Lunar Energy

Lunar Energy is a Mountain View, California-based home energy technology company founded in 2020 by Kunal Girotra, the former head of Tesla Energy. The company's flagship product is the Lunar System - a fully integrated, ground-up-designed home energy platform combining battery modules, power electronics, and intelligent software in a compact, wall-mounted form factor. Unlike competing solutions that bolt together components from multiple vendors, the Lunar System is engineered as a unified end-to-end architecture that seamlessly manages solar generation, battery storage, EV charging, and household loads. The company also acquired Moixa, a UK-based distributed energy software firm, adding a fleet of over 35,000 managed residential battery systems in Japan and the UK, and incorporating the Gridshare software platform for AI-powered virtual power plant (VPP) management.

Lunar's technology goes beyond simple backup power. The Gridshare platform uses AI to optimize when batteries charge and discharge relative to solar production, utility time-of-use rates, and grid signals - enabling homeowners to cut electricity bills by up to 80% while participating in VPP programs that help utilities manage grid stress. Lunar has partnered with Octopus Energy for a dedicated battery electricity plan and with Sunrun to deploy VPPs across markets from New England to Hawaii. The company also has a strategic partnership with LG Energy Solution for battery cell supply, and operates a 35,000 sq. ft. manufacturing facility in Mountain View.

For the US energy supply chain, Lunar Energy represents a critical link between distributed solar generation, battery storage hardware manufacturing, and grid-interactive software. As the grid faces rising demand from electrification and extreme weather events, residential batteries aggregated into VPPs can function as dispatchable clean capacity - reducing reliance on fossil-fuel peaker plants. Lunar's deep-pocketed strategic investors (including solar giant Sunrun and South Korean conglomerate SK Group) and its $532M+ in total financing signal strong conviction in its vertically integrated approach to home electrification at scale.
