About Solargraf
Solargraf is solar design, proposal and permitting software for installers. Enphase Energy owns it: Enphase bought Sofdesk, the Montreal company that built Solargraf, in January 2021 and still develops the product. From one account, a rep can design a system, build a proposal with financing, collect a signature and generate permit plan sets. Solargraf says more than 1,000 customers use it, and its site lists support for 16 languages.
The design side includes AI-assisted layouts, shading tools and battery design, and Solargraf's site says it covers both residential and commercial projects. Enphase says LightReach, EnFin and GoodLeap are fully integrated for third-party ownership (TPO) financing, and that NREL validated Solargraf's production modeling against measured PV system data (September 2025 announcement). It links to Enphase Enlighten, connects to DocuSign for e-signatures and offers a public API. In April 2026 Enerflo announced an integration that syncs Solargraf designs into its platform for US companies that subscribe to both.
Prices are published and billed annually per company. Starter is $2,799 a year for 2 users and 240 projects. Small Business is $4,799 a year for 4 users and 480 projects. Teams is $6,399 a year for 6 users and 720 projects. Enterprise is $12,999 a year for unlimited users and 1,500 projects. Extra projects cost $9 to $11 each and extra users $960 to $1,440 each (the page states no period), depending on the plan. Public API access is $4,000 a year on the lower plans and included in Enterprise.
Solargraf is not limited to Enphase hardware: its 2025 product recap says it supports more than 30 batteries, including all Enphase batteries. Enphase has also released it in the Netherlands, Germany, Austria and Japan. The trade-off: there is no monthly plan and no published free trial, so the entry cost is $2,799 up front, and busy teams need to watch the project and user limits. Installers who mainly sell other brands may want to compare it with tools such as Aurora Solar or OpenSolar.

Its starting price places it in our entry price band (under $100 per user per month).

Cost by crew size
Monthly cost of the cheapest Solargraf plan that allows each number of users, worked out from the plan prices and user rules on its pricing page, counting every tech as a full user. Plan prices and extra-user fees only: job, appointment and other usage limits, add-ons, setup fees and payment processing are not included; where a plan's usage limit is recorded, it is named under the figure. "Extra-user fee period not stated" means a plan that could cost less charges a fee for each extra user without saying whether the fee is per month or per year, so that crew size is not priced.
| Users | Billed annually |
|---|---|
| 1 | $233.25/mo Starter, 240 projects included, then $11 each |
| 3 | Extra-user fee period not stated Starter |
| 5 | Extra-user fee period not stated Starter |
| 10 | Extra-user fee period not stated Starter |

Key features
Integrations
Pros
- + Design to permit in one tool
Solargraf's pricing page lists proposals, shading tools, design, permitting, financing and a CRM on every plan, so reps and office staff work from the same project.
- + Owned by Enphase
Enphase develops Solargraf and links it to Enphase Enlighten, with Enphase-specific design options such as battery oversizing and power control support. That suits installers who sell Enphase microinverters and batteries.
- + Financing inside the proposal
Enphase says LightReach, EnFin and GoodLeap are fully integrated for TPO financing, so reps can show financing options in the proposal.
- + Published prices
All four plans and their overage fees are on the pricing page, which makes budgeting easier than with quote-only tools.
- + Independent check on production modeling
Enphase says NREL validated Solargraf's performance against measured PV system data and found accuracy comparable to NREL's own System Advisor Model.
Cons
- − Annual billing only
Every plan is priced per year, starting at $2,799, and the pricing page shows no monthly option or free trial.
- − Project and user limits
Each plan includes a set number of projects and users. Extra projects cost $9 to $11 each and extra users $960 to $1,440 each (no period stated), depending on the plan.
- − API access costs extra below Enterprise
The public API is a $4,000 a year add-on on Starter, Small Business and Teams. It is included only in Enterprise.
- − Enphase-specific features
Several features, such as Enlighten integration and Enphase battery oversizing, only help Enphase installers. Installers who mainly sell other brands should confirm their equipment and workflows are covered.
Implementation
Book a demo, since no self-serve trial is published. Pick a plan by counting both users and projects per year, and price out overage fees before you commit to annual billing. Set up proposal templates, financing partners and branding, then connect DocuSign from the External Integrations page. If you sell Enphase equipment, link Enphase Enlighten. If you need a CRM connection, check whether your CRM (for example Enerflo) already integrates, or budget for the $4,000 a year API add-on, which is included in Enterprise. Run a few past jobs through the design and production tools and compare the results with your current process before rolling it out to every rep.
