What the Momentum Solar Case Actually Was
Momentum Solar, operating as Pro Custom Solar LLC, faced two combined class actions alleging it made unsolicited telemarketing calls in violation of the TCPA and state telemarketing laws. The class covered anyone who received two or more calls in a 365-day period between March 5, 2015 and January 2, 2025, a class definition wide enough to reach more than a decade of calling activity.
The case reached preliminary settlement approval on January 2, 2025, and final court approval on August 18, 2025, with the settlement fund set at $20 million to $30 million. That range, and the length of the class period behind it, is what makes this the case solar companies actually cite when the subject of TCPA risk comes up, not a hypothetical fine schedule.
Why This Case Is the One That Gets Cited
Momentum Solar was not the only residential solar company facing TCPA litigation. Sunpro Solar was separately named in its own class action over unsolicited calls. But Momentum Solar's case is the one with the largest disclosed settlement figure, the most recent final approval date, and a class period specific enough that any solar company running a long-running outbound program can see its own exposure in the numbers.
That combination, size, recency, and specificity, is why it functions as the reference case in this vertical the way a single landmark verdict shapes how an entire industry thinks about a risk, even when other cases exist alongside it.

Book a Solar CallThe Installer Is Not the Only One Exposed
A separate case covered by National Law Review, under the headline "Govern Yourself Accordingly: Solar Lead Company's Tough Guy Routine Appears to Backfire," involved a solar lead-generation company sued directly under the TCPA, not the installer whose brand ultimately closed the deal. The company's aggressive response to the initial complaint reportedly made its position worse rather than better.
That case matters beyond its specific facts: it is evidence that TCPA enforcement reaches the lead-generation and appointment-setting layer of this business, not just the installer whose name ends up on the contract. See the companion guide on lead-gen-layer liability for what that means if you are the one buying appointments from a vendor.
The Regulatory Backdrop Getting Tighter Around These Cases
Momentum Solar and the National Law Review case did not happen in isolation. The FCC removed more than 1,200 voice service providers from the Robocall Mitigation Database in August 2025 for deficient filings, a 2024 rule now lets consumers revoke calling consent through any reasonable method, and FTC Do Not Call complaint volume has been climbing. Each of those is its own compliance lever, covered in the companion guides on the Robocall Mitigation Database, the consent-revocation rule, and Do Not Call compliance.
Taken together, they describe a regulatory environment in 2025 and 2026 that is actively tightening around exactly the kind of outbound calling programs residential solar sales depends on, not loosening.
What This Means If You Buy Appointments Instead of Building an In-House Team
Buying appointments from a vendor does not transfer your TCPA exposure away entirely. If a vendor calling on your behalf runs an autodialer, skips consent documentation, or ignores an opt-out, the complaint tends to land on the business the homeowner recognizes from the call, which is often you, not a vendor name they never caught.
That is the practical argument for vetting how a vendor actually staffs its calls before price. VA Horizon's solar appointments are set by trained VAs dialing live, documenting consent and opt-outs as they go, the direct opposite of the robocall model behind the Momentum Solar case.
What this means for you
- Momentum Solar's TCPA class action settled for $20 million to $30 million, with final court approval on August 18, 2025, over unsolicited calls to a class covering March 5, 2015 through January 2, 2025.
- Sunpro Solar was separately named in its own TCPA class action. Momentum Solar is not an isolated case in this vertical.
- A National Law Review case shows the lead-generation layer, not just the installer, can be sued directly under the TCPA.
- Vetting how a vendor actually staffs and documents its calling, live-dialed versus autodialed, matters more than a verbal compliance assurance.
