Aurora Solar is the most complete solar proposal software in 2026, and it is also the most expensive at $135 to $220 per user per month on annual billing. OpenSolar is still the strongest free option, but note that API access and connectors moved to paid billing on 16 April 2026.
Key Takeaways
- Proposal accuracy is a modeling problem before it is a software problem. The national fleet data supports what installers report: a median performance loss rate of 0.75% per year against the 0.5% per year most tools assume by default, and median annual soiling losses of 2% to 3% that can run as high as 15%. Two tools can model the same roof correctly and still disagree on the twenty-year number.
- The proposal is the start of the job, not the end of it. Residential projects now average 4.5 to 6 months from contract signing to permission to operate.
- If your proposals are accurate and your installs still slip, a better proposal generator is not the fix. We rank the seven proposal platforms below on five criteria, then explain what sits underneath them to drive projects forward.
- Scoop acts as the operational layer to improve install projects post-proposal. It connects to your existing design software with native integrations for Aurora Solar, OpenSolar, HelioScope, Solo and Bodhi, plus Enerflo, SumoQuote, DocuSign and Salesforce on the sales and paperwork side.
What Is the Best Solar Proposal Software?
The best solar proposal software in 2026 is Aurora Solar for teams that want one platform covering 3D design, shading analysis, financing options and a client-ready proposal, and that can absorb a per-user license.Â
- OpenSolar is the best free solar proposal software and remains the right first tool for a small or early-stage installer.
- Solo is the strongest fit for high-volume residential sales organizations that measure everything in time-to-proposal.
- HelioScope is the best solar design software for commercial and industrial work where the engineering model has to hold up to scrutiny, though it does not generate proposals at all.
We rank all seven below against five criteria we apply on real projects, and we publish the price for every entry, including where a vendor does not publish one.
Important note: Proposal software wins you the signature. It does not procure the equipment, schedule the crew, run the site survey punch list, capture the commissioning evidence or handle the service call in year three. That is a separate system, and it is where most of the margin is won or lost.
Scoop is the operations platform installers connect their proposal tool to, so that the signed proposal becomes a scheduled, documented and auditable job, and so new installs, service calls and recurring O&M work all run from one place. This will be covered in more depth following the rankings.
How We Ranked These Tools
Scoop works with hundreds of solar and renewable energy companies, and we see the same proposal tools brought up across conversations. These are the five criteria we use, in the order that matters.Â
- Estimate accuracy, and how honestly the tool handles uncertainty. Not just whether the model is good, but whether you can see and override the derate assumptions that drive it, and whether the tool tells you what it does not know.
- Design depth. 3D modeling, shading and irradiance simulation, battery and storage modeling, commercial layouts, single-line diagrams and CAD export.
- Integration depth and the handoff to operations. What happens to the design, the bill of materials, the signed contract and the customer record the moment the deal closes? Does it flow into procurement, permitting, scheduling, installation and then into service and recurring O&M, or does somebody retype it?
- Customer success and implementation support. Most vendors gate hands-on help behind an enterprise contract. Buyers discover this after they’ve onboarded their projects, which is exactly when it matters. We weigh it heavily because it is the difference between a tool you bought and a tool your team uses.
Criteria We Did Not Include, and Why
Two things a buyer might expect to see scored here are deliberately absent, and it is worth saying why:
- Lead generation and canvassing features. Several of these platforms bundle territory management, door-knocking apps or lead marketplaces. Those are worth having, but they are a sales-channel decision, not a proposal-software decision, and including them would reward bundling over quality of the core product.
- Operations execution. Work order management, crew scheduling, field capture, punch lists, warranty and SLA evidence are a different category with a different buying committee. We score those on our roundup of the best solar software companies instead of penalizing a proposal tool for not being an operations platform.
- Pricing transparency. The chart below offers as much pricing information below as possible, to give a share a starting point for what companies can expect to pay. However, what a vendor publishes speaks more to their marketing strategy than the quality and relevance of the product. A high-quality tool may not offer pricing upfront, but can still be worth learning more about.Â
Solar Proposal Software Compared (2026)
Pricing verified 28 August 2026 from each vendor’s published pricing page. Where a vendor does not publish a price, we say so plainly rather than guessing.

See What Happens After the Proposal Is Signed
If your proposals are strong and your installs still slip, the gap is in the handoff. Bring one of your own projects to a Scoop demo and we will walk through exactly where it stalls between signature and permission to operate.Â
Most teams start with a 20-minute discovery call first so the demo is about your workflow rather than ours. No credit card, no obligation, and we respond the same business day.
1. Aurora Solar: Best Overall Solar Proposal Software

What Aurora Solar does best
Aurora Solar is the most complete single platform in this category, and it is the tool most often named when installers argue about accuracy. It covers remote 3D design, shading and irradiance simulation, storage modeling, financing options and a client-ready proposal without leaving the browser, and it produces permit-ready plan sets on the same design data. For a team that wants one system rather than three, this is the one to beat.
The strength that matters commercially is design accuracy translating into fewer change orders. A design that survives contact with the roof is a job that does not get re-cut, re-quoted and re-scheduled, and change orders are where residential margin quietly disappears.
Pricing
Basic is $159 per user per month month-to-month or $135 per user per month on annual billing. Premium is $259 per user per month month-to-month or $220 per user per month on annual billing. Enterprise is custom-priced per project. Basic and Premium are credit-card only and are limited to 50 projects per month and one user per license. Verified 28 August 2026.
What it’s best for
Residential and light commercial installers doing consistent volume who want design, proposal and permit packages in one place, and who can justify a per-seat license for every designer and closer.
Aurora Solar limitations
Aurora Solar is the most expensive option here on a per-seat basis, and the one-user-per-license model means the cost scales directly with headcount rather than with revenue. Reviewers on Capterra repeatedly report heavy memory use and the absence of autosave, with work lost when an account is signed in from two machines at once. Enterprise pricing is not published, so a growing team cannot model its own next tier.
Verdict
If you can absorb the seat cost, Aurora Solar is the best solar proposal software available in 2026. Connect it to your operations platform on day one through the Aurora integration so the design and the bill of materials land in the job record instead of a PDF folder.
2. OpenSolar: Best Free Solar Proposal Software

What OpenSolar does best
OpenSolar remains the only serious platform in this category whose core workflow is free, including the whole design-to-proposal path rather than a crippled trial. There are no seat limits, no licensing fees and no design caps, which makes it the obvious first tool for a small installer and a genuinely useful second opinion for a large one.
The 3D design capabilities allow for detailed visualizations, which makes system planning easier and more effective, and the built-in financing integrations mean a salesperson can put a payment option in front of a homeowner in the same session.
Pricing
The core platform is free. Since 16 April 2026, API access and connectors are billed separately, and an OpenSolar Wallet must be funded or new project creation stops. The vendor has not published the connector or API rates, so budget for an unknown here if you rely on API-driven data flow. Verified 28 August 2026.
What it’s best for
Early-stage and small residential installers, and any team that wants a no-cost baseline to sanity-check another tool’s numbers.
OpenSolar limitations
Independent reviews consistently note limited control over advanced system parameters, which is the same complaint installers raise about the production estimates: when the model runs conservative, there is not much room to see why or to correct it in a defensible way. It is not intended to carry a detailed engineering validation, and the April 2026 move to paid API access introduces a cost line that did not exist when many teams standardized on it.
Verdict
Still the best free solar proposal software, and still the right starting point for a small team. Verify its production assumptions against a second model before you put a twenty-five year savings number in front of a customer, and route the signed deal onward through the OpenSolar integration.
3. Solo: Best for High-Volume Residential Sales Teams

What Solo does best
Solo is built around one metric: how fast a rep can turn an address into a signed contract. Design, proposal, SoloSign e-signature, financing partners and permit packages sit in one flow, and unlimited users on every plan means a growing sales org is not penalized for hiring. Installers who have used it alongside OpenSolar describe its production numbers as reliable enough to sell on without hand-tuning.
Pricing
Not publicly listed. The vendor describes flexible options based on usage, support level and scale, with unlimited users and concierge onboarding included. Third-party directories list tiered and per-project figures, but those are not vendor-published and we do not treat them as verified. A one-time onboarding fee applies. Verified 28 August 2026.
What it’s best for
High-volume residential sales organizations with a large rep count, where seat-based pricing on another platform would be the constraint.
Solo limitations
No published pricing means no self-service evaluation, and you cannot model your own cost before talking to sales. The month-to-month plan excludes parts of the product, DXF export is a paid add-on, and a separate one-time onboarding fee applies on top of the subscription.
Verdict
The right choice when rep headcount is your scaling constraint rather than design complexity. Ask for the total first-year cost including onboarding in writing, and connect it downstream through the Solo integration so closed deals do not sit in the sales tool.
4. Solargraf: Best for Teams Standardized on Enphase

What Solargraf does best
Solargraf covers design, proposal, e-signature, financing and permit packages, and its real advantage is how tightly it sits inside the Enphase ecosystem. If your equipment decisions are already made and they are Enphase, the data flows with less friction than any general-purpose tool will give you. Project-count pricing rather than seat pricing also suits a team where many people touch a project but few create designs.
Pricing
Starter is $2,799 per year for 240 projects and 2 users. Small Business is $4,799 per year for 480 projects and 4 users. Teams is $6,399 per year for 720 projects and 6 users. Enterprise is $12,999 per year for 1,500 projects and unlimited users. Extra projects run $9 to $11 and extra users $960 to $1,440 depending on tier. A public API is a $4,000 per year add-on. Annual billing only. Verified 28 August 2026.
What it’s best for
Mid-market residential installers with predictable annual project volume and an Enphase-standard equipment stack.
Solargraf limitations
Users report production estimates varying by 10% to 20% against Aurora Solar and HelioScope with no manual override to reconcile them, which is a real problem if you are defending a number to a customer. There is no support for carports, trackers or East-West racking, and annual-only billing with per-project overage means a busy year costs more than the sticker.
Verdict
A strong, well-priced fit for a specific profile: Enphase-standard, residential, predictable volume. If your work includes carports, ground mounts or trackers, look further up this list.
5. Pylon: Best for Small Teams That Want Pay-As-You-Go Pricing

What Pylon does best
Pylon prices by the project rather than by the seat, which changes the economics for a small or seasonal team completely. You buy credits, unlimited users share them, re-editing an existing project costs nothing, and there is no monthly minimum. For an installer doing twenty jobs a month, that is a fundamentally different bill from a per-seat license.
The product itself covers 3D design, shading, proposals, and battery and commercial work on the Pro tier, with an optional CRM and a payment gateway if you want the sales stack in one place.
Pricing
Standard is $4.00 per project and Pro is $10.00 per project, bought in credit packs, with Enterprise custom-priced. The CRM add-on starts at $49 per user per month and the payment gateway takes 2.50% per transaction. Five Standard project credits are free with no credit card required. Verified 28 August 2026.
What it’s best for
Small installers, seasonal operators and teams where project volume swings month to month.
Pylon limitations
Reviewers report inconsistency in the aerial imagery integration and proposal layouts shifting when exported to PDF, which matters when the PDF is the thing the homeowner keeps. The vendor originates outside the United States and its pricing page references GST, so confirm the billing currency in writing before you commit.
Verdict
The best value on this list for a low-volume or variable-volume team. Confirm the currency, and test a real proposal export before you standardize on it.
6. HelioScope: Best Solar Design Software for Commercial Projects

What HelioScope does best
HelioScope is a highly specialized simulation tool. Irradiance and shading simulation, LiDAR-assisted obstruction detection on the Pro tier, single-line diagrams and CAD or DXF export give you a model an engineer will sign off on and a file a permitting body will accept. When installers debate which platform is the most accurate for commercial work, this is the one that comes up alongside PVsyst.
Pricing
Basic is $159 per month or $1,620 per year per license, covering 10 projects per month or 120 per year. Pro is $259 per month or $2,640 per year. Enterprise is custom-priced. One user per license. Verified 28 August 2026.
What it’s best for
Commercial and industrial designers and engineering teams who need the model to withstand third-party review.
HelioScope limitations
HelioScope does not generate proposals, has no e-signature and no CRM, so it cannot be your only tool if you also sell. There is no native battery or hybrid modeling and a 15 MW project cap, which puts utility-scale work out of reach. Treat it as the engineering half of a two-tool stack.
Verdict
Buy it as the design and validation layer, pair it with a proposal tool for the customer-facing half, and connect both downstream through the HelioScope integration.Â
7. Scanifly: Best for As-Built Accuracy on Complex Roofs

What Scanifly does best
Scanifly starts from a drone flight rather than a satellite image, and builds the 3D model from photogrammetry captured on site. On a complex roof, a heavily shaded lot or an older structure where the aerial imagery is stale, that is the difference between a design that installs and a design that gets redrawn on the truck.Â
Pricing
Basic is $75 per month and Professional is $220 per month, both billed annually. Design and plan-set services are billed in credits: 15 credits for a residential site model, 70 for a residential plan set, 100 for a commercial site model, with commercial plan sets custom. The vendor does not publish a dollar value per credit. Verified 28 August 2026.
What it’s best for
Installers whose rework is concentrated in site conditions rather than in modeling, and teams already flying drones for site surveys.
Scanifly limitations
Scanifly requires a commercial drone and an FAA Part 107 licensed pilot at every property, which is a real operational cost and a hiring constraint. There is no single-line diagram generation, no financial modeling, no CRM and no proposal tool. It is a capture and design layer rather than a sales platform. Accurate site capture also does not guarantee an accurate production estimate: the irradiance model on top of the geometry still has to be right.
Verdict
Add it when site-condition rework is costing you more than the drone program would. Do not buy it expecting it to solve a production-estimate dispute, because that is a different problem.
Softwares We Also Evaluated
Four more platforms came up during this review and did not make the seven, for reasons worth stating.Â
- Enerflo is a solid sales and proposal platform with a flat monthly rate by volume, but it publishes no figures at all and requires a twelve-month minimum plus a one-time implementation fee.
- Arka 360 lists $199 to $358 per month in the United States with strong AI-assisted design, but reviewers describe a steep learning curve and a large jump to Enterprise for small teams.
- Sunbase starts at $59 per user per month and is primarily a CRM with design attached rather than a design tool with CRM attached.
- Solesca is a capable pre-CAD engineering tool that added a stampable single-line diagram workflow in May 2026, but it publishes no pricing and has no proposal, e-signature or financing layer.
What Proposal Software Does Not Cover
Every platform above ends at the same place: a signed contract and a project PDF. What happens next is the part that decides whether the job is profitable.
Look at where the time actually goes. Residential projects average 4.5 to 6 months from contract signing to permission to operate, and the design phase is 20 business days of that. The rest is procurement, permitting, scheduling, installation, inspection and interconnection. Â
Scoop is the solar project management platform that runs that half. It takes the signed proposal, the design, the bill of materials and the customer record, and turns them into a scheduled job with the right workflow attached: site survey, procurement, permitting, install checklist, commissioning evidence, customer sign-off, and then the service history that follows for the next twenty years.
Who Scoop is best for
High-volume residential installers. When you are running dozens of jobs a week, the failure mode is not a bad design, it is a job that sat for nine days because nobody knew it was waiting on a permit.
Sunlight Solar reached 500% operational growth on that principle. Â
O&M providers with recurring service contracts. This is the segment proposal software never touches, and it is now the segment with the most predictable revenue. Recurring work orders, preventive maintenance schedules, warranty claims, SLA evidence and full asset history all live in the same system as the original install, so the technician arriving in year seven can see how the array was built, who commissioned it, what was replaced and what the contract obliges you to prove.Â
Renewable energy companies managing partner-led project delivery. When subcontractors and partners execute the work, the audit trail is the product.
Youdera and NEC Solar both use Scoop to centralize operations across complex installs.
The Accuracy Problem Across Proposal Tools
Ask installers which proposal tool is most accurate and the conversation goes somewhere more interesting than a feature comparison. The complaints are consistent and they are worth taking seriously, because they change how you should evaluate any of the seven platforms above.
Production Estimates Drift, in Both Directions
The most common report is a system in production generating 15% to 20% more than the tool estimated, which sounds like good news until a customer asks why the proposal understated it, or until a competitor’s more aggressive estimate wins the deal. Teams compensate by manually adjusting assumptions, typically in the 4% to 8% range, which means the number you are selling reflects somebody’s judgment call rather than the model.
The practical rule experienced designers apply: bad inputs produce bad outputs regardless of the platform. Before you blame the software, check the derate stack, and check whether anyone on the team ever changed it from the defaults.
Design Accuracy and Production Accuracy Are Different Problems
A drone-captured photogrammetry model gives you the most accurate geometry available, and installers still report that the production estimates on top of it can be off. Accurate roof capture and accurate energy modeling are two separate layers, and buying a better camera does not fix the irradiance math. When you evaluate a tool, test them separately: does the model match the roof, and does the yield match systems you already have in the ground?
A Tool Can Be Excellent at One Half and Poor at the Other
Installers describe platforms where the tariff and rate modeling is meticulous, letting them true up every last rate detail across markets where net metering rules change within a few miles, and where the design experience is then a serious step down. The reverse also happens. Rate accuracy matters as much as design accuracy for the number on the proposal, and very few tools are strong at both, which is a large part of why stacks exist.
How to Test This Before You Buy
Take three systems you already have in production with at least a year of monitoring data. Model all three in every tool on your shortlist, using the same equipment and the same assumptions, and compare the estimates against actual generation. It takes an afternoon and it will tell you more than any feature matrix, including this one. Then check whether the tool lets you see and change the derate assumptions that produced the difference.
Which Solar Proposal Software Should You Choose?
Our recommendation by segment, with the operations layer named alongside the proposal tool, because in practice you are buying a pair:
- Five-person residential installer, budget is limited: OpenSolar for proposals. Add Scoop once you are running enough concurrent jobs that a whiteboard stops working, which is usually somewhere around fifteen.
- High-volume residential sales organization: Solo for proposals, because unlimited users removes the seat-cost ceiling. Scoop underneath it so the closed deal becomes a scheduled job the same day.
- Mid-market residential installer on Enphase equipment: Solargraf, with the caveat about production variance above. Verify its numbers against a second model before you standardize.
- Commercial and industrial EPC: HelioScope for the engineering model, Aurora Solar or Solo for the customer-facing proposal, and Scoop for multi-site execution and the audit trail your client will ask for.
- O&M provider with recurring service contracts: none of the proposal tools serve you well, because your revenue starts after the install. Go straight to a solar O&M platform with preventive maintenance scheduling, SLA-ready audit trails, full asset history and truck-roll reduction as the primary measures.
- Multi-state operator: Aurora Solar for the breadth of permit and jurisdiction coverage, and an operations platform that can hold a different workflow per state without becoming a different system per state.
How to Choose Solar Proposal Software
Most evaluations get decided on the demo, which is the worst possible moment to decide. These are the questions worth asking on a trial, in roughly this order:
- Model three of my own in-production systems. How close are the estimates to actual generation, and can I see and change the derate assumptions that produced them?
- What is the true first-year cost including onboarding, implementation, API access, connectors, overage and any add-on my workflow requires?
- When the deal closes, where does the design, the bill of materials and the customer record go, and who retypes it?
- What happens to my pricing when I add five people, or double project volume in a good quarter?
- Who helps me configure this in month two, and is that person included or is it an enterprise line item?
- Does the tool handle the work I actually sell, including batteries, carports, ground mounts and commercial layouts, or only the easy residential case?
Stop Paying for Tools That Do Not Talk to Each Other
You can buy the best solar proposal software on this list and still lose the margin between signature and permission to operate. That gap is where the retyping, the missed permit deadlines, the second truck roll and the customer chasing an update all live, and no proposal tool is built to close it.
Bring one of your own projects to a demo and we will map where it actually stalls, then show you what the same job looks like when the proposal tool, your solar CRM and the field team are on one thread. Most teams start with a 20-minute discovery call first so the demo is about your workflow. No credit card, no obligation, and we respond the same business day.
Frequently Asked Questions About Best Solar Design Software
What is the best free solar proposal software?
OpenSolar is the best free solar proposal software. Its core platform is free with no seat limits, licensing fees or design caps, and it includes 3D design, shading analysis, proposal generation and financing integrations. Note that since 16 April 2026 API access and connectors are billed separately, so teams relying on API-driven data flow should confirm those rates before standardizing on it.
What is the best solar design software?
For commercial and industrial work, HelioScope is the best solar design software, offering irradiance and shading simulation, LiDAR obstruction detection, single-line diagrams and CAD export from $1,620 per year. For residential design bundled with a proposal, Aurora Solar is the stronger choice. For complex or heavily shaded roofs where remote imagery is unreliable, Scanifly’s drone photogrammetry produces the most accurate site geometry, though it requires an FAA Part 107 licensed pilot.
How accurate is solar proposal software?
Accuracy depends more on the assumptions than on the platform. Installers routinely report in-production systems generating 15% to 20% above or below the estimate, and the national fleet data shows why the inputs are uncertain: a median performance loss rate of 0.75% per year against the 0.5% commonly assumed, and median annual soiling losses of 2% to 3% ranging as high as 15%. Before comparing tools, model three of your own in-production systems in each one and compare against actual generation.
Why do my solar production estimates differ from actual output?
In most cases the derate assumptions are wrong for your market rather than the tool being broken. Soiling, degradation rate, inverter availability and shading inputs are usually left at platform defaults that were never tuned for your climate or your equipment. Check the derate stack first, confirm that the shading model matches the actual obstructions, and only then compare platforms. Some tools give you limited control over these parameters, which is itself a reason to choose one over another.
Do I need a drone to get accurate solar designs?
Not usually. Remote design from aerial imagery is sufficient for most straightforward residential roofs. A drone workflow earns its cost when your rework is concentrated in site conditions: complex or multi-plane roofs, heavy shading, older structures, or markets where the available aerial imagery is out of date. It requires a commercial drone and an FAA Part 107 licensed pilot at every property, so treat it as an operational program rather than a software purchase.
How much does solar proposal software cost in 2026?
Published prices range from free to roughly $2,640 per user per year. Aurora Solar runs $135 to $220 per user per month on annual billing. HelioScope is $1,620 to $2,640 per year per license. Solargraf is $2,799 to $12,999 per year by project volume. Pylon charges $4.00 to $10.00 per project. Scanifly is $75 to $220 per month billed annually. OpenSolar’s core platform is free. Solo, Enerflo and Solesca do not publish pricing. All figures verified 28 August 2026 from vendor pricing pages.
What is the best solar software for O&M and recurring service work?
Proposal software does not cover O&M at all, so this is a separate purchase. What you need is recurring work order scheduling, preventive maintenance plans, warranty and SLA evidence, full asset history and a field app that works without signal. Â
Should proposal software and project management software be the same tool?
In our experience, no. The all-in-one platforms tend to be excellent at one half and adequate at the other, and installers regularly describe tools with meticulous rate modeling and a weak design experience, or the reverse. The stronger pattern is a best-of-breed proposal tool connected to a purpose-built operations platform, with the integration doing the work that a person would otherwise do by retyping. Â
Does Scoop replace my solar proposal software?
No. Scoop does not design PV systems, run shading simulations or generate proposals. It connects to the tools that do, with native integrations for Aurora Solar, OpenSolar, HelioScope, Solo and Bodhi, and takes over at the point the proposal is signed.
Disclosure
Scoop is a solar operations platform, and this article recommends it. We have kept it out of the ranked list because Scoop does not generate proposals and it would be inaccurate to score it as though it did. The rankings and criteria are our editorial opinion, formed from working with hundreds of solar and renewable energy companies, and reasonable people will weight the criteria differently. Competitor pricing was verified on 28 August 2026 from each vendor’s own published pricing page, and where a vendor does not publish pricing we say so rather than estimating.
