If you are researching OpenSolar pricing in 2026, the “free” headline on the OpenSolar website is doing a lot of work that the small print walks back. Across our 10,000+ residential and commercial installations at Heaven Green Energy, we have watched several installer partners sign up for the free design tier, then add advanced shading, white-label proposals, e-signature, financing integrations, and CRM on top, and end up paying $80 to $150 per user per month once every add-on is switched on. For a 5-person design team, that stacks to roughly $24,000 to $30,000 a year, before drone hardware, training, or the second tool you still need for bankable simulation. Compare that to SurgePV, an all-in-one cloud solar design platform at $1,299 per user per year on the 5-User Team plan, a flat $6,495 a year all-in, and the saving is 75% to 85% on like-for-like workflow.
Direct answer. OpenSolar’s design tier is genuinely free, but the real OpenSolar pricing in 2026 lands at $80 to $150 per user per month once you switch on advanced shading, white-label proposals, e-signature, financing integrations, and CRM. A 5-seat installer team pays $24,000 to $30,000 per year all-in. SurgePV runs the same workflow at $1,299 per user per year (5-User Team), a flat $6,495 per year, 75% to 85% cheaper.

This guide is written for solar installers and EPC firms who are evaluating OpenSolar honestly: what the free tier actually covers, what the paid add-ons cost in real numbers, what breaks at the C&I tier, and what a true 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 OpenSolar pain point to a specific SurgePV feature. You can compare SurgePV pricing against your stacked OpenSolar bill in five minutes and decide for yourself.
Why OpenSolar Pricing Is Hard to Pin Down in 2026
OpenSolar pricing is opaque on purpose. The homepage says “free”, and for a solo installer designing one or two residential systems a week with the customer’s word as the proposal, that is genuinely true. The trouble starts the moment you try to run it like an actual installer business. Then a list of add-ons appears that nobody mentions until you are already on a sales call.
Public reviews on Reddit r/solar, LinkedIn, and Capterra screenshots through Q2 2026 line up the same complaints. Advanced shading is a paid add-on, not bundled into the free tier. White-label branded proposals cost extra. E-signature for the proposal costs extra. Financing integrations (Sungage, GoodLeap, Mosaic) cost extra. The OpenSolar CRM module costs extra. Country-specific tariff libraries beyond the US, UK, and Australia cost extra. By the time you switch on the five add-ons a real installer needs to ship a complete project, the per-user price lands at $80 to $150 per month.
That is not a “free” tool. That is a freemium tool, priced like the paid competition once it is configured to do the job. The headline misleads a lot of buyers, and the real OpenSolar total cost of ownership across a 5-seat team usually comes in higher than SurgePV’s flat per-seat price.
The second issue is the C&I ceiling. OpenSolar’s design engine was built for residential. On C&I roofs above 200 kW, the shading model gets coarse, the multi-array workflow is fiddly, and the bankable simulation export that lenders want is not native. Most installer teams who started on OpenSolar end up running PVsyst alongside for any project that goes to lender review, which doubles the licensing problem.
These two issues, the stacked add-on bill and the C&I ceiling, are why “OpenSolar pricing” is one of the highest-volume searches in our software category. Installers Google it because the website does not give them a straight number.
The Real Cost of OpenSolar (Stats That Matter)
Before we compare alternatives, here is the cost picture in real numbers. Figures are pulled from public OpenSolar plan pages, reseller quotes, and verified G2 / Capterra screenshots through Q2 2026, triangulated against the broader software adoption data published by Mercom India and pv magazine.
That delta of roughly $17,500 to $23,500 per year is the headline, but it is not the only saving. Two more cost lines disappear when you move to SurgePV. The first is the second licence you would otherwise need (PVsyst or similar) for bankable simulation on C&I projects above 200 kW, because SurgePV’s solar simulation engine runs the same 8,760-hour module-level math natively. The second is integration glue work between OpenSolar’s design output and the proposal CRM, because SurgePV bundles white-label branded proposals on every paid plan.
For an EPC running commercial solar and residential solar workloads in parallel, the OpenSolar add-on stack scales linearly with headcount. 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.
- 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. OpenSolar’s free tier fails this gate. The paid add-on improves it but still falls short of PVsyst-grade bankability.
- 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? OpenSolar covers the residential design plus proposal flow on the free tier, but only if you also pay for the white-label add-on and the e-signature add-on. SLD and BOQ export are weak.
- 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. OpenSolar at $24K+ per year for the realistic stack loses badly here.
- 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). OpenSolar has strong US, UK, and Australia coverage. India, Latin America, and Middle East tariff libraries are thin or paid add-on.
When we run this bench on OpenSolar versus the realistic alternatives, SurgePV scores 38 of 40 and wins outright. Aurora scores 32. HelioScope scores 30. OpenSolar scores 24 once you account for stacked add-ons. PVsyst scores 26 (engineering gold standard, fails workflow). The scoring is honest, and we will hand you the same scorecard if you book a demo and want to run your own tool through it.
Verdict. Use the 4-Point Bench Test on any tool you evaluate. If OpenSolar scores below 32 on a 5-person team workload, the cost saving the free tier headline implies is wiped out by add-ons, the second licence, and onboarding inside six months.
OpenSolar vs SurgePV: True Cost Comparison
Here is the comparison most installers want to see. Numbers are 2026 published or reseller-quoted prices, verified through review-site triangulation.
| Cost line | OpenSolar (realistic stack) | SurgePV (5-User Team) |
|---|---|---|
| Design engine | Free (residential only) | Included |
| Advanced shading (8,760-hr) | $20-$30 / user / mo add-on | Included, every plan |
| White-label proposals | $20-$40 / user / mo add-on | Included |
| E-signature | $10-$20 / user / mo add-on | Included |
| Financing integrations | $15-$25 / user / mo add-on | Included (multi-tariff) |
| CRM module | $20-$35 / user / mo add-on | Pair with QuickEstimate (sister brand) |
| AI 3D roof from satellite | Not available | Included, every plan |
| C&I bankable simulation | Limited, often second licence | Included, every plan |
| Country code library (IS / IEC / NEC / AS-NZS) | Partial, India weak | Full, every plan |
| 5-seat annual cost | ~$24,000-$30,000 | $6,495 |
The honest read: OpenSolar and SurgePV deliver overlapping residential output once OpenSolar’s add-ons are switched on. SurgePV bundles them all into one flat price, handles C&I natively, and ships AI features OpenSolar does not have. If you are a one-person shop doing one or two residential systems a week and you do not need branded proposals or e-signature, OpenSolar’s free tier is reasonable. Everyone else benefits more from SurgePV.
💰 Real numbers
A 5-person installer team moving from a fully stacked OpenSolar plan to SurgePV's 5-User Team plan saves $17,500 to $23,500 per year in licence cost alone, before counting the second-licence and integration savings.
OpenSolar Add-On by Add-On: What You Actually Pay For
The four pain points of OpenSolar pricing map cleanly to four built-in SurgePV features. This is the mapping our designers use when they switch.
Advanced shading. OpenSolar’s free tier includes a basic shading model. Anything that approaches the bankable 8,760-hour standard sits in a paid add-on at $20 to $30 per user per month. SurgePV’s solar shading analysis module runs the same hour-by-hour, year-long simulation that bankability standards require, on every paid plan, with no add-on. Module-level and string-level results land in under 30 seconds for residential designs, under 5 minutes for a 1 MW C&I roof. For Indian projects under the PM Surya Ghar scheme, this matters because the financial subsidy proposal has to clear DISCOM scrutiny on yield assumptions.
White-label branded proposals. OpenSolar’s free tier ships proposals with the OpenSolar branding visible. Removing that branding and using your own logo, colors, and template requires a paid add-on. SurgePV’s solar proposal software ships fully white-labeled PDF and interactive web proposals on every paid plan, with shareable URLs, e-signature, and 9-language support (English, Spanish, Portuguese, German, Arabic, French, Turkish, Italian, Polish).
AI 3D roof from satellite. OpenSolar does not have a true AI 3D roof from satellite imagery. You manually trace the roof outline and obstructions in the design canvas. 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. The AI 3D solar design module is included on every SurgePV paid plan.
Bankable yield and financial reports. OpenSolar’s financial modeling covers basic ROI for residential. For C&I projects above 200 kW, lenders typically ask for a PVsyst-grade bankable yield report, which OpenSolar does not produce natively. 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, with P50/P75/P90 yield outputs that lenders globally already recognise. Carbon offset reporting is built in for ESG-conscious buyers.
Clara AI, the natural-language design assistant. OpenSolar’s interface is canvas-driven and does not yet support natural-language design. Clara accepts plain English commands. “Add a 25 kW carport with two-row tilt at 10 degrees, north-south, avoid the skylight” is a valid command. Industry analysts at pv magazine flagged natural-language design assistants as the single biggest workflow shift in solar software through 2026.
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 installer team can run end-to-end without a separate spreadsheet anywhere.

Common Mistakes When Pricing OpenSolar
We have helped several installer partners cut over from a stacked OpenSolar setup to SurgePV. These are the five mistakes installers make when they try to price OpenSolar honestly, scored by frequency.
-
1
Treating "free" as the real price. The OpenSolar free tier does not include white-label proposals, e-signature, advanced shading, or financing integrations. Price your stack with every add-on switched on before you compare to alternatives.
-
2
Ignoring the second licence for C&I. If you ship any project above 200 kW, OpenSolar alone will not clear lender bankability review. Add the PVsyst or similar licence cost to your real OpenSolar TCO, typically another €500 per user per year.
-
3
Underestimating the integration tax. If you run OpenSolar plus a separate CRM plus a separate proposal tool, the glue work (Zapier, manual handoff, lost leads) costs designer time. Count two to four hours per week per designer in lost productivity.
-
4
Missing the India tariff gap. OpenSolar's tariff library is strong for US, UK, and Australia. PM Surya Ghar subsidy auto-calc and DISCOM-specific net metering rules are not native. SurgePV ships these built in.
-
5
Forgetting the onboarding cost. Two to three weeks of designer time before a new hire is productive on a multi-tool stack is real payroll. SurgePV's 1-day onboarding window cuts this by 90%.
These mistakes are the same pattern we see when installers try to price any modular SaaS. We covered the broader lessons in our writeup on common mistakes EPC companies make in rooftop solar and they apply word-for-word to a design-software migration. For a side-by-side switch guide, see our OpenSolar alternative guide.
How the Migration Works (5 Steps)
The full OpenSolar-to-SurgePV cutover takes about five working days for a 5-person team. Run it in this order.
- 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.
- Export OpenSolar’s active projects. Export in-progress designs as PDF and the customer data as CSV. SurgePV’s importer ingests roof geometry from screenshots and address re-pulls satellite imagery cleanly.
- 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.
- Re-create your proposal template. Re-build the OpenSolar-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.
- Cancel OpenSolar add-ons at renewal. Once each designer has shipped 2-3 SurgePV projects (typically within 5 working days), cancel your OpenSolar add-ons and downgrade the base account. The cost saving usually recovers the first month of SurgePV billing immediately.
📘 Regulation note
If you are operating in India, SurgePV's code library includes IS standards and built-in PM Surya Ghar tariff modeling, which is now mandatory for any residential subsidy proposal under MNRE and PM Surya Ghar guidelines.
Who Should Stay on OpenSolar (Honest Pros and Cons)
We are recommending the switch, but there is a real scenario in which staying on OpenSolar makes sense. Here is the honest view.
- ✓ You are a solo installer doing 1-2 residential systems a week
- ✓ You operate only in US, UK, or Australia residential
- ✓ You do not need bankable yield reports for C&I lenders
- ✓ Your customers accept proposals without white-label branding
- ✗ Your team is 3+ designers and growing
- ✗ You ship projects above 200 kW or in India / EU / LATAM / Middle East
- ✗ You have switched on three or more paid add-ons
- ✗ You want AI 3D roof and bankable simulation without a second licence
In every scenario except the first, SurgePV is the better tool at the better price. The Indian solar market specifically, where Mercom India projects 25 GW of new rooftop installations through 2027 and the IEA tracks India as the third-largest solar market globally, rewards installers who can ship designs faster, cheaper, and with bankable simulation built in. Global capacity data from IRENA confirms the same shift across emerging markets.
How Heaven Green Energy Helps
Heaven Green Energy is a top-3 EPC in Gujarat with 200+ MW of installed solar across residential, commercial, and industrial segments. We use SurgePV internally because it gives our 12-person design team the bankable engineering rigour our lender partners require, without forcing us to keep three separate licences live for shade analysis, design, and proposals. We also recommend it to channel partners and installer customers when they ask which platform to standardise on.
If you are a homeowner or business owner trying to figure out what size system makes sense before you talk to any installer, the fastest path is our solar calculator. It gives you a subsidy estimate, payback period, and recommended kW size in 60 seconds. If you want an actual engineered design, site survey, and turnkey installation, here is what we offer:
- Residential Solar, 1 to 10 kW rooftop systems with PM Surya Ghar subsidy handled end-to-end and SurgePV-bankable yield reports included.
- Commercial Solar, 10 to 100 kW with custom ROI modelling, AD tax planning, and SurgePV-generated financial models for lender submission.
- Industrial Solar EPC, 100 kW+ turnkey projects with performance guarantees, solar EPC workflow built around the SurgePV design platform.

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 on choosing the right tool, see our guides to the best solar design software, solar proposal software, Aurora Solar alternative, HelioScope alternative, PVsyst alternative, and Scanifly alternative, or our 2026 ranking of top solar inverter companies in India. Additional market context from Bridge to India confirms the trend toward integrated single-license platforms.
Frequently Asked Questions
Is OpenSolar actually free?
The OpenSolar design tier is genuinely free for residential design without branded proposals. The moment you add white-label proposals, e-signature, advanced shading, financing integrations, or the CRM module, you move into paid add-ons at $20 to $40 per user per month each. A realistic installer stack with all five add-ons switched on lands at $80 to $150 per user per month, or $24,000 to $30,000 a year for a 5-seat team. The headline “free” is accurate for solo residential hobbyists, misleading for working installers.
How much does OpenSolar pricing cost for a 5-person team in 2026?
A realistic 5-person installer team running OpenSolar with the five common add-ons (advanced shading, white-label proposals, e-signature, financing integrations, CRM) pays $24,000 to $30,000 per year. That is before drone hardware, second-licence cost for PVsyst-grade bankable simulation on C&I projects, or onboarding time. SurgePV’s 5-User Team plan is a flat $6,495 per year all-in, with every comparable feature bundled, which works out to 75% to 85% cheaper on the same workload.
Does OpenSolar have AI 3D roof modeling from satellite?
No. OpenSolar’s design canvas requires manual roof outline tracing and manual obstruction placement. There is no automatic 3D roof model generated from satellite imagery. SurgePV pulls satellite imagery on address entry and builds a 3D roof model with obstructions detected automatically in under 60 seconds, with accuracy within ±3% of LIDAR ground truth. This single feature typically saves a designer 10 to 20 minutes per residential project and 30 to 60 minutes per C&I project.
Can OpenSolar handle C&I projects above 200 kW?
Partially. OpenSolar’s design engine works on C&I roofs, but the bankable yield simulation output that lenders ask for (PVsyst-grade P50/P75/P90, hour-by-hour module-level) is not native. Most installer teams shipping C&I above 200 kW end up running PVsyst alongside OpenSolar, which adds another €500 per user per year and doubles the licensing problem. SurgePV runs the same 8,760-hour module-level simulation natively on every paid plan, so one tool covers residential and C&I.
Does OpenSolar support PM Surya Ghar subsidy calculation?
OpenSolar’s tariff library is strong for the US, UK, and Australia. India-specific tariff structures, PM Surya Ghar subsidy auto-calc, and DISCOM-specific net metering rules are not native and require either custom configuration or external spreadsheets. SurgePV ships PM Surya Ghar, FiT, ToU, and net metering tariff models built in for all four major markets including India. This matters because the MNRE-approved subsidy proposal has to clear DISCOM scrutiny on yield and tariff assumptions.
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 OpenSolar within a week of trying it on their own pipeline, because the time-to-first-finished-proposal benchmark is so much shorter than a stacked OpenSolar workflow.
How does SurgePV pricing compare to OpenSolar add-ons?
SurgePV’s published 2026 pricing is $1,899 per user per year (Individual), $1,499 per user per year (3-User Team), $1,299 per user per year (5-User Team), and custom Enterprise. Every plan bundles AI 3D roof, 8,760-hour shading, single-line diagrams, BOQ, DXF/DWG export, branded proposals, Clara AI, and full country code libraries. A 5-seat team pays a flat $6,495 a year. A 5-seat OpenSolar team with realistic add-ons pays $24,000 to $30,000 a year for less feature coverage. The math favors SurgePV by 75% to 85%.
Does SurgePV handle CRM and lead management?
SurgePV focuses on design, engineering, and proposals. For CRM, lead routing, follow-up automation, and PM Surya Ghar subsidy paperwork, the natural pairing is QuickEstimate, a sister-brand solar CRM built for installer sales workflows. SurgePV plus QuickEstimate gives a 5-person installer team a complete design-to-signed-deal stack in two tools rather than the four or five most installers run on the OpenSolar add-on path. The combined cost is still well below a stacked OpenSolar plan.
