Mark's easy button for home energy

“It just works. If you never want to think about energy again, Lunar saves you money automatically. If you’re an energy nerd like me, you’ll love digging into the details.”

Mark had solar on his roof for over a decade. A self-proclaimed early adopter, he believed in the promise of clean energy long before it was mainstream. But for years, something felt missing.

“I had solar, but I didn’t feel like I had real control over my energy,” Mark said. “I couldn’t see what I was using, I couldn’t change my behavior, and I definitely couldn’t power my whole home in an outage.”

Mark, a venture investor with a technical Ph.D., isn’t easily impressed. He’s spent his career at the intersection of science, business, and sustainability. So when it came to adding a battery to his system, he spent five years searching—and rejecting clunky options that backed up just a few circuits or required a maze of decisions from an electrician.

“I didn’t want to choose which four things to power during an outage. I wanted a solar battery that backed up the whole house. One that just worked.”

Solar, battery, and brains—All in one

When Mark discovered Lunar, something clicked. “This was the first product I’d seen that actually solved the problem,” he said. “It was the residential electrification easy button.”

Lunar gave him what others hadn’t: a complete home backup, an app that showed exactly how his energy was being used, and a system smart enough to optimize when to use solar, battery, or grid—all on its own.

“It’s a really complicated system under the hood,” he added. “But the user experience? Incredibly simple.”

With one tap, Mark toggled into AI Mode. Now, Lunar’s software plans out the most cost-efficient use of energy, based on weather, household activity, and time-of-use rates.

“It knows what it’s doing. I wake up with a full battery. It charges when electricity is cheap. And in the evening, it pushes power back to the grid when rates spike,” Mark said. “It’s basically running energy arbitrage for me—while I make dinner.”

From blind spot to bright spot: the 5% of your budget you can finally control

As a father and sustainability-minded investor, Mark understands that energy isn’t just another bill, it’s a blind spot without any visibility or control.

Household utilities usually take up around 5%* of monthly spending—a small slice, yet often the most opaque. But that’s for typical households. For many low-income families, energy alone can eat up 8% or more of income, sometimes surging past 15%.

“Energy is the wallet’s blind spot,” said Mark. “Lunar changes that. You suddenly have insight, control, and the ability to make money back. You go from a passive consumer to an active participant.”

What Mark tells his friends

Mark isn’t shy about sharing facts about his Lunar System with neighbors.

“My pitch is simple. If you never want to think about energy again, it just works. Or if you’re a total energy nerd like me, the app is addictive and gives you so much insight.”

And when asked why he chose Lunar over the bigger names?

“I get this question a lot—‘Why not just get a Tesla Powerwall?’” Mark said.

“My answer is simple: the team behind Lunar built the Powerwall. Then they left and built something better—without the drama. The Lunar System is beautifully designed, works seamlessly, and doesn’t lock you into a closed ecosystem. It’s the residential electrification easy button. It just works.”

FAQ: Mark’s energy insights

1. Why not just stick with solar?

‍Solar alone doesn’t give you backup during an outage, and you’re still at the mercy of utility rates. That’s why Mark says pairing it with a battery is key to real energy freedom.

2. What’s different about Lunar AI?

‍According to Mark, “It’s incredibly smart.” Lunar AI automatically optimizes energy use by learning all the rate schedules and shifting power usage accordingly—charging when rates are low, discharging when they are high. As Mark says, “The rate schedules are getting more complex and something you just can’t manage and don’t want to manage. Lunar does it on your behalf.”

3. Can I still have control?

‍Absolutely. Mark toggles between Solar Self-Consumption and Lunar AI mode in the app. “I’m a total energy nerd,” he admits. “But I still find myself leaving it in Lunar AI most of the time since it just works best - saving me the most amount of money”

4. How does Lunar save money?

‍The Lunar System saves money by timing when you use, store, or sell energy. Lunar helps cut energy costs without requiring you to change how you live, especially during peak pricing windows.
