Enphase Expands Solargraf Platform With Financing, AI, and Japan Launch

Enphase Energy, Inc. (NASDAQ: ENPH) announced significant upgrades to its Solargraf® solar proposal and design platform, adding third-party ownership (TPO) financing integrations, faster proposal tools, and new market availability in Japan.

The enhancements come as U.S. clean energy incentives shift under the new federal budget framework, increasing the importance of streamlined financing and accurate project modeling. Solargraf now integrates with major TPO providers—including EnFin, GoodLeap, LightReach, EverBright, and IGS—with several offering direct, seamless financing inside the platform. The updates are designed to help installers maximize tax credit value and accelerate deal closures.

A new “Express Editor” allows solar professionals to adjust proposals in real time—whether in person or via video calls—while reducing revisions and boosting homeowner confidence. In parallel, the platform is now live in Japan, marking Enphase’s entry into a key solar growth market. Expansion into India, France, and Australia is expected in the near term.

Adding weight to the rollout, the U.S. National Renewable Energy Laboratory (NREL) independently validated Solargraf’s performance against real photovoltaic data, finding accuracy comparable to its own System Advisor Model. This validation enhances credibility for installers and financiers seeking reliable modeling tools.

Enphase emphasized that the upgrades aim to remove friction from the solar sales and permitting process, with future updates planned for system design, bill of materials ordering, and tariff modeling.

Solar installers have welcomed the changes. Revolution Solar noted reduced revisions and faster project completions, while Go Solar Power highlighted the benefits of faster proposal editing and improved shading tools. Exo Energy cited major efficiency gains from financing integrations.

Enphase, already the world’s leading supplier of microinverter-based solar and battery systems, is positioning Solargraf as a cornerstone of its digital ecosystem. With over 83 million microinverters shipped globally and 4.9 million systems deployed, the company is leveraging its scale to capture growth in solar software and services as markets transition toward cleaner, distributed energy.
