OpenSolar: cost, fit and limits
OpenSolar is a solar design, sales and project management platform made by OpenSolar Pty Ltd that offers its core software to solar professionals free of charge, with auto design, bill of materials, proposals with integrated finance, e-signature and a CRM.
What to know first
OpenSolar presents its software as 100% free for solar professionals, covering design, sales and project management modules. Paid pieces are limited to an Enterprise Services add-on whose price and scope are not described on the homepage. The practical questions are data location, since the privacy policy names Australia and the US as possible storage, and the scope of the Chat with OpenSolar AI link, which the homepage does not explain.

Who OpenSolar is best for
Installers with no software budget
The homepage lists design, sales and project management modules as free of charge, so a new installer can run quotes and projects without a license fee.
Teams that finance every sale
The Sales Machine proposal includes CashFlow and integrated finance, which suits sellers who present a monthly payment option next to the system price.
Companies that need permits and plans
Mounting Designer, Single Line Diagrams and permitting integrations are listed on the homepage, which covers the drawings that follow a signed proposal.

What OpenSolar does
- Auto Design and Auto BOM
- Auto Design produces a first layout and Auto BOM lists the matching materials, so a quote can move from roof model to parts list without retyping, though the page does not say how the layout is generated.
- Mounting Designer
- The homepage lists a Mounting Designer alongside Single Line Diagrams, giving the technical drawings an installer or permit office expects in the same project file as the design.
- Sales Machine proposals
- Proposals carry CashFlow and integrated finance, with e-signature so a customer can sign inside the same flow, which shortens the step between presenting a price and starting the project.
- Project management CRM
- A CRM tracks projects after the sale, which keeps leads, designs and installs in one record instead of separate tools, at the cost of storing more of the business inside one vendor.
- Imagery Marketplace
- The homepage lists an Imagery Marketplace and permitting integrations, though the companies and imagery sources behind them are not named on the page opened, so coverage by region cannot be checked.
How OpenSolar handles your data
The privacy policy says personal data is kept for as long as reasonably necessary and that claims-related data is generally kept six to ten years depending on jurisdiction. It states that data may be stored outside the EU and names Australia and/or the US as locations, without describing one region for customers. The homepage links a Trust Center that was not opened, so certifications are not verified here. The policy does not say whether customer project data is used to train models, and the scope of the Chat with OpenSolar AI link is not described.
Where OpenSolar falls short in practice
- Unpriced add-on. Enterprise Services appears without a price or description, so a company that needs more than the free modules cannot estimate cost or scope from the homepage alone.
- Data location. Storage in Australia and/or the US, with no EU region stated, may not suit a European company that has to document where customer data sits.
- AI scope unclear. The footer links Chat with OpenSolar AI, yet no other AI capability is named, so buyers cannot tell whether layout or roof detection is automated by AI.

Alternatives to OpenSolar
OpenSolar: common questions
Is OpenSolar really free?
The homepage describes the software as 100% free of charge for solar professionals, covering design, sales and project management modules. An Enterprise Services add-on is listed with no price. Confirm in writing what your use case needs, because the page does not say how the add-on is billed.
Where does OpenSolar store customer data?
The privacy policy says data may be stored outside the EU and names Australia and/or the US. It does not name a specific region or hosting provider. European buyers who need a documented EU location should ask OpenSolar directly before moving customer projects in.
Does OpenSolar have an API?
Yes, the homepage lists an OpenSolar API, along with permitting integrations and an Imagery Marketplace. The pages opened do not describe API limits or terms, so check what endpoints exist for your CRM or accounting system before relying on it.
What AI does OpenSolar offer?
The footer of the homepage links Chat with OpenSolar AI, and no other AI capability is named on the pages opened. Auto Design and Auto BOM are listed as features, but the vendor does not call them AI. Ask for a demonstration if AI layout matters.
How long does OpenSolar keep my data?
The privacy policy says data is kept for as long as reasonably necessary, and claims-related data is generally kept six to ten years depending on jurisdiction. It does not give a fixed period for project data, so ask about deletion on request.
