Enphase Energy Supercharges Solargraf Platform With New TPO Partner Integrations, Faster Proposal Generation, Expanded Availability In Japan, And Validation From U.S. NREL

Enphase Energy, Inc., a global energy technology company and leading supplier of microinverter-based solar and battery systems, has announced significant upgrades to its Solargraf® platform. The enhancements include new integrations for third-party ownership (TPO) financing, faster proposal editing, and expanded availability in Japan. Solargraf is an all-in-one digital platform for proposal creation, system design, and permitting. It helps solar installers generate and manage professional proposals quickly and efficiently.

With the latest updates, Enphase aims to make it easier for installers to navigate evolving clean energy incentives and expand their customer base. The platform now incorporates advanced artificial intelligence for system designs, automated permits that are ready for local authority (AHJ) approvals, and fully customized proposals. The National Renewable Energy Laboratory (NREL) has validated Solargraf’s performance against measured photovoltaic system data, confirming its accuracy to be comparable with NREL’s own System Advisor Model. This independent verification underscores the platform’s reliability as a trusted solution for solar professionals.

The recent upgrades include full integration with several major TPO financing providers in the United States. EnFin, GoodLeap, and LightReach are now directly integrated into Solargraf, while EverBright and IGS also accept the platform. These integrations enable installers to instantly generate finance-ready proposals and take advantage of U.S. policy changes that increase the value of tax credits for TPO projects. A new Express Editor feature allows installers to make quick adjustments to proposals, whether in person or during virtual meetings. This helps them close deals faster and provide greater confidence to homeowners.

Enphase has also expanded Solargraf’s reach by launching the platform in Japan, complete with Japanese language support. This marks an important step in the company’s international growth, with plans to extend availability to India, France, and Australia in the coming months. Several solar companies have already reported benefits from the updates. Connor McFadden, director of strategy at Revolution Solar, said the enhanced features have reduced proposal revisions, improved sales efficiency, and ensured high-quality project delivery. Mark Hader, VP of sales at Go Solar Power, called the updates a “game changer” for their business, citing the Express Editor and new shading tools as particularly valuable for improving yields and layouts. Bernie Packard, CEO of Exo Energy, added that integrated financing options have significantly streamlined their sales process.

Looking ahead, Enphase plans additional improvements to Solargraf to further boost productivity and customization for solar professionals. Upcoming features include a better user experience for system design, integrated ordering and shipping for a complete bill of materials (including racking from top providers), and a custom tariff builder to help visually explain energy tariffs to homeowners. Jayant Somani, senior vice president and general manager of Enphase’s digital business unit, said the Solargraf platform is designed to reduce friction in solar sales, design, and permitting. He emphasized that the latest updates will allow installers to serve more homeowners with increased speed, flexibility, and transparency across multiple markets.
