Who Solargraf is best for
Installers who file many permits
Automated permit package generation is a named feature, which suits a company where preparing documents for the permit office takes as long as designing the system.
Mixed residential and commercial sellers
Commercial (C&I) project support sits beside residential design, so one subscription covers both a home battery job and a business rooftop quote.
Sales teams working in several languages
The vendor lists support for 16 languages, which matters for a company whose customers or staff do not all read English.

What Solargraf does
- AI-assisted design
- The vendor describes AI-powered solar design for solar and battery systems, so a first layout can be drafted automatically before a designer reviews and adjusts it.
- Sol assistant and agentic creation
- An assistant called Sol and an agentic AI solution that creates projects from commands are named on the homepage, though the page gives no example of the commands supported.
- Permit packages
- Permit package generation is described as automated, which moves a design toward submission without rebuilding drawings in another application, though the pages opened do not list which jurisdictions are covered.
- Proposals with financing
- Proposals support real-time editing and integrated financing, including Propel and TPO options, so a seller can change the system on screen and see the offer update.
- Production modelling validation
- The homepage cites third-party validation of its production modelling by the National Laboratory of the Rockies, formerly NREL, which is a validation claim rather than a certification.
How Solargraf handles your data
The pages opened do not state whether customer data is used to train models, how long data is retained or where it is hosted, and they list no security certification. The only assurance named is a third-party validation of production modelling by the National Laboratory of the Rockies, which concerns calculation accuracy rather than data protection. The maker and country are also not stated on the pages opened, so a European buyer who needs a data processing agreement should ask who the contracting entity is before signing.
Where Solargraf falls short in practice
- API costs extra. Public API access is a $4000 annual add-on on lower tiers and included only on Enterprise, so integrating with a CRM adds a large fixed cost to a Starter plan.
- Entry price. Starter at $2799 per year is above the $1,620 annual Basic seat at Aurora Solar and the $1,899 Individual seat at SurgePV, which weighs on a small installer's budget.
- Conflicting price statements. The homepage says pricing is not published while the pricing page lists tiers, and a Customize your plan option has no price, so confirm the figure by email.

Alternatives to Solargraf
Solargraf: common questions
How much does Solargraf cost?
The pricing page lists Starter at $2799 USD, Small Business at $4799, Teams at $6399 and Enterprise at $12999, all billed annually. The homepage says pricing is not published, so the two pages disagree. Confirm the current figure and what each tier includes before you buy.
Does Solargraf charge for API access?
Yes on lower tiers. The pricing page lists the Public API as a $4000 annual add-on and includes it on Enterprise. A team that wants to connect Solargraf to its own systems should compare that fee with the tier price and with competitors that bundle an API.
What AI does Solargraf name?
The vendor names AI-powered solar design, an assistant called Sol and an agentic AI solution that creates projects from commands. The pages opened give no accuracy figures or examples, so ask for a trial project to see how much of a design the AI completes.
Does Solargraf support commercial projects?
Yes, the vendor lists commercial (C&I) project support alongside residential design, and also lists proposals with integrated financing including Propel and TPO options. The pages opened do not say how large a commercial system the tool handles, so test it on a representative job.
Who owns Solargraf and where is it based?
The pages opened do not state the maker or the country, so this site does not name either. For a buyer that needs a contracting entity, a data processing agreement or a hosting region, the answer has to come from Solargraf directly.
