Distributed solar installer Redball Energy, based in Washington, DC, has a majority stake acquired by Rest and Wollemi Capital. The investment amount was not disclosed.

Why it matters

For Mid-Atlantic and New England households and businesses with rooftop panels from Redball, the change is ownership, not service, as the company is backed by new investors. The deal also signals that Redball plans to grow across the Mid-Atlantic and Northeast and add battery storage.

Redball operates around 4,500 rooftop solar systems across the Mid-Atlantic and New England, and the company was founded in 2021. The purchase price was not disclosed, and the timeline for its planned Northeast expansion has not been given.

The players

Redball Energy

A Washington, DC-based distributed solar firm that owns and operates around 4,500 rooftop systems and is the company whose majority stake was acquired.

Rest

An Australian investor that is investing in Redball through a Wollemi-managed co-investment fund.

Wollemi Capital

The investment firm that acquired the majority stake in Redball and manages the co-investment fund used for the deal.

MPower

An Australian distributed solar and storage platform in which Rest and Wollemi recently expanded their A$350m investment.

The details

Rest and Wollemi Capital acquired a majority stake in Redball Energy, a distributed solar firm based in Washington, DC. Rest is making the investment through a Wollemi-managed co-investment fund. Redball works closely with a select group of trusted local installers, and the new capital supports its plans to expand across the Mid-Atlantic and Northeast and add battery storage.

Timeline

  1. Redball Energy was founded in 2021.

  2. Rest made its A$230m cornerstone commitment to Wollemi's inaugural managed vehicle in July 2025.

  3. The majority stake acquisition in Redball was announced on November 13, 2026.

The District View

The deal follows the same investors' A$350m expansion of MPower, an Australian distributed solar and storage platform. It extends that strategy into rooftop solar in the Mid-Atlantic and New England, with a District-headquartered company as the vehicle.

If you have rooftop panels from Redball, your service and contract stay with the same company, now under new ownership. Ask your installer whether any changes to billing or service terms come with the new owners as the expansion takes shape.

The takeaway

Redball's deal is a sign that distributed solar is drawing larger investors into the Mid-Atlantic market. Watch for announcements on battery storage and new Northeast service areas if you live in the region.
