Home batteries are having a moment, but for years, getting one meant cobbling together a solar panel from one company, an inverter from another, a smart panel from a third, and hoping they'd all play nice. This week on Everybody in the Pool, Molly takes a field trip to Mountain View, California, to visit Lunar Energy, where founder and CEO Kunal Girotra has built the fully integrated solar-plus-battery ecosystem he always wished existed.

Plus: a tour of Lunar's working showroom, where we flip a breaker, watch the app react in real time, and find out what happens when you leave the oven on during a power outage.


We talk about:

  • Why Kunal left Tesla Energy to build a fully integrated home energy ecosystem
  • How Lunar's modular, stackable battery blocks work (think Lego bricks for your garage wall)
  • The real math on savings: how a solar and battery system can cut your bill by $2,000/year, and Lunar's AI adds another $500 on top
  • How "virtual power plants" are actually very real, and why Lunar wants to rename them "distributed power plants"
  • Why Northeastern states are leading on VPP policy, and what utilities in other regions need to change to keep up
