The $230M Bet on Turning Homes Into Power Plants | Lunar Energy

What if your home could cut electricity bills by 60%, survive weeks without the grid, and earn money while you sleep?Lunar Energy is building an integrated home energy system combining solar, batteries, load controls, and AI-powered software. Its GridShare platform already manages 650+ MW across 150,000 homes, including third-party hardware.Founder and CEO Kunal Girotra previously led Tesla Energy from 2015 to 2020, helping bring Powerwall into residential energy storage. He has since raised more than $230 million to build Lunar.Here’s what we discussed:How to turn homes into distributed power plants — Why combining batteries, solar, controllable loads, and virtual power plants can lower bills, provide backup power, and create new grid revenue for homeowners.Why software matters more than battery hardware — How Lunar uses device-agnostic software to manage its own products and third-party equipment across 150,000 homes and 650+ MW of capacity.How AI can cut electricity costs by another 10–15% — Why localized, real-time optimization against changing import and export prices outperforms basic solar-plus-storage self-consumption.Why leasing is becoming the default for home batteries — How zero-down financing, tax-credit changes, and immediate monthly savings have pushed roughly 80% of Lunar customers toward leases.How to raise $230M for a climate hardware company — Why proving product-market fit, securing Sunrun as both an investor and distribution partner, and demonstrating resilience under adversity mattered more than ambitious promises.--1️⃣ Join our confidential CEO community.Private CEO group for VC/PE-backed climate tech founders navigating capital, strategy, and scale.
