Residential solar upfront net subscriber value margin measures Upfront Net Subscriber Value as a percentage of Contracted Subscriber Value.

Sunrun reported a 5.6% margin for the fourth quarter of 2025.

The ratio reconstructs from the per-subscriber values

Upfront Net Subscriber Value was $2,692 and Contracted Subscriber Value was $47,988.

Dividing $2,692 by $47,988 gives approximately 5.61%, which reconciles to the reported 5.6%.

The denominator is modeled contracted value

This is not a margin on GAAP revenue.

Its denominator is Contracted Subscriber Value, a discounted present-value metric rather than recognized sales.

Unit-economics margin is not corporate profitability

The 5.6% figure is not gross margin, operating margin, net margin, or cash-flow margin.

Use Upfront Net Subscriber Value to inspect the numerator and Creation Cost to understand what sits behind it.

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.
