EnFin vs Mosaic Captive Finance vs Traditional
The Problem: As capital markets tighten, third-party solar lenders are raising dealer fees and tightening underwriting criteria. Installers who rely solely on pure-play fintech lenders are experiencing shrinking approval rates and margin compression on standardized equipment packages.
If your operational stack relies heavily on Enphase hardware, EnFin (Enphase's captive finance arm) is the strategic winner. By subsidizing the loan through hardware sales, EnFin offers superior dealer fee structures and higher approval rates for Enphase-specific equipment compared to traditional third-party lenders like Mosaic.

Lumen's Take
This is the 'Captive Finance' playbook. Automakers have done this for decades: Ford Motor Credit exists to sell Ford cars. Enphase launched EnFin to sell Enphase microinverters and batteries. If you are a dedicated Enphase installer, you are leaving money on the table by using a third-party lender like Mosaic. EnFin leverages their hardware margin to buy down your dealer fees. However, if you are hardware-agnostic, Mosaic's broader platform remains the more flexible choice.
