RatedPower is one of the strongest cloud platforms for utility-scale PV and BESS design. It serves 4,300+ professionals across 130+ countries. But it does not fit every team.
The platform skips residential and small C&I entirely. Pricing is quote-based, with no free trial. Teams selling rooftop projects often pay for engineering depth they never use.
We tested 10 RatedPower alternatives on real projects over 6 weeks. Our team includes EPC engineers who have delivered 1+ GW across 50+ countries. This guide ranks each tool by utility-scale capability, cloud access, pricing, and ease of use.

The 10 Best RatedPower Alternatives
1. SurgePV — Best All-in-One Tool for Residential and C&I Design + Proposals
SurgePV is a cloud platform for rooftop design, shading analysis, simulation, and proposals. It covers the segment RatedPower leaves out: residential and C&I up to roughly 5 MW.
What It Does Well
Most teams leaving RatedPower hit the same problem. They pay utility-scale prices for rooftop work. They also lose time exporting designs into separate proposal tools.
That gap costs real money. A C&I team running 30 proposals a month can lose 2–3 hours per project on tool switching. Over a year, that is a full-time salary.
SurgePV closes the gap in one browser session. You model the roof with AI-assisted detection, run per-panel shading, and generate a branded proposal. No AutoCAD license and no exports between 3 tools.
The proposal engine produces client-ready PDFs with system diagrams, financials, and financing options. Sales teams white-label outputs for dealer networks. Design-to-proposal time typically drops under 1 hour per project.
Our Take: SurgePV is the practical RatedPower alternative for teams whose pipeline is rooftops, not 100 MW plants. We would not use it — or any rooftop tool — for lender-grade utility-scale engineering.
Where It Falls Short
SurgePV is not a utility-scale platform. It lacks bankable P50/P90 reporting for project finance, substation engineering, and terrain-following tracker design. Teams developing plants above 5 MW should choose PVcase, RatedPower, or PVsyst instead.
Key Features
- AI-assisted 3D roof modeling with per-panel shading analysis
- Automated NEC-compliant SLD generation without AutoCAD
- Integrated financial modeling and branded proposal engine
- Support for carport, tracker, and East-West racking layouts
Pricing
- Individual: $1,899/user/year — all features included, no per-project fees
- Team (3 users): $1,499/user/year — free onboarding included
- Team (5+ users): $1,299/user/year — volume pricing
- Free trial: Full access to all features, no credit card required
Who Should Use SurgePV
Strong fit: Residential installers, C&I EPCs, and sales-led teams needing design, simulation, and proposals in one platform.
Probably not right for: Utility-scale developers, IPPs, and banks needing bankable yield reports for project finance.
2. PVcase — Best AutoCAD-Based Tool for Utility-Scale Design
PVcase is the closest direct RatedPower alternative for utility-scale engineering. The Vilnius-based company serves 1,800+ customers designing 4 TW of projects annually.
What It Does Well
PVcase runs inside AutoCAD, which many engineering teams already own. Ground Mount automates layout, stringing, grading, and voltage drop calculations. Users report 80–90% design time savings versus manual CAD work.
The product suite covers the full development cycle. Prospect handles cloud-based site selection in minutes. Yield adds ray-tracing energy modeling with validated bifacial accuracy. Data flows between products without re-entry.
BESS support is a genuine strength. PVcase handles AC-coupled, DC-coupled, and standalone storage natively. Export to PVsyst works through standard .DAE and .PVC formats.
Our Take: If your engineers think in DWG files, PVcase beats RatedPower on engineering detail. If they do not touch AutoCAD, the learning curve will cost you 4–8 weeks per hire.
Where It Falls Short
Ground Mount and Roof Mount require a Windows machine with AutoCAD 2019 or newer. Prospect and Yield run in the cloud, but the core design tools do not. There is no VM support, no built-in financial modeling, and no component database. You input module specs manually, and cable loss calculations require manual work.
Key Features
- End-to-end suite: Prospect, Ground Mount, Roof Mount, and Yield
- Terrain-following tracker placement with cut/fill grading analysis
- Native AC/DC-coupled and standalone BESS design
- PVsyst export and validated bifacial yield modeling
Pricing
- Ground Mount: Custom quotes only — reported around $12,999/year per module
- AutoCAD required: Add $1,800–$2,000 per seat annually
- Free trial: 2-week trial available; free licenses for students and educators
Who Should Use PVcase
Strong fit: Utility-scale EPCs and developers with existing AutoCAD workflows and dedicated engineering staff.
Probably not right for: Residential installers, Mac-based teams, and small businesses sensitive to 5-figure annual costs.
3. Aurora Solar — Best Enterprise Tool for Residential + C&I
Aurora Solar is the most adopted design platform in US residential solar. Over 7,000 companies have created 20 million+ designs on it.
What It Does Well
Aurora’s strength is the sales workflow. Sales Mode produces proposals in under 3 minutes. Lead Capture, Contract Manager, and e-signature integration cover the full sales cycle.
The design engine uses LiDAR-assisted 3D modeling with automated shading analysis. G2 users rate its 3D visualization at 9.5/10 and energy estimates at 9.2/10. Support runs 24/7.
The HelioScope acquisition added credible C&I capability. Enterprise tiers include an Expert Design Service where Aurora’s team builds your 3D models.
The efficiency gains are real for high-volume sales teams. Users report cutting in-home sales time from 2 hours to 20 minutes. Lead Capture AI customers report up to 4x web lead volume.
Our Take: Aurora is the safe enterprise pick for US residential sales organizations. International teams and cost-sensitive mid-market EPCs will feel the premium pricing and US-centric data fast.
Where It Falls Short
Pricing is not public and industry estimates run $2,640–$6,000+ per user per year. Commercial electrical documentation still leans on AutoCAD. Native support for carport, tracker, and East-West racking is missing on standard plans.
Key Features
- LiDAR-assisted 3D modeling with automated shade analysis
- Sales Mode proposals in under 3 minutes with e-signature
- Battery and storage modeling for whole-home proposals
- Sync API and pricing API on Build tier and above
Pricing
- Foundation/Build/Grow/Scale: Custom quotes only — contact sales
- Estimated range: $2,640–$6,000+ per user per year (industry estimates)
- Free trial: Demo and product tour only; no self-serve trial
Who Should Use Aurora Solar
Strong fit: US residential installers and enterprise sales teams with budget for premium tooling.
Probably not right for: International EPCs, utility-scale developers, and teams needing transparent pricing.
4. HelioScope — Best Tool for C&I Design Without AutoCAD
HelioScope, owned by Aurora Solar, is a browser-based C&I design platform. It has been used to design 1,200 GW of projects across 100+ countries.
What It Does Well
HelioScope runs module-level simulation in the browser. No installation, no AutoCAD, no IT involvement. Users rate ease of use at 8.9/10 — the highest in this list.
Accuracy is independently validated. DNV GL found results within 1% of PVsyst. In October 2025, Sunstone Credit recognized HelioScope as bankable — a first for a web-based platform.
Speed is the other selling point. Users report running 4x more layout iterations than with desktop tools. The component database covers 40,000+ modules and 10,000+ inverters. Weather data options include TMY2/3, Meteonorm, and NREL NSRDB.
Our Take: For C&I projects from 100 kW to 5 MW, HelioScope is the fastest path to a defensible yield estimate. Just plan a second tool for proposals and battery modeling.
Where It Falls Short
There is no native BESS modeling — you export to Energy Toolbase or Homer. The 15 MW hard cap rules out true utility-scale work. Financial analysis scores just 5.2/10 on G2, and proposals require the Pro tier.
Key Features
- Module-level simulation validated within 1% of PVsyst
- Browser-based 3D design with hourly shade mapping
- P50/P90/P95/P99 production estimates on Pro and Enterprise
- PVsyst export and API access on Enterprise tier
Pricing
- Basic: $159/month or $1,620/year — 1 user, 10 projects/month, 1.25 MW cap
- Pro: $259/month or $2,640/year — LiDAR, financials, proposals, 5 MW cap
- Free trial: Demo only; academic and nonprofit discounts available
Who Should Use HelioScope
Strong fit: C&I installers and developers designing 100 kW–5 MW projects who want PVsyst-grade accuracy without desktop software.
Probably not right for: Residential-only shops, battery-heavy projects, and anything above 15 MW.
5. PVsyst — Best Tool for Bankable Yield Simulation
PVsyst is the 34-year-old simulation standard from Geneva. Billions of dollars in solar projects have been financed on PVsyst reports.
What It Does Well
Lenders ask for PVsyst by name. Its P50/P90 uncertainty analysis is the reference for independent engineering reviews. No cloud platform has displaced it for project finance.
Depth is unmatched for the price. The database holds 14,000+ modules and 4,500+ inverters. Bifacial modeling, trackers, off-grid systems, and detailed loss trees are all included.
Version 8 added unlimited orientations and sub-hourly clipping correction. G2 users rate design and engineering at 9.4/10 and financial analysis at 8.9/10.
Our Take: Every serious utility-scale stack ends with a PVsyst run. At ~$775/year, it is the cheapest credibility you can buy. Pair it with a faster layout tool, and accept the dated interface.
Where It Falls Short
PVsyst is Windows-only desktop software with no cloud collaboration. There are no SLDs, no wire sizing, and no permit documentation. Ease of use scores 7.1/10 — the learning curve is steep, and the interface feels its age.
Key Features
- Bankable P50/P90/P95/P99 yield reports accepted by lenders worldwide
- Detailed loss modeling: soiling, LID, mismatch, aging, and temperature
- Bifacial, single-axis, and dual-axis tracker simulation
- PVsystCLI for batch automation via Python, R, or Excel
Pricing
- Professional: CHF 700/year (~$775) — full features, volume discounts from 2 licenses
- PVsystCLI: CHF 3,000/year — command-line automation
- Free trial: 30 days, full features, no restrictions
Who Should Use PVsyst
Strong fit: Solar engineers, EPCs, and developers who need lender-accepted simulation for financed projects.
Probably not right for: Sales teams, Mac shops, and anyone needing layouts, SLDs, or proposals.

6. OpenSolar — Best Free RatedPower Alternative
OpenSolar is a fully free design and sales platform used by 28,000+ professionals in 185+ countries. Partners such as distributors and lenders fund it — installers pay nothing.
What It Does Well
Free means free. Unlimited projects, unlimited users, and all features at $0. Design, CRM, proposals, e-signatures, and payments ship in one system.
Speed is the other draw. Users generate proposals in under 2 minutes. Most teams are operational within 1 day of signup.
The platform covers 185+ countries with multiple currencies. Full iOS and Android apps handle design, sales, and e-signature in the field.
The Ada assistant adds voice-activated design and lead generation. Financing integrations cover Sunlight Financial, EnFin, Brighte, and Propensio. QuickBooks Online and Xero connections are in beta.
Our Take: OpenSolar is the easiest recommendation in this list for budget-constrained residential teams. Treat the 500 kW cap and photogrammetry accuracy as hard limits, not asterisks.
Where It Falls Short
OpenSolar uses photogrammetry, not LiDAR, so roof models are less precise. The 3D designer caps at 500 kW, and the platform is web-only with no offline mode. Engineering depth stops well short of NEC-grade electrical documentation. Large enterprises will also outgrow the built-in CRM quickly.
Key Features
- 3D design studio with real-time shading analysis
- Interactive proposals with e-signature and financing integrations
- Built-in CRM, payments, and full mobile apps
- Free forever with unlimited projects and users
Pricing
- Full platform: $0 — free forever, all features included
- Optional extras: HD premium imagery bundles; enterprise white-label at custom pricing
- Free trial: Not needed — the platform itself is free
Who Should Use OpenSolar
Strong fit: Small residential installers and startups needing a zero-cost, all-in-one platform.
Probably not right for: C&I projects above 500 kW, bank-grade engineering, and offline fieldwork.
7. Solargraf — Best Tool for Simple Residential Design
Solargraf is an Enphase-owned design and proposal platform. It targets residential installers who value speed over engineering depth.
What It Does Well
Proposal generation takes about 3 minutes. The Express Editor lets reps adjust pricing on the spot without looping in a design team. Good/Better/Best options give homeowners choices in one document.
Permitting is built in. The platform generates AHJ-compliant permit packages and permit-ready SLDs with validations. California installers get native NEM 3.0 modeling with CPUC 8760-hour sell rates.
Battery support covers Enphase IQ, Tesla Powerwall, and 25+ manufacturers. Enphase ownership means production data validates against Enlighten.
NREL and NYSERDA have verified the shading methodology. A third-party bankability report validates production accuracy. Even so, field reports of shading misses are frequent enough to warrant caution on tree-heavy sites.
Our Take: Solargraf wins on proposal speed and Enphase ecosystem fit. Verify its shading output against a second tool before you promise production numbers to a customer.
Where It Falls Short
Shading accuracy is the most common user complaint — some teams double-check estimates in Aurora or HelioScope. There is no native CRM, no QuickBooks integration, and no offline mode. Pricing runs high against a free competitor like OpenSolar. Support wait times have increased as the user base grows.
Key Features
- 3-minute proposals with Good/Better/Best pricing options
- DIY AHJ-compliant permit packages and SLDs
- NEM 3.0 optimization for California installers
- Battery design across 25+ manufacturers
Pricing
- Starter: $2,799/year — 240 projects, 2 users
- Small Business: $4,799/year — 480 projects, 4 users
- Free trial: Available; extra projects cost $9–11 each
Who Should Use Solargraf
Strong fit: Residential installers in the Enphase ecosystem, California NEM 3.0 work, and mobile sales teams.
Probably not right for: Budget-first startups, utility-scale developers, and teams needing precise shading on complex roofs.
8. Arka360 — Best Tool for Emerging-Market EPCs
Arka360 combines design, proposals, and a native CRM for 4,000+ installers across 27 countries. Its India pricing makes it the value pick for emerging-market EPCs.
What It Does Well
The built-in CRM is the differentiator. Lead tracking, opportunity management, and business analytics sit in the same platform as design. No other tool in this list bundles CRM natively at this price.
Design capabilities cover LiDAR-precision modeling, shading analysis, and automated stringing. Proposals generate in under 5 minutes with 3D simulations and financing models.
Permit services are a genuine time-saver. Arka360 delivers NEC-compliant permit packages in 48 hours, with PE stamps for structural and electrical. Users report permit approvals within the hour in some jurisdictions.
Review sentiment is strong for a mid-market tool. Ease of use is the top praise, with 4.7/5 across 117 G2 reviews. Support quality also earns consistent mentions.
Our Take: For Indian and emerging-market EPCs, the ₹46,000/year Lite tier undercuts every Western competitor. US teams should weigh the Premium tier against Aurora and SurgePV before committing.
Where It Falls Short
Users report missing features, performance issues, and occasional instability. API access requires Premium or Enterprise tiers. Utility-scale capability is limited, and new construction areas may lack satellite imagery.
Key Features
- Native CRM with lead tracking and business analytics
- LiDAR-based 3D modeling with shading reports
- NEC-compliant permit packages in 48 hours with PE stamps
- ArkaGo mobile app for field proposals and lead management
Pricing
- Basic (US): $199/month — 1 user, residential and commercial design
- Premium (US): $358/month — 2 users, battery sizing, CAD export
- India Lite: ₹46,000/year — 360 residential projects
- Free trial: Not publicly listed; contact sales for evaluation access
Who Should Use Arka360
Strong fit: Small and mid-size EPCs in India and emerging markets needing design, CRM, and permits in one affordable platform.
Probably not right for: Large enterprises needing deep engineering validation and utility-scale developers.
9. Scanifly — Best Tool for Drone-Based Design
Scanifly is the only drone-first design platform built specifically for solar. Its drone shading tool holds nationwide regulatory approval from NYSERDA, MassCEC, and the CEC.
What It Does Well
Accuracy is the headline. Drone photogrammetry delivers 1–3 inch measurements across X-Y-Z planes. Namaste Solar cut its revision rate from 25% to under 1% after switching.
The 2-stage workflow splits sales from engineering. PrelimDesign produces proposal-ready layouts from satellite imagery. DroneDesign then verifies everything onsite before installation, with a 100% fitment guarantee.
Field time drops sharply. Hammond Energy cut survey work from 16 hours to 2.5 hours. The free mobile app handles checklists, photo annotation, and drone image submission.
Integrations cover the sales side of the workflow. Energy Toolbase, SubcontractorHub, and Enerflo connect for proposals. Zapier adds 5,000+ no-code app connections.
Our Take: If fitment errors and truck rolls are eating your margin, Scanifly pays for itself. EmPower Solar reported a 53% software cost reduction after switching from Aurora.
Where It Falls Short
Subscription pricing is not public, which slows evaluation. Processing needs a capable desktop workstation, and poor image quality stalls jobs. There is no native battery design, CRM, or proposal engine — pair it with Energy Toolbase or a proposal tool.
Key Features
- Drone photogrammetry with 1–3 inch measurement accuracy
- NYSERDA-approved Viewshed shading analysis
- 2-stage PrelimDesign and DroneDesign workflow
- Racking integrations with IronRidge, K2 Systems, and Unirac
Pricing
- Subscription: Custom quotes — contact sales for platform pricing
- Design services: Credit-based; residential site modeling from 15 credits
- Free trial: Not listed publicly; Scanifly Academy training is free
Who Should Use Scanifly
Strong fit: Residential and C&I installers who want drone-verified accuracy and fewer installation-day surprises.
Probably not right for: Utility-scale developers, teams without drone operations, and anyone needing an all-in-one sales platform.
10. Energy Toolbase — Best Tool for Financial Modeling
Energy Toolbase is the reference platform for solar + storage financial analysis. Over 1,500 distributed energy organizations use it for utility rate and project economics work.
What It Does Well
The utility rate database is the deepest available. It covers 70,000+ rates across 1,200+ territories, maintained by a dedicated in-house team. NEM 1.0, 2.0, and 3.0 modeling is built in.
Storage economics are a specialty. The platform models demand charge reduction, TOU arbitrage, and grid services in one cash flow. Acumen EMS adds machine-learning battery dispatch with 15-minute forecast updates.
Integrations cover the workflow gaps. Import 8760 data from HelioScope, Aurora, Scanifly, PVsyst, or PVWatts. Instant PPA quotes come from financing partners like Sunstone Credit.
The company itself is stable. Parent Pason Systems trades on the TSX. The ETB Developer price held flat for 10 years before a 2024 increase.
Our Take: Energy Toolbase is not a design tool — it is the tool that makes your design tool’s economics defensible. C&I developers selling on savings should treat it as required infrastructure.
Where It Falls Short
There are no native design capabilities at all. You need HelioScope, Aurora, or Scanifly for layouts and shading. CRM integration is on the roadmap with no date, and there are no mobile apps.
Key Features
- 70,000+ utility rates across 1,200+ territories worldwide
- Solar + storage NPV, IRR, payback, and cash flow modeling
- Acumen EMS for battery dispatch optimization
- ETB Monitor for post-install savings verification
Pricing
- ETB Developer: $199/user/month — unlimited proposals, 10% annual discount
- Acumen EMS and ETB Monitor: Custom quotes per project
- Free trial: Demo only; ETB Consulting offers pay-as-you-go analysis
Who Should Use Energy Toolbase
Strong fit: C&I developers, ESCOs, and financiers who need defensible savings models for solar + storage.
Probably not right for: Teams wanting one tool for design and financials, and residential-only shops on tight budgets.
Decision Flowchart: Which Alternative Fits Your Segment?

| Utility-scale EPC with AutoCAD engineers | PVcase Ground Mount + PVsyst |
| Financed project needing lender approval | PVsyst (required), plus any layout tool |
| C&I projects 100 kW–5 MW, no AutoCAD | HelioScope or SurgePV |
| Residential + C&I with proposals in one tool | SurgePV |
| US enterprise residential sales org | Aurora Solar |
| Startup or zero software budget | OpenSolar |
| California residential, NEM 3.0 focus | Solargraf |
| India or emerging-market EPC | Arka360 |
| Installers losing margin to fitment errors | Scanifly |
| Selling C&I on savings and storage economics | Energy Toolbase |
How to Choose the Right RatedPower Alternative
Start with segment, not features. RatedPower serves utility-scale; switching to a rooftop tool for a 100 MW pipeline trades one problem for another.
1. Define your project mix. If 80% of revenue is residential and C&I rooftops, utility-scale engineering depth is wasted spend. Pick SurgePV, Aurora, or HelioScope.
2. Check lender requirements. Financed projects above 10 MW almost always require PVsyst reports. Confirm before you drop a bankable tool.
3. Calculate total stack cost. Add CAD licenses, proposal tools, and per-seat fees. A $159/month tool plus AutoCAD plus a proposal platform can exceed a single all-in-one subscription.
4. Trial on a real project. Run the same site through 2 finalists. Compare yield outputs, design time, and proposal quality before signing annual contracts.
