| Aug 2022 | Undisclosed stage | Sunrun; SK Group | $300M | - | Lunar Energy emerged from stealth in August 2022 as a Mountain View, California-based startup founded in August 2020 by Kunal Girotra, former head of Tesla's residential energy business. The company designs integrated home battery systems combining battery modules, power electronics, and custom software for residential energy independence, along with Virtual Power Plant (VPP) management platforms. In its 2022 Series A/B funding rounds, Lunar Energy raised a total of $300 million led by Sunrun, the nation's leading residential solar and battery storage provider, and South Korea's SK Group, with additional participation from Japanese trading conglomerate Itochu and automaker Honda. By August 2022, the company had assembled approximately 250 employees, constructed a 35,000-square-foot manufacturing facility in Mountain View, and acquired Moixa, a U.K.-based software company managing over 35,000 residential battery systems across Japan and the U.K. Lunar Energy's first product, a fully integrated home battery system, was expected to launch within months of the August announcement. The company's strategy focused on combining hardware and software capabilities to address the residential energy storage market, positioning itself against fragmented competitors that assembled components from multiple vendors. By 2026, Lunar Energy had expanded significantly, raising an additional $232 million across Series C ($130 million from Activate Capital) and Series D ($102 million from B Capital and Prelude Ventures) rounds, with its Gridshare platform managing the country's largest Virtual Power Plant programs and deploying thousands of systems across multiple states and international markets. |
