Residential solar upfront net subscriber value measures estimated upfront financing proceeds less Creation Costs per new Subscriber Addition.

Sunrun reported $2,692 per Subscriber Addition of Upfront Net Subscriber Value for the fourth quarter of 2025.

The reported value implies about $43,759 of upfront proceeds

Creation Cost per Subscriber Addition was $41,067.

Adding the $2,692 net value back to Creation Cost implies approximately $43,759 of upfront financing proceeds per Subscriber Addition under the metric's bridge.

Upfront proceeds are below full contracted value

Contracted Subscriber Value was $47,988.

The implied $43,759 upfront proceeds were about $4,229 below that modeled contracted present value, illustrating why Upfront Net Subscriber Value is not simply Contracted Subscriber Value minus Creation Cost.

This is not free cash flow or net income

The metric depends on estimated financing proceeds and issuer-defined Creation Costs.

Use Creation Cost per Subscriber Addition and Contracted Subscriber Value to keep the bridge's inputs explicit.

Part of the Residential Solar & Storage Subscription Economics

Connects residential solar and storage deployment growth with subscription mix, per-subscriber creation economics, network capacity, and the discounted value of contracted and modeled subscriber cash flows.

Where this concept fits

Subscriber unit economics and earning-asset valueCurrent relationship
Contracted Subscriber Value and Creation Cost determine near-deployment economics, while Subscriber Value adds modeled upside and Gross Earning Assets extend discounted cash-flow assumptions across the existing subscriber base.

Customer growth, subscription mix, and deployment volume
Customer Additions split between subscription customers and system purchasers, while Subscriber Additions feed the long-term Customer Agreement base. Solar and storage capacity measure the physical deployment produced by that customer growth.

Storage adoption and cumulative network scale
Storage Attachment Rate describes the mix of new customers taking batteries, while Networked Solar Capacity captures cumulative deployed solar scale across the installed network.
