The System

  • 8,000 Watts of high-efficiency solar panels. Sleek, all-black panels mounted flush to your roof for the cleanest aesthetic.

    When paired with our large battery system, 8,000 Watts of solar is enough to achieve near zero annual PG&E electricity costs, even for a fully electrified, midsize home.

  • A battery system with greater energy storage capacity (29 kWh) than a Tesla Powerwall plus Tesla DC expansion pack (27 kWh total)

    A battery system capable of exporting power at very high rate (16 kW), enabling earning of maximum export credits from PG&E.

  • Our system integrates into your home electrical system such that 100% of your appliances and outlets can operate during a grid outage.

    With such a large battery system included, you’ll have backup power for days.

  • An electrical panel with a monitoring app which tracks power draw from a handful of key circuits in your home, and allows circuits to be turned on or off.

    This new panel allows you to electrify your home without upgrading your main electrical panel! - this will save you 5,000 - 10,000 as you electrify your home over the coming years.

  • Standard NEMA 14-50 outlet for plugging in a wide array of plug-in EV chargers. Wired for 32A ( 8 kW ) continuous charging, more than enough for vast majority of drivers.

The Impact

The California electric grid cannot physically expand fast enough to allow electrification to proceed at the rate needed to meet climate goals.

In order for California to meet climate goals over the next 20 yeras, we HAVE to enable our existing grid infrastructure to move double or triple the energy it does today. This will require many thousands of grid-connected batteries absorbing excess energy when there is a surplus from renewable sources, and discharging energy when demand outstrips supply.

Our mission is to accelerate the deployment of high performance, grid-connected battery systems across California. With each system we install and operate, we increase the grid’s ability to balance supply and demand. Our goal is to contribute 1.0 Gigawatt of “grid balancing” battery resources by 2035.  If we can meet our goal, we can substantially improve the pace of electrification of the world’s 5th largest economy.  This is going to take the support of 85,000 PG&E homeowners over the next decade.

The Formula

  • We’ve standardized our offering and streamlined every aspect of our operations in order to deliver you the best value possible.  

    We’re obsessed with cutting out the enormous “soft costs” that have inflated the US residential solar industry for two decades.

  • Our system is tailored to earn PG&E homeowners maximum bill credits under PG&E’s universal Solar Billing Plan.

  • Our software manages the charge and discharge behavior of the large battery system in order to earn revenues from other “grid participants” (not PG&E). 

    We use this extra income to cover ongoing warranty and support costs for your system, and split the remainder with you.
