What SunStrong Management does

SunStrong Management is an independent full-service asset manager for distributed energy assets, established as a Delaware LLC in August 2024 and operating from Austin, Texas. The company was formed by solar-industry veterans to consolidate residential, commercial, and utility-scale solar portfolios orphaned by the wave of US solar company bankruptcies (>100 firms). SunStrong currently manages approximately 6 GW of distributed energy capacity across 500,000+ systems in 50+ markets, spanning continental US, Hawaii, Guam, and Puerto Rico, with portfolio concentrations in residential solar (~2 GW), commercial and utility-scale (~2 GW), community solar, EV charging, battery storage, and wind. Major portfolio acquisitions include 110,000+ former SunPower customers (Q3 2024), 400,000+ former Sunnova customers (Q3 2025), and a portion of former PosiGen customers (Q1 2026).

The company's core offering is an integrated asset management platform combining six service modules: contract servicing, billing and collections, field operations and maintenance, customer service, financial reporting, and tax and regulatory compliance. Supporting technology includes the SunStrong Connect mobile application (formerly mySunPower) with freemium and premium subscription tiers ($9.99/month or $99.99/year), and a Virtual Power Plant program aggregating residential battery assets for grid services in Puerto Rico (CBES), the Northeast (ConnectedSolutions in MA/CT/RI), and California (DSGS, SCE). Field operations use a hybrid model combining internal technicians with a national network of 50+ subcontractor partners for rapid response across distributed portfolios.

Revenue derives from managed services fees paid by capital partners and asset owners, transaction-based billing and collections revenue, professional services for field O&M, and recurring premium subscription revenue from the SunStrong Connect app. SunStrong has demonstrated capital markets access through two major asset-backed securitizations: $254 million in 2024 and $900 million in September 2025 (the largest solar ABS of 2025), backed by residential solar and battery loan collateral. Customer segments include capital partners and infrastructure investors (primary B2B), residential homeowners serviced through inherited originator contracts, and commercial/utility-scale asset owners. The company is registered as NMLS ID# 2677746 and serves customers through originator-specific billing portals (SunPower, Sunnova, PosiGen, GoodLeap).
