Solargraf Alternatives in 2026: 6 Tools That Add Engineering Depth

A US or Canadian residential installer running between 4 and 18 systems a week typically lands on Solargraf for one reason. The proposal layer is genuinely polished. The financing module covers loan, lease, and PPA cleanly. The lead-capture forms feed the rep pipeline without friction. The trouble starts somewhere around month nine. The team takes the first 250 kW commercial inquiry, the shading engine cannot handle the multi-array carport, the PE asks for a stamp-ready NEC 2023 single-line diagram and the cloud export turns out to be a polished schematic rather than an SLD. By the second commercial inquiry of the year, the installer is running Solargraf for proposals and a second tool for engineering, which doubles the per-seat cost of the design layer. A Solargraf alternative that bundles the proposal motion with the engineering depth becomes a margin decision.

Direct answer. The best Solargraf alternatives in 2026 are SurgePV (best all-in-one design plus proposal at $1,299 to $1,899 per user per year), Aurora Solar (best residential close motion at a higher per-seat price), OpenSolar (best free sticker under 50 systems per year), and Pylon (best for solo installers on tight cash). SurgePV is the only platform that pairs the Solargraf-grade proposal motion with 8,760-hour module-level simulation, NEC 2023 single-line diagrams, and AutoCAD DXF export in one license.

This guide is written for the residential or small-commercial installer whose proposal motion is already strong on Solargraf and whose binding constraint sits on the engineering depth side. The voice we are speaking to is Mike in our internal vocabulary: a US or Canadian owner-operator running 5 to 15 systems per week who is paying for two tools and wondering if one license could cover both. We will name what Solargraf still wins on, what it loses on, and the four jobs an installer past 100 systems per year actually needs.

Why Installers Are Shopping a Solargraf Alternative in 2026

Solargraf held a strong proposal-tool position from 2018 through 2023. Three pressures shifted the market in 2024 and 2025. The all-in-one platforms (SurgePV, Aurora) closed the proposal-quality gap, which removed the case for a standalone proposal subscription. The first 200 kW commercial inquiry started showing up in residential installer pipelines faster than the engineering-depth gap could be backfilled. And the Enphase acquisition of Solargraf in 2022 shifted the product roadmap toward Enphase hardware integrations rather than installer-neutral engineering depth.

The engineering depth gap above 100 kW

Solargraf’s shading engine is hour-banded rather than 8,760-hour module-level. The multi-array UI handles the residential job well and breaks on a 250 kW commercial rooftop with mixed roof faces. The SLD output is a polished schematic rather than a stamp-ready NEC 2023 single-line diagram. According to SEIA’s installer market data, the average residential installer running over 100 systems per year now takes 18 to 26 commercial inquiries annually. Solargraf does not scale into that book without a second tool.

The all-in-one platforms closed the proposal gap

SurgePV and Aurora both ship Solargraf-grade interactive web proposals, e-signature, and financing modules. The proposal motion is no longer a differentiator that justifies a standalone Solargraf subscription. The installer running two tools is now paying for a feature both platforms already include.

Per-seat pricing on growing teams

Solargraf publishes per-seat pricing around $129 per user per month, which works out to roughly $1,548 per year per seat. A four-rep residential office pays $6,192 per year on Solargraf alone, before the design tool the team also pays for. The combined Solargraf-plus-design stack typically lands between $9,000 and $13,000 per year for a residential office, which exceeds the SurgePV all-in number.

The CRM-style features that are not a CRM

Solargraf ships lead-capture forms and a basic pipeline view that look like CRM features. Teams using them as a CRM hit the same wall every installer hits with proposal-tool CRMs: no rep performance reporting, no lead routing logic, no pipeline forecasting. The fix is a proper CRM (QuickEstimate, HubSpot, Salesforce) alongside.

What a Solargraf Alternative Has to Do

The Proposal-Plus-Design 4 names the four jobs that determine whether the new platform actually replaces the Solargraf-plus-design stack in one license. The framework focuses on the engineering depth gaps that drive the cutover.

A platform that ships three of four leaves the team running two licenses. The pricing math in the comparison section assumes the team adds the missing tool when needed.

The 6 Best Solargraf Alternatives in 2026

This table ranks the six platforms against the Proposal-Plus-Design 4, the per-seat cost, and the segment fit a residential or small-commercial installer actually needs.

Platform	Plus-Design 4	Starting price	Interactive proposal	8,760-hr shading	NEC SLD	Best for
SurgePV	4 / 4	$1,299 / user / yr	✓	✓	✓	All-in-one design plus proposal
Aurora Solar (with Sales Mode)	4 / 4	$159–$259 / user / mo	✓	✓ (top tier)	✓	High-volume residential
OpenSolar	3 / 4	Free + transaction fees	✓	✗	✗	Solo installers under 50 systems / yr
Pylon	3 / 4	$59 / user / mo	✓	✗	✓ (limited)	Solo installers, low cash
Enact Solar	3 / 4	~$99 / user / mo	✓	✗	✗	India residential PM Suryaghar
HelioScope + custom proposal	4 / 4	$99–$300 / user / mo + custom	✗ (standalone)	✓	✓	C&I bankability above 250 kW

1. SurgePV. The All-in-One Replacement

SurgePV ships the Solargraf-grade proposal motion the team is used to (interactive web URL, e-signature, loan-lease-PPA-cash side by side, full white-label) plus the 8,760-hour shading, NEC 2023 stamp-ready SLD, AutoCAD DXF export, and AI 3D roof modeling that Solargraf does not. The financing module is hardware-neutral by default. The platform is built by the engineering team behind Heaven Designs.

SurgePV pricing is $1,899 per user per year on the individual tier, $1,499 on the three-user team plan, and $1,299 on the five-user team plan. The five-seat team tier at $6,495 per year replaces both a four-seat Solargraf license ($6,192) and the design tool the team also pays for. Book a SurgePV demo to see the design-to-proposal motion on a real address. The companion solar proposal software guide covers the proposal layer in depth.

Verdict. SurgePV is the right call for any residential or small-commercial installer running 50 to 600 systems per year who is currently paying for Solargraf plus a design tool. Skip it only if the team is exclusively Enphase hardware and the Solargraf-Enphase integration depth on IQ Battery dispatch is a meaningful product differentiator on the close.

2. Aurora Solar with Sales Mode

Best for: High-volume residential teams running 200+ installs per year where Aurora Sales Mode is worth the per-seat price.

Strengths: The residential close motion benchmark. Strong satellite-to-permit speed. Mature AHJ rule library. The Aurora Solar alternatives guide covers the broader picture.

Weaknesses: Per-seat $159 to $259 per month. Sales Mode is an add-on. C&I above 1 MW is not the audience.

SurgePV vs Aurora: SurgePV ships the same residential close motion at one-quarter the per-seat cost, with C&I depth Aurora reserves for the top tier.

3. OpenSolar

Best for: Solo installers under 50 systems per year on the free sticker.

Strengths: No upfront cost. Strong proposal builder. Decent satellite roof trace.

Weaknesses: Transaction fees on financed deals compound past 100 systems per year. Engineering depth is shallow. See the OpenSolar alternatives guide.

SurgePV vs OpenSolar: SurgePV wins for any team above 100 systems per year where the transaction fees compound past the SurgePV license cost.

4. Pylon

Best for: Solo installers in India, Indonesia, and the Philippines on tight per-seat budgets.

Strengths: $59 per month per seat. Polished residential layout. Fast onboarding.

Weaknesses: Shading engine is basic. NEC SLD limited. Does not scale into C&I above 100 kW.

SurgePV vs Pylon: SurgePV wins the moment the team crosses 10 systems per week or takes a commercial inquiry.

5. Enact Solar

Best for: India residential installers handling PM Suryaghar volume.

Strengths: India-specific module library. PM Suryaghar subsidy auto-calc. Decent residential proposal.

Weaknesses: US AHJ workflow is thin. C&I depth is shallow.

SurgePV vs Enact: SurgePV wins outside the India-residential PM Suryaghar volume play.

6. HelioScope with custom proposal

Best for: C&I installers above 250 kW where bankable engineering is mandatory and the proposal motion is acceptable as a custom deck.

Strengths: Bankable 8,760-hour simulation. Strong wire-loss model. The HelioScope alternatives guide covers the C&I angle.

Weaknesses: No interactive proposal. The custom proposal motion absorbs designer time.

SurgePV vs HelioScope: SurgePV ships the same 8,760-hour engine plus the proposal layer HelioScope leaves to a second tool.

Pricing Comparison: Solargraf vs the Field

The published list price is one thing. The all-in cost across a year, including the design tool the proposal-only platforms need bolted on, is the number that matters. The table below assumes a four-rep residential office doing 220 systems per year.

Stack	Annual cost (4 seats)	Bolt-on design tool	Plus-Design 4
Solargraf + HelioScope	$6,192 + $9,552 = $15,744	HelioScope for engineering	4 / 4
Solargraf + Aurora Essentials	$6,192 + $7,632 = $13,824	Aurora for engineering	4 / 4
Solargraf alone	$6,192	Manual cleanup in AutoCAD	2 / 4
SurgePV 5-Team	$6,495 (5 seats)	None	4 / 4
Aurora Grow + Sales Mode	$19,068 to $24,840	None	4 / 4
OpenSolar (free)	$42,000+ on financed share	None	3 / 4

The pricing math is consistent with the data NREL’s 2024 US PV cost benchmark reports on residential soft cost. Installers who consolidate from Solargraf plus a design tool to one license recover roughly 5 to 9 cents per watt in soft cost within twelve months. On a 220-system residential book at an average system size of 8 kW, that is between $88,000 and $158,000 per year on top of the direct license savings.

How to Switch from Solargraf to Your New Stack

The migration plays out across roughly four weeks if the team commits to a clean cutover. The fastest path follows five steps.

1. Audit the active Solargraf pipeline. Export every proposal currently in the quoted or signed stage. Categorize by funnel: lead, quoted, signed, permitted, installed. Anything signed or beyond stays in Solargraf until the deal closes.
2. Migrate brand assets and financing presets. Logo, colors, fonts, and the lender presets move to the new platform on the first onboarding call.
3. Rebuild three template proposals in week one. Cover the 80 percent of common quote types: standard residential, residential with battery, light commercial. The team uses these as the starting point on every new lead.
4. Re-train the reps on the new proposal builder. Three to five days of guided practice. The customer-facing URL looks different on the first proposal, so block calendar time before the first live send.
5. Hard cutover for new leads. From day eight, every new lead enters the new platform. The Solargraf account stays open for one quarter to close active deals, then closes at the end of quarter one.

When Staying on Solargraf Is the Right Call

The honest answer is that not every installer needs to leave Solargraf. Three profiles get better economics by staying.

1. Pure-Enphase shops with deep IQ Battery dispatch needs. The Solargraf-Enphase integration still has the deepest IQ Battery dispatch logic. Pure-Enphase shops that win deals on the dispatch story stay on the current platform.
2. Teams under 50 systems per year. The Solargraf-alone sticker is the right call if the team will not cross the 200 kW commercial threshold this year. The engineering depth gap does not earn its keep yet.
3. Mid-renewal teams in the last 90 days of a contract. A mid-renewal cutover absorbs training time the team cannot spare during peak season. Wait for the renewal window.

The signal to switch is a 200 kW C&I inquiry that the team wants to close, a per-seat budget compressing the design-tool spend, or a first PE rejection on a Solargraf-exported SLD.

How Heaven Designs Helps

The switch from Solargraf to SurgePV solves the proposal and design jobs in one workspace. It does not solve the bottleneck most installers hit on the back end of the funnel: a designer who can produce stamped, AHJ-ready permit packets at the pace the proposal is closing. That is where the Heaven Designs bench comes in.

• Solar Permit Design. PE-stamped plan sets in 4 to 7 business days across 38 US states, NEC 2023 compliant, 96.2 percent first-pass AHJ approval.
• Solar Rooftop Detailed Engineering Design. Full IFC pack including GA, SLD, structural, BOQ, and mounting drawings.
• Solar 3D Pre-Design. Sales-stage 3D and shading model delivered in 48 hours.
• Download a sample permit packet. A redacted Riverside County residential install pack.

For the rep pipeline and performance tracking that sits behind the proposal layer, the QuickEstimate solar CRM pairs with SurgePV through a Zapier connector. The CRM handles lead lifecycle and the proposal handles the close motion, which separates the two layers cleanly. For a working quote, contact us. Turnaround is under four business hours.

FAQ

Is SurgePV cheaper than Solargraf?

Yes on the all-in stack. SurgePV’s five-user team tier is $6,495 per year for five seats. A four-seat Solargraf license alone runs roughly $6,192 per year, and the team typically pays another $6,000 to $9,000 per year for the design tool that ships the 8,760-hour shading and the NEC SLD Solargraf does not. The combined Solargraf-plus-design stack typically lands $7,000 to $9,000 per year above the SurgePV one-license number.

Does SurgePV match Solargraf’s proposal quality?

Yes. SurgePV’s solar proposal builder ships a shareable URL proposal with e-signature, loan-lease-PPA-cash side by side, financing module, and full white-label brand control. The motion maps one-to-one to the Solargraf flow. Reps need three to five days of retraining on the new proposal builder before the muscle memory clicks.

Can I migrate my Solargraf proposal templates to SurgePV?

Brand assets and financing-template inputs migrate cleanly on the first onboarding call. The proposal template library itself does not migrate one-to-one because the formats are proprietary. The practical approach is to rebuild three template proposals in week one of onboarding, which covers roughly 80 percent of the typical residential and small-commercial use cases.

Does SurgePV handle Enphase IQ Battery dispatch as well as Solargraf?

For standard IQ8 microinverter and IQ Battery sizing, yes. The Solargraf-Enphase integration still has a slight edge on the most complex IQ Battery dispatch scenarios involving multiple time-of-use schedules. For pure-Enphase shops where IQ Battery dispatch is the close lever on every quote, the Solargraf integration may still earn its keep. For mixed-hardware teams, the SurgePV hardware-neutral approach wins.

Does SurgePV cover the 250 kW C&I rooftop Solargraf cannot?

Yes. SurgePV’s commercial solar design workspace handles C&I rooftop projects up to 5 MW with 8,760-hour module-level shading, NEC 2023 stamp-ready SLD, and AutoCAD DXF export. The same license the residential pod uses covers the commercial book, which removes the second-tool problem the moment the first commercial inquiry walks in.

Will my plan sets still pass AHJ review?

Yes, provided the design follows NEC 2023, the local AHJ checklist, and the structural standard for the state. SurgePV’s auto-generated SLD includes NEC 690.12 rapid-shutdown labeling and the standard residential service entry markings. For PE-stamped permit packets, Heaven Designs delivers the stamped output on the SurgePV design and tracks first-pass AHJ approval at 96.2 percent across 38 US states.

Should I keep Solargraf for the lead-capture forms?

Probably not. The lead-capture forms inside Solargraf are basic compared to a purpose-built CRM. Most teams that switch off Solargraf move the lead-capture motion to QuickEstimate or HubSpot, which integrates with SurgePV through Zapier. The combined CRM-plus-design-plus-proposal stack is more capable than the Solargraf-only motion and typically lands at a similar all-in cost.

Does SurgePV offer a free trial?

Yes. The trial does not require a credit card and runs long enough to design two to three real projects from address to proposal. The recommended path is to bring three live leads from the current Solargraf pipeline to the trial and re-quote each on SurgePV. The proposal-quality and engineering-depth comparison lands on real data rather than a slide deck.
