The Solar Bankruptcy Wave Survivor Playbook

100+ Bankruptcies Since 2023: The Scale of the Wave

Over 100 US solar companies have filed bankruptcy or shut down since 2023, a wave the industry has not seen at this scale in roughly two decades. It is not one bad quarter. Titan Solar Power filed Chapter 7 in June 2024. SunPower Corp filed Chapter 11 two months later, selling its Blue Raven Solar brand and non-installing dealer network to Complete Solaria for $45 million (Complete Solaria later rebranded as "SunPower" in 2025, a different legal entity from the original). Lumio filed Chapter 11 in 2024. Sunnova and its financing partner Mosaic both filed Chapter 11 in June 2025. PosiGen ceased most operations in August 2025 and filed Chapter 11 that November, after serving 40,000 customers across 15 states. Freedom Forever, the #2 US residential installer with roughly 6.1% market share, filed Chapter 11 on April 15, 2026.

Employment tracked the same curve: roughly 21,000 clean-energy jobs were lost and more than $24 billion in investment was cancelled through September and October of 2025, with at least 1,691 solar-specific layoffs recorded via WARN notices that year. The US solar workforce still stood at 280,000-plus in late 2025, down from a record 464,053 in the 2024 National Solar Jobs Census.

What Actually Took These Companies Down

The failures do not share one single cause, but a few patterns repeat. Titan Solar Power grew through a dealer-network model tied to overselling and misrepresentation claims, coverage that later linked its collapse directly to commission-driven sales staff making exaggerated claims. Freedom Forever's bankruptcy landed days after Texas Attorney General Ken Paxton named it in an April 3, 2026 "major initiative" targeting solar companies for fraudulent and deceptive practices, on top of $500 million to $1 billion in liabilities across 3,600-plus employees and roughly 2 GW installed in 35 states.

Financing exposure compounded the sales-channel problem. Mosaic, a major solar loan and home-improvement financier, filed Chapter 11 the same month as Sunnova, and Mosaic was itself listed as a Freedom Forever creditor. When the lender that funds a dealer network's commission stack goes down at the same time acquisition costs are spiking, an installer already running thin on margin has nowhere to absorb the shock.

What the Survivors Are Doing Differently

Installers using outsourced 1099 dealer networks are facing the largest 2026 margin compression, while companies bringing acquisition in-house (direct D2D, paid search, referral) are preserving more margin per watt. That is the first pattern among the companies still standing: fewer arm's-length sales orgs between the installer and the homeowner, or at minimum, acquisition channels that do not depend entirely on one dealer network's health.

The second pattern is financing-agnostic pipelines. Third-party-ownership (TPO) structures, leases and PPAs, are surging (see the TPO shift guide for the full numbers), and installers still betting purely on cash-and-loan buyers are fishing in a shrinking pool. Survivors are pricing and pitching across all three paths instead of defaulting to loan-optimized sales scripts built for the pre-2026 tax-credit era.

The third pattern is customer lifetime value. Forward-thinking installers are shifting from one-time-sale economics to CLV models: battery upsells, EV chargers, roofing, and referrals, spreading acquisition cost across multiple products instead of a single solar-only sale. Battery attach rates hit 45% nationally in Q1 2026, up from 38% a year earlier, which makes this shift a real, sourced revenue lever, not a theory.

The Acquisition-Cost Math the Survivors Are Reacting To

Underneath all three patterns is one number: residential solar customer acquisition cost is spiking 40% to $0.84 per watt in 2026, after hitting a five-year low of $0.60/W in 2025. That 2025 low was an anomaly, a pre-25D-expiration demand rush that let installers coast on inbound while cutting marketing spend. That cushion is gone. Installers are now fighting harder for a genuinely shrinking pool of buyers, with the residential market forecast to contract 18 to 21% in 2026.

This is exactly the environment where a financing-agnostic, pay-per-sit appointment model earns its keep over a shared-lead vendor optimized for loan-qualified homeowners. An appointment that converts on cash, loan, or TPO is worth more per dollar spent than a lead that only pans out under one financing path, especially with the average solar loan dealer fee running around 22% in 2026, adding $5,700-plus to a typical loan balance before a single commission gets paid out of it.

A Survivor Checklist for the Rest of 2026

1. Audit how much of your pipeline depends on a single 1099 dealer network or financing partner, and build a second acquisition channel before you need one.
2. Price and pitch cash, loan, and TPO paths equally. A financing-agnostic pipeline converts through more of a shrinking market.
3. Treat compliance as a trust asset, not just a legal cost. Enforcement is already targeting the lead-generation layer, not only the installer brand.
4. Model CLV, not just first-sale margin. Battery, EV charger, and referral attach rates are the one growth line in an otherwise contracting market.
5. Watch dealer-fee compression closely if you run or buy into a dealer network; see the dealer-fee compression guide for the mechanics.
