Searching for the best solar software in USA usually means one of two things: you are replacing a tool that is costing too much, or you are building a stack from scratch and do not yet know how many licenses you need. American solar software is not one category. It is six overlapping ones (design, simulation, sales and proposals, permitting, field operations and monitoring) and the platforms that claim to cover all six rarely do. Our ranking puts SurgePV first at $1,299 per user per year on the 5-User Team plan because it covers five of those six layers credibly in one license, which is the closest anyone gets. But the honest answer for a US installer is that you will run two or three tools, and the skill is choosing which ones.
Direct answer. The best solar software in USA for 2026 is SurgePV, at $1,299 per user per year on the 5-User Team plan, covering 3D design, 8,760-hour simulation, NEC 2023 plan sets, ITC and MACRS financials and white-label proposals in one license. Aurora Solar is the deepest US-native alternative at $135 per user per month on Basic and $220 on Premium, both billed annually, while PVsyst, HelioScope, Scanifly, GreenLancer and AlsoEnergy each own a specialist layer no all-in-one tool replaces.
This page ranks ten platforms with 2026 USD pricing, the layer each one owns, the buyer it fits and where it falls down. It is deliberately broader than our solar design software USA comparison, which covers design tools only, and than the best solar proposal software in USA roundup, which covers the sales layer. Read this one first if you are deciding what the whole stack looks like.
What Counts as Solar Software in the US Market
American solar work generates six distinct software jobs, and conflating them is the most common reason installers overspend.
Design is array layout on a real roof or parcel: obstruction detection, setbacks, tilt and azimuth, string configuration, equipment selection from a UL-listed component library. Simulation is the yield question: an 8,760-hour hourly model producing P50, P75 and P90 output that a lender will underwrite against. Sales and proposals is the customer-facing document with financing, incentives and e-signature. Permitting is the AHJ plan set: site plan, roof plan, single-line diagram, structural details, equipment cut sheets and NEC labeling. Field operations covers scheduling, crew dispatch, punch lists and commissioning records. Monitoring is the 25-year job: production data, alerting, performance ratio tracking and warranty evidence.
The US market matters here because each layer carries country-specific requirements. NEC 2023 is now adopted in over 40 states, and it changes rapid shutdown, string sizing and labeling in ways that flow through design, permitting and monitoring alike. The National Renewable Energy Laboratory maintains the code adoption reference most designers use, and the U.S. Department of Energy publishes the federal incentive framework that the financial layer has to encode.
💡 Fast tip
Write down which of the six layers is actually slowing your business down before you look at a single demo. Most installers buy a design tool to solve a permitting bottleneck and stay slow.

Each platform gets one point per layer it covers to a professional standard, plus a weighted score for US-specific depth. We call it the 6-Layer US Stack Score, and it is the framework our design team applies before adding any tool to our own workflow.
- Design at a standard where the layout survives structural and electrical review.
- Simulation producing hourly P50, P75 and P90 output a US lender accepts.
- Sales and proposals with white-label branding, financing options and e-signature.
- Permitting producing an AHJ-ready plan set with NEC 2023 labeling and a single-line diagram.
- Field operations covering scheduling, crew dispatch and commissioning records.
- Monitoring with production data, alerting and performance ratio reporting.
Layer coverage out of 6: SurgePV 5, Aurora Solar 4, HelioScope 2, PVsyst 1, Scanifly 3, OpenSolar 3, Solargraf 3, Sunbase 3, GreenLancer 1, AlsoEnergy 1. Coverage alone does not decide the ranking. A tool that owns one layer completely (PVsyst on simulation, AlsoEnergy on monitoring) can be more valuable to a specific business than a platform covering four layers adequately.
The Top 10 Solar Software Platforms in the USA
Pricing below is 2026 published or reseller-quoted USD. Several vendors negotiate at five seats and above, so treat these as starting points.
1. SurgePV
What it does best. Collapsing four layers into one license. Enter a US address, get an AI-built 3D roof from satellite imagery in under a minute, auto-place modules with NEC 2023 setbacks applied, run the 8,760-hour module-level simulation for P50, P75 and P90 yield, apply the 30 percent ITC with IRA adders and MACRS depreciation, and generate both a white-label interactive proposal and the single-line diagram and bill of materials the permit team needs. Clara AI accepts plain-English design commands, and DXF export hands off cleanly to the structural engineer of record.
Real pricing. $1,899 per user per year on Individual, $1,299 per user per year on the 5-User Team plan ($6,495 for five seats), custom on Enterprise. Free trial, no credit card.
Who it suits. US installers and EPCs doing five or more projects a month, particularly multi-state teams and anyone mixing residential with commercial work where the depreciation math matters.
Honest limitations. SurgePV does not do monitoring, so you still need a hardware-native or third-party platform for the 25-year operations job. Field operations coverage is lighter than a dedicated dispatch tool. The US template library is younger than Aurora’s, brand recognition among long-established American installers is still developing after the early-2025 launch, and native lender credit integrations are thinner than Enact’s. For utility-scale yield reports where a specific bank insists on PVsyst output, SurgePV is a complement rather than a replacement.
2. Aurora Solar
What it does best. US-native depth. A decade of American roof geometry, the widest built-in US utility rate schedule library, AutoDesigner AI trained on US residential roofs, and lender familiarity that removes friction from financed deals.
Real pricing. Aurora publishes two named plans. Basic is $135 per user per month billed annually ($1,620 per user per year, or $159 month to month) and Premium is $220 billed annually ($2,640 per user per year, or $259 month to month), each covering one user and 50 projects a month. Enterprise is quoted. Five Basic seats is $8,100 a year and five Premium seats is $13,200. Basic at $1,620 per user per year is cheaper than SurgePV’s $1,899 Individual plan, and five Basic seats sit above SurgePV’s $6,495 five-seat price by about $1,600.
Who it suits. Established US residential and C&I installers with trained teams and template libraries already built around Aurora.
Honest limitations. Per-seat pricing scales linearly, LIDAR modelling, bankable shade reports and battery modelling require Premium rather than Basic, plan sets are a separately priced service rather than a plan inclusion, site models start at $9.99, and designer onboarding runs two to three weeks. Our Aurora Solar alternative analysis covers the total cost comparison.
3. HelioScope
What it does best. Commercial and industrial yield modeling. HelioScope’s simulation engine and component library are trusted by American engineers for C&I arrays, and its wiring and loss reporting is unusually transparent.
Real pricing. Basic is $159 per user per month ($1,620 per year) and Pro is $259 ($2,640 per year), each covering one user and 10 projects a month, with DC design capped at 1.25 MW on Basic and 5 MW on Pro. Enterprise is quoted. Five Basic seats is $8,100 a year and five Pro seats is $13,200.
Who it suits. Engineering consultancies and in-house C&I design teams producing yield reports for others to package.
Honest limitations. Proposal tooling is minimal, there is no white-label interactive proposal or e-signature, and residential workflow is not its strength. Expect a second license. See our HelioScope alternative comparison.
4. PVsyst
What it does best. Bankability. PVsyst remains the reference simulation tool for utility-scale and large C&I projects, and many US project finance lenders and independent engineers still ask for a PVsyst report by name.
Real pricing. PVsyst bills in Swiss francs. Professional is CHF 700 per user per year on an annual subscription, not a perpetual licence, with group discounts of 5 to 20 percent by quantity. Five seats is CHF 3,500, which is less than SurgePV’s $6,495 for five. PVsyst produces no proposals, no plan sets and no sales layer, but on licence cost alone it is the cheaper product and it is worth saying so.
Who it suits. Independent engineers, developers and anyone producing yield reports for tax-equity or debt financing on utility-scale projects.
Honest limitations. Windows desktop software with a steep learning curve, no proposal or sales layer, no permitting output, and modeling is slow compared with cloud tools. Reading the loss diagram correctly is its own skill; our sister engineering team covers it in how to read a PVsyst loss diagram. See also our PVsyst alternative guide.
5. Scanifly
What it does best. Drone-based site capture. Scanifly turns a drone flight into a photogrammetry model of the actual roof, which produces measurements and shading inputs from real conditions rather than satellite estimates. It also reduces the number of physical site visits.
Real pricing. Not publicly listed. Scanifly quotes by volume and publishes no price table, so any per-seat or per-project figure you see quoted elsewhere is an unverified third-party estimate rather than a vendor number.
Who it suits. Installers working complex roofs, older housing stock or commercial sites where satellite geometry is unreliable, and teams that want to cut truck rolls.
Honest limitations. You need drones, trained pilots and FAA Part 107 certification. Cost per project is high for straightforward residential work, and it complements rather than replaces a design and proposal platform.
6. OpenSolar
What it does best. A free design and proposal base tier, funded by hardware partner referrals rather than subscriptions.
Real pricing. The core platform is free, and on licence cost that makes OpenSolar cheaper than SurgePV outright. From 16 April 2026 OpenSolar charges for API Access (per project, charged on project creation) and for Connectors (a flat monthly fee), but it does not publish those rates and they vary by country, so the stacked cost of a full setup cannot be stated honestly without a quote.
Who it suits. Solo installers and very small residential shops in simple jurisdictions.
Honest limitations. Commercial capability is limited and the code library update cadence is not something to bet a permit submission on. Because the paid API and Connector rates are unpublished, you cannot budget a full OpenSolar setup from the website. Our OpenSolar alternative guide covers the trade-off.
7. Solargraf
What it does best. Fast residential proposals with permit-package add-ons, and a tight Enphase microinverter and battery workflow given the Enphase ownership.
Real pricing. Sold in project-volume plans, not per seat. Starter is $2,799 for 240 projects and 2 users, rising to Enterprise at $12,999 for 1,500 projects. API access is $4,000 a year on every plan except Enterprise.
Who it suits. Residential installers optimizing for time from appointment to proposal.
Honest limitations. Light shading and yield modeling, thin commercial capability, and a proposal number that can drift from the engineered number when a separate design tool is in play.
8. Sunbase
What it does best. Field and sales operations. Lead capture, canvassing routes, crew scheduling, commission tracking and follow-up automation in one system, with proposal generation attached.
Real pricing. Sunbase states an entry price of $59 per user per month and does not publish its tiers. Any wider range is an industry-observed estimate rather than a vendor figure.
Who it suits. Installers whose bottleneck is pipeline and crew coordination rather than engineering.
Honest limitations. Design and simulation are basic, so it sits alongside a real design platform. If you are evaluating this layer specifically, this solar CRM selection guide sets out the criteria worth scoring.
9. GreenLancer
What it does best. Permit plan sets and professional engineer stamps as a service. You submit project data, GreenLancer returns an AHJ-ready package with PE and structural stamps where required, across most US jurisdictions.
Real pricing. Not publicly listed. GreenLancer prices per plan set rather than per seat, but publishes no rate card on its own site, so the cost of a residential package depends on a quote covering stamping scope and turnaround.
Who it suits. Installers expanding into new states who do not want to learn every AHJ’s requirements or retain in-house PEs in each jurisdiction.
Honest limitations. It is a service, not software you control. Turnaround depends on their queue, per-project cost adds up at volume, and revisions cost time. At high volume, in-house plan sets from a design platform are cheaper. Our sister engineering practice publishes a useful primer on California AHJ solar permitting if you are weighing in-house against outsourced.
10. AlsoEnergy PowerTrack
What it does best. Commercial and utility-scale monitoring. Hardware-agnostic data acquisition, performance ratio tracking, alerting, availability reporting and the production evidence that settles warranty and performance-guarantee disputes.
Real pricing. Not publicly listed. AlsoEnergy publishes no plan table or rate for PowerTrack and routes every enquiry to sales, so budget it from your own quote. AlsoEnergy has been owned by Stem, Inc. since Stem completed the acquisition on 1 February 2022.
Who it suits. Asset owners, O&M providers and EPCs carrying performance guarantees on commercial and utility-scale portfolios.
Honest limitations. No design, simulation, proposal or permitting capability at all. Overkill for residential portfolios, where inverter-native monitoring from Enphase, SolarEdge or the string inverter vendor is usually adequate.
All 10 Compared: Price, Layer and Best Fit
The table below is the fastest way to see which layer each platform owns and what it costs in USD.
| # | Platform | 5-seat annual cost (USD) | Layers covered | Key capability | Best for |
|---|---|---|---|---|---|
| 1 | SurgePV | $6,495 | Design, simulation, proposals, permitting, part of field ops | One model from address to proposal to plan set | Multi-state US installers and EPCs |
| 2 | Aurora Solar | $8,100 Basic, $13,200 Premium | Design, simulation, proposals, part of permitting | Deepest US rate and roof library | Established US residential and C&I firms |
| 3 | HelioScope | $8,100 Basic, $13,200 Pro | Design, simulation | Transparent C&I loss reporting | Engineering consultancies |
| 4 | PVsyst | CHF 3,500 (CHF 700 per user per year) | Simulation | Lender-recognized bankable yield reports | Utility-scale developers and IEs |
| 5 | Scanifly | Not publicly listed | Site capture, design, field ops | Drone photogrammetry of the real roof | Complex roofs, truck-roll reduction |
| 6 | OpenSolar | Free core platform, paid API and Connector rates unpublished | Design, proposals, part of sales | Free base tier | Solo residential installers |
| 7 | Solargraf | $2,799 Starter to $12,999 Enterprise, by project volume | Proposals, part of design, permitting add-on | Fast residential proposals | Residential-only shops |
| 8 | Sunbase | From $59 per user per month, tiers unpublished | Sales, field ops, basic proposals | Crew and pipeline coordination | Operations-constrained installers |
| 9 | GreenLancer | Not publicly listed, priced per plan set | Permitting | Stamped AHJ plan sets as a service | Installers entering new states |
| 10 | AlsoEnergy | Not publicly listed | Monitoring | Performance ratio and availability reporting | Asset owners and O&M providers |
Verdict. Rank by the layer that is costing you money, not by feature count. If proposals and permits are slow, SurgePV or Aurora. If a bank is asking for a specific report format, PVsyst. If crews and scheduling are the mess, Sunbase. If a 20 MW portfolio is underperforming and nobody can prove why, AlsoEnergy.
What US Solar Software Must Encode: Code, Interconnection and Listing
A tool built for another market will fail an American project in specific, predictable ways.
NEC 2023 is now the adopted cycle in over 40 states, with the rest on 2020 or 2017. Article 690.12 sets module-level rapid shutdown requirements that constrain which optimizers, microinverters and rapid shutdown devices are usable. Article 690.7 and 690.8 govern maximum voltage and current calculations that decide string length against the coldest recorded ambient temperature at the site. Article 705.12 sets the interconnection rules, including the 120 percent busbar allowance that determines whether a main service panel upgrade is required. Article 706 covers battery energy storage.
Listing and certification is non-negotiable. Inverters must carry UL 1741 with SA or SB supplements to demonstrate grid support functions, modules need UL 61730 and IEC 61215 certification, and rapid shutdown devices need UL 3741 or equivalent system-level compliance. A component library that includes SKUs without valid US listings will produce designs the utility refuses to energize.
Structural and environmental loading follows ASCE 7, with wind speed, snow load and seismic design category varying by site. Florida high-velocity hurricane zones in Miami-Dade and Broward counties impose their own product approval requirements. If the software cannot export geometry to the structural engineer, that review becomes manual.
String sizing against the inverter voltage window is the calculation most often done wrong in a hurry. If you want to sanity-check a design outside your primary tool, this free string sizing calculator is a fast cross-check, and the NEC 705.12 interconnection explainer covers the busbar rule in detail.
ITC, IRA Adders and Depreciation Inside the Software
The financial layer is where American solar software earns or loses credibility, because the incentive structure has more moving parts than most markets.
The base Investment Tax Credit is 30 percent. Residential systems claim it under Section 25D, where it is non-refundable and carries forward against future federal tax liability rather than arriving as cash. Commercial systems claim it under Section 48E, where it pairs with 5-year MACRS depreciation, the depreciable basis is reduced by half the credit, and the half-year convention applies in year one. On top of the base rate sit adders for domestic content, siting in a designated energy community, and low-income qualification, which can push a qualifying commercial project meaningfully above 30 percent.
State-level revenue then varies enormously. Solar renewable energy certificate markets in New Jersey (SuSI), Massachusetts (SMART), Maryland, Pennsylvania, Illinois and Washington D.C. can contribute 15 to 30 percent of project value where they are strongest. The Solar Energy Industries Association maintains the state-by-state policy reference, and the International Energy Agency provides the global cost benchmarks worth comparing US installed prices against.
The practical test during a software trial is simple: build a $500,000 commercial project in a designated energy community with domestic content modules, and ask the tool to produce a year-by-year after-tax cash flow. Platforms that can only show a flat 30 percent reduction are residential tools regardless of how they market themselves.

Net Metering and Rate Design by State
Export compensation decides savings, and in the USA it is set state by state, sometimes utility by utility.
California’s net billing tariff, in force since April 2023, compensates exports at hourly avoided-cost values instead of the retail rate. That single change moved the design objective from maximizing production to maximizing self-consumption, which is why battery attachment rates in California climbed sharply afterwards. A tool that still applies retail-rate netting to a California address will overstate savings on every proposal it produces.
Other states diverge sharply. Florida retains full retail net metering for residential customers. Texas has no statewide requirement, so buyback terms are set by each retail electric provider and vary from generous to negligible. Arizona uses a periodically reset export rate. Hawaii, with the highest retail electricity prices in the country, runs its own self-supply and grid-supply programs. Commercial accounts add demand charges, which means a peak-shaving analysis matters more than a kilowatt-hour offset calculation. The U.S. Energy Information Administration publishes the retail rate data all of these models rest on.
⚠️ Watch out
Ask every vendor two questions: how often does the utility rate library update, and who maintains it. A stale time-of-use schedule makes every savings figure wrong from the moment it is generated.
What a 5-Person US Installer Should Actually Buy
Layer coverage is theory. Here is the practical stack advice by business type, based on what our own team and our channel partners run.
- Residential installer, single state, 10 to 20 jobs a month. One bundled platform (SurgePV or Aurora) plus inverter-native monitoring. That is one paid license. SurgePV at $6,495 per year for five seats undercuts five Aurora Basic seats at $8,100 and five Premium seats at $13,200, though Aurora Basic at $1,620 per user per year is cheaper than a single SurgePV Individual seat at $1,899.
- Multi-state residential and light commercial. Bundled platform plus outsourced plan sets (GreenLancer) for states where you do not yet know the AHJ requirements, moving in-house once volume in that state justifies it.
- C&I focused EPC. Bundled platform for design, proposals and plan sets, plus HelioScope or PVsyst when a specific lender or independent engineer names a report format, plus AlsoEnergy or an equivalent monitoring platform if you carry performance guarantees.
- Utility-scale developer. PVsyst for the bankable yield report, a design platform for layout and BOM, and monitoring specified in the O&M contract. The sales layer barely applies.
- Sales-heavy organization with subcontracted install. Bundled platform for the engineering plus Sunbase or a solar CRM for pipeline and commission tracking.
The pattern across all five is that the design and proposal layer is the one worth consolidating, and everything else is bought on need. That is the argument for a bundled platform: it is the layer where running two licenses costs you both money and number consistency.
Pros and Cons: Standardizing on SurgePV
The tradeoff, stated plainly.
- ✓ You want four layers on one license
- ✓ You work across states with different export rules
- ✓ You bid commercial where MACRS matters
- ✓ Your current per-seat bill exceeds $150 a month
- ✓ You want plan sets from the sold design
- ✗ Your bank insists on a PVsyst-format report
- ✗ Monitoring a live portfolio is the real problem
- ✗ Crew dispatch, not design, is your bottleneck
- ✗ You are a solo installer at two jobs a month
SurgePV wins this ranking on bundled layer coverage and USD cost, and it loses on monitoring (which it does not do), on US brand tenure against Aurora, and on the specific case where a lender names PVsyst by report format. Those are real gaps rather than marketing caveats, and any vendor that tells you their platform covers all six layers is describing a roadmap.
How Heaven Green Energy Helps
Heaven Green Energy is a solar EPC with 200+ MW installed and a 12-person in-house design team, so we evaluate software as an operator rather than a reviewer. Our test for the best solar software in USA is whether the number that reaches the customer survives the engineer, the lender and the inspector without changing. That test is why bundled design and proposal platforms rank above sales-first tools here, and why we treat monitoring and bankable simulation as separate purchases rather than checkboxes.
- Solar EPC services for turnkey design, supply and installation with performance guarantees.
- Commercial solar for 10 to 100 kW systems with full financial modeling.
- Industrial solar for 100 kW and above with bankable yield reporting.
- Solar calculator for a 60-second sizing and payback estimate.

Frequently Asked Questions
What is the best solar software in USA in 2026?
SurgePV ranks first for most US installers at $1,299 per user per year on the 5-User Team plan, covering design, 8,760-hour simulation, proposals and NEC 2023 plan sets in one license. Aurora Solar is the deepest US-native alternative at $135 per user per month on Basic and $220 on Premium, both billed annually, with a more mature template and utility rate library. Aurora Basic works out cheaper per seat than SurgePV. Neither covers monitoring, and specialist tools such as PVsyst, Scanifly, GreenLancer and AlsoEnergy each own a layer that no all-in-one platform replaces.
How many software tools does a US solar installer actually need?
Most five-person US installers run two or three. A bundled design and proposal platform is the core purchase, since running separate design and proposal licenses costs both money and number consistency. Beyond that, add tools by bottleneck: outsourced plan sets when entering unfamiliar states, a CRM or field operations tool when crew coordination is the constraint, and a monitoring platform when you carry performance guarantees on commercial assets.
How much does solar software cost in the USA?
Published 2026 pricing spans a wide range. Bundled design and proposal platforms run $1,299 to $2,640 per user per year, with SurgePV at $1,299, Aurora Basic at $1,620, Aurora Premium at $2,640 and HelioScope at $1,620 to $2,640. PVsyst bills in Swiss francs at CHF 700 per user per year on an annual subscription. Scanifly does not publish a price. Outsourced permit plan sets from GreenLancer and commercial monitoring from AlsoEnergy are both quote-only, with no rate published by either vendor, so neither can be budgeted from public figures. On the published prices alone, five seats of a bundled design platform run $6,495 to $13,200 per year.
Does US solar software need to handle NEC 2023?
Yes, in over 40 states. NEC 2023 changed rapid shutdown requirements under Article 690.12, maximum voltage and current calculations under 690.7 and 690.8, and interconnection rules under Article 705 including the 120 percent busbar allowance. Software shipping a stale code library produces designs that fail AHJ plan review, which costs a resubmission cycle and often a change order. Ask any vendor which NEC cycles they support and how quickly they track state adoption.
Which solar software do US lenders accept for yield reports?
PVsyst remains the report format most frequently named by US project finance lenders and independent engineers on utility-scale deals. HelioScope is widely accepted for commercial and industrial projects. SurgePV and Aurora both produce 8,760-hour hourly simulations with P50, P75 and P90 outputs suitable for residential and most commercial underwriting. On a large financed project, confirm the required format with the lender before you build the model, not after.
Does any solar software cover monitoring as well as design?
Not credibly, as of 2026. Design platforms including SurgePV and Aurora stop at commissioning. Monitoring is served either by inverter-native platforms (Enphase Enlighten, SolarEdge Monitoring, and comparable string inverter portals) for residential portfolios, or by hardware-agnostic systems such as AlsoEnergy PowerTrack for commercial and utility-scale assets where performance ratio evidence supports warranty and guarantee claims. Budget monitoring as a separate line item.
Is free solar software good enough for a US installer?
For a solo installer doing two or three straightforward residential jobs a month, OpenSolar’s free tier is workable. Beyond that it stops holding. The core platform stays free, which on licence cost beats every paid platform including SurgePV. What changed on 16 April 2026 is that API Access is charged per project on creation and Connectors carry a flat monthly fee, and OpenSolar had not published either rate as of 2 August 2026, so you cannot budget the full setup without asking. Commercial capability is limited and the code library update cadence is not something to rely on for AHJ submissions.
What is the fastest way to compare solar software for a US team?
Run the same real project through every shortlisted tool during trials: one residential address in your busiest state and one commercial site. Compare the P50 yield figures, check whether each tool applies your state’s actual export rule, produce a proposal and a plan set from each, and time the full workflow. Differences in yield of more than three or four percent on identical inputs tell you which simulation engine to trust. Most vendors offer trials, and SurgePV’s requires no credit card.
Stop paying for four tools. Design it all in one.
SurgePV replaces Aurora + HelioScope + PVsyst + a separate proposal tool in a single license. AI 3D roof in under 60 seconds, bankable 8,760-hour simulation, auto-SLD, BOQ, DXF/DWG export and branded proposals.
