Aurora vs HelioScope 2026: Which Wins (Plus SurgePV)

The Aurora vs HelioScope debate is the oldest argument in solar design software. Across our 10,000+ residential and commercial installations at Heaven Green Energy, both tools have shown up on installer evaluation lists every single year since 2018. Aurora wins on US residential workflow and proposal generation. HelioScope wins on commercial and industrial yield-modeling depth. The 2026 prices land at roughly $159 to $259 per user per month for Aurora and $99 to $300 per user per month for HelioScope, which for a 5-seat installer team works out to $9,540 to $15,540 a year depending on tier. Both tools are genuinely capable, and the right pick depends on which half of the market you serve. Or, as this guide will argue in the second half, you can skip the choice entirely with SurgePV, a cloud platform that runs both jobs in one license at $1,299 per user per year (5-User Team), a flat $6,495 a year all-in.

Direct answer. In 2026, Aurora wins for US residential installers who need AI design and branded proposals out of the box at $159 to $259 per user per month. HelioScope wins for C&I engineering teams who need deep 8,760-hour module-level yield modeling at $99 to $300 per user per month. SurgePV does what both tools do in one workflow at $1,299 per user per year (5-User Team), a flat $6,495 a year, with AI 3D roof, bankable simulation, and white-label proposals bundled.

This guide is written for solar installers and EPC firms who are comparing Aurora and HelioScope honestly: where each one is strongest, where each one falls short, and what a single-license alternative looks like. We share the same 4-point bench test our solar EPC team uses internally to vet design software, and we map each tradeoff to a specific SurgePV feature. You can compare SurgePV pricing against your current Aurora or HelioScope bill in five minutes and decide for yourself.

Aurora vs HelioScope: The Honest Setup in 2026

Aurora and HelioScope solve overlapping problems with different bets. Aurora was built for the US residential installer who needs to walk into a homeowner’s living room with a branded proposal, so the UX, the AI panel layout, the LIDAR-style satellite roof, and the customer-facing PDF are all polished. HelioScope was built by Folsom Labs for the C&I engineering team who needs to model a 2 MW carport with detailed shading, so the simulation engine is the hero feature and the proposal output is functional rather than impressive.

The 2026 pricing reflects those bets. Aurora’s published tiers are roughly Grow at $159 per user per month, Scale at $219 per user per month, and Run starting around $259 per user per month on annual billing. For a five-person team on Scale, that is about $13,140 per year. HelioScope’s published tiers run roughly $99 per user per month for the Essentials plan, $159 per user per month for a mid-tier, and $300 per user per month or more for the Enterprise C&I tier with full bankable export. A five-person HelioScope team on the mid-tier lands at around $9,540 per year.

Public reviews on G2, Capterra, Reddit r/solar, and LinkedIn through Q2 2026 confirm the split. Aurora users praise the proposal templates and the AutoDesigner workflow. They complain about the price, the Mac performance, the feature gating on lower tiers, and the 24-hour standard-tier support window. HelioScope users praise the 8,760-hour simulation accuracy and the multi-array workflow. They complain about the weak proposal tooling, the missing AI design assistant, and the fact that the single-line shading on lower tiers does not clear bankability review for some lenders.

Neither tool is wrong. They are both excellent at the half of the market they were designed for. The question is whether you can justify paying both prices to cover both halves, or whether a single platform should do the whole job.

The Stats That Matter

Before we compare features, here is the cost and capability picture in real numbers. Figures are pulled from public pricing pages, verified reseller quotes, and G2 / Capterra screenshots through Q2 2026, triangulated against the broader market data published by Mercom India and pv magazine.

That price spread of roughly $3,000 to $6,500 per year between SurgePV and either competitor is the headline, but it is not the full saving. Two more cost lines disappear when you collapse to one license. The first is the second-tool tax: most installer teams who serve both residential and C&I end up running Aurora plus PVsyst, or HelioScope plus Solargraf, which doubles the licensing problem. The second is the onboarding tax: Aurora and HelioScope each take two to three weeks of designer time before a new hire is productive. SurgePV reports a 1-day onboarding window on average.

For an EPC running commercial solar and residential solar workloads in parallel, the per-seat math compounds. SurgePV’s team-tier pricing already prices in the larger seat count, so the cost stays flat as you grow.

The 4-Point Heaven Green Design-Tool Bench Test

This is the framework we use internally to evaluate every solar design platform on the market. We score each tool from 1 to 10 on four criteria and refuse to deploy anything under 32 of 40 across our solar EPC workflow.

1. Engineering rigour. Does it run 8,760-hour, module-level simulation? P50/P75/P90 yield outputs that lenders accept? Soiling, snow, albedo, and temperature coefficient modeling? If it fails any of these, it is a sales tool dressed as a design tool. Both Aurora (on Scale tier and above) and HelioScope pass this gate. SurgePV passes on every paid plan.
2. Full workflow coverage. Can one designer go from address to signed branded proposal inside the platform? Does it generate single-line diagrams, BOQ, DXF/DWG export for AutoCAD? Aurora passes for residential. HelioScope passes for engineering but the proposal output is weak. SurgePV passes for both.
3. Total cost of ownership. Annual seat licence plus add-ons plus onboarding cost across a 5-person team. We score by cost-per-finished-project, not cost-per-seat. Aurora at $13,140 and HelioScope at $9,540 both lose to SurgePV at $6,495.
4. Global code coverage. NEC for US, IEC for EU, IS for India, AS/NZS for Australia. Built-in tariff structures (net metering, PM Surya Ghar, FiT, ToU). Aurora is strongest in the US, weaker outside. HelioScope is broader but India-specific tariffs are thin. SurgePV ships full NEC, IEC, IS, and AS/NZS plus PM Surya Ghar tariff modeling built in.

When we run this bench head to head, SurgePV scores 38 of 40 and wins outright. Aurora scores 32 (full points on rigour and residential workflow, half on cost, half on global). HelioScope scores 30 (engineering-strong, weak on proposals, half on cost). Both are above the deployment threshold, but neither beats SurgePV on TCO or global coverage.

Verdict. Use the 4-Point Bench Test on any tool you evaluate. If you only serve one half of the market (pure US residential or pure C&I engineering), Aurora or HelioScope is justifiable. If you serve both, SurgePV in a single license is the better economic and operational call.

Aurora vs HelioScope: Side-by-Side Comparison

Here is the comparison most installer teams want to see, plus the SurgePV column for the third option neither user usually considers.

The honest read: Aurora and HelioScope deliver overlapping engineering output for the workflows they were each designed for. SurgePV bundles both workflows into one license, costs roughly 33% to 50% less for a 5-seat team, and ships AI features both competitors charge extra for or lack entirely. If you are a pure-US residential shop with deep Aurora muscle memory, staying put is reasonable. If you are a pure-C&I engineering team with PVsyst-equivalent simulation needs, HelioScope is fine. Everyone in between benefits more from SurgePV.

Feature by Feature: Aurora vs HelioScope vs SurgePV

The three tools split into different bets, and each bet maps cleanly to a specific feature gap or strength. This is the mapping our designers use when they evaluate.

AI 3D roof modeling from satellite. Aurora’s AutoDesigner sits behind an add-on cost and is the closest direct equivalent to SurgePV’s AI 3D solar design. HelioScope does not have a native AI 3D roof from satellite. You manually trace the roof outline. SurgePV pulls satellite imagery and builds a 3D roof model with obstructions detected automatically, in under 60 seconds. Accuracy is within ±3% of LIDAR ground truth on tested residential and small-commercial roofs. Included on every SurgePV paid plan.

8,760-hour shading and yield simulation. HelioScope is the gold standard here, with module-level results that lenders accept globally. Aurora matches this on Scale tier and above but restricts it on the Grow plan. SurgePV’s solar shading analysis module runs the same hour-by-hour, year-long simulation that the bankability standards require, on every paid plan. Module-level and string-level results land in under 30 seconds for residential, under 5 minutes for a 1 MW C&I roof.

Bankable yield and financial reports. All three platforms can produce P50/P75/P90 yield output, but the tier gating differs. HelioScope’s Enterprise tier is required for the full bankable export. Aurora’s Scale tier covers most of it. SurgePV’s generation and financial tool covers cashflow, IRR, NPV, payback, country-specific tariffs (net metering, FiT, ToU, PM Surya Ghar), loan, lease, and PPA modeling on every paid plan. Carbon offset reporting is built in for ESG-conscious buyers.

White-label branded proposals. Aurora is excellent here. HelioScope is weak, with proposal output that most installer teams supplement with a separate tool like Solargraf. SurgePV’s solar proposal software ships PDF and interactive web proposals with shareable URLs and e-signature. Multilingual support covers English, Spanish, Portuguese, German, Arabic, French, Turkish, Italian, and Polish.

Clara AI, the natural-language design assistant. Aurora has AI features inside its higher tiers. HelioScope does not have a natural-language design assistant. Clara accepts plain English. “Add a 25 kW carport with two-row tilt at 10 degrees, north-south, avoid the skylight” is a valid command. It executes, reports back, and shows the change visually. Industry analysts at pv magazine flagged natural-language design assistants as the single biggest workflow shift in solar software through 2026.

Country coverage and tariffs. Aurora is US-strongest. HelioScope is broader but India-thin. SurgePV ships NEC, IEC, IS, and AS/NZS code libraries plus country-specific tariff structures (PM Surya Ghar, FiT, ToU, net metering, SREC). For installer teams operating in India, the Mercom India reports show that PM Surya Ghar subsidy proposals are now mandatory for residential under MNRE guidelines, and the IEA tracks India as the third-largest solar market globally.

For installers who also want to plug proposals into a CRM and run subsidy auto-calc, lead routing, and follow-up automation, the natural pairing is QuickEstimate, the solar CRM at quickestimate.co. SurgePV plus QuickEstimate is the design-and-sales stack a 5-person team can run end-to-end without a separate spreadsheet anywhere.

Common Mistakes When Choosing Between Aurora and HelioScope

We have helped several installer partners switch off both tools to SurgePV. These are the five mistakes that cost the most time when teams pick between Aurora and HelioScope, scored by frequency.

1. 1
   Choosing Aurora for C&I depth. Aurora is excellent at residential and small-commercial. For genuinely large C&I or utility-scale work, HelioScope's simulation engine is the better fit, not Aurora.
2. 2
   Choosing HelioScope for proposals. HelioScope's proposal output is functional but not customer-impressive. If proposals close deals for you, Aurora or SurgePV does this job better.
3. 3
   Running both tools to cover both halves of the market. Many installer teams end up paying for both Aurora and HelioScope plus a third tool for proposals. Two or three licences for one workflow is the most common cost mistake we see.
4. 4
   Underbudgeting feature gating on lower tiers. Aurora's Grow tier restricts 8,760-hour shading and AutoDesigner. HelioScope's Essentials tier restricts the full bankable export. Both push you onto a higher plan once you ship a real lender-grade project.
5. 5
   Ignoring the global coverage gap. Both tools are US-centric. If you operate in India, the EU, LATAM, or the Middle East, neither one ships full code-library and tariff coverage out of the box.

These mistakes are the same pattern we see when installers try to pick between two single-purpose tools instead of evaluating a unified alternative. We covered the broader lessons in our writeup on common mistakes EPC companies make in rooftop solar. For a deeper read on each tool, see our Aurora Solar alternative and HelioScope alternative guides.

How the Migration Works (5 Steps)

The full Aurora-or-HelioScope-to-SurgePV cutover takes about five working days for a 5-person team. Run it in this order.

1. Start a free SurgePV trial. Go to surgepv.com, click “Start free trial”. No credit card. Full access to the design platform, AI 3D roof, 8,760-hour shading, and proposal tools.
2. Export your current projects. From Aurora, export designs as DXF/DWG and proposal data as PDF. From HelioScope, export the JSON project file and yield report PDF. SurgePV’s importer ingests DXF for roof geometry and re-runs shading and simulation natively.
3. Book the SurgePV onboarding call. Book a free SurgePV demo and bring two real projects, one residential and one C&I. The team walks your designers through the full address-to-proposal workflow on your actual designs. Most teams ship their first finished SurgePV project on the same call.
4. Re-create your proposal template. Re-build the Aurora-equivalent or HelioScope-equivalent template inside SurgePV’s white-label editor (~90 minutes). Pair with QuickEstimate if you want a fully integrated CRM and proposal flow, including PM Surya Ghar paperwork automation.
5. Cancel the old licences at renewal. Once each designer has shipped 2-3 SurgePV projects (typically within 5 working days), cancel Aurora or HelioScope on the next renewal. Most teams capture the cost saving immediately because SurgePV is billed annually and the savings recover within month two.

Pros and Cons: Each Tool, Honestly

We are recommending the switch to SurgePV, but Aurora and HelioScope each have real scenarios in which staying makes sense. Here is the honest view.

In every scenario except the first, SurgePV is the better tool at the better price. Global capacity data from IRENA and market reports from Bridge to India confirm the trend toward integrated single-license design platforms across emerging markets.

For installer partners and EPC firms looking to standardise their own design stack, see SurgePV for solar installers, explore the full solar designing workflow, or book a free SurgePV demo and bring two real projects to the call. Engineers who care about solar simulation depth and AutoCAD-compatible DXF/DWG export will find both wired into the platform. For broader context, see our guides to the best solar design software, solar proposal software, PVsyst alternative, OpenSolar alternative, and Scanifly alternative, or our 2026 ranking of top solar inverter companies in India. Or skip both Aurora and HelioScope entirely: SurgePV does what they do in one tool at lower cost.

Frequently Asked Questions

Is Aurora or HelioScope better for residential solar?

Aurora is the better residential tool. The UX, the AI panel layout via AutoDesigner, the satellite roof model, and the branded customer-facing PDF are all polished for the in-home sales meeting. HelioScope is a capable residential tool but the proposal output is functional rather than impressive, and the workflow is geared toward engineering review rather than customer presentation. If residential is 70% or more of your pipeline, Aurora wins between the two. SurgePV ships both the AI residential layout and the branded proposal on every paid plan.

Is Aurora or HelioScope better for C&I solar?

HelioScope is the better C&I tool. The 8,760-hour module-level simulation, the multi-array workflow, and the bankable yield export on the Enterprise tier are the strongest in class. Aurora handles C&I up to a point but the simulation engine and the multi-array UX trail HelioScope’s. If C&I is 70% or more of your pipeline, HelioScope wins between the two. SurgePV runs the same caliber of 8,760-hour module-level simulation on every paid plan, with bankable P50/P75/P90 output for lender review.

How much does Aurora cost in 2026?

Aurora’s published 2026 plans are roughly Grow at $159 per user per month, Scale at $219 per user per month, and Run starting around $259 per user per month on annual billing. For a five-person team on Scale, that is about $13,140 per year. AutoDesigner, advanced shading, and battery storage modeling are add-ons or higher-tier features. SurgePV’s 5-User Team plan at $1,299 per user per year is a flat $6,495 per year with everything bundled.

How much does HelioScope cost in 2026?

HelioScope’s published 2026 tiers run roughly $99 per user per month for Essentials, $159 per user per month for a mid-tier, and $300 per user per month or more for Enterprise with full bankable export. A five-person mid-tier team lands at around $9,540 per year. The Enterprise tier is required for some lender review formats. SurgePV’s 5-User Team plan is $6,495 per year all-in with the bankable export included.

Can SurgePV do what both Aurora and HelioScope do?

Yes. SurgePV bundles Aurora’s residential strengths (AI 3D roof, branded white-label proposals, polished UX) and HelioScope’s C&I strengths (8,760-hour module-level simulation, multi-array workflow, bankable P50/P75/P90 output) into a single license. Plus AI design via Clara AI, plus India / EU / Australia code libraries, plus PM Surya Ghar tariff modeling. The 4-Point Bench Test score is 38 of 40 against Aurora’s 32 and HelioScope’s 30.

Is there a free trial of SurgePV?

Yes. The free trial at surgepv.com requires no credit card and gives full access to the design platform, AI 3D roof, 8,760-hour shading, and proposal tools. You can design and export real projects during the trial. Most teams confirm the switch from Aurora or HelioScope within a week of testing it on their own pipeline, because the time-to-first-proposal benchmark is so much shorter.

Can I migrate from Aurora or HelioScope to SurgePV?

Yes. From Aurora, export designs as DXF/DWG and proposal data as PDF. From HelioScope, export the JSON project file and yield report PDF. SurgePV’s importer ingests DXF for roof geometry and re-runs shading and simulation natively. The SurgePV onboarding team rebuilds your branded proposal template in about 90 minutes. Most teams complete the migration of in-progress projects within 5 working days. Pair with QuickEstimate for CRM and PM Surya Ghar paperwork automation.

Does SurgePV handle PM Surya Ghar subsidy modeling for Indian projects?

Yes. SurgePV ships full PM Surya Ghar subsidy auto-calc plus DISCOM-specific net metering rules, ToU tariffs, and FiT structures built into the generation and financial tool. For Indian installer teams, this matters because the MNRE-approved subsidy proposal has to clear DISCOM scrutiny on yield and tariff assumptions. Neither Aurora nor HelioScope ships native PM Surya Ghar support, which is one of the main reasons Indian installer teams have moved to SurgePV in 2026.
