Best HelioScope Software Alternative in 2026

Quick Answer

HelioScope Does Real Things Well

Credit where it's due: HelioScope's simulation engine is fast, users consistently describe designing and running a full simulation in minutes, and Sunstone Credit recognized it as bankable in October 2025, the first web-based solar platform to earn that from a major lender. For a US C&I team working strictly within its scope, that's a real, legitimate credential.

How HelioScope Got Here

HelioScope was built by Folsom Labs as an independent product before becoming part of Aurora Solar's portfolio. That matters for what to expect going forward: it's now a C&I-focused product line inside a larger company whose flagship platform, Aurora itself, is the one your own comparison page already covers. Two products from the same parent company competing for the same roadmap priorities is a reasonable explanation for why HelioScope has stayed narrowly scoped, fast simulation and bankability for C&I, rather than expanding into mobile field design or broader project-type coverage.

For a buyer evaluating both, that raises a practical question worth asking directly: if a project ever needs something outside HelioScope's current scope, mobile field design, residential support, battery co-optimization, the more likely path is Aurora's own platform absorbing those capabilities over time, not HelioScope's. Evaluating HelioScope today means evaluating what it actually does right now, not what it might eventually inherit from the platform it sits under.

No Mobile Design Capability

HelioScope has no mobile design capability. The workflow, drawing field segments, assigning modules and inverters, reviewing electrical warnings, running the simulation, is built for a desk session. Reslink's design workflow runs identically on a phone, tablet, or desktop, not a stripped-down field version of a desktop tool, the same full capability on either.

No Native Bills of Structure

HelioScope doesn't generate Bills of Structure on its own. Its published integration list names Unirac U-Builder specifically for structural takeoffs, mounting rails, clamps, fasteners, meaning a second tool and a second data hand-off before procurement can happen. Reslink generates both Bills of Electrical and Bills of Structure automatically from the same 3D model, with no second tool required.

Capped at 5 MW, Priced by the Project

HelioScope's Basic plan caps at 1.25 MW and 10 projects a month, at $159/month for one user. Run the math on a mid-size EPC doing 15 C&I projects a month, which is a modest, realistic volume: that team exceeds both the project cap and, on most projects, the scale cap, inside a single month, forcing an upgrade to a higher, undisclosed-pricing tier before month one is even finished. Reslink has no equivalent scale ceiling forcing a plan change as project volume grows.

Battery Storage Is Core Design Now, Not an Add-On

Over 40% of US residential solar installations now include storage, according to Aurora Solar's own 2026 market data, so treating battery sizing as a step bolted onto an already-finished PV layout is no longer a reasonable workflow, even though that's how most design software still handles it, if it handles it at all.

Reslink builds battery sizing directly into the same 3D design session as the panel layout, live, not a roadmap item:

• Chemistry-aware sizing. LFP and NMC batteries have different usable-capacity math at the same nominal rating, a 10 kWh LFP battery delivers close to its full nameplate capacity, a 10 kWh NMC battery typically delivers 8 to 9 kWh usable, depending on depth-of-discharge limits. Reslink applies the correct math for the selected chemistry automatically.
• Critical-load backup modeling. Reslink models which loads, refrigeration, well pumps, essential circuits, stay powered during an outage, and for how long, based on the actual battery size and the customer's real load profile, not a generic backup-hours estimate.
• Commercial demand-charge and peak-shaving sizing. For C&I customers, a battery's real financial case is usually demand-charge avoidance, not energy arbitrage. Reslink sizes the battery to keep a facility's peak draw under a target threshold, tied to the customer's actual tariff structure, and reflects that math directly in the proposal.
• Co-optimization with the PV array, in the same session. Because battery sizing runs inside the same mobile 3D design workflow as the panel layout, an EPC isn't running solar design in one tool and storage sizing in a second one, then reconciling the two by hand.

Take a mid-size commercial customer with a 200 kW peak demand and a demand charge of $15/kW-month, a realistic rate across much of the US. Shaving that peak by 40 kW with a correctly sized battery saves $600 a month, over $7,000 a year, in demand charges alone, before counting any energy arbitrage. Size that battery wrong in either direction, too small to shave the real peak, or oversized and adding cost with no return, and it shows up directly in the customer's bill, and in the EPC's credibility on the next referral.

This is the actual complaint in the market right now, not whether a tool can model a battery, but whether the array and the battery get sized together, in one workflow, in a way a lender will accept. HelioScope's own feature list doesn't describe this capability at all.

Beyond the US: The Same Workflow in the UK, Europe, Australia, and the Middle East

HelioScope's published feature set is built around US standards specifically: NEC-compliant electrical calculations, US utility rate structures, US-format documentation. That's a reasonable choice for a product built for the US market, but it means an EPC operating across multiple regions is working around the tool's home-market assumptions everywhere else, reformatting documentation, re-checking compliance requirements, and re-deriving financial assumptions market by market.

Reslink's platform loads local irradiance data, grid codes, compliance formats, and financial parameters automatically based on where a project sits, not as a separate configuration step layered on top of a US-first design. In the Middle East specifically, this includes generating documentation in DEWA-accepted format for UAE projects, the same way it generates DISCOM-format documentation for Indian projects, without the EPC manually reformatting anything. An EPC designing a rooftop system in Manchester, a commercial array in Dubai, and a residential project in Melbourne is running the same mobile workflow, the same battery-sizing logic, and the same proposal generation in all three, with the platform adjusting the underlying data behind it rather than the EPC adjusting their process for each market.

Reslink vs HelioScope: Feature Comparison

Real EPCs Have Made This Switch

Freyr Energy, backed by Schneider Electric, moved its entire residential sales team to Reslink specifically for the mobile-first design-to-delivery workflow. CleanMax partnered with Reslink as part of its EPC operations. Both are Indian EPCs, worth being upfront about, so if you're evaluating this from a US or European base, treat these as evidence Reslink's workflow holds up in a live, high-volume environment, not as a market-specific reference. The underlying workflow being validated, mobile field design, automated documentation, one platform across project types, is the same workflow running in every active market, not a version specific to any one of them.

What EPCs Should Do Now

Where Reslink Fits Once You've Hit HelioScope's Limits

HelioScope's caps and desk-bound workflow show up as real costs the moment a pipeline includes anything outside narrow C&I: a residential inquiry it can't price, a battery quote that needs a second tool or a manual estimate, a site visit that ends with a design engineer back at a desk instead of a proposal in hand.

Reslink runs the same 3D design and simulation ground HelioScope covers, then continues past it: automated BOE and Bills of Structure from the same model, an NEC-compliant SLD that regenerates on every design change, battery sizing co-optimized with the array from day one, and a mobile workflow that lets a salesperson go from design to proposal in a single visit, on any project size the platform supports.

Frequently Asked Questions

Q1. Does HelioScope have a mobile app?

No. HelioScope has no mobile design capability. It's accessible from a mobile browser, but the design workflow itself is built for a desk session, not a field visit.

Q2. Can HelioScope size battery storage as part of the design?

Not as a documented native feature. HelioScope's own published feature list covers 3D design, energy simulation, a financial calculator, and proposal export, battery or storage sizing isn't described among them.

Q3. What does "co-optimized" battery sizing actually mean?

It means the battery is sized inside the same design session as the solar array, using the same load profile and layout data, rather than sized separately and reconciled by hand afterward. Reslink handles chemistry-specific sizing (LFP vs NMC), critical-load backup modeling, and commercial demand-charge sizing, all inside the same 3D design workflow used for the PV layout.

Q4. Can HelioScope generate a full Bill of Materials?

Not on its own. Its integration list names Unirac U-Builder specifically for structural takeoffs, meaning Bills of Structure require a second tool. Electrical takeoffs aren't described as a native output either.

Q5. How much does HelioScope cost compared to Reslink?

HelioScope's Basic plan is $159/month for one user, capped at 10 projects a month and 1.25 MW. Reslink's current plans and pricing are at /pricing/.

Q6. Does HelioScope work for residential solar projects?

No, it's priced and positioned specifically for commercial and industrial work. Reslink covers the same C&I range plus residential, from 3 kW, on one platform.

Q7. Does Reslink work outside the US?

Yes. Reslink runs the same workflow across the UK, Europe, Australia, and the Middle East, without switching tools or losing capability on any device.

Q8. Does Reslink's coverage in the UK, EU, Australia, and the Middle East match its US capability exactly?

Yes. The design, proposal, BOM, and battery-sizing workflow is identical across every active market. What changes automatically behind the scenes is the local data layer, irradiance figures, grid codes, compliance document formats, and utility tariff structures, not the workflow the EPC actually uses.
