Percy’s power play: how an entrepreneur took control of his home energy

For Percy, energy isn’t just something you use—it’s something you measure.

“What you don’t measure, you can’t control,” he said, echoing the principle that guided his career as an engineer and three-time startup founder. “The Lunar System gives me that insight and control.”

Compact, power, and backed by people who care

When Percy upgraded his 20-year-old solar array, he knew what mattered most: finding a compact home battery powerful enough to back up his home during extended outages. Strict building clearances—three feet from windows—ruled out wider batteries with many boxes. 

Lunar Energy was the only system that met his needs. This is what mattered to Percy.

• Minimum of 20 kWh battery capacity housed in one sleek, narrow unit, enough capacity for a few days of an outage.
• Modular capability for future capacity add on.
• 10 kW inverter to power his entire home.
• Data analytics in an easy to use Lunar app plus built-in AI.
• Individual Solar panel monitors. His prior experience had shown that one poor performing solar panel in a chain can reduce the overall power output. Lunar Maximizers, installed behind every solar panel, provide intelligence to the system, monitoring each panel’s production. They work with any solar panel brand and ensure you capture the most power from the sun.

His engineering curiosity got him to tour the Lunar testing lab to assess material and build quality, and meet the Lunar team. 

“Seeing the guts and heart of the system made me confident Lunar Energy was not only setting a new standard, but that the final product would deliver on quality and reliability,” he recalls. “The individual employees were very diligent and committed that the end customers received a reliable product they could count on without worry.”

As with any upgrade, the total system installation and operation is critical. He used a Lunar recommended installer and the installation went smoothly. “My installer didn’t just sell me a battery, they backed it with real service and a quality team,” Percy added.

So many outages, yet none felt at home

Living in California means encountering outages more often than you’d think.

Since installing the Lunar System, Percy has gone through at least six outages—and none disrupted his daily life.

“My wife and mom didn’t even notice these power outages. I only knew because I got a notification through the Lunar App.” No lost food, no need for emergency lighting, no fridge panic. “It was enjoyable to see that everything was working as if nothing had happened. Clocks did not need a reset. I could not believe there was an outage and (using earthquake terminology) we did not feel it!”

“Life goes on without disruption. One less thing to worry about,” Percy said. “That’s what the Lunar System delivers.”

The hidden payoff: clean energy that pays back

Percy did his own total system cost analysis on the solar upgrade and the Lunar System. Percy’s Lunar System doesn’t just prevent disruption, it provides value he did not foresee nor include in his financial analysis:

• Solar charging for his BMW i4 during peak daylight, nearly grid-free charging.
• Real-time monitoring of solar production, home usage, and battery status—providing better prediction of PG&E utility charges per month.
• Extra earnings from the Virtual Power Plant (VPP) program and Lunar’s demand-side grid support (DSGS) programs where he gets paid for sharing stored power when it’s needed most, helping reduce strain on the grid.

“That VPP payout was unexpected, and it makes the financial picture even better,” he said. “There’s a real thrill in getting the VPP payout notice. You’re not just saving, you’re getting paid for helping the grid.”

Since enrolling in the VPP, he’s already participated in a few events, sending over 35 kWh of clean energy back to the grid and earning cash payouts. The Lunar App gives a snapshot of the VPP history at any given time.

“Through these events, I’ve almost dispatched two full battery loads. And this is just the beginning,” Percy shared. “The more events we join, the more impact to the community, the grid and overall increase in clean energy usage. The money payback is a definite plus.”

Why Percy chose Lunar

For Percy, it all comes down to visibility and control. 

“The Lunar App doesn’t just display the data, it lets me control how my energy is used,” he says. “I can choose what percentage of stored power to share through VPPs or switch battery modes as needed. Lunar AI mode is a smart addition that makes managing energy effortless.”

He also loves the independence that comes with generating his own electricity.

“Electricity is the only form of energy you can produce yourself. It’s impossible to generate other forms of energy, e.g. gas. I want to generate energy, use it, and share it, making my contribution towards a zero-footprint energy. Hopefully, with programs such as VPP and Lunar DSGS, it will be a negative footprint.”

Neighbors in his community often reach out for guidance, and Percy shares a few key tips:

• Choose one system with enough capacity for your whole home
• Find a system that is compact since wall space is at a premium in your house. 
• Choose a scalable system, one that can grow as your needs grow.
• Ensure the inverter size meets your load needs.
• Pick a system which has got hardware that can detect how the solar panels are functioning and can optimize solar power production.
• Work with a company that stands behind its product and you can go-to in case of issues.

For Percy, the choice was clear—Lunar Energy.

Percy’s experience and due-diligence makes it clear why homeowners are opting for the Lunar System:

• Reliable backup power in areas with frequent outages.
• AI energy management and real-time app controls.
• A scalable system, in one compact footprint on the wall.
• System approach to optimized power production (Maximizer + Battery).
• Integration with VPP and Lunar DSGS programs to boost payback.
• Supportive customer service that allows you to sleep well at night.
