Expert Verified — Written by Keyur Rakholiya, SurgePV Editorial. 10 tools tested as replacements for the SunPower dealer design workflow. Pricing verified July 2026. Based on 1+ GW of delivered projects and thousands of designs reviewed across 50+ countries.
SunPower Corporation filed for Chapter 11 bankruptcy on August 5, 2024. Complete Solaria bought its Blue Raven, New Homes, and dealer network assets for $45 million, a deal approved by the Delaware bankruptcy court on September 23, 2024. The SunPower brand lives on under new ownership. The old dealer toolchain did not.
That left thousands of former SunPower dealers without a home for design work. The SunPower design tool was never vendor-neutral anyway. It was built to sell Maxeon panels and SunVault storage, inside a closed dealer network.
We tested 10 alternatives that fix both problems. Every tool here is vendor-agnostic or openly free. We ranked them for the audience that lost the most in the collapse: US residential and light commercial installers rebuilding their design workflow from scratch.

1. Aurora Solar — Best Overall Alternative for Former SunPower Dealers
Aurora Solar is where most enterprise SunPower dealers landed. Over 7,000 companies use it, and its workflow maps closely to what the old dealer portal offered.
What It Does Well
The component database is the first thing ex-SunPower dealers need. Aurora covers thousands of modules and inverters from all major brands, including Maxeon. You quote the hardware that wins the deal, not the hardware a manufacturer wants sold.
Sales Mode turns a finished design into a proposal in under 3 minutes. LIDAR-assisted 3D modeling and automated shading analysis feed real numbers into every quote. Contract Manager adds e-signatures in the same flow.
G2 reviewers rate Aurora 4.6 out of 5, with 24/7 support scoring 9.0 out of 10. For a dealer team of 5 to 50 reps, the permissions and admin controls justify the enterprise price.
Our Take: Aurora is the closest functional replacement for the SunPower dealer experience, minus the hardware lock-in. You pay enterprise pricing for it, and the automated roof modeling still misses obstructions often enough that reps must verify every design.
Where It Falls Short
Aurora does not publish pricing, and reviewers consistently call it expensive for small teams. Roof auto-detection is hit-or-miss on unusual roofs and in areas with weak imagery. Complex industrial projects stretch it beyond its comfort zone.
Key Features
- LIDAR-assisted 3D roof modeling with automated shading
- Sales Mode proposals in under 3 minutes
- Broad module and inverter database including Maxeon
- Contract Manager with e-signature
Pricing
- Foundation, Build, Grow, Scale: Custom pricing, contact sales
- Free trial: Guided demo only
Who Should Use Aurora Solar
Strong fit: US residential sales teams of 5+ reps rebuilding after the SunPower collapse. Probably not right for: Solo installers, tight budgets, and non-US markets.
2. SurgePV — Best Alternative for Design-to-Proposal Speed
Full disclosure: we build SurgePV. We ranked it #2 because Aurora still wins for large US sales orgs. For dealers who want quotes backed by real engineering, this is where we are strongest.
What It Does Well
The old SunPower tool bundled design and sales for a reason. Splitting them creates errors. A rep copies a production number from 1 tool into another, the shading assumption gets lost, and the savings promise drifts from reality.
SurgePV removes the handoff. You design the system in 3D, run physics-based shadow analysis, and pull generation and financial figures in 1 platform. The proposal inherits the same numbers the simulation produced.
The generation and financial tool models cash, loan, lease, and power purchase agreement (PPA) scenarios with payback, internal rate of return (IRR), and net present value (NPV). Clara AI helps teams move faster on routine proposal writing. In our testing, a residential design takes under 10 minutes from address to sendable proposal.
Our Take: If your post-SunPower stack became a patchwork of 3 tools, SurgePV collapses it back to 1. It is vendor-neutral, cloud-only, and priced for small teams rather than enterprise orgs.
Where It Falls Short
SurgePV has no native CRM, so pipeline tracking needs an external tool. The component database is deepest in markets we serve directly. Very large sales orgs may still prefer Aurora’s rep management layer.
Key Features
- 3D rooftop design with automated string sizing
- Physics-based shadow analysis for accurate production estimates
- Branded solar proposals built from live design data
- Module and inverter database across major brands
Pricing
- For 3 Users plan: $1,899/year — design, simulation, financials, and proposals included
- Free trial: Available with full design and proposal capabilities
Who Should Use SurgePV
Strong fit: Installers and EPCs who want 1 vendor-neutral platform from design to signed proposal. Probably not right for: Teams wanting a free tool, or sales-only orgs needing built-in CRM.

3. OpenSolar — Best Free SunPower Design Tool Alternative
OpenSolar is the only genuinely free platform on this list. Over 28,000 users in 185+ countries pay nothing for design, CRM, proposals, and e-signatures.
What It Does Well
The price is the headline: $0 forever, unlimited projects, unlimited users. OpenSolar monetizes hardware partners and lenders instead of installers. For a dealer who just lost their software stack and their financing partner in the same bankruptcy, that combination matters.
Speed is real. Users report proposals in under 2 minutes once templates are set. The interactive proposals are mobile-friendly and include cash, loan, lease, and PPA options with lender integrations in the US, UK, and Australia.
The component database is broad and includes Maxeon modules. Accuracy is third-party validated by PV Evolution Labs (PVEL) and a US government agency. Most teams are operational in under 1 day.
Our Take: For a 1 to 10 person shop rebuilding on a budget, OpenSolar is the obvious first stop. Know the ceiling: it tops out around 500 kW and lacks deep engineering controls.
Where It Falls Short
The 500 kW cap rules out larger commercial work. Photogrammetry-based modeling is less precise than LIDAR. There is no offline mode, and the CRM cannot match dedicated platforms for big teams.
Key Features
- 3D design studio with real-time shading
- Interactive proposals with e-signature
- Built-in CRM, payments, and financing integrations
- Full iOS and Android apps
Pricing
- Free tier: $0 — unlimited projects, users, and features
- Free trial: Not needed; the product is free
Who Should Use OpenSolar
Strong fit: Small residential installers and budget-conscious dealers restarting after SunPower. Probably not right for: Projects above 500 kW, bank-grade engineering, offline field work.
4. Solargraf — Best Alternative for Battery-Focused Residential Designs
Many SunPower dealers built their pitch around SunVault storage. Solargraf, owned by Enphase since 2021, is the strongest replacement for storage-led residential sales.
What It Does Well
Battery modeling is the core strength. Solargraf supports Enphase IQ Battery, Tesla Powerwall, and 25+ manufacturers with backup scenario comparisons. That covers nearly every SunVault replacement conversation a dealer will have.
California installers get NEM 3.0 optimization with California Public Utilities Commission (CPUC) hourly sell rates. The Good/Better/Best feature presents 3 pricing options in 1 proposal. The Express Editor lets reps adjust quotes on the spot.
Permitting is included. DIY permit packages generate authority having jurisdiction (AHJ) compliant documents with validated single-line diagrams. For residential shops, that covers design through permit in 1 subscription.
Our Take: Solargraf is the natural pick for dealers whose book of business is storage-heavy residential. Cross-check its shading output against a second tool before you trust the production numbers.
Where It Falls Short
Shading accuracy is the most common user complaint, and some teams verify production estimates in Aurora or HelioScope. There is no built-in CRM. Billing is annual only, and it costs more than OpenSolar’s free tier.
Key Features
- Battery design for 25+ manufacturers
- NEM 3.0 optimization with hourly export rates
- Good/Better/Best multi-option pricing
- DIY AHJ-compliant permit packages
Pricing
- Starter: $2,799/year — 240 projects, 2 users
- Free trial: Available; new users get 120 project credits
Who Should Use Solargraf
Strong fit: US residential dealers with storage-heavy pipelines, especially in California. Probably not right for: Teams needing shading precision guarantees or a built-in CRM.
5. HelioScope — Best Alternative for C&I Projects
SunPower’s commercial dealers need a different class of tool. HelioScope, now part of Aurora Solar, pairs bankable simulations with fast design for commercial and industrial (C&I) work.
What It Does Well
Accuracy is validated. HelioScope was found by DNV to be within 1% of PVsyst, and Sunstone Credit recognized it as bankable in October 2025. Users report 4x faster design iterations than desktop tools.
The module-level simulation handles rooftops, carports, and ground mounts up to 15 MW. P50 comes on the Basic plan; P90, P95, and P99 arrive on Pro. The financial calculator covers NPV, IRR, payback, and levelized cost of energy (LCOE).
The Pro plan adds a proposal editor with custom branding and 1-click sharing. For 100 kW to 5 MW C&I deals where the buyer wants credible yield numbers, the combination works well.
Our Take: HelioScope is the right migration target for dealers who did SunPower commercial work. Budget for Energy Toolbase alongside it if storage economics decide your deals.
Where It Falls Short
There is no native battery modeling, so storage quotes need an integration. Financial analysis scores 5.2 out of 10 on G2. Residential work under 15 kW feels clumsy, and performance lags past 10,000 modules.
Key Features
- Module-level simulation within 1% of PVsyst
- P50/P90/P95/P99 production estimates
- Drag-and-drop proposal editor with branding
- Energy Toolbase and PVsyst export integrations
Pricing
- Basic: $159/month — 1 user, 10 projects, 1.25 MW cap
- Pro: $259/month — adds LIDAR, P90+, financials, proposals
- Free trial: Demo only; academic discounts available
Who Should Use HelioScope
Strong fit: C&I installers and EPCs designing 100 kW to 5 MW projects. Probably not right for: Residential-focused teams, heavy storage deals, off-grid systems.

6. PVsyst — Best Alternative for Engineering-Grade Yield Estimates
PVsyst is not a sales tool. It earns its place because financed projects still quote from its numbers. Lenders have trusted its reports for 30+ years.
What It Does Well
PVsyst is the bankability standard. P50, P90, P95, and P99 uncertainty analysis is built in, and most financiers require exactly that. Billions of dollars in solar projects have closed on PVsyst reports.
The technical depth is unmatched. Version 8 adds unlimited orientations, sub-hourly clipping correction, and detailed loss modeling for soiling, degradation, and mismatch. The component database holds 14,000+ modules and 4,500+ inverters, including Maxeon lines.
G2 reviewers rate its design and engineering at 9.4 out of 10, the highest in the category. For a C&I quote where credibility decides the deal, a PVsyst-backed yield figure carries weight no polished proposal matches.
Our Take: Use PVsyst to generate the numbers, then pair it with a real proposal tool to present them. It wins deals that require lender-grade proof and loses on everything customer-facing.
Where It Falls Short
The interface is dated, and ease of use scores 7.1 out of 10 on G2. It runs on Windows only, with no cloud collaboration. There are no customer-facing proposals at all, and the learning curve is steep.
Key Features
- P50/P90/P95/P99 bankable uncertainty analysis
- 14,000+ modules and 4,500+ inverters in the database
- Detailed loss, bifacial, and storage modeling
- Batch processing and command-line automation
Pricing
- Professional: CHF 700/year (~$775) — volume discounts from 2 licenses
- Free trial: 30 days, full features
Who Should Use PVsyst
Strong fit: Engineers and EPCs quoting financed C&I or utility-scale projects. Probably not right for: Residential sales teams and anyone needing polished proposals.
7. Energy Toolbase — Best Alternative for Storage Economics
Energy Toolbase (ETB) is the economics engine behind many C&I solar and storage quotes. For dealers replacing SunVault deals, its utility rate database is the deepest we have tested.
What It Does Well
The numbers are the product. ETB maintains 70,000+ utility rates across 1,200+ territories with an in-house rates team. Savings quotes built on stale tariffs die in diligence; ETB’s do not.
Storage economics are where it separates from the pack. Multi-value stream analysis stacks demand charge reduction, time-of-use arbitrage, and grid services in 1 model. NEM 1.0, 2.0, and 3.0 modeling covers California’s complexity.
Customer evidence is strong. SunGreen Systems cut proposal time from 16 hours to 1 to 2 hours using ETB. Proposals generate as professional web URLs with unlimited optimizations.
Our Take: If your storage quote’s credibility rests on savings math, ETB is the most defensible tool available. Pair it with a design tool, because it has none.
Where It Falls Short
There is no native design capability; you import 8,760-hour production data from HelioScope, Aurora, or PVsyst. There is no CRM integration, no mobile app, and pricing starts at $199 per user per month. Public reviews are scarce.
Key Features
- 70,000+ utility rates maintained in-house
- Solar plus storage NPV, IRR, payback, and cash flow
- NEM 3.0 and multi-value stream modeling
- Instant PPA quotes via financing partners
Pricing
- ETB Developer: $199/user/month — 10% annual discount
- Free trial: Demo only
Who Should Use Energy Toolbase
Strong fit: C&I developers and storage-heavy dealers whose savings math must survive scrutiny. Probably not right for: Residential installers wanting an all-in-one, or tight budgets.
8. Scanifly — Best Alternative for Survey-Accurate 3D Models
SunPower dealers sold premium systems on difficult roofs. Scanifly replaces guesswork with drone and mobile photogrammetry, so the design matches the real site.
What It Does Well
Accuracy is the pitch. Scanifly builds 3D models from drone imagery or a phone-based survey, capturing obstructions, roof geometry, and shading objects that satellite tools miss. Designs exported from Scanifly flow into Aurora, OpenSolar, and other platforms.
The workflow suits premium residential. A field rep surveys the site, the office designs on the true 3D model, and the production estimate reflects actual shade. That closes the gap between quoted and delivered output.
For dealers burned by over-promised production figures, that precision protects margins and reputation. It also cuts truck rolls for change orders caused by bad satellite measurements.
Our Take: Scanifly is the best answer when site accuracy decides the deal. It is a survey and modeling layer, not a full sales platform, so budget for a proposal tool alongside it.
Where It Falls Short
Scanifly is not an all-in-one. Proposal depth, financing options, and CRM are limited compared with Aurora or OpenSolar. Drone workflows add field time, and pricing scales with survey volume.
Key Features
- Drone and mobile photogrammetry 3D modeling
- Automatic obstruction and shading capture
- Exports to Aurora, OpenSolar, and other design platforms
- CAD-compatible outputs for engineering teams
Pricing
- Plans: From roughly $99/month, scaling with survey volume — contact sales
- Free trial: Available
Who Should Use Scanifly
Strong fit: Premium residential installers who survey complex roofs and need exact models. Probably not right for: Teams wanting 1 tool for design, proposals, and CRM.
9. Arka360 — Best Alternative for SMB All-in-One Workflows
Arka360 serves 4,000+ installers across 27 countries. It bundles design, CRM, and proposals at prices a small dealer can absorb during a rebuild.
What It Does Well
The all-in-one scope stands out at this price. Design, LIDAR-based shading analysis, a built-in CRM, and proposal generation live in 1 platform. Users report proposals in under 5 minutes and full workflows in 20.
Ease of use is the top praise in G2 reviews, and the platform holds a 4.7 out of 5 rating across 117 reviews. Support earns strong marks, which matters when a whole team is learning a new stack at once.
For EPCs, permit packages are the differentiator. Arka360 delivers NEC-compliant permit sets in 48 hours, or under 8 hours expedited, with professional engineer (PE) stamps available.
Our Take: Arka360 is the practical choice for a growing dealer that needs CRM plus design without enterprise pricing. Expect rough edges in performance and repetitive layout steps.
Where It Falls Short
Missing features are the top user complaint on G2. Users report performance issues and occasional instability. Panel re-selection for each new polygon slows layout work, and utility-scale support is limited.
Key Features
- 3D design with LIDAR-based shading analysis
- Built-in CRM with lead and pipeline tracking
- NEC-compliant permit packages with PE stamps
- ArkaGo mobile app for field proposals
Pricing
- US Basic: $199/month — 1 user, residential and commercial
- US Premium: $358/month — 2 users, battery sizing, CAD export
- Free trial: Contact sales
Who Should Use Arka360
Strong fit: Small and mid-size installers wanting design, CRM, and permits in 1 subscription. Probably not right for: Utility-scale developers and teams needing polished performance at scale.
10. Pylon — Best Pay-Per-Project Alternative
Pylon (GetPylon) is an Australian-built tool with pay-per-project pricing. Over 3,500 solar businesses use it, and a 2025 installer survey voted it the top solar design tool.
What It Does Well
The pricing model fits a dealer in transition. At $4 per project with no monthly fees, you pay only when you quote. Unlimited team users come with no per-seat costs.
Speed is excellent. Users report proposals in under 2 minutes, and panel placement takes under a minute after familiarization. The 3D shading analysis won a Finder innovation award in 2021.
The documentation set is unusually complete for the price. One-click single-line diagrams, voltage rise reports, job sheets, and owner manuals generate automatically. The iPad-optimized interface suits on-site sales.
Our Take: Pylon is the best economic fit for dealers quoting under 20 projects a month while they rebuild volume. Template variety is the trade-off.
Where It Falls Short
Only 3 proposal templates limit brand customization. Design variations cap at 5 per project. Utility-scale and advanced C&I work is out of scope, and imagery coverage has gaps in 10 to 20% of regions.
Key Features
- Pay-per-project pricing with unlimited users
- Award-winning 3D shading analysis
- One-click single-line diagrams and voltage rise reports
- iPad-optimized for on-site quoting
Pricing
- Standard: $4/project — design, imagery, financials, proposals
- Pro: $10/project — adds batteries, custom loads, commercial
- Free trial: 5 free Standard projects, no credit card
Who Should Use Pylon
Strong fit: Small residential dealers with variable quote volume. Probably not right for: High-volume teams, C&I projects, and brands needing custom templates.
Decision Flowchart: Which Alternative Fits Your Situation
Match your post-SunPower reality to a shortlist before you book demos.
- US residential sales team of 5+ reps: Aurora Solar. Closest match to the old dealer workflow, without the hardware lock-in.
- Installer wanting engineering-backed quotes: SurgePV. Design, shading, financials, and proposal stay in 1 workflow.
- Solo installer or tight budget: OpenSolar. Free forever with CRM and e-signatures.
- Storage-heavy residential pipeline: Solargraf, with Energy Toolbase when savings math decides the deal.
- Commercial dealer, 100 kW to 5 MW: HelioScope, plus PVsyst when lenders need bankable reports.
- Premium installs on complex roofs: Scanifly for the survey model, paired with a proposal tool.
- Small team needing CRM plus permits: Arka360.
- Rebuilding volume slowly: Pylon. Pay per project until monthly spend makes sense.
How to Choose a SunPower Design Tool Alternative
Evaluate any replacement against these 6 dimensions before you commit.
- Vendor neutrality first. The SunPower collapse showed the risk of a manufacturer-owned tool. Pick software with a broad component database so no single brand can strand you again.
- Design accuracy. Check how shading is modeled. Physics-based solar shadow analysis software beats rough satellite estimates on obstructed roofs.
- Storage support. If your book is SunVault-heavy, verify battery modeling depth and export rate handling for your utility territories.
- Proposal output. Interactive web proposals with e-signature close faster than emailed PDFs. Check template customization limits before you migrate.
- Rebuild cost. Divide annual subscription by your quote volume. Free and per-project tools win at low volume; flat subscriptions win at high volume.
- Data continuity. No tool imports old SunPower designs. Budget 10 to 30 minutes per active project to rebuild, and prioritize deals closest to signature.
Pro Tip
Rebuild your 5 most recent lost deals in each trial tool. The platform that quotes your actual work fastest and most accurately is the one worth paying for, not the one with the longest feature list.
The Bigger Lesson: Never Let a Manufacturer Own Your Workflow
Here is the contrarian part. The SunPower design tool was never really free. Dealers paid for it with hardware exclusivity, and when the company failed, the tool, the financing, and the warranty chain all broke at once.
Single-vendor stacks always carry that risk. A manufacturer-owned design tool exists to sell that manufacturer’s equipment. When the manufacturer stumbles, your sales process stumbles with it.
Vendor-neutral solar design software costs money up front and saves you during the exact moments that kill solar businesses. Every tool on this list keeps your design data, your customer pipeline, and your hardware choices independent. That independence is the real feature worth buying.
Conclusion
The SunPower bankruptcy stranded thousands of dealers, but the replacement market is strong. Aurora Solar is the closest overall match for enterprise dealer teams. SurgePV fits installers who want engineering-backed proposals in 1 workflow. OpenSolar gets a small shop running again for $0.
Your next 3 moves:
- Shortlist 2 or 3 tools from the decision flowchart that match your segment and volume.
- Rebuild 5 real deals in each free trial and compare speed, shading accuracy, and proposal quality.
- Verify vendor neutrality by checking that your preferred module, inverter, and battery brands all appear in the component database.

Frequently Asked Questions
What happened to the SunPower Design Studio tool?
SunPower Corporation filed for Chapter 11 bankruptcy in August 2024. Complete Solaria acquired its Blue Raven, New Homes, and dealer network assets for $45 million in September 2024 and relaunched under the SunPower brand. The original dealer design toolchain tied to the old SunPower Corporation was discontinued or rebuilt, so former dealers moved to vendor-neutral design software.
What is the best free alternative to the SunPower design tool?
OpenSolar is the strongest free option. It offers 3D design, shading analysis, proposals, and e-signatures at no cost for systems up to about 500 kW. SolarEdge Designer is also free but locked to SolarEdge hardware.
Which alternative is best for battery and storage designs?
Solargraf models 25+ battery brands including Tesla Powerwall and Enphase IQ Battery. Energy Toolbase is the strongest option for storage economics like demand charge reduction and time-of-use arbitrage.
Do I need a tool that supports Maxeon panels?
Yes, if you still quote Maxeon modules. Vendor-neutral tools like Aurora Solar, OpenSolar, PVsyst, and SurgePV maintain large component databases that include Maxeon and most competing brands, so you are never locked to 1 manufacturer again.
How much do SunPower design tool alternatives cost?
Prices range from free (OpenSolar, SolarEdge Designer) to $4 per project (Pylon) to $159–$259 per month (HelioScope) to custom enterprise pricing (Aurora Solar). SurgePV costs $1,899 per year for 3 users with design, simulation, financials, and proposals included.
Can I migrate old SunPower designs into a new tool?
Not directly. There is no export path from the discontinued SunPower toolchain into third-party software. Most dealers rebuild active designs from scratch, which takes 10 to 30 minutes per residential project in a modern cloud tool.
