Ari J. Lauer is an American former attorney from Lafayette, California. He served as outside counsel to DC Solar, a Benicia, California company that operated what federal prosecutors called the largest criminal fraud scheme in the history of the United States District Court for the Eastern District of California.[1] Lauer advised the company from approximately 2009 to January 2019.[1]
DC Solar sold mobile solar generators to investors and claimed to lease them to third parties. The generators were marketed as a vehicle for federal solar tax credits and lease income. Most of the claimed rental revenue did not exist. New investor money was cycled back to earlier investors and disguised as lease payments. Investors put in roughly $759.4 million between March 2011 and December 2018. Related transactions exceeded $912 million.[1][2]
A federal grand jury indicted Lauer on October 5, 2023.[3] He pleaded guilty on October 14, 2025, one week before his trial was set to begin, to one count of conspiracy to commit wire and bank fraud, 12 counts of bank fraud, and 10 counts of wire fraud affecting a financial institution.[1] On March 9, 2026, U.S. District Judge Dale A. Drozd sentenced him to 11 years and 5 months in federal prison.[1][4]
Background
Lauer was a licensed California attorney.[3] He lived in Lafayette, in Contra Costa County. He was 59 at the time of his 2023 indictment and 61 when he was sentenced in 2026.[3][2]
His legal practice included corporate and business advisory work. From about 2009 he took on DC Solar as a client and served as the company's outside counsel.[1] He held that role for roughly a decade, until January 2019. During that period he provided what the government described as legal and business advice concerning the company's operations.[1]
The U.S. Attorney's office said his standing as a lawyer mattered to the scheme. His involvement "gave the scheme legitimacy and diminished any suspicion the investors might have had."[1] U.S. Attorney Eric Grant said, "Without the participation of Lauer, the DC Solar fraud scheme would never have been operational."[2]
DC Solar
DC Solar Solutions Inc. was based in Benicia, California. Jeff Carpoff, a former auto mechanic, founded the company in Concord in 2008.[4] He ran it with his wife, Paulette Carpoff.[4]
The company built mobile solar generators. These were trailer-mounted units that paired solar panels with batteries. DC Solar sold them to investors. The investors then leased the units back to DC Solar, which said it would sublease them to third parties such as cell carriers and sports venues. The product qualified for federal solar tax credits. That credit was the core selling point.[2]
The business attracted large institutional money. Among the investors was Warren Buffett's Berkshire Hathaway, which put roughly $340 million into the generators.[5] Federal agents raided DC Solar in December 2018. The company entered bankruptcy soon after.[4]
The Scheme
DC Solar claimed to have built about 17,000 generators with a stated value near $2.5 billion. The real number was far lower. Investigators found that thousands of the units never existed.[2] The company sold the same physical generators to multiple investors and pointed to inventory that was not there.[2]
Investors never took possession of their units. DC Solar held them and said it was collecting sublease income from outside customers. That income was largely fictional. Between March 2011 and December 2018, about 94 to 95 percent of the lease revenue on the company's books was intercompany transfers dressed up as new investor money.[1]
This is the mechanic of a Ponzi scheme. Money from new investors paid the returns promised to earlier investors. There was no underlying business generating those returns at the scale claimed. The Carpoffs spent investor funds on personal luxuries, including real estate, a private jet, and jewelry.[4]
Jeff Carpoff pleaded guilty in 2020. In November 2021 he was sentenced to 30 years in prison and ordered to pay $790.6 million in restitution.[2][4] Paulette Carpoff was sentenced to 11 years and 3 months.[4] A former chief financial officer and other associates were also convicted.[2]
Lauer's Role and Charges
Prosecutors said Lauer helped paper over the gap between what DC Solar promised investors and what the business actually produced. In June 2012, Lauer, Jeff Carpoff, and others met to discuss the company's failure to generate enough third-party lease revenue to meet its obligations to investors. The conspirators agreed to conceal that shortfall from current and prospective investors.[3]
To explain large movements of money between company accounts, the group created a "re-rent" arrangement. In 2014 they produced a re-rent agreement and backdated it to 2011. The transfers it purported to document were in fact new investor money being routed to earlier investors.[3] Lauer also took part in preparing sublease agreements that carried concealed addendums. Those addendums changed the terms of the contracts in ways that were hidden from investors.[3]
The October 5, 2023 indictment charged Lauer with 23 counts: conspiracy to commit wire and bank fraud, bank fraud, and wire fraud affecting a financial institution.[3] He pleaded guilty on October 14, 2025, with no written plea agreement. He admitted one count of conspiracy to commit wire and bank fraud, 12 counts of bank fraud, and 10 counts of wire fraud affecting a financial institution.[1]
The case was investigated by IRS Criminal Investigation, the Federal Bureau of Investigation, and the Federal Deposit Insurance Corporation Office of Inspector General.[1][6] Assistant U.S. Attorneys Audrey B. Hemesath and Nicholas M. Fogg prosecuted the case.[1]
Sentencing
U.S. District Judge Dale A. Drozd sentenced Lauer on March 9, 2026. The term was 11 years and 5 months, or 137 months, in the custody of the Federal Bureau of Prisons.[1][4]
The case stands as the largest criminal fraud prosecution in the history of the Eastern District of California.[3] Lauer was the last major figure charged in it.
His conviction ended his legal career. On December 19, 2025, the State Bar of California placed him on involuntary inactive status, which barred him from practicing law in the state.[4]
