The Cap Soleil Energie case is not limited to a series of scattered civil judgments. The structured criminal aspect, with an order from the Bobigny correctional court dated July 9, 2026, condemned the former leader and his companies to jointly compensate nearly fifty consumers for a total amount exceeding 750,000 euros in joint reparations. This figure marks a turning point: moving from individual disputes to mass litigation.
Designated credit and nullity of the order form: the central legal mechanism
Almost all decisions rendered against Cap Soleil Energie (now Génération Verte) rely on the same lever: the nullity of the order form for non-compliance with the Consumer Code. The order forms omitted mandatory information, particularly the precise technical characteristics of the panels, the conditions for executing the contract, or the terms of the right of withdrawal.
The direct consequence of this nullity is the annulment of the designated credit contract. The lending institution (Cofidis, Franfinance, or Domofinance depending on the cases) is required to refund the consumer all payments made, including principal, interest, and fees.
At the same time, the consumer must repay the borrowed capital, but this amount is practically offset by the seller’s obligation to refund the sale price. Several decisions have analyzed in detail the Cap Soleil Energie trial and confirm that credit institutions that released funds without verifying the regularity of the order form lose their right to reclaim the capital.
Deceptive commercial practices: the promises of self-financing sanctioned
The Bobigny correctional court classified the actions of the leader as deceptive commercial practices. The crux of the conviction lies in the promises of profitability made during home solicitation: self-financing of the installation through energy savings, resale of surplus to EDF OA at inflated rates, guaranteed return on investment within a few years.
These commitments, rarely formalized in writing, were reconstructed by the courts from converging sets of evidence:
- Financial simulations provided to consumers at the time of signing, showing unrealistic annual gains in relation to the installed power and local sunlight
- Consistent testimonies from dozens of complainants describing nearly identical sales pitches from one department to another
- The absence of mention, on contractual documents, of the actual expected yield or the climatic conditions necessary to achieve the announced performances
The criminal conviction regarding civil interests in Bobigny, targeting both the former leader and his companies jointly, sends a strong signal. It acknowledges the systemic nature of the deception, far beyond an isolated case.
CRPC and penal order: the procedural strategy of the leader
The order from the Bobigny correctional court dated September 15, 2025, was issued as part of a preliminary admission of guilt hearing (CRPC). This procedure requires the defendant to acknowledge the facts and accept the penalty proposed by the prosecutor. It is not trivial in a case of this magnitude.
The use of the CRPC allows for avoiding a public adversarial trial, with witness hearings and detailed examination of each contract. For the leader, this limits media exposure. For the victims, it accelerates the compensation phase but reduces the visibility of the debate on industry practices.
The decision in July 2026, concerning the civil interests of nearly fifty victims, complemented this aspect. The combination of CRPC followed by an order on civil interests remains rare in photovoltaic litigation, highlighting the seriousness of the case in the eyes of the prosecution.
Multi-jurisdiction civil convictions
Alongside the criminal aspect, the judicial courts of Saint-Nazaire, Béthune, Saumur, Metz, and Chaumont have each declared the contracts of Cap Soleil Energie or Génération Verte null and void. The unit amount of the convictions often hovers around 26,900 euros, corresponding to the standard price of a residential installation sold by the company.
This geographical dispersion complicates the company’s defense, which must mobilize advisors across the entire territory. It also reflects the extent of Cap Soleil Energie’s commercial network, which operated through home solicitation in many departments.
Prohibition of unsolicited telemarketing: what changes since August 2026
The regulatory context has caught up with the practices that fueled the Cap Soleil Energie litigation. Since August 11, 2026, unsolicited telemarketing is almost completely banned in France. Only professionals with explicit prior consent from the consumer can still make prospecting calls.
This ban directly targets the operating methods of companies like Cap Soleil Energie, which heavily relied on telemarketing and home solicitation to sell photovoltaic installations. The reform does not apply retroactively to ongoing cases, but it cuts off the main acquisition channel for these actors.
For solar professionals who operate properly, this evolution clarifies the competitive framework. It forces investment in compliant prospecting channels (incoming requests, qualified leads with consent, referrals from RGE craftsmen). Companies that continued to purchase unsolicited prospecting files now face heavy administrative penalties.
Consequences for the residential solar sector
The Cap Soleil Energie case is not an isolated incident. The judicial liquidation of Monabee, another player in the residential solar market, confirms the structural fragility of a segment where rapid growth has been financed by aggressive solicitation rather than by installation quality and word-of-mouth.
We observe three concrete effects on the sector. First, credit institutions are strengthening their controls before releasing funds, requiring compliance certificates for the order form. Second, professional liability insurers are reassessing the premiums of installers who engage in solicitation. Third, consumers now have abundant and consistent case law to contest irregular contracts.
The Cap Soleil Energie case has produced a legal corpus that can be utilized by any consumer faced with a photovoltaic installation sold based on unfulfilled self-financing promises. The decisions from Bobigny, Saint-Nazaire, and Béthune set references that will be difficult to ignore for courts handling similar cases.
