Financing can make or break a solar sale. When installers can present clear monthly payment options, align financing to the project type, and move quickly from proposal to fintech partner workflow, the customer experience improves and deals move faster. That is why Solargraf’s newest financing integrations matter.
Solargraf now supports three additional loan partners: Sunstone Credit, Sungage Financial, and Concert Financial, in addition to the existing financial partners Enfin, Goodleap and Lightreach. Together, these integrations expand the financing options available to installers across commercial and residential projects, while simplifying quoting and application handoff directly from the Solargraf platform.
For installers, the biggest advantage is simple: more ways to match the right financing product to the right customer without leaving the proposal workflow.
What these new integrations mean for installers
With these fintech partner integrations, installers can build proposals with financing options that are better aligned to customer needs, project scope, and sales strategy. Instead of relying on disconnected rate sheets or manual calculations, teams can present more consistent financing scenarios within Solargraf.
- Offer financing choices for both residential and commercial opportunities
- Present loan products designed for solar-only or solar-plus-storage projects
- Reduce friction between proposal creation and fintech partner submission workflows
- Improve confidence in sales conversations with clearer payment visibility
Sunstone Credit: Commercial financing built for larger solar projects
Sunstone Credit strengthens Solargraf’s support for installers working in the commercial segment. This is especially valuable for teams selling to small and medium-sized businesses, agricultural customers, non-profits, and other organizations looking for structured financing for larger clean energy investments.
Sunstone’s value is its focus on commercial solar financing. Unlike products built primarily for homeowners, these loan offerings are better suited to projects with more complex business considerations, longer decision cycles, and larger ticket sizes.
Types of loan products Sunstone supports
- Commercial solar loans for business-owned solar installations
- Standard loan options - regular amortized loans with one payment period
- Special payment loan options - two period loan with a special prepayment percentage
- Solar plus storage financing for projects that combine PV and battery storage
- Longer-term financing structures that can help align payments with projected operational savings

Why this matters to installers
Commercial customers often evaluate solar differently from homeowners. They may look at energy savings, capital planning, tax-related benefits, resilience goals, or facility upgrades as part of one broader business decision. Financing that is purpose-built for commercial projects helps installers present a more credible and relevant offer.
Inside Solargraf, this integration gives installers a cleaner path from project design to financing presentation for commercial deals, reducing the need for off-platform coordination.

Sungage Financial: Residential solar loans with familiar flexibility
Sungage Financial adds a strong residential financing option for installers focused on homeowners who want predictable monthly payments and straightforward loan structures. Sungage is well aligned with the needs of residential sales teams that want to pair financing with fast, customer-friendly quoting.
Sungage’s loan offerings are especially relevant for installers looking to serve a broad range of homeowner budgets and project sizes.
Types of loan products Sungage supports
- Residential solar loans for standard rooftop PV systems
- BrightStart DPP loans - Includes a deferred payment portion due at month 35 which can be used with select rebate options supported on Solargraf
- BrightStart Level Pay loans - Standard fixed-payment loan where monthly payment remains constant for complete loan term
- Sunrise loans - Escalator loan which start with an initial monthly payment and increase by 2.9% each year
- Solar plus storage loans for homeowners adding battery backup
- Flexible term options that can support different payment preferences

Why this matters to installers
For residential sales, speed and clarity are critical. Homeowners want to understand affordability quickly, and sales reps need financing options that can be presented confidently in the proposal itself. Sungage helps support that experience by making it easier to position solar as a manageable monthly investment rather than a large upfront cost.
For installers, this means another practical financing path for common residential use cases, including projects where storage is part of the conversation.

Concert Financial: Solar + financing for broader home energy projects
Concert Financial expands financing flexibility for installers selling more than just solar panels. Its Solar+ orientation makes it a strong fit for projects that bundle multiple home energy upgrades into a single financing conversation.
This is increasingly important as more homeowners consider batteries, electrical upgrades, and related energy technologies alongside solar. A financing partner that supports broader clean energy scope helps installers package a more complete solution.
Types of loan products Concert supports
- Standard & RBP based Solar loans for residential PV systems
- Solar plus storage financing for integrated resilience and backup power solutions
- Clean energy package loans that may also support complementary upgrades such as electrical improvements or EV-related components, depending on fintech partner program setup
- Options designed for wider homeowner qualification scenarios, supporting more financing conversations across different customer profiles

Why this matters to installers
Concert gives sales teams more room to build financing around the full project instead of isolating solar as a standalone purchase. That is especially useful when installers are upselling storage, preparing customers for electrification, or positioning solar as part of a broader home energy strategy.
For Solargraf users, this integration helps connect proposal creation with fintech partner workflow in a way that supports modern Solar+ sales motions.

Why this expansion matters now
Installer sales strategies are evolving. Some teams are going deeper into commercial projects. Others are expanding battery attachment rates. Many are looking for ways to offer more tailored financing options across different customer segments. Adding Sunstone, Sungage, and Concert to Solargraf helps support that shift.
Instead of forcing every project into a narrow financing model, installers can choose from a broader set of fintech partner profiles:
- Commercial-focused financing for business customers
- Traditional residential solar loan options for homeowners
- Solar+ financing for more comprehensive energy upgrade projects
That flexibility can help sales teams improve fit, reduce friction, and better align financing conversations with how solar is actually being sold today.
Final takeaway
The addition of Sunstone Credit, Sungage Financial, and Concert Financial along with exisiting financial partners Enfin, Lightreach and Goodleap, gives Solargraf installers access to more financing pathways across more project types. Whether your team focuses on commercial solar, standard residential installs, or bundled Solar+ offerings, these integrations help you present more relevant loan options within the same platform you already use to design and sell.
For installers, that means a simpler workflow, a stronger proposal experience, and more flexibility in how you bring financing into the sale.
