Maxwell Power, formerly known as HDM Renewable Finance, a company that provides financing for residential solar and battery storage systems, has announced that it has closed a $750 million investment commitment from Fairtide Partners to finance battery storage and solar power projects.

The funding announcement follows Maxwell’s rebranding from HDM Renewable Finance. The company said the rebrand reflects its shift from a residential solar and battery storage finance provider to a full-service consumer-facing power brand.

The capital is expected to help the company support sales and installation companies that offer advanced energy technologies to consumers. The investment will also support Maxwell’s planned expansion into new state markets where electricity costs have increased.

Maxwell said the new investment increases Fairtide’s total investment commitment for projects developed by Maxwell to more than $1 billion.

“Skyrocketing utility and gasoline costs are pinching everyone’s pocketbook,” said Dustin Dunaway, Maxwell’s Chief Revenue Officer. “Fairtide’s $1 billion commitment allows us to help more homeowners and businesses get affordable energy they can count on.”

The company did not disclose the investment structure, the number of projects it will support, or the expected deployment timeline.

Fairtide Partners cited Maxwell’s origination, underwriting, and management track record as factors behind the additional commitment, according to the company statement.

“We have worked with the Company’s leaders since 2010 and partnered with Maxwell since its founding in 2018,” said Nat Kreamer, Fairtide’s founder and lifetime chairman emeritus of the Solar Energy Industries Association. “Maxwell has a great track record of delivering high-quality assets that create value for consumers and investors.”

According to Mercom’s recently released Q1 2026 Solar Funding and M&A report, announced large-scale solar project funding increased by 61% in Q1 2026 compared with the same period in 2025.

In May 2026, IPX Power, an independent power producer, closed committed financing for the construction and operation of the Darden solar and battery storage projects in Fresno County, California. MUFG Bank, Banco Santander, Crédit Agricole Corporate and Investment Bank, Deutsche Bank, and Société Générale served as initial coordinating lead arrangers and joint bookrunners.
