Lunar Energy, established in 2020 by former Tesla Energy executive Kunal Girotra, develops integrated solar power and energy storage solutions for residential applications. Based in Mountain View, California, the company has built a team of 250 professionals dedicated to making clean energy accessible and efficient for homeowners worldwide. Their flagship product, the Lunar System, combines advanced battery technology with smart energy management capabilities, enabling users to generate, store, and optimize their energy consumption. The company’s mission focuses on transitioning homes to 100% clean energy through affordable and efficient hardware-software solutions.
Battery Technology
The Lunar System represents an advanced integration of battery and solar technology. At its core is a modular battery system that expands in 5 kWh blocks, providing flexible storage capacity based on individual household needs. The system includes a powerful 10 kW hybrid inverter capable of supporting entire residential power requirements, including HVAC systems.
The technology architecture consists of three main components: The Lunar Bridge, which serves as the central electrical panel managing power distribution and grid connection with sub-30-millisecond switchover capability; the Lunar Maximizer, which enhances solar panel efficiency; and the Lunar Battery, which stores excess energy for later use. This integrated system is controlled through the Lunar App, which employs predictive intelligence to optimize energy usage patterns and reduce costs.
Through collaboration with Eaton, Lunar Energy has enhanced its technology by incorporating smart breakers, simplifying installation processes, and improving load management capabilities. This integration allows for more precise control over energy distribution and consumption within homes.
Recent Projects
In early 2024, Lunar Energy announced a strategic partnership with Eaton to integrate AbleEdge smart breakers into their systems, with product availability expected in early 2025. The company has also established multiple virtual power plants across regions from New England to Hawaii, working alongside Sunrun to create networks of connected home energy systems that support grid stability and energy sharing.
Investors
Lunar Energy has secured $300 million in funding from prominent investors in the energy sector. The investment group includes Sunrun, a leading U.S. residential solar provider; SK Group, a South Korean industrial conglomerate; Itochu, a Japanese trading corporation; and Honda, which maintains a minority stake. This financial backing supports the company’s expansion and technological development initiatives.
