OpenSolar Pricing 2026: True Cost of Free

OpenSolar starts free, and OpenSolar describes its model as free to installers funded through partner and marketplace relationships. Here is how the total cost stacks up at C&I and how the flat-priced SurgePV alternative compares.

OpenSolar leads with a free tier and publicly describes its model as free to installers, funded through partner and marketplace relationships rather than seat fees. This guide breaks down the real cost math and shows the head-to-head against SurgePV at flat per-seat pricing. For the feature-by-feature comparison, see our OpenSolar alternative guide and the broader solar design software pricing roundup.

  • SurgePV ships the same residential workflow plus engineering depth at $1,299 to $1,899 per user per year flat.

OpenSolar Pricing Structure

OpenSolar pricing structure by tier
TierPriceNotes
Entry (Free)$0Simple residential, simplified shading
Pro / add-onsPer featureProposal templates, design extensions
Partner-funded modelNo seat feeVendor describes it as free to installers, funded via partners

OpenSolar does not publish a single seat-based price for the full feature set. The realised cost is the sum of paid add-ons used.

What Is Limited in the Free Tier

  • A lighter shading analysis model rather than a full 8,760-hour module-level run
  • Positioned around sales and design rather than project-finance reporting, so P50, P75, P90 evidence usually comes from a dedicated simulation tool
  • Multi-country code coverage narrower than tools built for multiple markets
  • Advanced proposal templates offered as paid add-ons at time of writing, a gap covered in our solar proposal software guide
  • Integrations delivered through OpenSolar’s partner network

Feature scope changes often, so confirm the current free-tier boundaries with OpenSolar before you plan around them.

For full PV simulation, bankable yield reports, and a hardware-neutral database, SurgePV’s flat plan is the typical upgrade path, the same methodology detailed in our PV yield simulation software guide.

Realised Cost: a Real Installer Math

A residential installer doing 10 systems per month per designer, mostly straightforward roofs with occasional C&I.

  • OpenSolar free plus paid extensions at 10 systems per month: roughly $80 to $150 per month in realised cost = $1,000 to $1,800 per year per seat
  • SurgePV Individual: $1,899 per year flat, full feature set, no add-ons

At 5+ projects per designer per month with any C&I in the mix, the realised cost on OpenSolar typically matches or exceeds SurgePV’s published seat price, and SurgePV includes bankable simulation and the integrated proposal stack at that price.

Total Cost: OpenSolar vs SurgePV at Team Size

Realised annual cost by team size: OpenSolar vs SurgePV
Team sizeOpenSolar realised costSurgePV plan
1-seat solo$1,000 to $1,800 per yearSurgePV Individual: $1,899 per year
3-seat team$3,500 to $6,000 per yearSurgePV 3-User Team: $4,497 per year
5-seat team$6,000 to $10,000 per yearSurgePV 5-User Team: $6,495 per year

At every team size past pure solo small-residential, SurgePV’s flat plan matches or beats the realised OpenSolar cost while shipping bankable simulation and integrated proposals.

What You Get for the Same or Less With SurgePV

Who Should Choose Each

  • Choose OpenSolar free if pure small residential with simple roofs is your entire scope and the partner-delivered integrations suit your workflow.
  • Choose SurgePV if you run 5+ systems per designer per month, design any C&I work, or want bankable simulation and integrated proposals.

For most installers in 2026, SurgePV is the alternative that wins on engineering depth, hardware neutrality, and realised total cost at the same time.

FAQ

Frequently Asked Questions

Is OpenSolar really free in 2026?
OpenSolar's entry tier remains free at sign-up. OpenSolar publicly describes its model as free to installers, funded through partner and marketplace relationships rather than seat fees. For pure small-residential installers running simple roofs, the free tier can still be net-zero cost. For installers scaling past simple residential, the realised cost typically crosses $1,000 per user per year once add-ons are included.
What does OpenSolar Pro cost?
OpenSolar does not publish a single all-in seat fee for the full feature set. Some capabilities, such as advanced proposal templates and certain design extensions, are offered as paid add-ons at time of writing, so the total varies by feature mix. Confirm the current add-on list and prices with OpenSolar directly. SurgePV's flat plan at $1,299 to $1,899 per user per year includes the equivalent feature set with no add-ons.
Is OpenSolar's free tier sufficient for an installer doing 10 projects a month?
For pure residential with simple roofs and no need for bankable simulation, yes. Once projects include complex shading, C&I rooftops, or PPA-funded work, the free tier hits a ceiling. The realised cost with add-ons typically clears the SurgePV flat plan at that volume.
Does OpenSolar produce bankable yield reports?
OpenSolar is positioned around sales and design rather than project-finance reporting, so teams raising debt generally produce P50, P75, P90 evidence in a dedicated simulation tool. Its shading model is lighter than a full 8,760-hour module-level engine such as PVsyst's or SurgePV's. Confirm what your lender requires before choosing.
What hidden costs are there in OpenSolar pricing?
The line items to budget for are paid proposal templates, advanced design extensions, and the time cost of stitching several tools together for simulation and financials. Add-on availability and pricing change, so price your own feature mix with OpenSolar. SurgePV's flat per-seat plan bundles the equivalent scope into one number.
How does OpenSolar pricing compare to SurgePV?
For pure small residential, OpenSolar free can be cheaper than SurgePV's flat plan. For installers running 5+ systems per designer per month or growing into C&I, the realised cost of OpenSolar plus add-ons typically matches or exceeds SurgePV's $1,299 per user per year, and SurgePV includes the full 8,760-hour simulation and P50, P75, P90 reporting in that price.
How do I switch from OpenSolar to SurgePV?
Book a free SurgePV demo, run a 4-week parallel migration, and drop the OpenSolar add-ons once your team is comfortable. SurgePV's AI 3D from satellite rebuilds site geometry in seconds, so the engineering setup phase is fast.
