platform setup, component library import, and rebuilding 2–3 active projects for accuracy validation. Week 2 trains the design team. Weeks 3–4 run parallel workflows before cutting over fully. Aurora users typically reach productivity parity in 5–7 working days.
Does Aurora Solar work outside the United States?
Aurora Solar is primarily built for the US residential market. While it supports some international locations, its utility rate databases, incentive engines, and AHJ libraries are US-centric. For international EPCs, SurgePV (9 languages, 50+ countries) or OpenSolar (185 countries) offer stronger global coverage.
Bottom Line
Aurora Solar is a capable platform with genuine market leadership — 20 million projects, 7,000+ companies, and industry-leading LiDAR + AI roof modeling. For US residential installers with budget for premium tooling and no need for commercial electrical documentation or non-standard racking, Aurora delivers strong ROI.
But its architecture assumes a specific profile: US residential, premium budget, separate CAD team for permit SLDs, and no carport, tracker, or international pipeline. If your business has outgrown that profile, the right alternative depends on which constraint is biting hardest:
- Premium pricing or lack of transparency? → SurgePV, HelioScope, OpenSolar, or Arka360.
- US-centric blocking international work? → SurgePV or OpenSolar.
- Need carport, tracker, or East-West racking? → SurgePV or PVCase.
- Need automated SLDs without AutoCAD? → Only SurgePV offers this natively.
- Free option for pure residential? → OpenSolar.
- Lender requiring PVsyst for utility-scale? → PVsyst is non-negotiable.
Your next steps:
- Audit your current stack cost — include Aurora plus every required add-on (AutoCAD, CRM, proposal tool, API access).
- Map your 12-month project pipeline — count how many projects include commercial work, battery storage, carport, tracker, or non-US locations.
- Book a 20-minute SurgePV demo using one of your actual project types to compare workflow speed and total cost directly against your current Aurora stack.
