Solar
We install up to 12 kW of high efficiency, all-black solar panels for a single, fixed price. Our aim is to provide you the highest capacity solar system your roof can reasonably fit* - we incentivize you to go big. Traditional $/Watt based pricing incentivizes the opposite, leading homeowners to install “just enough” solar capacity. Most installers in California currently charge $2-$5 for each additional Watt of capacity despite the actual cost being ~$0.7/Watt. This sends the wrong signal.
Over the coming decade most of our homes will double or triple in electricity consumption, so the right policy for sizing our rooftop solar systems is simple: as large as possible*.
* we will support placing panels anywhere the annual sun exposure is at least 700 ‘effective sun hours’ (anywhere 1.0 kW of solar panel rated capacity generates at least 700 kWh per year). This generally means we’ll place panels in moderate shade and on roofs facing any direction, just not in total / near-total shade.
Big battery
Everything changed with California’s recent policy shift away from “net metering”. The revenue we generate by exporting energy to the grid no longer matches the cost of the energy that we consume. We now get paid far less on average, but far more during certain periods of high grid stress. The key is to store solar energy and export it rapidly when the grid needs it the most. Enter the home battery.
All solar companies in California have begun to include home batteries in their proposals, but the battery systems they propose just aren’t big enough, and the price they charge is just too high! Our system has 2-3x the energy storage capacity and a lower total price.
Great investment
Higher earnings. A much larger battery system will yield higher bill savings and can simultaneously be used to generate additional revenue by providing ‘grid services’. We’ve built the right software to take full advantage of this, constantly working in the background to maximize the total earnings from the system.
Lower cost. We have optimized hardware costs, standardized our processes and streamlined all company operations around a single offering. We are committed to tackling the greatest problem in the US solar / storage industry - high “soft costs” (management, advertising, sales, legal, finance, design, permitting, inspections, and grid interconnection). It is primarily these soft costs which drive residential systems to prices 2-3 times that of Australia, Germany, and the UK. We firmly believe the only way to collapse these soft costs is to standardize everything - one system. one price. one process.
We offer unmatched financial returns. Consider the case of an average home (2000 sq ft) in which the roof can support ~20 panels, or 8 kW of solar:

High impact
The California electric grid cannot expand fast enough to allow electrification to proceed at the rate needed to meet climate goals. We have to make far better use of the grid we have, enabling it to move double or triple the energy it does today. This will require many thousands of grid-connected batteries capable of discharging on command, at high power, for multiple hours. It is this reality which primarily drove our design.
Our system can cover your home energy consumption while also exporting 10kW to the grid for a full two hours if the grid needs it. Essentially, each system shaves 10kW off the grid’s peak power demand problem, a much greater impact than most residential systems!
Resilient
In the event of a grid outage, our system immediately (20ms) switches over to supplying your full home from the battery system. You will receive a message notifying you of the grid outage and that power to your largest electrical loads (EV, heat pump, or water heater) has been cut off. It is then your choice whether to restore power to any of these large loads.
The 29 kWh battery system is large enough to carry you through the night with virtually no rationing of power. In the morning your solar will begin refilling the battery, and the cycle repeats until power is restored.
Straightforward
After months of research and experimentation we arrived at what we believe is the best approach to home energy for the majority of California homeowners. It is a huge burden to navigate the many hardware options, codes and restrictions, outdated rules of thumb, changing incentive programs, wide-ranging quotes, and deceptive financing options. We want to remove this burden for you by providing just one great option.
One system. One price. One process. Don’t let the complexity and lack of time cause you to delay another year! Take the straightforward (and best) option.
